Introduction
ScriptCards provides a feature-rich scripting language built as a Roll20 API script and accessible via the Roll20 chat window and macro system. The normal ScriptCards output is a formatted "card" to the game's q Text Chat. While the visual style of the default output is themed after a D&D 4E Power Card, there is nothing game system specific in ScriptCards. The output is fully customizable, and entirely optional. Scripts can perform game object manipulation and never display anything if desired.
The ScriptCards language supports variables, looping, conditional statements, branching, functions/subroutines, persistence of data items, object modification, reentrant functionality and much, much more. It includes its own dice roll parser with a number of different rolling options.
ScriptCards is not game-system specific, and can be used with any system/sheet.
Current OneClick Version : 1.4.10
Note: As of 2022-02-13, ScriptCards 1.6.2 has been submitted for OneClick update. The documentation below is in the process of being updated for 1.6.2.
Current Development Version : 1.6.2
Critically Important: ScriptCards does not parse inline rolls. ScriptCards includes its own built-in dice roll parser to allow for the use of variables inside dice rolls. The final numeric value of an inline roll can be used in a ScriptCard, but only as a text substitution value, so inline rolls can't reference the value of ScriptCards variables.

Is ScriptCards Related to PowerCards?
I (Kurt J.) have been maintaining and updating PowerCards for a couple of years now, and ScriptCards isn't an effort to supplant PowerCards, but rather represents my effort to address some of the most common issues that PowerCards users run into because of the intrinsic nature of the way PowerCards was conceived and developed over time. ScriptCards is more of a follow-up to PowerCards. Perhaps the most frequent question asked in the PowerCards thread on the forum is something along the lines of “how do I use the result of THIS roll in the roll I make two lines later?” Unfortunately, due to the architecture of PowerCards, this isn’t possible.
Besides this issue, there are various elements of a PowerCards macro that can’t support certain features. For example, you can’t set most card-wide settings (name, leftsub, rightsub) dependent upon the results of a dice roll, and while I’ve implemented a simple “skip forward” mechanism in PowerCards to allow for some flow control, true branching (forward and backwards) is not possible due to the way cards are processed. While it might be possible to rewrite some of the core of PowerCards to allow for implementation of (some) of these features, the result would be a very different script that would not be backwards compatible with the host of users currently using PowerCards in their games.
Instead, I have taken the approach of writing a completely new script from the ground up. There is very little (if any) of the original PowerCards code included in ScriptCards because I am fundamentally changing the way the macro is processed. Note that this isn’t a slight against the original author of PowerCards (Sky). The script has been widely used for years now, and is a testament to the flexibility of the original code that I was able to add so many features over the past two years.
By implementing ScriptCards as a new, separate script, those using PowerCards as it currently exists can continue to do so without interruption, while those interested in the functionality of ScriptCards can make use of its updated feature set. The two script (PowerCards and ScriptCards) can happily coexist in the same game, and do not interfere with each other in any way.
Check the What to Know if you are Coming from PowerCards-section for a comparison table between the two scripts.
What is a ScriptCard Script
A ScriptCard script is text written into the q Text Chat (either typed directly, pasted, or run via a macro/character ability) that will be interepreted and executed by the ScriptCards language processor. In most cases, the result of the script will produce output displayed as an HTML formatted "card" in the chat window. A ScriptCard script is composed of an API command: !scriptcard {{ }} enclosing any number of lines that determine what actions the script will take and the output that will be added to the card. At it simplest, the following macro:
!scriptcard {{ }}
Will produce just a title card that displays “ScriptCards” as the name:
Of course, this is just the bare essential macro and isn’t very useful. In order to produce output that is helpful for playing a Roll20 game, we need to include lines between the {{ and }} that direct the API script as to what it should do.
Structure of a ScriptCard Line
All ScriptCard lines begin with two dashes, followed by an statement identifier character that lets ScriptCards what type of line it is. There are many different types of statements, and the bulk if this Wiki entry is dedicated to covering the use and function of each one.
After the line type identifier, a Tag name is supplied. This name is essentially free-form and CAN be omitted in the case of some line types. Also note that if you are used to using PowerCards, Tags in ScriptCards do not need to be unique.
Following the Tag is a vertical bar, and then the content of the line itself. Again, each type of line might interpret this content differently.
Example:
--#title|Longsword Attack
In this example:
- # is the statement identifier character, indicating that this line will be a "settings" statement.
- title is the Tag name. For the "#" statement type, this indicates what setting we will be updating.
- | separates the Tag from the Content
- Longsword Attack is the Content portion of the statement. In this case, it indicates what will be placed in the "title" setting.
Statment Types Quickreference
The table below lists each of the statement identifier types available in the ScriptCards language. Each entry also lists what the Tag is used for (if at all) and the format the Content is expected to be in along with usage notes.
Identifier Statement Type Tag Content Notes --/ Comment unused unused The --/sequence is used to add comments to a script. No processing will take place on a --/ line, so the tag and comment can be freely used to add notes to your code.--# Set Parameter Parameter name Desired parameter value Parameters generally control the behavior of large segments of the output card. Things like the Title of the card, the colors of the header and rows, etc. There are also parameters that control how various features of the card behave (like "usehollowdice"). --+ Direct Output Free Text - Is output in bold at start of the line. Output in normal text after Tag Direct Output statements are what creates row sections on the output card. A script without any direct output sections will end up looking similar to the sample at the start of this wiki (the !script {{ }} script) because all other statement types do not create output lines. --= Assign Roll Variable Variable Name Roll Equation (or text) to assign Roll/Numeric variables are assigned with this command. The content will be processed as a dice roll, and various properties will be set along with the numeric results. --& Assign String Variable Variable name Content to store in the string variable. Roll Variables and String Variables are completely separate entities, and can technically share names, but this would likely lead to confusion and should be avoided. --@ API Call API ! Command API call parameters (replace -- with _) Other Roll20 API scripts can be called using this command. The Tag is the trigger command for the API script (i.e., !token-mod, or !setattr, etc.) --: Branch Label Label Name Unused (Comments if desired) Branch labels are the destination for branch and procedure call statement types. The content portion of the statement is unused, though it is recommended to list parameter information here if you are writing a procedure that accepts passed parameters --^ Branch To Label name to branch to Unused (Comments if desired) An unconditional branch to a label (--:). Execution of the script will jump to the line after the named label. --> Call Procedure Label name to call Procedure parameter list semicolon (;) separated An unconditional procedure call. Execution will jump to the line after the named label, and a return statement (--<) will return execution to the line after the procedure call --< Return from Sub Unused Unused (Comments if desired) The return statement returns execution to the most recent procedure call line. Note that the vertical bar is required for the statement to be complete. --? Conditional Branch Condition to be evaluated True Branch Label|False Branch Label The condition will be evaluated and execution will jump to one of the two indicated branches (or simply continue to the next line if only a True branch is specified and the result is False). You can make the branch a procedure call by prefixing the label with a > symbol. In this case, you can included a semicolon separated list of parameters. --s Store to Persistent Storage "settings", "rollvariables", or "stringvariables" Name of the data set to store (see save/load section below) This statement type (and the --l statement) still function, but it is recommended to use the storage mechanism in the --~ command instead. --l Load from Persistent Storage "settings", "rollvariables", or "stringvariables" Name of the data set to store (see save/load section below) This statement type (and the --s statement) still function, but it is recommended to use the storage mechanism in the --~ command instead. --v Create Visual Effect "token", "betweentokens", or "point" Tokens and parameters for generating the effect Visual effects are played on the page the token is on. "point" effects require Version 1.2.8+ --a Play Audio Track Unused Jukebox track name (case sensitive) Plays an audio track by name from the Roll20 jukebox. Requires v1.5.2+ --e Echo to Chat Name to send chat command as Chat message to send Variable substitution takes place on the tag and content. --R Retrieve Repeating Section Row information "find", "first", or "next" Parameters for retrieving row information. See Referencing below Working with repeating section information on character sheets is possible without tracking row indexes ($0, $1, etc.) by using the --R statements. --~ Assign a variable to the result of a built-in function Variable Name Parameters for function call ScriptCards includes a number of built-in functions for things like measuring distance, manipulating strings, etc. The type of variable that gets set (Roll or String) is dependent upon the function that is being called. --c Case Statement Test Value Vertical bar separated list of cases, with the match:branchlabel format. Branch labels can be procedure calls by prefixing them with ">", and can contain parameters. --i Information Request User Prompt;Button Caption InfoType;VariableName;ParameterText See full documentation below. --d Data Statement ! for data definition or StringVar for data read For definition lines, a semicolon separated list of data elements. Unused to read lines. Similar to BASIC read/data statements. --d! defines string data elements anywhere in your code. --dvarName reads the next data element into varName. --% For...Next Loop Loop Counter for "For", empty for "Next" For "For", Start;End;Step, empty for Next See For...Next Loop documentation below. Allows you to create loops that will run a specified number of times with a loop counter. --* GM Output Free Text - Is output in bold at start of the line. Output in normal text after Tag GM Output statements are whispered to the GM as a separate card after the output of the main card is completed. Their use is identical to the Direct Output statement (--+). If there are no GM Output statements in a card, no GM card will be whispered. --! Object Modification <objectType>:<objectId> setting:value|setting:value... Set properties of tokens/characters or character attributes (v1.5.0+ required)
ScriptCard Statement Type Details
The sections below detail the individual statement types supported by ScriptCards
Comment (--/)
A --/ statement is ignored by the ScriptCards parser. You can use this type of statement to add comments and informational text to your script.
Example:
!script {{
--/|Script Name : Fireball
--/|Purpose : Allow the player to cast a fireball and blow stuff up!
.
.
.
}}
Set Parameter (--#)
A --# statement sets parameters used by ScriptCards when the card output is built. These include things like the title of the card, the background colors used for various portions of the card, the content of the left and right subtitle blocks, the tokens displayed in the emote (if any), the emote text, etc. A full list of these setting values is included below.
For settings statements, the Tag determines the setting that will be updated, while the Content determines the value that will be stored in that setting.
For global settings, if the same setting is set multiple times in a script, the MOST RECENTLY EXECUTED setting will be what is used when the card output is built. Most settings are "Per-Line", meaning they will only impact output lines generated after the setting is made, and can thus be changed with every line if desired.
Examples:
--#title|Magic Missile --#leftsub|Level 1 Spell --#rightsub|Force Damage
The three examples above set the “title”, “leftsub”, and “rightsub” values for the card to the content value for the line.
Content portions can include roll variables (see --= lines below) and can be used multiple times in a macro. The last execution of a setting line will be the one used when the card output is generated. Settings Lines do not produce output lines on the card.
The following settings are available (note that parameter names are not case sensitive):
Name Effect/Use Default Value Type activepage If set to a page ID, will be used for [*P:] attribute references.

As of ScriptCards 1.6.0, ten user settings (usersetting0 thru usersetting9) are now available. These settings are not used by ScriptCards but are available for script author use. These settings are stored with setting set (--Ssettings and --Lsettings).
Setting Lines do not produce output lines on the card
Direct Output (--+)
A direct output line display a line of content on the ScriptCard. It can be a simple line of text with a Tag/Content pair, or it can include Roll Variable references and inline formatting. The Tag can be blank (the | is still required). If a tag is specified, it is output in bold at the beginning of the line followed by the content.
Examples of Direct Output lines:
--+Hello|World
--+Attack|The monster rolls [$Attack] to hit!
--+Damage|@{target|token_name} is hit for [$Damage] [#3333AA][b]frost[/b][/#] damage.
Direct Output lines support inline formatting, roll variable replacement, character attribute references, and procedure variables.
GM Output (--*)
A GM Output line is identical to a direct output line except that it will be sent on a separate card that is only visible to GMs.
Example:
--+PlayerLine|This line is shown on the public card --*GMLine|This line will only be shown to GMs, on a separate card.
Roll Variable Assignment (--=)
In ScriptCards, when you want to roll dice you need to store the result of the roll into a Roll Variable. This is done by specifying the name of the Roll Variable as the Tag, and the roll text as the Content of the line.
All components of a roll equation should be separated with spaces.
Examples:
--=MissileDamage|1d4 + 1
--=Attack|1d20 + @{selected|strength_mod} [STR] + @{selected|pb} [PROF]
In these examples, the MissileDamage Roll Variable will be set to the result of rolling 1d4 and adding 1. The Attack Roll Variable will roll 1d20, add the selected character’s strength modifier and proficiency bonus (assuming D&D 5E) and store that value into the variable. Text enclosed in square brackets ([]) is considered "flavor text" and will be added to the result text but does not impact the roll result.
The following dice formats are supported:
Format Pattern Example Description XdY 3d8 Simple format. Roll a Y-sided die X times XdYkhZ 2d20kh1 Roll Y-sided die X times and keep the highest Z number of dice XdYklZ 4d6kl3 Roll Y-sided die X times and keep the lowest Z number of dice XdY>Z 5d6>3 Roll Y-sided die X times and count a 1 for each roll greater than Z XdY<Z 5d6<3 Roll Y-sided die X times and count a 1 for each roll less than Z XdYr<Q and XdYr>Q 10d6r<2 Roll a Y-sided die X times, rerolling results less than or equal (or greater than or equal to) to Q XdYro<Q and XdYro>Q 10d6ro<2 Roll a Y-sided die X times, rerolling results less than or equal (or greater than or equal to) to Q one time, keeping the reroll result XdY! and XdY!>Q and XdY!<Q 8d6! Roll a Y-sided die X times, rerolling max results and adding them to the total for the die (or rerolling results >= or <= Q and adding (Exploding dice) XdYkhZr<Q and XdYkhZr>Q 4d6kh3r<1 Roll a Y-sided die X times, rerolling results less than or equal to (or greater than or equal to) Q, and keep the highest Z results XdY!h and XdY!l 4d6!h Roll 1dY X times. If the max number on the dice is rolled, roll it again and add to that die's total. Return only the highest (h) or lowest (l) die roll (Deadlands skill checks). XdF 4dF Fudge dice support. Roll a Fudge die X times, with possible values of +, -, or blank. Roll hover text and .Text will display the values appropriately. XdYW, XdYWS, XdYWH, XdYWSH 4d6W Wild dice support (as seen in games like d6 system). X-1 dice of Y sides will be rolled normally. 1 die of Y sides will be rolled as an exploding die. If the "S" modifier is specified, the Wild die will eliminate itself from the total if the first roll on it is a 1. If the H modifier is included, a 1 on the initial Wild die will remove the highest die amongst the non-wild dice. None, one, or both can be specified. (v1.5.1)
The following operators are supported in a roll equation:
Operator Operation + Addition - Subtraction * Multiplication / Division \ Integer Division (Rounds down) % Modulo (Remainder of Divison)
Roll Variables can be accessed at any time after they have been created by using the [$VariableName] format, with the following optional modifiers:
Modifier Meaning No modifier In a Direct Output Line (--+) will be replaced with a formatted roll display, including a mouseover with roll text details. In any other type of line, will display the same results as .Total .Total The end result of the roll equation as an unformatted number .Base The cumulative result of any dice rolled in the Roll Text (Numeric modifiers are not included) .Ones The number of dice in the roll that came up as 1s .Aces The number of dice in the roll that came up as the maximum number on the die .Odds The number of dice in the roll that came up with an odd number .Evens The number of dice in the roll that came up with an even number .RollText The raw text of the roll that was use to generate the results .Text A text representation of the results of the roll, including the numbers rolled for each die .tableEntryText The text portion of the result of a table roll .tableEntryImgURL The image source portion of the result of a table roll .tableEntryValue Numeric value of tableEntryText (via parseInt). If a non-numeric value, will be 0 .Raw The total numeric result without any formatting, even if placed somewhere formatting would normally be done.
Examples:
--+Total Damage|[$MissileDamage.Total] (roll was 1d4+1)
--+Base Damage|[$MissileDamage.Base] (without the +1)
--=Attack|1d20 + @{selected|strength_mod} [STR] + @{selected|pb} [PROF] + [$BlessBonus] [Bless]
In this case, 1d4 will be rolled and stored in “BlessBonus”, which can then be used in the Attack line.
Mathematical Functions in Roll Expressions
The ScriptCards roll parser works from left to right, always maintaining a current value and applying whatever comes next to the total. The functions here below can be added to a roll expression:
Expression Meaning {ABS} Absolute Value {CEIL} Ceiling value (round up to the next whole number) {FLOOR} Floor value (round down to the next whole number) {ROUND} Round value (round up if the decimal portion is greater than 0.5, otherwise round down) Note: As of 1.4.11, ROUND now supports :X as a suffix to round to a given number of decimal places (ie, {ROUND:2} {NEGATE} Multiply the value by negative one. {SQRT} Take the square root of the running value. {SQUARE} Square the running value. {CUBEROOT} Take the cube root of the running value. {CUBE} Cube the running value. {SIN} Return the SIN of running value. {COS} Return the COS of running value. {TAN} Return the TAN of running value. {ASIN} Return the ASIN of running value. {ACOS} Return the ACOS of running value. {ATAN} Return the ATAN of running value. {MAX:X} Caps the running value at X. (v1.4.12) {MIN:X} If the running value is less than X, set the value to X. (v1.4.12) {CLAMP:X:Y} Adjust the running value to remain between X (lower bound) and Y (upper bound) (v1.4.12)
Here are the syntax rules when using the above listed functions:
Example 1.
!script {{
--=output|2.9 {FLOOR}
--+output|[$output]
}}
The output from this example is "2".
Example 2.
!script {{
--=output|2.9 {FLOOR} {NEGATE} - 3
--+output|[$output]
}}
The output from this example is "-5".
Basically, a function will use as its input whatever the current "running total" is.
Please note that there must always be a space between the function expression and its input. For example, "2.9 {FLOOR}" will work, but "2.9{FLOOR}" will not work.
Special Notes about Dice Rolls (READ THIS!): In order to support the ability to include Roll Variable values in rolls, ScriptCards does not use the built-in Roll20 dice rolling engine, and does not support “inline rolls” (rolls included with [[ ]] in the card). Because I have included my own roll parser, there may be some odd roll methods that are not currently implemented. If you run into dice roll options that don’t work, please let me know and I’ll try to support them.
Special Notes Update: As of version 1.2.3, inline rolls will be parsed by ScriptCards, using only the FINAL RESULT of the roll. The components (dice, modifiers, etc.) will not be visible to ScriptCards.
Rolling on Rollable Tables You can also roll on a rollable table using the expression [T#tablename], where tablename is the case-sensitive name of the table in your game. Proper weighting for each entry in the table is taken into account when rolling on rollable tables. The .tableEntryText and .tableEntryImgURL properties of the Roll Variable will be set to the matching values on the resultant table entry.
Roll Variable Lines do not produce output lines on the card.
String Variable Assignment (--&)
String variables function in most ways like roll variables, except that they do not attempt to process any dice rolls, and do not have the list of properties that a roll variable has. They are designed to simply contain text. To assign a string variable, use the --& statement:
--&MyText|Hello
Here, we assign the text "Hello" to the string variable named MyText. You can also append text to a string variable by prefixing the content with a + sign:
--&MyText|+ World
If run after the statement above, MyText will now contain "Hello World".
String variables can be referenced using the syntax [&variablename]
Call API (--@)
ScriptCards can use a Call API instruction to execute other API commands. The Tag contains the API command to use (alter, or roll20AM, for example - do not include the !) The content portion of the statement contains the parameters that are passed to the API script. Because the -- sequence can't be used here, an underscore (_) at the beginning of the line or preceded by a space is replaced with -- before the API command is executed.
Examples:
--@eh|list
--@alter|_target|@{target|token_id} _bar|3 _amount|-[$Damage]
In the first example above, the command !eh list will be executed, calling EncounterHelper. In the second, AlterBars(Forum) is called to modify a token's Bar 3 value.
Note: When ScriptCards (or any API script) runs other API script commands, there is not an associated player attached to the executed command. This means that the script being called won't know if the person running the ScriptCard is, for example, a GM. The most common instance of this is when calling !token-mod and trying to use --ids instead of acting on selected tokens. Since this is an ability normally limited to GMs, you need to enable "Players can IDs" (in !token-mod config).
See API:Script Index for more options.
Branch Label (--:)
A branch label defines a line in your code that can be reached by one of the branching instructions (--^, -->, or --?). The Tag serves as the label name, and must be unique on the card.
The vertical bar (|) separator must be present, but the content portion of the line is unused and can be treated as a comment.
Examples:
--:MyLoop| --:CriticalHit|Will jump here if we roll a critical hit!
A Branch Label line does not produce an output line on the card.
Branch (--^)
A Branch line jumps execution to the label indicated by the Tag. The vertical bar (|) separator must be present, but the content portion of the line is unused and can be treated as a comment.
Examples:
--^MyLoop|Jumps to MyLoop --^SkipCrit|We didn't crit, so skip the Crit code
A Branch line does not produce an output line on the card.
Call Procedure (-->)
Similar to a branch, a Call Procedure (sometimes knows as a "gosub") line branches execution to the label indicated by the Tag. However, the return pointer of the call will be pushed onto a stack so that a Return instruction (--<) will return execution to the next line in the card. A list of parameters for the subroutine can be passed as the content portion of the tag, and are separated by semicolons (;).
Examples:
-->FixFormat|#3333FF;#999999
In this example, a label called "FixFormat" will be branched to as a subroutine, passing the parameters "#3333FF" and "#999999". In the subroutine, these parameters are referenced by number as [%1%] and [%2%].
Return (--<)
A return instruction marks the end of a Gosub procedure. Execution will return to the statement after the one that called the subroutine. The Tag and Content portions are both optional, but the vertical bar separator must be included.
Examples:
--<| --<|End of MySub
In both cases, the value of the tag and the content portions of the statement are ignored, but the vertical bar separator must still be present.
Conditional Statement (--?)
A conditional statement contains some equation in the Tag that will be evaluated. If any part of the comparison can/does contain a space, it needs to be surrounded by double quotes
Based on the true/false result of the evaluation, one of two execution paths will be taken. These execution paths are detailed in the content section of the statement. The "if true" path is specified first (directly after the vertical bar), and the "if false" path is specified after it, also separated by a vertical bar.
Example:
--?[$AttackRoll.Total] -ge [$TargetAC]|Hit|Miss
Prior to version 1.2.1, all conditional statements resulted in either a branch to a label statement, or a gosub branch. As of version 1.2.1 additional options for what happens when a condition is matched were added, and 1.2.5 adds further additional functionality.
Branch Format Meaning Label If just a label is specified, execution will branch to that label when the comparison is matched. >Label If a label name is preceded by a ">" character, a gosub branch will be performed. In this case, parameters can be passed to the subroutine by separating them from the label and each other with semicolons (;). Parameters that can contain a semicolon (like token/character IDs) should be surrounded by double quotes =VariableName The roll variable "VariableName" will be assigned the value following a semicolon (for example, the code "=Roll;1d20" will assign the value "1d20" to a variable named "Roll", if the condition is true). &VariableName The string variable "VariableName" will be assigned the value following a semicolon (for example, the code "=Result;Hit" will assign the value "Hit" to a variable named "Result", if the condition is true). % or %! The current for...next loop will perform the "next" action (%) or will break out (%!) [ Code block (see below)
Examples:
--?[$AttackRoll.Base] -eq 20|CriticalHit
--?[$AttackRoll.Base] -eq 1|>Fumble;@{selected|dexterity_mod}
--?"@{target|npc_type}" -inc "undead"|&MonsterType;Undead|&MonsterType;Not Undead
--?[$Attack.Total] >= [$ArmorClass]|>Hit|>Miss
In the first example, if the Base value of AttackRoll is a 20 (natural 20 on the die) execution will branch to the CriticalHit label.
In the second example, if the Base value of the AttackRoll is 1 a gosub branch will be executed to the "Fumble" label, and passed the value of the selected character's dexterity_mod as parameter [%1%].
The third example looks for the word "undead" in the npc_type attribute of the targeted character. If it exists in the text, the MonsterType string variable will be set to "Undead", otherwise it will be set to "Not Undead".
The final example would call the "Hit" procedure on a hit and the "Miss" procedure on a miss and return execution to the next line after the procedure calls were finished.
Text that does/may contain a space should be enclosed in double quotes.
The following comparison operators are available:
Comparator Meaning -eq Equal To -eqi Case insensitive Equal To -ne Not Equal To -nei Case insensitive Not Equal To -gt Greater Than -ge Greater Than or Equal To -lt Less Than -le Less Than or Equal To -inc Includes (text strings). -ninc Does Not Include (text strings).
Multi-part conditionals are supported with -and and -or as separators. For example:
--?[$Attack.Total] -ge @{target|npc_ac} -and [$Attack.Base] -ne 20|HitButNotCrit
Multi-part conditionals are evaluated from left to right, and each evaluation is either ANDed or ORed with the current cumulative state. This means that (assuming "true" and "false" are actually conditional expressions that evaluate to either true or false):
true AND false OR true
Will be evaluated as true. The first two (true and false) will be false, but then false OR true will be true.
Conversely:
true or false and false
Will be false, because the first true and false will evaluate to true, and then true and false will be false.
CODE BLOCKS
A new feature (1.2.7), code block allow you to treat a group of statements as a single unit based on a condition. This is similar to begin...end or curly braces in some languages, though a bit more limited. As part of the true or false execution branch of a conditional, you can use the "[" character to begin a code block.
If that execution path is taken, the code in the block will be executed. Otherwise, the code in the block will be skipped. Blocks are completed with the --]| statement, and can optionally include an "else" block by using --]|[ as the block terminator. Here is an example:
!script {{
--=Roll|1d2
--+Roll|[$Roll]
--?[$Roll.Total] -eq 2|[
--&Value|Yep!
--+|We are inside the TRUE portion of the block
--]|[
--&Value|Nope
--+|We are inside the FALSE portion of the block
--]|
--+After|the blocks!
--+Value|[&Value]
}}
In this case, we begin by rolling 1d2 and then use a conditional to see if the result is 2. if it is, we execute everything inside the code block that begins on the conditional line, up until the end of the block marked with --]|[ because we have an "else" block. The else block is terminated with --]|.
At this time, blocks cannot be nested, and can only be created as part of a conditional (--[ is not a valid statement type)
A conditional statement does not produce a line of output on the card.
Case Statement (--c)
The case statement (--c) allows you to specify a value to test as the tag and a list of possible matches. These matches are case-insensitive. Matching groups are separated with vertical bars and matches and their branch labels are separated by a colon (:). It is also allowable to use Roll Variable or String Variable assignment syntax instead of a branch label, just as with the --? statement. If none of the values are matches, the script will simply proceed onto the next line. Both direct and procedure branches are supported, and procedure branches can include parameters as normal. Example:
!script {{
--#title|Case Statement Testing
--=Roll|1d4
--C[$Roll.Total]|1:>One;[$Roll]|2:>Two;[$Roll]|3:>Three;[$Roll]|4:>Four;[$Roll]
--X|
--:One| --+Value|was One ([%1%]) --<|
--:Two| --+Value|was Two ([%1%]) --<|
--:Three| --+Value|was Three ([%1%]) --<|
--:Four| --+Value|was Four ([%1%]) --<|
}}
This script uses the value of [$Roll.Total] and compares it against 1, 2, 3, and 4, using a gosub branch to the matching value. The first match test is “1:>One;[$Roll]”, where “1” is the value being matched, followed by a procedure branch to “One” which gets the roll variable as a parameter.
As a further example, the case statement below uses the value of a roll query to assign a Roll Variable based on the query result:
--c?{Difficulty|10|20|30|40}|10:=BonusHealing;0|20:=BonusHealing;10|30:=BonusHealing;30|40:=BonusHealing;50
The $BonusHealing variable will then contain either 0, 10, 30, or 50 depending upon the user's choice.
Using this syntax, the first example in this section could be rewritten as:
!script {{
--#title|Case Statement Testing
--=Roll|1d4
--C[$Roll.Total]|1:&Result;One|2:&Result;Two|3:&Result;Three|4:&Result;Four
--+Value|was [&Result] ([$Roll.Raw])
}}
Instead of branching, this example assigns the string variable &Result to "One", "Two", "Three", or "Four" depending on the output of the roll and displays it along with the $Roll itself.
Save and Load (--s and --l)
This statement pair is used to either store (--s) or load (--l) data from persistent storage. Items stored in persistent storage remain between card rolls and between Roll20 sessions. There are two types of data that can be stored: settings and roll variables.
Examples:
--Ssettings|GreenStyle --Srollvariables|FirstCardVars
In this case, the tag for the statement determines what type of item is being saved (settings or rollvariables). When saving settings, all non-default settings are written to the named setting storage value. When Roll Variables are saved, all variables that currently exist will be saved to the named storage value.
Loading stored items simply requires the same command with the --l statement type:
--Lsettings|GreenStyle --Lrollvariables|FirstCardVars
When loading settings, all stored settings will be applied to the current card settings. You can override settings by changing them after the load.
When loading roll variables, the saved variables will be added to (or overwrite if they have the same name) any variables on the current card. This means it is safe to create roll variables before the load statement.
Practical Uses The major intended use of persistent storage is for storing card formats for use in later scripts. For example, the following script:
!scriptcard {{
--#titlecardbackground|#22CC22
--#oddrowbackground|#cceecc
--#evenrowbackground|#99ee99
--Ssettings|@{selected|token_name}
}}
Would save the titlecardbackground, oddrowbackground, and evenrowbackground settings to a saved list named after the selected token's name. When creating cards for that token to run later, you could include the line:
--Lsettings|@{selected|token_name}
To load all of the settings at once. By creating these setting sets for each character, you can specify a different color scheme for each character that can then be used in cards with a single formatting line.
There is a supplemental ! command added to support saved settings:
!sc-liststoredsettings
Will produce a list of all stored setting names, with buttons to list the setting values stored in each group and a button to delete groups as needed.
Visual Effects (--v)
The --v statement can be used to create visual effects on the tabletop. The tag portion of the statement can be either "token" or "betweentokens". The content portion of the statement contains the required parameters for the effect generation, separated by spaces. If the effect is "none", no effect will be played. If any other value that doesn't match a Roll20 effect name will result in a burst-fire effect.
For "token" effects, the parameters are the token id for the token the effect happens on, followed by the effect specifier.
Example:
--vtoken|@{selected|token_id} burst-fire
For "betweentoken" effects, the parameters are the source token id, the target token id, and the effect specifier.
Example:
--vbetweentokens|@{selected|token_id} @{target|token_id} beam-magic
Version 1.2.8+
An additional effect specifier, "point" is available in 1.2.8+. This specifier allows you to create a visual effect at a designated X/Y pixel coordinate. Future updates will add custom-vfx support to this option. The parameters are the X and Y coordinates and the effect descriptor. As of version 1.2.9, you can also use custom effect specifiers with Point effects:
--vpoint|150 200 burst-fire
Audio Effects (--a)
Requires version 1.5.2+
The --a statement plays an audio track from your Roll20 jukebox by name. The content value of the statement specifies the case-sensitive name of the track to play. If the jukebox track does not exist, no sound will be played, and a warning will be output to the API console log indicating the missing track.
--a|SwordHitSound
No external APIs are required.
Echo to Chat (--e)
The echo statement is simply a call to the API's sendChat command, using the tag as the speakingAs parameter and the content as the text to send.
Example:
--eThe Ghost|/em hovers around @{selected|character_name}... BOO!
Would output "The Ghost hovers around (charactername)... BOO!" as an emote to chat. This will happen whether or not you have a character named "The Ghost" in your journal or not (roll20 sees this message as coming from the API, not from a player or a character).
Whispering
You can use the echo statement to send a whisper, but there's a trick to it. If you execute this code here:
--eThe Ghost|/w ExamplePlayerName Boo.
Then the player named "ExamplePlayerName" would see on his screen a whisper from "The Ghost" that says "Boo."... but you would not see anything on your screen! And you wont see anything on your screen no matter what you try to replace "The Ghost" with... not even if you try to use "GM" or your own player name. Because, again, roll20 sees the message as coming from the API, not from a player or a character.
So, in conclusion, it's best to use something like this when you're sending a whisper:
!script {{
--#hidecard|1
--&sender|The Ghost
--&receiver|ExamplePlayerName
--&message|Boo.
--e[&sender]|/w [&receiver] [&message]
--eScriptCards|/w gm **Whispered from [&sender] to [&receiver]:** [&message]
}}
This will ensure that the message appears in your chat feed as well.
Repeating Section Access (--R)
ScriptCards (as of v0.0.13) supports accessing repeating section rows on a character sheet (for example: the attacks, the items, and the repeating resources) with the --R statement type.
There are three basic commands you can use with --R, and they are specified by the tag used:
The "find" tag
An Rfind statement is used to search through a repeating field. Here is the general form of such a statement.
--Rfind|characterid;EntryName;SectionPrefix;SearchField
This is the most direct way to access a repeating section row. Supplying the character ID, followed by what you are looking for (Greatsword, for example), followed by the character sheet's section prefix (repeating_attack), followed by the field to check what you are searching for (atkname) will load the matching section (if found) into the script parsers memory. For example:
--Rfind|@{selected|character_id};Greatsword;repeating_attack;atkname
Will look at the character's "repeating_attack" section for an entry with an atkname value equal to "Greatsword". Similarly:
--Rfind|@{selected|character_id};Bite;repeating_npcaction;name
Will look for a "Bite" action on an NPC's action list.
The "first" tag
--Rfirst|characterid;section prefix
This form of the --R command will look at all of the entries in the specified repeating section and load the first one into memory:
--Rfirst|@{selected|character_id};repeating_attack
Would load the character's first "repeating_attack" row into memory.
The "next" tag
--Rnext|
No parameters are required for --Rnext, which loads the next entry in the list that was obtained with "first" into memory.
Section prefixes and how to use them
To see the complete list of the section prefixes for the "D&D 5E by Roll20" character sheet, as well as a nice explanation for how to use them, please open this page, and search for the phrase "repeating sections".
Additional information
However a row is obtained, it will be parsed to replace any attribute references (ie, @{level}) with the corresponding character attribute.
If at any point, a valid entry isn't found (find doesn't find something, first doesn't see any rows, or next goes off the end of the list) any attempts to reference the row data will return "NoRepeatingAttributeLoaded".
You can reference repeating attribute data using the syntax [*R:attributename] syntax (similar to referencing standard character attributes).
Here are some examples:
Display the details of the "Greatsword" PC attack:
!script {{
--Rfind|@{selected|character_id};Greatsword;repeating_attack;atkname
--+Attack Name|[*R:atkname]
--+Base Damage|[*R:dmgbase]
}}
List all of the actions an NPC can take (just actions, not legendary, etc.)
!script {{
--#title|NPC Actions
--#leftsub|@{selected|token_name}
--Rfirst|@{selected|character_id};repeating_npcaction
--:DisplayLoop|
--?"[*R:name]" -eq NoRepeatingAttributeLoaded|Done
--+Action:|[*R:name] [*R:attack_damage] [*R:attack_damagetype]
--?"[*R:attack_damage2]" -eq ""|NoSecondaryDamage
--+ |[*R:attack_damage2] [*R:attack_damagetype2]
--:NoSecondaryDamage|
--Rnext|
-->DisplayLoop|
--:Done|
}}
In the script above, we get the "first" repeating_npcaction and display information about it. We then execute "next" and repeat until we run into "NoRepeatingAttributeLoaded".
See the section named Repeating Section Values for more information.
Special debugging command: dump
--Rdump|
The "dump" command will list all of the attributes ScriptCards knows about for the currently loaded repeating row to the API Console Log.
Assign Variable to Built-In Function (--~)
ScriptCards has the ability to run a function built into the API script and return the results to a variable. Some functions return roll variables, while others return strings. See the function table below for details. The format is:
--~VariableName|function;param1;param2;param3;...
Function Name Parameters Description distance token_A_ID;token_B_ID Calculate the Chebyshev distance in grid units between two tokens. This is the measurement scheme D&D 4E/5E use for diagonal distance measurement euclideandistance token_A_ID;token_B_ID Calculate the Euclidean distance between two tokens. This is essentially the Pythagorean theorem in action. Returns the result in grid units. euclideanpixel token_A_ID;token_B_ID Calculate the Euclidean distance between two tokens and returns the result is pixels instead of grid units. euclideanlong token_A_ID;token_B_ID Calculate the Euclidean distance between two tokens and returns the result in grid units, but the grid unit conversion is performed AFTER the pixel distance is calculated instead of before. More accurate over long distances. manhattandistance token_A_ID;token_B_ID Also called "taxicabdistance" (which is an acceptable function name), this measures to how-many-over, how-many-up/down distance, disallowing diagonal movement. getselected none Using the variable name in the tag, a series of string variables will be created: VariableNameCount will contain the number of selected tokens. VariableName1 will contain the token ID of the first selected token, VariableName2 the second, etc.
Functions with Sub Functions
Most ScriptCards functions are grouped into set as sub functions. The table below lists the major functions and their sub functions.
Function Name Sub Function Parameters Return Type Description array define arrayname;value1;value2;... none Creates an array called "arrayname" and adds value1, value2, etc. to the array array sort arrayname none Sorts the specified array in place in ascending order (alphabetically) array numericsort arrayname none Sorts the specified array in place in ascending order (numerically) (v 1.4.10+ ) array add arrayname;value1;value2;... none Adds value1, value2, ... to the existing array "arrayname" array remove arrayname;value1;value2;... none Removes value1, value2, ... from the existing array "arrayname".

Will return "ArrayError" if the end of the array is reached. array getprevious arrayname stringVariable Decrements the current index in "arrayname" and returns the new current value. Will return "ArrayError" if the the current index was already zero. array getfirst arrayname stringVariable Set the current index of "arrayname" to zero and retrieve the current item. Will return "ArrayError" if there is no current item. array getlast arrayname stringVariable Set the current index of "arrayname" to the last item in the array and retrieve the current item. Will return "ArrayError" if there is no current item. array removeat arrayname;indexposition none Removes the item at index "indexposition" from "arrayname". Resets the current array index to 0. array indexof arrayname;searchvalue stringVariable Searches the array "arrayname" for and item with the value of "searchvalue" and, if found, returns the index of the first matching value or "ArrayError" if not found array getlength arrayname stringVariable Returns the number of items in array "arrayname" array pagetokens arrayname;tokenid;(optional filter) stringVariable Creates an array (arrayname) of all of the token ids (technically Graphics objects) on the same page as the specified token id. Returns the number of tokens found to the stringVariable. Available optional filters are : all, char, graphic, pc, npc. The filters will return only those tokens that match that criteria (char means tokens have a "represents", graphic doesn't. pc indicates a represents token has a controlledby, npc doesn't.) array selectedtokens arrayname stringVariable Creates an array (arrayname) of all of the token ids (technically Graphics objects) selected when the script was executed. Returns the number of tokens found to the stringVariable. array stringify arrayname stringVariable Returns all of the items in "arrayname" as a string separated by semicolons (;) array fromstring arrayname delimiter;string Creates an array from "string", splitting "string" on "delimiter" to separate the items array statusmarkers arrayname;tokenid none Creates an array (arrayname) of the active statusmarkers (sometimes called Token Markers) for the specified tokenid math angle math;angle;tokenid;tokenid rollVariable Calculates the angle between two tokens and returns the value in degrees math ceil math;ceil;value rollVariable Rounds value up to the next integer, dropping any decimal portion of the number math clamp math;clamp;value;lowerBound;upperBound rollVariable Returns value, but restricted to the range of lowerBound and upperBound. math floor math;floor;value rollVariable Rounds value down, dropping any decimal portion of the number math max math;max;valueA;valueB rollVariable Returns the larger of valueA vs valueB math min math;min;valueA;valueB rollVariable Returns the smaller of valueA vs valueB math round math;round;value rollVariable Rounds value to the nearest integer string length string;length;stringValue rollVariable Returns the length of stringValue in characters string before string;before;searchText;stringValue stringVariable Searches stringValue for searchText and returns the portion of stringValue prior to that text string after string;after;searchText;stringValue stringVariable Searches stringValue for searchText and returns the portion of stringValue after that text string left string;left;count;stringValue stringVariable Returns the leftmost count characters of stringValue string right string;right;count;stringValue stringVariable Returns the rightmost count characters of stringValue string replace string;replace;searchText;replaceText;stringValue stringVariable Replaces searchText in stringValue with replaceText and returns the resulting string string replaceall string;replace;searchText;replaceText;stringValue stringVariable Replaces all intances of searchText in stringValue with replaceText and returns the resulting string Requires 1.2.9+ string trim string;trim;stringValue stringVariable Removes leading and trailing spaces from stringValue and returns the result. string substring string;substring;start;count;stringValue stringVariable Returns count characters starting at start from stringValue string split string;split;delimiter;stringValue special Splits stringValue into pieces, breaking it at delimiter. Returns a rollVariable with "Count" appended to the assigned variable name and a series of string variables with numbers appended (starting at 1) for each of the returned pieces. string tolowercase string;tolowercase;stringValue stringVariable Converts the passed string to lower case and assigns to the passed variable name. string touppercase string stringVariable Converts the passed string to upper case and assigns to the passed variable name. string totitlecase string stringVariable Converts the passed string to title case (capitlaizes the first letter of each word) and assigns to the passed variable name. stateitem write stateitem;write;variableType None Writes the variable specified in the tag to persistent storage. Specify either rollvariable or stringvariable for variableType. One of each type can be stored in persistent storage at a time. stateitem read stateitem;read;variableType Depends on variableType Reads the stored variable of the specified type (either rollvariable or stringvariable) and stores the result in a variable named for the line tag. turnorder clear none none Clears all entries from the t Turn Tracker/Initiative turnorder addtoken tokenid;trackervalue none Adds the token represented by "tokenid" to the initiative tracker with an initiavie value of "trackervalue" turnorder replacetoken tokenid;trackervalue none Replaces the token represented by "tokenid" in the initiative tracker with an initiavie value of "trackervalue". Will add the token if it doesn't exist in the tracker. turnorder removetoken tokenid none Removes the token represented by "tokenid" from the initiative tracker if it exists turnorder addcustom textlabel;trackervalue none Add a custom text entry to the t Turn Tracker/Initiative named "textlabel" with an initiative value of "trackervalue" system date getdatetime stringVariable Returns the date time in the active timezone (see settings) system date getdate stringVariable Returns the date in the active timezone (see settings) system date gettime stringVariable Returns the time in the active timezone (see settings) system dumpvariables "rolls", "string", or "array" none Dumps all of the defined variables of the indicated type to the console log system findability system;findability;charactername;abilityname stringVariable Returns the object ID of the ability on the indicated character or "AbilityNotFound"
Examples:
--~HowFarAway|distance;@{selected|token_id};@{target|token_id}
Returns the distance (Chebyshev) between the selected and target tokens and stores it in "HowFarAway".
--SelectedDudes|getselected
If 5 tokens were selected, 6 variables would be created: SelectedDudesCount (with a value of 5), SelectedDudes1, SelectedDudes2, SelectedDudes3, SelectedDudes4, SelectedDudes5.
Information Request (--i)
An Information Request statement allows your script to pause and “ask” the user for additional input. The statement type is --i, and uses the Tag portion of the statement to define a prompt to the user and the caption of a button that will be displayed for the user to press to provide additional information. The content portion of the line is made up of a series of information request in the format “type;VariableName;PromptText”, with each request separate by double vertical bars.
ScriptCards will use the display text and the button caption to whisper the script sender a message with a button to click that can ask for information via roll queries or ask for targets to be selected. Multiples of each type and combinations are allowed. The result of each information request will be stored in a string variable matching the “VariableName” parameter for that request.
After the user has clicked the button and responded to the requests, ScriptCards will resume processing the script from where it left off.
Here is an example “i” line:
--IScriptCards needs additional information to continue;Click to select a target and provide information|t;MyNewTarget;Missile1Target||q;MyNameIs;What is your name?
The sample above will whisper the user "ScriptCards needs additional information to continue" and provide a button labeled "Click to select a target and provide information". When the user clicks the button, they will be requested to select a target labeled "Missile1Target" and a prompt will appear asking that they enter their name into a text field.
Supported information request types are “t” for target token, and “q” for query.
For “t” types, specify the variable name to store the token ID in as the second parameter and the prompt text that will appear in the “Choose Target” window (i.e. Choose Target: Missile1Target above).
For “q” types, specify the variable name to store the response in as the second parameter, and the text of the roll query without the ?{} identifiers. You can specify values for dropdowns, etc. For example:
q;UserName;What is your name?|Fred|Bob|Sally|Nancy
Would have a dropdown menu with four choices.
Object Modification (--!)
Requires ScriptCards version 1.5.0+
Object modification support is now available in ScriptCards. As of 1.5.0, you can use the --! command to modify object properties in the game. This may help reduce the reliance on the --@ command to run other API commands to modify token/character values. The biggest benefit of this is that the changes happen as the script is processing, so the new values are available right away.
The format of the command is:
--!<objectType>:<objectId>|setting:value|setting:value|setting:value...
objectType can be one of "t" for token, "c" for character, or "a" for character attribute
objectId can be a token id or a character id (or "S"/"T" for the Source/Target token/char defined with --#sourcetoken and --#targettoken)
setting and value pairs can be chained in a single statement separated by | to impact more than one property/attribute with a single line
Values can be prefixed with += or -= to add/subtract from the current value (no bounds checking is done). Using [*X] notation, the updated values can be read immediately. Using += or -= on non-numeric data will simply result in a string append.
For "a" types, setting names can be prefixed with a ! to create the attribute if it doesn't exist (by default, it will not be created), and postfixed with ^ to set the max value instead of the current value.
Note that there are VERY few attributes associated with a character object, and there are likely few cases where you would want to set anything on the character object, but it is still possible.
Examples:
Set the value of bar1_value for the selected token to 5:
--!t:@{selected|token_id}|bar1_value:5
Add 1 to the bar3_value for the selected token:
--!t:@{selected|token_id}|bar3_value:+=1
Set bar2_value to 5 and bar2_max to 10 for the selected token
--!t:@{selected|token_id}|bar2_value:5|bar2_max:10
For the character the selected token represents, set "dndstyling" attribute on, set "size" to enormous, and set "attitude" to epic. The attitude attribute will be created if it doesn't exist on the character already. The same is not true for dndstyling and size:
--!a:@{selected|token_id}|dndstyling:on|size:enormous|!attitude:epic
Adds 50 to the npc_xp attribute for the character represented by the selected token, displaying the value before and after the update:
!script {{
--+XP|[*@{selected|token_id}:npc_xp]
--!a:@{selected|token_id}|npc_xp:+=50
--+XP|[*@{selected|token_id}:npc_xp]
}}
Note that asynchronous read/update fields (bio, notes, gmnotes) are not currently supported.
Inline Formatting
Inline formatting is processed on Direct Output lines only (--+ lines) and the following inline format markup is available:
Formatting Tags Description [b]..[/b] Bold the text between the markers [i]..[/i] Italicize the text between the markers [u]..[/u] Underline the text between the markers [s]..[/s] Strike-Thru the text between the markers [c]..[/c] Center alignment [l]..[/l] Left alignment [r]..[/r] Right alignment [j]..[/j] Full justification alignment [br] Line break (translates to
in html)[hr] or [hr #xxxxxx] Insert a horizontal rule. If a 3 or 6 digit (or named) color code is specified after the # the rule will be colorized [#xxx]..[/#] or [#xxxxxx]..[/#] Use a 3 or 6 digit hex code to colorize the text between the markers [img]..[/img] Insert an image. The full URL of the image goes between the markers. You can include HTML attributes to be applied to the img tag in the opening marker (ie, [img width=128 height=128])[button]caption::action[/button] Create a button with the label "caption" that performs the action defined by "action". By default, buttons will be colored according the the buttontextcolor and buttonbackground card settings. You can optionally color individual buttons by specifying a text color and a background color as part of the [button] command (ie, [button:#ffffff:#000000] will create a button with white text on a black background. In order to set a background color, the foreground color must be specified. [sheetbutton]caption::character::abilityname[/sheetbutton] Create a button that, when pressed, will run the "abilityname" macro on the "character" charactersheet. Useful for launching macros from a macro mule character sheet. By default, buttons will be colored according the the buttontextcolor and buttonbackground card settings. You can optionally color individual buttons by specifying a text color and a background color as part of the [sheetbutton] command (ie, [sheetbutton:#ffffff:#000000] will create a button with white text on a black background. In order to set a background color, the foreground color must be specified. [rbutton]Caption::ReentryLabel;Parameter[/rbutton] Create a reentrant button which, when clicked by the user, will resume script execution at "ReentryLabel", passing "Parameter" to the [&reentryval] string variable. By default, buttons will be colored according the the buttontextcolor and buttonbackground card settings. You can optionally color individual buttons by specifying a text color and a background color as part of the [rbutton] command (ie, [rbutton:#ffffff:#000000] will create a button with white text on a black background. In order to set a background color, the foreground color must be specified. [t] Converted to HTML table tag. Text after the "t" will be included inside the tag (width, border, etc) [/t] Converted to HTML close table tag. [tr] Converted to HTML table row tag.

Variables
ScriptCards supports two types of variables : Roll Variables and String Variables. Either type can be used in a conditional statement, or use to substitute their value into the tag or content portion of other statements. For both types of variables, variable names are case sensitive. While it is possible to assign both a string and a roll variable the same name, doing so will likely result in confusion when looking at the script later, so it is not recommended.
String Variables are assigned with the --& statement and are referenced using [&variableName] notation.
Roll Variables are assigned with the --= statement, and the assignment value is always processed by the ScriptCards Roll Processor (resolves dice rolls, etc.)
There are a handful of variables assigned automatically when a ScriptCard is executed. These are all string variables, and are:
Variable Value SendingPlayerID Contains the object ID of the player that sent the macro SendingPlayerName Contains the display name of the player SendingPlayerColor Contains the color code associated with the player SendingPlayerSpeakingAs The contents of the "Speaking As" dropdown window SendingPlayerIsGM Contains 1 if the player is a GM, and 0 if the player is NOT a GM
Arrays
Arrays are a special type of variable, and are managed by the function (--~ command). All of the array function commands follow the same pattern:
--~variableName|array;subcommand;arrayname;param1;param2;param3;...
Not all array commands return anything to "variableName". The function table above will specify the return type of the command if any.
There are a couple of different ways to create an array:
The define array subcommand creates (or recreates) an array and assigns it values - one for each included parameter after the array name. For example:
--~|array;define;Fruits;mango;peach;strawberry;apricot;banana;apple
will create an array called Fruits with 6 elements in the order listed in the command (mango, peach, etc.)
You can also use two other subcommands to create arrays based on tokens:
--~Count|array;pagetokens;Everybondy;@{selected|token_id}
and
--~Count|array;selectedtokens;Selected
In both cases, arrays of tokens will be created, and a string variable called "Count" will be set to the number of tokens in the array. The pagetokens command returns (by default) all of the tokens on the page that contains the token passed as the parameter after the array name. You can filter the tokens that "pagetokens" includes in the array by appending an optional parameter describing the type of token you are looking for:
--~Count|array;pagetokens;Everybondy;@{selected|token_id};npc
Will return only tokens on the page that represent characters that do not have a controlledby parameter set. The available options are "all" (default), "char", "graphic", "pc", and "npc".
The selectedtokens command returns an array with all of the tokens that were selected when the script was called.
You can also use an arbitrary string to create an array, specifying a delimiter with the fromstring command:
--&names|Fred --&names|+,Sally --&names|+,Ted --&names|+,Joyce --~|array;fromstring;,;[&names]
The above example builds a comma-separated string and then uses "fromstring" to create an array with 4 elements from it, specifying the comma as the delimiter.
Finally, you can use the statusmarkers command to create an array with one entry for each active status marker on a specified token:
--~|array;statusmarkers;Conditions;@{selected|token_id}
will create an array with one entry for each status active on the selected token. The array elements will be the internal name of the status (if you are using custom status marker packs, the names will be specified in the marker pack).
Traversing Arrays
Each array keeps track of an internal index position (starting at 0). Several commands let you manage this index:
- getindex returns the current index value
- setindex sets the index to the specified location in the array
- getlength returns the number of elements in the array
- indexof returns the index location of the specified element
Other commands let you retrieve values from the array:
- getfirst sets the index to 0 and returns the value at that position
- getnext advances the index by 1 and returns the new current value
- getprevious reduces the index by 1 and returns the new current value
- getlast sets the index to the last elements in the array and returns the new current value
If/when you hit the end of the array, you will get a return value of "ArrayError", which can be used to detect the end of the array when looping through by index. See Referencing Array Elements below for additional information.
Manipulating Array Elements
Several array commands deal with inserting, removing, and modifying elements:
- add works just like define, except that it takes an existing array and adds elements to it based on the passed parameters
- remove looks for items matching each passed parameter and removes them from the indicated array if they exist
- removeat allows you to specify an index location in the array and remove the element at that position
- replace searches an array for a value and replaces all occurrences of it with a new value (if found)
- sort sorts the elements in the array in ascending order
- strinfigy returns a string variable that includes each array element separated by semicolons (;)
Referencing Array Elements
You can either use the index (getfirst, getnext, etc.) to traverse an array and work with the values, or you can use (new in 1.3.1) direct array element referencing.
!script {{
--~dummy|array;pagetokens;myarray;@{selected|token_id}
--~count|array;getcount;myarray
--+Total:|There are [&count] graphical objects on the page
--~testvar|array;getfirst;myarray
--:loop|
--+Value|[*[&testvar]:character_name]
--~testvar|array;getnext;myarray
--?[&testvar] -ne ArrayError|loop
--+Loop1|Is Done!
}}
This example defines an array based on the tokens on the page and then loops through them, starting with a getfirst, displaying the character name, and using getnext until the result is "ArrayError", at which point the loop exits. Here is the same routine, except it uses a For...Next loop and direct array referencing:
!script {{
--~dummy|array;pagetokens;myarray;@{selected|token_id}
--~count|array;getcount;myarray
--+Total:|There are [&count] graphical objects on the page
--%loopCounter|1;[&count]
--+Value|[*[@myarray([&loopCounter])]:character_name]
--%|
--+Loop|Is Done!
}}
This line : --+Value|[*[@myarray([&loopCounter])]:character_name] uses [@arrayName(index)] format (inside a [*characterid:attribute] syntax) to perform the same task as running through the loop with the index.
(Note: Additional examples are on the way...)
For...Next Loops
For...Next loops in ScriptCards are supported with the with the --% statement type. A loop is defined by starting off with:
--%LoopCounter|<start>;<end>;[step]
The start and end values are required, while the step parameter is optional. If the step is omitted, it will be assumed to be 1. A string variable named after the line tag ("LoopCounter" in the case above) will be created and will hold the current iteration value for the loop. Here is a real example:
--%LoopCounter|1;10;1
This will begin a loop identified by "LoopCounter" that will start at 1, increasing by 1 each iteration (the step) until it has completed 10 executions.
The "next" statement is simply --%|, with no tag or parameters. This indicates to ScriptCards that it should increment the counter and go back to the beginning of the loop. Extending the example above:
!script {{
--%LoopCounter|1;10;1
--=Roll|1d20
--+Loop|Counter is [&LoopCounter], roll was [$Roll]
--%|
}}
The --%!| sequence will break out of the loop, no matter how many iterations are remaining.
The % and %! character sequences can also be used as part of a 1.2.1+ non-branching conditional to continue or break the loop:
--?"X[&RollInto]X" -eq "XX"|%
In this example, if the string variable RollInfo is empty, the loop will return to the top and continue with the next iteration, while:
--?"X[&RollInto]X" -eq "XX"|%!
Would cause the whole loop to end if the condition were true.
Referencing
Referencing Overview
Referencing allows you to substitute the values of variables, objects, attributes, settings, and the like someplace in a ScriptCards line. The table below gives an overview of the various referencing modes and what each one means. In general, references are enclosed in square brackets ([ and ]) and begin with a character indicating what kind of reference it is, followed by a descriptor that indicates where the value should come from.
Character Type Example Notes $ Roll Variable [$AttackRoll] Roll variables support a number of modifiers (ie, [$AttackRoll.Base]). See the Roll Variables section below for details & String Variable [&PlayerName] * Object Attributes [*S:character_name] See Attribute Referencing in the next table for details. % Subroutine Parameters [%1%] Only available when a subroutine is called with a --> or similar construct. Parameters are numbered beginning at 1. @ Array Elements [@Colors(5)] The name of the array follows the @ symbol. The index (zero-based) is in parenthesis after the name. ~ Card Settings [~title] Returns the value of the ScriptCards settings (set via --# lines)
Object Attribute Referencing
All object attribute referencing use the "*" prefix character, with the second (and sometimes third) character providing context).
Prefix Example Notes *S: [*S:character_name] Returns token or character attributes for the token/character specified for the sourcetoken setting. Token attributes are prefixed with "t-" (ex: [*S:t-bar3_value]). *T: [*T:character_name] Returns token or character attributes for the token/character specified for the targettoken setting. Token attributes are prefixed with "t-" (ex: [*T:t-bar3_value]). *id: [*-lkfne34mda4:character_name] when * is followed by an ID, the token/character will be queried for the attribute value requested. *C: [*C:playerpage] Returns campaign attributes. *P: [*P:showgrid] Returns page attributes. If an activepage setting has been set, the activepage will be referenced. If not, the current playerpage (where the ribbon is) for the campaign is referenced. *R: [*R:atkname] Used with --R (repeating section) commands to return the VALUE of the current repeating row item's attribute by name. *R> [*R>atkname] Used with --R (repeating section) commands to return the full attribute name for a repeating row attribute.
Nested References
Reference syntax can be nested, and will be resolved from inside to outside. For example, given a roll variable (MishapRoll) and a series of strings (Mishap1, Mishap2, Mishap3, Mishap4), the following reference will begin by substituting [$MishapRoll.Raw] for the roll's numeric value, and then replace the resulting MishapX string with its value:
[&Mishap[$MishapRoll.Raw]]
Roll Variables
Roll Variables can be referenced from the content portion of any line type, and from the tag portion of conditional statements. The referenced value is replaced when the line is executed.
There are several modifiers that can be used to reference parts of a roll:
Modifier Meaning No modifier In a Direct Output Line (--+), GM Output Line (--*), or String Assignement (--&), will be replaced with a formatted roll display, including a mouseover with roll text details. In any other type of line, will display the same results as .Raw .Total The end result of the roll equation. Formatting rules for "No Modifier" apply based on line type. .Raw The total value of the roll variable without any formatting, no matter what kind of line the reference is used in. .Base The cumulative result of any dice rolled in the Roll Text (Numeric modifiers are not included) .Ones The number of dice in the roll that came up as 1s .Aces The number of dice in the roll that came up as the maximum number on the die .Odds The number of dice in the roll that came up with an odd number .Evens The number of dice in the roll that came up with an even number .RollText The raw text of the roll that was use to generate the results .Text A text representation of the results of the roll, including the numbers rolled for each die .tableEntryText The text portion of the result of a table roll .tableEntryImgURL The image source portion of the result of a table roll .tableEntryValue If the tableEntryText is purely numeric, will contain the numeric value
String Variables
To reference a string variable, use the notation [&variablename]. String variables can be referenced in direct output, roll variable assignment, and string variable assignment statements.
Character/Token Attributes
A character or token attribute can be referenced from content portion of any type of line and is substituted when the line is executed. The general format for referencing a character attribute is [*ID:attribute]. ID can be a token ID or a character ID (these start with a dash). Additionally if you have specified a sourceToken or targetToken, you can substitute "S" or "T" for the ID (for example [*S:npc_type] will retrieve the npc_type attribute from the source token.
By default, all attribute references will be pulled from the character object that the ID represents (either directly or by being a Token ID that represents a character).
Keep in mind, that if you want to access the "max" of a character attribute (for example, the max hit points), then you cannot trust the name that your roll20 character sheet shows you when you hover your mouse over the max hit points. For example, this reference will not work: [*S:hp_max]. Instead, you need to use this reference: [*S:hp^].
If your ID refers to a token, token attributes can be accessed by preceding the attribute name with "t-", for example [*S:t-aura1_radius]. Supported token attributes are: (NOTE: As of version 1.6.1 of ScriptCards, the below list is no longer a limitation on the token attributes you can reference. All token attributes available in Roll20 can now be accessed and the need to update the internal list as new attributes are added has been eliminated.)
| t-name | t-id | t-statusmarkers | t-bar1_value |
| t-bar1_max | t-bar2_value | t-bar2_max | t-bar3_value |
| t-bar3_max | t-top | t-left | t-width |
| t-height | t-rotation | t-layer | t-aura1_radius |
| t-aura1_color | t-aura2_radius | t-aura2_color | t-aura1_square |
| t-aura2_square | t-tint_color | t-light_radius | t-light_dimradius |
| t-light_angle | t-light_losangle | t-light_multiplier | t-light_otherplayers |
| t-light_hassight | t-flipv | t-fliph | t-controlledby |
| t-_cardid | t-_pageid | t-imgsrc | t-bar1_link |
| t-bar2_link | t-bar3_link | t-represents | t-layer |
| t-isdrawing | t-name | t-gmnotes | t-showname |
| t-showplayers_name | t-showplayers_bar1 | t-showplayers_bar2 | t-showplayers_bar3 |
| t-showplayers_aura1 | t-showplayers_aura2 | t-playersedit_name | t-playersedit_bar1 |
| t-playersedit_bar2 | t-playersedit_bar3 | t-playersedit_aura1 | t-playersedit_aura2 |
| t-lastmove | t-adv_fow_view_distance | t-has_bright_light_vision | t-has_night_vision |
| t-night_vision_distance | t-emits_bright_light | t-bright_light_distance | t-emits_low_light |
| t-low_light_distance | t-has_limit_field_of_vision | t-limit_field_of_vision_center | t-limit_field_of_vision_total |
| t-has_limit_field_of_night_vision | t-limit_field_of_night_vision_center | t-limit_field_of_night_vision_total | t-has_directional_bright_light |
| t-directional_bright_light_center | t-directional_bright_light_total | t-has_directional_dim_light | t-directional_dim_light_center |
| t-directional_dim_light_total | t-lightColor | t-tooltip |
It is important to note that some attributes names on tokens have corresponding attribute names on characters, which represent different values. For example, [*T:id] returns the character ID, while [*T:t-id] returns the token ID.
Subroutine Parameters
When using a gosub statement (-->) or a conditional marked as a gosub (prefixing the label with a > character), you can pass any number of parameters separated by semicolons (;) that the code in the subroutine can utilize.
Subroutine parameters are numbered starting at 1, and are accessed by using the notation [%number%], so the first parameter is [%1%], the second is [%2%], etc.
Parameter substitution happens on all line types, and happens prior to character attribute references or roll variable substitution.
Campaign Attribute
You can retrieve properties of the API's Campaign object with the [*C:attributename] syntax. For example, [*C:playerpageid] will retrieve the current player ribbon page from the Campaign object.
Page Attributes
If you have set the activepage parameter, you can retrieve page-related properties with the [*P:attributename] syntax, including the page's UDL parameters.
Repeating Section Values
You can reference repeating attribute data using the syntax [*R:attributename] syntax (similar to referencing standard character attributes). The currently active repeating row information will be used to retrieve attribute values. You can also retrieve the full attribute name for a repeating row attribute by using the [*R>attributename] notation. This is useful to pass to things like chatsetattr.
See the section named Repeating Section Access for more information.
Array Elements
After an array has been declared, the elements can be referenced with [@arrayName(index)]. Array indices start at 0.
ScriptCards Settings
It is now possible to reference ScriptCards settings (set with the --# command) using the [~settingname] syntax (ie, [~title] will be replaced with the title setting at the time the reference is interpreted.
Deferred Resolution for Meta Scripts
As of 1.2.9, ScriptCards supports a deferral character for use when calling another API script with via the --@ statement, to defer processing of meta script references so they get processed prior to the sub-API call instead of prior to ScriptCards execution. To defer this processing for meta script (SelectManager, Fetch) by inserting a deferral character into the meta call. For example, if I want to have ScriptCards call TokenMod as if the token for "Quej Gr'stra" (yes, I let Roll20 name my test NPCs) I could use something like this:
--@token-mod|{^& select Quej Gr'stra} _on showname
The ^ in between { and & will prevent SelectManager from seeing the call when the ScriptCard script is processed, but the --@ statement will remove the deferral character so the command that will be sent by ScriptCards is:
!token-mod {& select Quej Gr'stra} --on showname
With the deferral character removed, SelectManager will see the {& select ...} and do its magic.
While the default deferral character is ^, the deferral character is a setting that can be changed:
--#deferralcharacter|%
Will make % the deferral character for future --@ statements in the running script.
Supported Meta Script structures:
-
{^&...}- for SelectManager -
@^(...)and*^(...)for Fetch -
get^.andset^.for Muler ( v 1.4.5+ )
Arrays
Arrays are a new data type introduced in version 1.1.12 of ScriptCards, and are manipulated with associated function (--~) commands.
- Arrays are a lists of strings. Items in an array cannot contain the semi-colon (;) character, as that is used to separate parameters in the function code that deals with arrays.
- Arrays are accessed via the --~ script command. In some cases, the value of the tag (variable name) for array commands is not used, and can be a dummy value or simply omitted. I have omitted them in the statements below.
- All commands that DO return a value return string values, even if the content is numeric.
- If a command returns a value and there is some sort of reason that it isn't an array value, you will get "ArrayError" in the return value. This can happen if you reach the end of an array while stepping through it, for example, so checking for "ArrayError" can serve as the end condition for a loop.
- Each array keeps track of its current index, allowing you to step forward and backwards through arrays.
- Any number of arrays can be defined.
- Unlike string variables and roll variables, array variables cannot (currently) be referenced directly. It is necessary to use the function (--~) syntax to manipulate arrays and get values from them as strings for use in other parts of your script.
Reentrant Scripts
Reentrant scripts allow you to create buttons in your script code that will re-execute the script at a given label within the code. If you set the reentrant setting (--#reentrant|somevalue) to a non-zero value, your setting and variable information will be preserved between executions. Reentrant script can be used to present menus or choices and then continue acting.
Important: The value of the reentrant setting will be used to identify the appropriate script to resume when reentrancy is used. If more than one character can potentially run the same script at the same time, it is a good practice to include the character ID in the reentrant setting in order to maintain a separate list of variables. Something like:
--#reentrant|My Cool Script @{selected|character_id}
Reentrant buttons are created with the [rbutton]Caption::ReentryLabel;Parameter[/rbutton] construct. The caption will be displayed on the generated button. ReentryLabel is the name of a label in your script that the button will jump to when clicked, and Parameter will be passed in as a string value called reentryval.
Example:
!script {{
--#reentrant|testing
--=Roll|1d20
--+Roll|[$Roll]
--&String|That was a [$Roll.Raw]!
--~x|array;define;MyArray;Apple;Banana;Orange
--+Try it|[rbutton]Hello!::EXEC_PC_SPELL;9[/rbutton]
--X|
--:EXEC_PC_SPELL|
--+ReentryVal|[&reentryval]
--+The value of Roll is|[$Roll]
--+Value of String|[&String]
--+Array|[@MyArray(0)]
--X|
}}
This script sets up some variables and then displays a button labeled "Hello!". If the user clicks the button, the script will be re-entered starting at EXEC_PC_SPELL, which will display the content of the variables from the original execution.
Note: This section needs to be expanded upon
Libraries
Procedure Libraries
You can now create handouts in your game in Roll 20 with the name format "ScriptCards Library NAME", where name is a name you assign to the library. Library names are case sensitive. It is my hope that the more proficient ScriptCards scripters out there will provide procedure libraries (or procedures that can be included in libraries) for others to use to make their scripting life easier. Be they specific to a game system, or to a type of activity, I think a robust set of libraries that GMs could use to enhance their scripting capabilities would be very valuable to the community. Should such things begin to emerge, I’ll create a portion of the ScriptCards Wiki page to house them.
To include one or more libraries in a script, use the +++libname+++ directive (does not need a -- line associated with it). Multiple library names can be specified by separating them with semicolons (i.e., +++General;dnd5elib;Colorize+++ would include three libraries (General, dnd5elib, and Colorize).
Included libraries are separated from the main script code by the automatic inclusion of "--X|" before the first library is appended to the script, and all libraries are loaded at the end of the script before script processing takes place.
Procedures and labels in libraries can be used just as if they were included in the body of your script. Note that this DOES mean that you could, technically, jump into a library with a direct branch (--^) or direct branch conditional, but I recommend using libraries to store reusable procedures. The Notes section of the library handout stores the library code, and is written just like any other ScriptCards code except:
- They cannot use roll queries (?{Some Prompt:}) to get information from the user at execution time.
- They cannot use @{} notation to access character and token information.
Both of these limitation stem from the fact that Procedure Libraries are not processed by the chat server, which is what handles these items.
Here is an example of handling damage modifications (resistance, vulnerability, and immunity) in D&D 5E with a library:
!script {{
+++dnd5elib+++
--#|Damage Modifiers Test
--#targettoken|@{target|token_id}
-->Lib5E_CheckDamageModifiers|ResistType;fire
--=DamageRoll|2d10 [&ResistType]
--+Test:|[$DamageRoll] fire damage
-->Lib5E_CheckDamageModifiers|ResistType;cold
--=DamageRoll|2d10 [&ResistType]
--+Test:|[$DamageRoll] cold damage
-->Lib5E_CheckDamageModifiers|ResistType;poison
--=DamageRoll|2d10 [&ResistType]
--+Test:|[$DamageRoll] poison damage
-->Lib5E_CheckDamageModifiers|ResistType;acid
--=DamageRoll|2d10 [&ResistType]
--+Test:|[$DamageRoll] acid damage
--X|
}}
Library content (In a handout called “ScriptCards Library dnd5elib” NOTE: Paste into Notepad first and then paste into the handout in Roll20 to avoid bringing over HTML formatting from the web site):
--/|ScriptCards Library: dnd5elib version 0.0.1 --/|Provides various utility procedures for D&D 5E games --/|Lib5E_CheckDamageModifiers handle damage resistance, vulnerability, and immunity. --/|Pass a string variable to be filled with a string to be appended to a dice roll and the damage type --:Lib5E_CheckDamageModifiers|damageVariableName;damageType --&[%1%]| --?"[*T:npc_vulnerabilities]" -inc "[%2%]"|>_Lib5E_IsVulnerable;[%1%] --?"[*T:npc_resistances]" -inc "[%2%]"|>_Lib5E_IsResistant;[%1%] --?"[*T:npc_immunities]" -inc "[%2%]"|>_Lib5E_IsImmune;[%1%] --<| --:_Lib5E_IsVulnerable| --&[%1%]| * 2 [Vulnerable] --<| --:_Lib5E_IsResistant| --&[%1%]| \ 2 [Resistant] --<| --:_Lib5E_IsImmune| --&[%1%]| * 0 [Immune] --<|
The idea is that the functions in the library create a string that can be appended to a roll to modify the output based on resistances, so you pass Lib5E_CheckDamageModifiers the name of the string variable you want to use and the damage type. The variable (ResistType in this case) will include either nothing, “* 2 [Vulnerable]”, “\ 2 [Resistant]”, or “* 0 [Immune]” which can be included in a roll assignment (--=) to modify the damage as appropriate. The order here might be important if an NPC is misconfigured to be both resistant and immune to the same damage type. Since immune is an absolute, having it last ensures that it will override resistant or vulnerable. A creature that is both vulnerable and resistant (again, misconfigured) will come back as resistant since that condition is checked after vulnerable. Some notes: I prefix my library labels with either “Lib5E_” or “_Lib5E_” as a clarity convention. This isn’t strictly necessary but you should be aware that if two libraries (or if your script and a library) define the same label, the last label defined will win. Since libraries are appended to the end of the script in the order you include them in the +++libname+++ directive, you can somewhat control this, but it is probably best to avoid re-declaring labels.
In my case, items beginning with “Lib5E_” are intended to be called by scripts, while items beginning with “_Lib5E_” are intended to be used as subroutines by the “public” procedures. Of course, there is no reason you couldn’t call them directly.
You might also note that I’ve included some library information in comment lines (--/|) at the top of the library. These are ignored by ScriptCards, and are a good way to convey requirements, parameters, usage information, etc.
Example Libraries
dnd5elib
Download the dnd5elib Library from the ScriptCards GitHub
The dnd5elib library provides a collection of utility procedures that help simplify dealing with the D&D 5E Official Sheet. Some of the procedures in this library require chatsetattr to be installed in your game. This is a growing library, and currently only has a handful of routines. They are:
Procedure Name Notes Lib5E_CheckDamageModifiers parameters, pass the Lib5E_CheckDamageModifiers procedure a variable name (no reference information) and a damage type (i.e., fire, cold, bludgeoning, etc.), and the procedure will then create a string variable with with a name equal to the first parameter that you passed into the procedure. This variable will contain a string that can be included in a roll line (--=), in order to modify the roll as appropriate. For example, -->Lib5E_CheckDamageModifiers|ResistType;fire will check the current target character's attributes for "fire" and will either return an empty string (no references), "* 0 [Immune]" if the creature is immune, "\ 2 [Resistant]" if the creature is resistant, or "* 2 [Vulnerable]" if the creature is vulnerable to fire damage. Lib5E_DeductSpellSlot Pass in a character_id and a slot level, and the script will expend one spell slot of that level, capping the value at 0 slots remaining. For Example -->Lib5E_DeductSpellSlot|@{selected|character_id};1 to deduct a first level spell slot from the selected character. Lib5E_FindResource Used to locate a resource value on a character. Pass in a character_id, a resource name, and two variable names. The procedure will check both repeating and non-repeating resources looking for a resource whose name matches what was passed in and return three variables. The first will be a string variable named for the 3rd parameter and contains the attribute name of the resource's "name" field. The second will be a string variable named after parameter 4 and contains the resource's value field attribute name, and the third variable is a Roll Variable, also named after the 4th parameter that contains the current resource value. Example: -->Lib5E_FindResource|@{selected|character_id};Crossbow bolts;ResName;ResValue will find "Crossbow bolts" as a resource on the character and return [&ResName] which is the name of the resource attribute, [&ResValue] which is the name of the attribute that stores the value and [$ResValue] which is the current numeric value of the resource. Lib5E_Active_Global_Attack_Modifiers Pass a character ID and a string variable to set the return value. This procedure will look through the Global Attack Modifiers (repeating_tohitmod_*) for rows that are active (checked on the character sheet) and return a string with the dice rolls and descriptions for each (for example, if I have "Bless" for 1d4 active and "Being Cool" for +2 active, I will get a return string " + 1d4 [Bless] + 2 [Being Cool]" that can be used in a dice roll. Lib5E_Active_Save_Modifiers Pass a character ID and a string variable to set the return value. This procedure will look through the Global Save Modifiers (repeating_savemod_*) for rows that are active (checked on the character sheet) and return a string with the dice rolls and descriptions for each (for example, if I have "Bless" for 1d4 active and "Being Cool" for +2 active, I will get a return string " + 1d4 [Bless] + 2 [Being Cool]" that can be used in a dice roll. Lib5E_Active_Skill_Modifiers Pass a character ID and a string variable to set the return value. This procedure will look through the Global Skill Modifiers (repeating_skillmod_*) for rows that are active (checked on the character sheet) and return a string with the dice rolls and descriptions for each (for example, if I have "Guidance" for 1d4 active and "Being Cool" for +2 active, I will get a return string " + 1d4 [Guidance] + 2 [Being Cool]" that can be used in a dice roll. Lib5E_Active_AC_Modifiers Pass a character ID and a string variable to set the return value. This procedure will look through the Global Save Modifiers (repeating_savemod_*) for rows that are active (checked on the character sheet) and return a string with the dice rolls and descriptions for each (for example, if I have "Shield of Faith" with a value of 2 active, I will get a return string " + 2 [Shield of Faith]" that can be used in a dice roll. Lib5E_Active_Damage_Modifiers Pass a character ID and TWO string variable to set the return value. The first string will be for normal damage, and the second will be the additional damage on a crit. This procedure will look through the Global Damage Modifiers (repeating_damagemod_*) for rows that are active (checked on the character sheet) and return two strings with the dice rolls and descriptions for them (for example, if I have "Sneak Attack" with a value of 1d6 normal and 1d6 critical damage active, I will get a return string " + 1d6 [Sneak Attack]" and another string of " + 1d6 [Sneak Attack CRIT]" that can be used in a dice rolls. Lib5E_DivineSmiteDice Used to calculate the number of dice to be rolled for a paladin's Divine Smite. Pass a target token id, a spell slot level, and a string variable to be set to the dice roll amount based on the NPC_TYPE attribute of the target token. The returned variable will contain a dice roll (like "3d8" that can be used in a --= line) Lib5E_Character_Summary Pass a character ID to outputs a mini character sheet, including clickable buttons for attacks, actions, legendary actions, etc. Will automatically detect a PC vs NPC and output the appropriate sections.
Due to formatting issues with the Wiki, the library code has been moved to a GITHUB GIT. Please view the GIST in raw mode and copy the text and paste it into a handout called "ScriptCards Library dnd5elib" in your Roll20 Game.
What to Know if you are Coming from PowerCards
While ScriptCards and PowerCard have very similar output goals, their internals and use are quite different. The table below summarizes some of the major differences between the scripts. With its built in roll parser and true variable support, ScriptCards allows for much more powerful and flexible macro creation than what is possible in PowerCards simply because of its design.
PowerCards ScriptCards With a handful of exceptions, all lines in a PowerCard macro are intended to produce a line of output on the final card. With ScriptCards, ONLY the --+and--*statement types produces outputPowerCards lines begin with two dashes ( --) followed by a unique tag name for the line, followed by a vertical bar and the content for the line.ScriptCards lines begin with two dashes ( --) followed by a statement type identifier, which is a single character that identifies the type of line to the interpreter. This is followed by a tag (frequently optional), a vertical bar, and the parameters for the statement being executed.PowerCard macros are always processed top to bottom. Lines can be hidden so they don't output anything, but there is no looping or branching ( --SkipTolooks like a branch, but it just hides all of the lines until the referenced label.)ScriptCards scripts support true branching, including direct branching ( --^) and procedure branching (-->) and (--<). Procedures support parameters and a call stack so procedures can be nested to call other procedures. In addition, the --% statement type can be used to create for...next loops.All lines in a PowerCards macro need to have unique tags because PowerCards builds the card as a single JavaScript object using the tag names to store what will be displayed. This is why repeated tag names always result in the last one being shown. ScriptCards tags do not need to be unique, and in the case of many line types are optional. PowerCards conditionals result in either showing or hiding the line they are on. ScriptCards conditionals support branching, variable setting, loop control, and statement block initiation. Because conditional lines do not produce output on their own, the true/false value doesn't impact the display directly. PowerCards relies on the Roll20 Quantum Roll server and inline rolls for all dice functions ScriptCards includes its own dice roll parser, and does not parse inline rolls. If an inline roll is passed to ScriptCards, it will insert the final value of the roll in the place of the roll in the macro, but they are not part of or parsed by the built-in roll parser and cannot reference ScriptCards variables or updated while the script is running. PowerCards RollIDs (often mistaken for variables) are assigned by analyzing the results of an inline roll, and cannot be referenced in other rolls, so you can't roll a 1d4and then roll a1d20and add the1d4result because all of the rolls happen on the chat server before PowerCards gets the macro text.ScriptCards supports two types of variables: Roll VariablesandString Variables. Because ScriptCards uses its own roll parser and is not dependent upon the chat server, rolls and their results can be used in other rolls, math functions, output, etc.
Example Scripts
Note: The features available in ScriptCards have changed drastically since these examples were written. While these should still work, there are in many cases better ways to do things using language features introduces after these were constructed. Please see the Script Examples section of the official ScriptCards GitHub repository for more updated script examples.
Below are some sample scripts that utilize the various statement types in ScriptCards:
Divine Smite
This script will prompt the user for a spell slot level to expend on a divine smite. It will check the target's npc_type to see if it is an Undead or Fiend, which adds an additional d8 to the smite roll.
!scriptcard {{
--#title|Divine Smite
--=DiceCount|?{Spell Slot Level?|1|2|3|4|5|6|7|8|9} + 1
--=IsFiendOrUndead|0
--?"@{target|npc_type}" -inc fiend|>IsBoosted
--?"@{target|npc_type}" -inc undead|>IsBoosted
--=TotalDice|[$DiceCount] + [$IsFiendOrUndead]
--=SmiteRoll|[$TotalDice]d8
--#emoteText|@{selected|token_name} smites @{target|token_name}
--#sourceToken|@{selected|token_id}
--#targetToken|@{target|token_id}
--+Smite|deals [$SmiteRoll] radiant damage.
--X|
--:IsBoosted|
--=IsFiendOrUndead|1
--<|
}}
How It Works
The first line sets the "title" card parameter to "Divine Smite".
Line 2 Shows a query to the user asking for the spell slot level, adds one and stores the value in the "DiceCount" Roll Variable. The query/dropdown is generated by the chat server prior to the script being executed.
Line 3 defaults the "IsFiendOrUndead" Roll Variable to 0.
Lines 4 and 5 compare the target's "npc_type" attribute (passed by the chat server as text) to see if they include either "undead" or "fiend". If true, the IsBoosted subroutine will be called. No parameters are passed to this subroutine.
Line 6 sets the "TotalDice" variable to the base (DiceCount) number plus the IsFiendOrUndead number, which will be a 0 or a 1.
Line 7 calculates "SmiteRoll" by rolling a number of d8 equal to the "TotalDice" value.
Lines 8-10 set the parameters for the emote, which appears above the card content. By setting the sourceToken and the targetToken, their icons will appear in the emote surrounding the text describing the action.
Line 11 is the only line that actually produces output on the card. It results in "Smite deals # radiant damage".
Line 12 ends the script execution, preventing the script from continuing and running the subroutines out of context.
Lines 14-16 are the IsBoosted subroutine, starting with the :IsBoosted label. The IsFiendOrUndead variable is set to 1, and a return from subroutine is executed.
Alternative Script
!scriptcard {{
--#title|Divine Smite
--#sourceToken|@{selected|token_id}
--#targetToken|@{target|token_id}
--=DiceCount|?{Spell Slot Level?|1|2|3|4|5|6|7|8|9} + 1
--?"@{target|npc_type}" -inc fiend -or "@{target|npc_type}" -inc undead|=DiceCount;[$DiceCount.Raw] + 1
--=SmiteRoll|[$DiceCount]d8
--#emoteText|@{selected|token_name} smites @{target|token_name}
--+Smite|deals [$SmiteRoll] radiant damage.
}}
This version of the Divine Smite script has identical output to the script above, but is greatly simplified by using language features introduced later in the ScriptCards development cycle. Instead of a subroutine that is called based on the undead or fiend values as separate checks, a single conditional is used joined by an -or. The expanded capability of conditionals to set variables is then used to add one to the DiceCount if the conditional statement is true.
Magic Missile
This script demonstrates using a loop and calling a subroutine to fire a number of missiles determine by the spell slot level used to cast the spell.
!scriptcard {{
--#title|Magic Missile
--#sourceToken|@{selected|token_id}
--#targetToken|@{target|token_id}
--=MissileCount|?{Spell Slot Level?|1|2|3|4|5|6|7|8|9} + 2
--=DisplayCount|1
--=MissileDamage|0
--#leftsub|Slot level ?{Spell Slot Level?}
--#rightsub|Ranged Attack
--#emoteText|Fred uses a level ?{Spell Slot Level?} spell slot to fire [$MissileCount.Total] missiles of magical force!
--:MissileLoop|
-->FireMissile|
--=DisplayCount|[$DisplayCount] + 1
--?[$DisplayCount] -le [$MissileCount]|MissileLoop
--+Total|Total damage is [$MissileDamage]
--X|
--:FireMissile|
--=ThisMissile|1d4 + 1
--=MissileDamage|[$MissileDamage] + [$ThisMissile]
--+Missile|[$DisplayCount.Total] Hits for [$ThisMissile] [b]force[/b] damage
--<|
}}
How It Works
Lines 1-3 set the card title, the source token and the target token. Setting these tokens causes their icons/avatars to appear in the Emote section of the card.
Line 4 asks the user what spell slot level they wish to use to cast magic missile. The number of missiles fired is equal to 2 plus the spell level, and this is stored in the MissileCount variable.
Line 5 stores a 1 in the DisplayCount variable. This will be used to control the loop to determine the number of missiles fired and the missile number when displaying damage rolls.
Line 6 initializes MissileDamage to 0
Line 7 sets the left subtitle to the text "Slot Level #", where # is the spell slot level being used.
Line 8 sets the right subtitle to the text "Ranged Attack".
Line 9 sets the emoteText parameter with a description of the action, including the slot level and number of missiles fired.
Line 10 is a label for the missile firing loop
Line 11 Calls the "FireMissile" subroutine
Line 12 increases the DisplayCount variable by 1
Line 13 Checks to see if there are still missles to fire (DisplayCount <= MissileCount) and if so branches to MissileLoop
Line 14 Displays the total damage dealt by the spell.
Line 15 stops execution of the script to prevent out of context execution of the subroutine.
Lines 76-21 are the FireMissile subroutine, beginning with the FireMissile label. The 1d4+1 is rolled and assigned to "ThisMissile". The result is added to the existing MissileDamage total, and a line for the current missile is displayed with the missile number and the damage for the missile.
Longsword Attack
This script demonstrates a standard 5E D&D melee weapon attack, including detection of misses, fumbles, hits, and critical hits. If installed, alterbars is used to decrement the target's BAR3 value by the damage dealt.
!scriptcard {{
--#title|Longsword
--#leftsub|Melee Attack

--+Critical Hit!|The attack hit @{target|token_name} for [$Damage] slashing damage.
--@alter|_target|@{target|token_id} _bar|3 _amount|-[$Damage]
--:Final|
}}
How it Works
In lines 1-5, we set the title, subtitle, and emote text along with the tokens for the emote area.
Lines 6-9 allow us to determine the AC of the target. On the 5E Roll20 sheet, NPCs armor class is stored in "npc_ac", while PCs armor class is in "ac". First we grab npc_ac and if it is zero, we check AC.
Line 10 rolls the attack roll, rolling 1d20 and adding the attacker's strength modifier and proficiency bonus
Line 11 displays the result of the attack roll on the card
Lines 12-14 determine what kind of result the attack had. If the .Base value of the roll was 20, we branch to "Crit". If it was 1, we branch to "Fumble". If the .Total value of the roll was greater than or equal to the AC that was determined in Lines 6-9, we branch to Hit.
Assuming we didn't branc anywhere, the result of the attack was a miss, so we display that on line 15 and then branch to "Final"
This is followed by three branch segments, :Fumble, :Hit, and :Crit. A fumble displays a text message and branches to :Final.
On a hit or a crit, we roll Damage (adding additional damage dice on a crit). We display a "Hit!" or "Critical Hit!" message and then make an API call to AlterBars, passing it the token id, bar we want to modify (3 in this case), and the amount we want to modify by the Damage value.
Party Health Status
This example calculates the current Hit Points remaining and HP percentage for each character and creates a color-coded display with the current party status.
!scriptcard {{
--#title|Party Status
--#titleCardBackground|#33CC33
--#oddrowbackground|#bfee90
--#evenrowbackground|#90eebf

--=HealthColor|FF0000
--:HealthSkip|

--<|End of HealthCheck
}}
How it Works
Lines 1-4, we set the card title, and set the title background and row background colors to shades of green.
Lines 5-7 make gosub calls the the "HealthCheck" subroutine, passing in the character ID of each of the named characters (these are the names of the characters in my test game)
Line 8 terminates the script execution.
The remaining lines of the script are the HealthCheck subroutine, which works like this:
Line 10 is the subroutine label (:HealthCheck)
Line 11 uses the character id passed as a parameter and combines it with character attribute lookup *(...) to retrieve the value of "hp" and "hp^" for the character. The ^ character is used to specify that we want the MAX value for this attribute for the second call. We divide these two numbers and multiple by 100 to get a percentage. Finally, we use integer division by 1 to round the percentage and drop the decimals. The end result gets stored in the HealthPerc roll variable.
Line 12 defaults to color of the health text to black
Line 13 check to see if the health percentage is greater than 50. If so, it branches to HealthSkip, preventing the script from executing line 13.
Line 14 sets the color of the health text to red
Line 15 is the label that will be branched to from Line 13 to skip the red coloring
Line 16 again uses character attribute substitution and the passed parameter value to output a display line containing the character name, the colorized health total, and the percentage value. The percentage is right-justified.
Line 17 returns from the HealthCheck subroutine.
