== Types of Objects ==
  
 
There are several different types of objects that are used throughout the Roll20 API. Here's a quick listing of each, what it is, and what properties it contains (along with the default values). As a general rule of thumb, properties that begin with an underscore (_) are '''read-only''' and cannot be changed. You must access properties on objects using <code>obj.get("property")</code> and set new values using <code>obj.set("property", newvalue)</code> or <code>obj.set({property: newvalue, property2: newvalue2})</code>.

'''Note:''' The <code>id</code> property of an object is a globally-unique ID: no two objects should have the same one, even across different types of objects. In addition, since an object's id is frequently-accessed and never changes, there is a shortcut available where you can access it by using <code>obj.id</code> instead of <code>obj.get("_id")</code> if you wish (either will work).

You can choose to respond to either event, but the underlying bar values will not yet be updated when the attribute event fires, since it fires first.

'''Important Notes About Status Markers'''

{

As of August 6, 2013 the way that status markers on tokens are handled has changed. The "statusmarkers" property of the Graphic object is now a comma-delimited list of all status marker colors/icons that should be active on the token. The format is as follows:
  _id: "-Abc123",  
+
  name: "", //Page's title   
+
  showgrid: true, //are we showing the grid?   
+
  showdarkness: false, //Is the Fog of War active?   
+
  showlighting: false, //Is Dynamic Lighting active?   
+
  width: 25, //width in units   
+
  height: 25, //height in units   
+
  snapping_increment: 1.0, //the size of a grid space in units   
+
  grid_opacity: 0.50, //opacity of the grid   
+
  fog_opacity: 0.35, //opacity of the fog of war for the GM   
+
  background_color: "#ffffff", //background color (HEX)   
+
  gridcolor: "#C0C0C0", //grid color (HEX)   
+
  grid_type: "square", //eitehr "square", "hexv", or "hexh"   
+
  scale_number: 5, //1 unit = how much distance   
+
  scale_units: "ft", //scale is in these units   
+
  gridlabels: false, //show grid labels for hex grid

  diagonaltype: "foure", //one of "foure", "pythagorean" (Euclidean), "threefive", or "manhattan"

While you can access the <code>statusmarkers</code> property directly, to maintain backward-compatibility with existing scripts, and to provide an easy way to work with the status markers without needing to write code to handle splitting up and parsing the string yourself, we provide a set of "virtual" properties on the object that you can set/get to work with the status markers. Each status marker has a "status_<markername>" property. For example:
 +
 
 
<pre data-language="javascript">
 
<pre data-language="javascript">
{   
+
obj.get("status_red"); //Will return false if the marker is not active, true if it is, and a string (e.g. "2" or "5") if there is currently a badge set on the marker
  _d20userid: "", //The site-wide unique ID of the user.
+
obj.get('status_bluemarker'); //Is still supported for backwards compatability, and is equivalent to doing obj.get("status_blue");
  _displayname: "", //Current display name   
+
obj.set("status_red", false); //would remove the marker
  _online: false,  
+
obj.set("status_skull", "2"); //would set a badge of "2" on the skull icon, and add it to the token if it's not already active.
  color: "#13B9F0",   
+
  _macrobar: "", //Comma-delimited string of the macros in the player's macro bar.

  showmacrobar: false, //Show macro bar?

'''Turn Order'''
 +
 +
The turn order is a JSON string representing the current turn order listing. It is an array of objects. Currently, the turn order can only contain objects from one page at a time -- the current Page ID for the turn order is the "initiativepage" attribute. Be sure to keep them both in-sync or you may end up with strange results.
 +
 +
To work with the turn order, you will want to use <code>JSON.parse()</code> to get an object representing the current turn order state (NOTE: Check to make sure it's not an empty string <code>""</code> first...if it is, initialize it yourself with an empty array). Here's an example turn order object:
  
===Rollable Table===
 
 
<pre data-language="javascript">
 
<pre data-language="javascript">
{  
+
[
  name: "new-table",  
+
    {
  showplayers: true,  
+
    "id":"36CA8D77-CF43-48D1-8682-FA2F5DFD495F", //The ID of the Graphic object. If this is set, the turn order list will automatically pull the name and icon for the list based on the graphic on the tabletop.
  _type: "rollabletable",  
+
    "pr":"0", //The current value for the item in the list. Can be a number or text.
  _id: ""
+
    "custom":"" //Custom title for the item. Will be ignored if ID is set to a value other than "-1".
}
+
    },
 +
    {
 +
    "id":"-1", //For custom items, the ID MUST be set to "-1" (note that this is a STRING not a NUMBER.
 +
    "pr":"12",
 +
    "custom":"Test Custom" //The name to be displayed for custom items.
 +
    }
 +
]
 
</pre>
 
</pre>
  
 +
To modify the turn order, edit the current turn order object and then use <code>JSON.stringify()</code> to change the attribute on the Campaign. Note that the ordering for the turn order in the list is the same as the order of the array, so for example <code>push()</code> adds an item onto the end of the list, <code>unshift()</code> adds to the beginning, etc.
  
===Table Item===
 
 
<pre data-language="javascript">
 
<pre data-language="javascript">
{   
+
var turnorder;
  name: "",   
+
if(Campaign().get("turnorder") == "") turnorder = []; //NOTE: We check to make sure that the turnorder isn't just an empty string first. If it is treat it like an empty array.
  weight: 1,   
+
else turnorder = JSON.parse(Campaign().get("turnorder"));
  _type: "tableitem",  
+
 
  _id: "",  
+
//Add a new custom entry to the end of the turn order.
  _rollabletableid: "" //ID of the rollable table this item belongs to
+
turnorder.push({
}
+
    id: "-1",
 +
    pr: "15",
 +
    custom: "Turn Counter"
 +
});
 +
Campaign().set("turnorder", JSON.stringify(turnorder));

=== imgsrc and avatar property restrictions ===
 +
 +
While you can now edit the <code>imgsrc</code> and <code>avatar</code> properties, in order to provide safety to all Roll20's users we have put the following restrictions in place for those properties:
 +
 +
* '''You must use an image file that has been uploaded to your Roll20 Library''' -- not an external site (such as Imgur), and not the Roll20 Marketplace. It will begin with 'https://s3.amazonaws.com/files.d20.io/images/' for images uploaded to the Main server, or 'https://s3.amazonaws.com/files.staging.d20.io/images/' for images uploaded to the Dev Server. You can view an image's source URL using the developer tools of your browser.
 +
 +
* You must include the query string in the URL -- for example 'https://s3.amazonaws.com/files.staging.d20.io/images/123456/med.png?12345678', not just 'https://s3.amazonaws.com/files.staging.d20.io/images/123456/med.png'
 +
 +
* For Graphic objects (tokens), you must use the "thumb" size of the image. It should look like 'https://s3.amazonaws.com/files.staging.d20.io/images/123456/thumb.png?12345678'.
 +
 +
 +
In the future we may add a tool so that images can be uploaded specifically for use with API scripts, but for now just use images uploaded to your own library. Note that if you delete an image from your library, it will be removed from all Games which use that image, including Games using your API scripts.
 +
 +
=== Using the Notes, GMNotes, and Bio fields {{Asynchronous}} ===
 +
 +
In order to access the "notes", "gmnotes", or "bio" fields on Characters and Handouts, you must pass a callback function as the second argument to the get() function. Here's an example:
  
===Ability===
 
 
<pre data-language="javascript">
 
<pre data-language="javascript">
{   
+
var character = getObj("character", "-JMGkBaMgMWiQdNDwjjS");
  name: "Untitled_Ability",  
+
character.get("bio", function(bio) {
  description: "",   
+
    log(bio); //do something with the character bio here.
  action: "",  
+
});</pre>
  _id: "",   
+
  _characterid: "",   
+
  _type: "ability" 
+
}
+
</pre>
+
  
 +
You can set the value of these fields as normal. Note that there is currently (as at 2016/05/09) a bug with these asynchronous fields, whereby setting them by passing values to createObj fails quietly, leaving the object in a strange state. You should only set these values using .set until this issue is resolved. Details on the [https://app.roll20.net/forum/post/3345763/async-notes-slash-gmnotes-dont-work-immediately-after-creation forum]. There is also a bug (as of 2016/11/05) where attempting to set both the notes and gmnotes properties in the same set() call results in the second property in the call being set erroneously. Details on the [https://app.roll20.net/forum/post/4206469/api-bug-setting-handout-gmnotes-at-the-same-time-as-notes-gives-random-large-integer-or-blank-string/?pageforid=4206469#post-4206469 forum].
 +
 +
=== Working with Character Sheets ===
 +
 +
The Character Sheets feature affects the usage of the Attributes object type, because the sheets have the capability of specifying a default value for each attribute on the sheet. However, if the attribute is set to the default value, there is not yet an actual Attribute object created in the game for that Character. We provide a convenience function which hides this complexity from you. You should use this function to get the value of an attribute going forward, especially if you know that a game is using a Character Sheet.
 +
 +
'''getAttrByName(character_id, attribute_name, value_type)'''
 +
 +
Simply specify the character's ID, the '''name''' (not ID) of the attribute (e.g. "HP" or "Str"), and then if you want the "current" or "max" for value_type. Here's an example:
  
===Handout===
 
 
<pre data-language="javascript">
 
<pre data-language="javascript">
{   
 
  name: "Mysterious Note",   
 
  notes: "",   
 
  inplayerjournals: "", //Comma-delimited list of Player IDs who can see this Handout in their journal. The GM can always see the Handout. 
 
  archived: false,   
 
  controlledby: "", //Comma-delimited list of Player IDs who can control (and edit) this Handout. 
 
  _type: "handout",   
 
  _id: ""
 
}
 
</pre>
 
  
==Creating Objects==
+
var character = getObj("character", "-JMGkBaMgMWiQdNDwjjS");
 +
getAttrByName(character.id, "str"); // the current value of str, for example "12"
 +
getAttrByName(character.id, "str", "max"); //the max value of str, for example "[[floor(@{STR}/2-5)]]"</pre>
  
{{mbox | text= Note: Currently only '''characters, handouts, attributes, and abilities''' can be created. Other objects will be supported soon.}}
+
Note that fields which have auto-calculated values will return the formula rather than the result of the value. You can then pass that formula to sendChat() to use the dice engine to calculate the result for you automatically.  
  
 +
Be sure to also look at the [[Character Sheet]] documentation for more information on how the Character Sheets interact with the API.
 +
 +
<code>getAttrByName</code> will ''only'' get the value of the attribute, not the attribute object itself. If you wish to reference properties of the attribute other than "current" or "max", or if you wish to change properties of the attribute, you must use one of the other functions above, such as <code>findObjs</code>.
 +
 +
In the case that the requested attribute does not exist, <code>getAttrByName()</code> will return <code>undefined</code>.
 +
 +
== Creating Objects ==
  
 
'''createObj(type, attributes)'''
 
'''createObj(type, attributes)'''
  
You can create a new object in the game using the <code>createObj</code> function. You must pass in the type of the object (one of the valid <code>_type</code> properties from the objects list above), as well as a an <code>attributes</code> object containing a list of properties for the object. Note that if the object is has a parent object (for example, attributes and abilities belong to characters), you must pass in the ID of the parent in the list of properties (for example, you must include the <code>characterid</code> property when creating an attribute). Also note that even when creating new objects, you can't set read-only properties, they will automatically be set to their default value.
+
''Note: currently you can create {{creatable objects}} objects.''

Also note that even when creating new objects, you can't set read-only properties, they will automatically be set to their default value. The one exception to this is when creating a Path, you must include the 'path' property, but it cannot be modified once the path is initially created.
  
 
<code>createObj</code> will return the new object, so you can continue working with it.

== Deleting Objects ==
 +
 
 +
'''object.remove()'''
 +
 
 +
''Note: currently you can delete {{creatable objects}} objects.''
 +
 
 +
You can delete existing game objects using the <code>.remove()</code> function. The .remove() function works on all of the objects you can create with the createObj function. You call the function directly on the object. For example, <code>mycharacter.remove();</code>.
 +
 
 +
== Global Objects ==
 
There are several objects that are globally available anywhere in your script.
 
There are several objects that are globally available anywhere in your script.
  
'''<code>Campaign()</code>''' (function)
+
===Campaign() (function)===
  
A function which returns the <code>Campaign</code> object. Since there is only one campaign, this global always points to the only campaign in the game. Useful for doing things like checking to see if an object is on the active page using <code>Campaign().playerpageid</code>.
+
A function which returns the <code>Campaign</code> object. Since there is only one campaign, this global always points to the only campaign in the game. Useful for doing things like checking to see if an object is on the active page using <code>Campaign().get("playerpageid")</code>.
  
'''<code>state</code>'''
+
===state===
  
This is an object that is initialized as a blank object whenver your script is loaded. You can set whatever properties you want on this object, and they are available to all of your event callbacks, and persist between callbacks. In addition, the <code>state</code> object is persisted between play sessions, so you can use this object to store long-term information about the state of the game.
+
The <code>state</code> variable is an object in the global scope which is accessible to all scripts running in a game. You can access the <code>state</code> object from any function or callback at any time just by using the global variable named <code>state</code>.   Additionally, the <code>state</code> object is persisted between executions of the [[API:Sandbox_Model|Sandbox]], so you can use it to store information you want to have in future runs of your script.
  
You should use the state object to store information that is only related to the API, since it is not sent to player computers and does not make your campaign file larger, and store properties that are needed in-game in the objects themselves.
+
'''Note:''' You should use the state object to store information that is only needed by the API, since it is not sent to player computers and does not make your game file larger.  Store values that are needed in-game in the Roll20 objects' properties.
  
 +
====Storable Types====
 +
The <code>state</code> object is only capable of persisting simple data types, as supported by the [http://json.org JSON] standard.
 +
 +
{| class="wikitable"
 +
|-
 +
! Type !! Examples !! Description
 +
|-
 +
| Boolean || <code>true</code> <code>false</code> || The value <code>true</code> or <code>false</code>.
 +
|-
 +
| Number || <code>123.5</code> <code>10</code> <code>1.23e20</code>  || Any number format supported by Javascript.  Floating-Point or Integer.
 +
|-
 +
| String || <code>'Hello Fantasy'</code> <code>"oh, and World"</code>  || A standard string of text.
 +
|-
 +
| Array || <code>[ 1, 2, 3, 4 ]</code> <code>[ 'A','B','C']</code><code>[1, 2, ['bob', 3], 10, 2.5]</code>  || An ordered collection of any of the types, including other arrays.
 +
|-
 +
| Object || <code>{ key: 1, value: 'roll20' }</code> || A simple key/value object with string keys and any of the types as a value, including other objects.
 +
|}
 +
 +
'''Warning:''' While functions will appear to work when stored in the state initially, they will disappear the first time the <code>state</code> is restored from persistence, such as on a sandbox restart. 
 +
* '''Note:''' This includes Roll20 objects which you get from events or the functions <code>findObjs()</code>, <code>getObj()</code>, <code>filterObjs()</code>, <code>createObj()</code>, etc.
 +
 +
====Important Reminders====
 +
The <code>state</code> object is shared between all of the scripts in a sandbox.  To avoid breaking other scripts, it is important to follow a few simple guidelines:
 +
* '''''Never''''' assign directly to the root <code>state</code> object.
 
<pre data-language="javascript">
 
<pre data-language="javascript">
state.numTimesTokensMoved = 0;
+
state = { break: 'all the things' };  // NEVER DO THIS!!!
on("change:graphic", function(obj) {  
+
</pre>
  state.numTimesTokensMoved = state.numTimesTokensMoved + 1;
+
 
 +
* '''''Avoid''''' using local variables named <code>state</code> in your scripts. While this will work, it will be confusing to later users of your scripts and could cause issues if the code is carelessly edited.
 +
<pre data-language="javascript">
 +
function turn(){
 +
    var state = Campaign().get('turnorder');  // Bad Practice, Avoid it!
 +
    // ...
 +
}
 +
</pre>
 +
 
 +
* '''''Always''''' place your properties beneath at least one namespace property.  Be sure to use a sufficiently descriptive namespace property.  Avoid names like <code>script</code> or <code>settings</code>.  It's best to either use the name of your module or your own name or handle.
 +
<pre data-language="javascript">
 +
if( ! state.MyModuleNamespace ) {
 +
    state.MyModuleNamespace = { module: 'my module', ok: 'this is fine!', count: 0 };
 +
}
 +
state.MyModuleNamespace.count++;
 +
</pre>
 +
 
 +
====Example Usage====
 +
This is a working example that uses the <code>state</code> object appropriately.
 +
 
 +
<pre data-language="javascript">
 +
on('ready',function() {
 +
    "use strict";
 +
 
 +
    // Check if the namespaced property exists, creating it if it doesn't
 +
    if( ! state.MyModuleNS ) {
 +
        state.MyModuleNS = {
 +
            version: 1.0,
 +
            config: {
 +
                color1: '#ff0000',
 +
                color2: '#0000ff'
 +
            },
 +
            count: 0
 +
        };
 +
    }
 +
 
 +
    // Using the state properties to configure a message to the chat.  
 +
    sendChat(
 +
        'Test Module',
 +
        '<span style="color: '+state.MyModuleNS.config.color1+';">'+
 +
            'State test'+
 +
        '</span> '+
 +
        '<span style="color: '+state.MyModuleNS.config.color2+';">'+
 +
            'Script v'+state.MyModuleNS.version+' started '+(++state.MyModuleNS.count)+' times!'+
 +
        '</span>'
 +
    );
 
});
 
});

===getAttrByName(character_id, attribute_name, value_type)===
 +
 
 +
Gets the value of an attribute, using the default value from the character sheet if the attribute is not present. <code>value_type</code> is an optional parameter, which you can use to specify "current" or "max".
 +
 
 +
<code>getAttrByName</code> will ''only'' get the value of the attribute, not the attribute object itself. If you wish to reference properties of the attribute other than "current" or "max", or if you wish to change properties of the attribute, you must use one of the other functions above, such as <code>findObjs</code>.
 +
 
 +
For repeating sections, you can use the format <code>repeating_section_$n_attribute</code>, where <code>n</code> is the repeating row number (starting with zero). For example, <code>repeating_spells_$2_name</code> will return the value of <code>name</code> from the third row of <code>repeating_spells</code>.
 +
 
 +
You can achieve behavior equivalent to <code>getAttrByName</code>with the following:
 +
<pre data-language="javascript">
 +
// current and max are completely dependent on the attribute and game system
 +
// in question; there is no function available for determining them automatically
 +
function myGetAttrByName(character_id,
 +
                        attribute_name,
 +
                        attribute_default_current,
 +
                        attribute_default_max,
 +
                        value_type) {
 +
    attribute_default_current = attribute_default_current || '';
 +
    attribute_default_max = attribute_default_max || '';
 +
    value_type = value_type || 'current';
 +
 
 +
    var attribute = findObjs({
 +
        type: 'attribute',
 +
        characterid: character_id,
 +
        name: attribute_name
 +
    }, {caseInsensitive: true})[0];
 +
    if (!attribute) {
 +
        attribute = createObj('attribute', {
 +
            characterid: character_id,
 +
            name: attribute_name,
 +
            current: attribute_default_current,
 +
            max: attribute_default_max
 +
        });
 +
    }
 +
 
 +
    if (value_type == 'max') {
 +
        return attribute.get('max');

[edit] Types of Objects

There are several different types of objects that are used throughout the Roll20 API. Here's a quick listing of each, what it is, and what properties it contains (along with the default values). As a general rule of thumb, properties that begin with an underscore (_) are read-only and cannot be changed. You must access properties on objects using obj.get("property") and set new values using obj.set("property", newvalue) or obj.set({property: newvalue, property2: newvalue2}).

Note: The id property of an object is a globally-unique ID: no two objects should have the same one, even across different types of objects. In addition, since an object's id is frequently-accessed and never changes, there is a shortcut available where you can access it by using obj.id instead of obj.get("_id") if you wish (either will work).

[edit] Path

Property Default Value Notes
_id A unique ID for this object. Globally unique across all objects in this game. Read-only.
_type "path" Can be used to identify the object type or search for the object. Read-only.
_pageid ID of the page the object is in. Read-only.
_path A JSON string describing the lines in the path. Read-only, except when creating a new path. See Objects/Path for more information.
fill "transparent" Fill color. Use the string "transparent" or a hex color as a string, for example "#000000"
stroke "#000000" Stroke (border) color.
rotation 0 Rotation (in degrees).
layer "" Current layer, one of "gmlayer", "objects", "map", or "walls". The walls layer is used for dynamic lighting, and paths on the walls layer will block light.
stroke_width 5
width 0
height 0
top 0 Y-coordinate for the center of the path
left 0 X-coordinate for the center of the path
scaleX 1
scaleY 1
controlledby "" Comma-delimited list of player IDs who can control the path. Controlling players may delete the path. If the path was created by a player, that player is automatically included in the list.

All Players is represented by having 'all' in the list.

For more information on the format of _path data, see: Objects/Path

[edit] Text

Property Default Value Notes
_id A unique ID for this object. Globally unique across all objects in this game. Read-only.
_type "text" Can be used to identify the object type or search for the object. Read-only.
_pageid ID of the page the object is in. Read-only.
top 0
left 0
width 0

Important Notes About Linked Characters + Tokens

Note that for tokens that are linked to Characters, the controlledby field on the token is overridden by the controlledby field on the Character.

For token bars (e.g. bar1_value and bar1_max) where the token is linked to an Attribute (e.g. bar1_link is set), setting a value to the bar will automatically update the underlying Attribute's current and/or max values as well, so you don't have to set both manually.

In addition, when the Attribute (or token bar) is modified in-game, you will hear a change:attribute (and property-specific, e.g. change:attribute:current) event, followed by a change:graphic (and change:graphic:bar1_value) event. You can choose to respond to either event, but the underlying bar values will not yet be updated when the attribute event fires, since it fires first.

Important Notes About Status Markers

As of August 6, 2013 the way that status markers on tokens are handled has changed. The "statusmarkers" property of the Graphic object is now a comma-delimited list of all status marker colors/icons that should be active on the token. The format is as follows:

//Comma-delimited (use join to create or split to turn into an array). If a status icon/color is followed by an "@" symbol, the number after "@" will be shown as the badge on the icon
statusmarkers = "red,blue,skull,dead,brown@2,green@6"

While you can access the statusmarkers property directly, to maintain backward-compatibility with existing scripts, and to provide an easy way to work with the status markers without needing to write code to handle splitting up and parsing the string yourself, we provide a set of "virtual" properties on the object that you can set/get to work with the status markers. Each status marker has a "status_<markername>" property. For example:

obj.get("status_red"); //Will return false if the marker is not active, true if it is, and a string (e.g. "2" or "5") if there is currently a badge set on the marker
obj.get('status_bluemarker'); //Is still supported for backwards compatability, and is equivalent to doing obj.get("status_blue");
obj.set("status_red", false); //would remove the marker
obj.set("status_skull", "2"); //would set a badge of "2" on the skull icon, and add it to the token if it's not already active.

Note that these virtual properties do not have events, so you must use change:graphic:statusmarkers to listen for changes to the status markers of a token, and for example change:graphic:status_red is NOT a valid event and will never fire.

The full list of status markers that are available (in the same order they appear in the marker tray):

"red", "blue", "green", "brown", "purple", "pink", "yellow", "dead", "skull", "sleepy", "half-heart", "half-haze", "interdiction", "snail", "lightning-helix", "spanner", "chained-heart", "chemical-bolt", "death-zone", "drink-me", "edge-crack", "ninja-mask", "stopwatch", "fishing-net", "overdrive", "strong", "fist", "padlock", "three-leaves", "fluffy-wing", "pummeled", "tread", "arrowed", "aura", "back-pain", "black-flag", "bleeding-eye", "bolt-shield", "broken-heart", "cobweb", "broken-shield", "flying-flag", "radioactive", "trophy", "broken-skull", "frozen-orb", "rolling-bomb", "white-tower", "grab", "screaming", "grenade", "sentry-gun", "all-for-one", "angel-outfit", "archery-target"

_jukeboxfolder "" A JSON string which contains data about the jukebox playlist structure of the game. Read-only.

Turn Order

The turn order is a JSON string representing the current turn order listing. It is an array of objects. Currently, the turn order can only contain objects from one page at a time -- the current Page ID for the turn order is the "initiativepage" attribute. Be sure to keep them both in-sync or you may end up with strange results.

To work with the turn order, you will want to use JSON.parse() to get an object representing the current turn order state (NOTE: Check to make sure it's not an empty string "" first...if it is, initialize it yourself with an empty array). Here's an example turn order object:

[
    {
     "id":"36CA8D77-CF43-48D1-8682-FA2F5DFD495F", //The ID of the Graphic object. If this is set, the turn order list will automatically pull the name and icon for the list based on the graphic on the tabletop.
     "pr":"0", //The current value for the item in the list. Can be a number or text.
     "custom":"" //Custom title for the item. Will be ignored if ID is set to a value other than "-1".
    },
    {
     "id":"-1", //For custom items, the ID MUST be set to "-1" (note that this is a STRING not a NUMBER.
     "pr":"12",
     "custom":"Test Custom" //The name to be displayed for custom items.
    }
]

To modify the turn order, edit the current turn order object and then use JSON.stringify() to change the attribute on the Campaign. Note that the ordering for the turn order in the list is the same as the order of the array, so for example push() adds an item onto the end of the list, unshift() adds to the beginning, etc.

var turnorder;
if(Campaign().get("turnorder") == "") turnorder = []; //NOTE: We check to make sure that the turnorder isn't just an empty string first. If it is treat it like an empty array.
else turnorder = JSON.parse(Campaign().get("turnorder"));

//Add a new custom entry to the end of the turn order.
turnorder.push({
    id: "-1",
    pr: "15",
    custom: "Turn Counter"
});
Campaign().set("turnorder", JSON.stringify(turnorder));

[edit] imgsrc and avatar property restrictions

While you can now edit the imgsrc and avatar properties, in order to provide safety to all Roll20's users we have put the following restrictions in place for those properties:


In the future we may add a tool so that images can be uploaded specifically for use with API scripts, but for now just use images uploaded to your own library. Note that if you delete an image from your library, it will be removed from all Games which use that image, including Games using your API scripts.

[edit] Using the Notes, GMNotes, and Bio fields [Asynchronous]

In order to access the "notes", "gmnotes", or "bio" fields on Characters and Handouts, you must pass a callback function as the second argument to the get() function. Here's an example:

var character = getObj("character", "-JMGkBaMgMWiQdNDwjjS");
character.get("bio", function(bio) {
    log(bio); //do something with the character bio here.
});

You can set the value of these fields as normal. Note that there is currently (as at 2016/05/09) a bug with these asynchronous fields, whereby setting them by passing values to createObj fails quietly, leaving the object in a strange state. You should only set these values using .set until this issue is resolved. Details on the forum. There is also a bug (as of 2016/11/05) where attempting to set both the notes and gmnotes properties in the same set() call results in the second property in the call being set erroneously. Details on the forum.

[edit] Working with Character Sheets

The Character Sheets feature affects the usage of the Attributes object type, because the sheets have the capability of specifying a default value for each attribute on the sheet. However, if the attribute is set to the default value, there is not yet an actual Attribute object created in the game for that Character. We provide a convenience function which hides this complexity from you. You should use this function to get the value of an attribute going forward, especially if you know that a game is using a Character Sheet.

getAttrByName(character_id, attribute_name, value_type)

Simply specify the character's ID, the name (not ID) of the attribute (e.g. "HP" or "Str"), and then if you want the "current" or "max" for value_type. Here's an example:


var character = getObj("character", "-JMGkBaMgMWiQdNDwjjS");
getAttrByName(character.id, "str"); // the current value of str, for example "12"
getAttrByName(character.id, "str", "max"); //the max value of str, for example "[[floor(@{STR}/2-5)]]"

Note that fields which have auto-calculated values will return the formula rather than the result of the value. You can then pass that formula to sendChat() to use the dice engine to calculate the result for you automatically.

Be sure to also look at the Character Sheet documentation for more information on how the Character Sheets interact with the API.

getAttrByName will only get the value of the attribute, not the attribute object itself. If you wish to reference properties of the attribute other than "current" or "max", or if you wish to change properties of the attribute, you must use one of the other functions above, such as findObjs.

In the case that the requested attribute does not exist, getAttrByName() will return undefined.

[edit] Creating Objects

createObj(type, attributes)

Note: currently you can create 'graphic', 'text', 'path', 'character', 'ability', 'attribute', 'handout', 'rollabletable', 'tableitem', and 'macro' objects.

You can create a new object in the game using the createObj function. You must pass in the type of the object (one of the valid _type properties from the objects list above), as well as an attributes object containing a list of properties for the object. Note that if the object is has a parent object (for example, attributes and abilities belong to characters, graphics, texts, and paths belong to pages, etc.), you must pass in the ID of the parent in the list of properties (for example, you must include the characterid property when creating an attribute). Also note that even when creating new objects, you can't set read-only properties, they will automatically be set to their default value. The one exception to this is when creating a Path, you must include the 'path' property, but it cannot be modified once the path is initially created.

createObj will return the new object, so you can continue working with it.

//Create a new Strength attribute on any Characters that are added to the game.
on("add:character", function(obj) {
    createObj("attribute", {
        name: "Strength",
        current: 0,
        max: 30,
        characterid: obj.id
    });
});

[edit] Deleting Objects

object.remove()

Note: currently you can delete 'graphic', 'text', 'path', 'character', 'ability', 'attribute', 'handout', 'rollabletable', 'tableitem', and 'macro' objects.

You can delete existing game objects using the .remove() function. The .remove() function works on all of the objects you can create with the createObj function. You call the function directly on the object. For example, mycharacter.remove();.

[edit] Global Objects

There are several objects that are globally available anywhere in your script.

[edit] Campaign() (function)

A function which returns the Campaign object. Since there is only one campaign, this global always points to the only campaign in the game. Useful for doing things like checking to see if an object is on the active page using Campaign().get("playerpageid").

[edit] state

The state variable is an object in the global scope which is accessible to all scripts running in a game. You can access the state object from any function or callback at any time just by using the global variable named state. Additionally, the state object is persisted between executions of the Sandbox, so you can use it to store information you want to have in future runs of your script.

Note: You should use the state object to store information that is only needed by the API, since it is not sent to player computers and does not make your game file larger. Store values that are needed in-game in the Roll20 objects' properties.

[edit] Storable Types

The state object is only capable of persisting simple data types, as supported by the JSON standard.

Type Examples Description
Boolean true false The value true or false.
Number 123.5 10 1.23e20 Any number format supported by Javascript. Floating-Point or Integer.
String 'Hello Fantasy' "oh, and World" A standard string of text.
Array [ 1, 2, 3, 4 ] [ 'A','B','C'][1, 2, ['bob', 3], 10, 2.5] An ordered collection of any of the types, including other arrays.
Object { key: 1, value: 'roll20' } A simple key/value object with string keys and any of the types as a value, including other objects.

Warning: While functions will appear to work when stored in the state initially, they will disappear the first time the state is restored from persistence, such as on a sandbox restart.

  • Note: This includes Roll20 objects which you get from events or the functions findObjs(), getObj(), filterObjs(), createObj(), etc.

[edit] Important Reminders

The state object is shared between all of the scripts in a sandbox. To avoid breaking other scripts, it is important to follow a few simple guidelines:

  • Never assign directly to the root state object.
state = { break: 'all the things' };  // NEVER DO THIS!!!
  • Avoid using local variables named state in your scripts. While this will work, it will be confusing to later users of your scripts and could cause issues if the code is carelessly edited.
function turn(){
    var state = Campaign().get('turnorder');  // Bad Practice, Avoid it!
    // ...
}
  • Always place your properties beneath at least one namespace property. Be sure to use a sufficiently descriptive namespace property. Avoid names like script or settings. It's best to either use the name of your module or your own name or handle.
if( ! state.MyModuleNamespace ) {
    state.MyModuleNamespace = { module: 'my module', ok: 'this is fine!', count: 0 };
}
state.MyModuleNamespace.count++;

[edit] Example Usage

This is a working example that uses the state object appropriately.

on('ready',function() {
    "use strict";

    // Check if the namespaced property exists, creating it if it doesn't
    if( ! state.MyModuleNS ) {
        state.MyModuleNS = {
            version: 1.0,
            config: {
                color1: '#ff0000',
                color2: '#0000ff'
            },
            count: 0
        };
    }

    // Using the state properties to configure a message to the chat. 
    sendChat(
        'Test Module',
        '<span style="color: '+state.MyModuleNS.config.color1+';">'+
            'State test'+
        '</span> '+
        '<span style="color: '+state.MyModuleNS.config.color2+';">'+
            'Script v'+state.MyModuleNS.version+' started '+(++state.MyModuleNS.count)+' times!'+
        '</span>'
    );
});

[edit] Finding/Filtering Objects

The API provides several helper functions which can be used to find objects.

[edit] getObj(type, id)

This function gets a single object if pass in the _type of the object and the _id. It's best to use this function over the other find functions whenever possible, as its the only one that doesn't have to iterate through the entire collection of objects.

on("change:graphic:represents", function(obj) {
    if(obj.get("represents") != "") {
       var character = getObj("character", obj.get("represents"));
    }
});


[edit] findObjs(attrs)

Pass this function a list of attributes, and it will return all objects that match as an array. Note that this operates on all objects of all types across all pages -- so you probably want to include at least a filter for _type and _pageid if you're working with tabletop objects.

var currentPageGraphics = findObjs({                              
  _pageid: Campaign().get("playerpageid"),                              
  _type: "graphic",                          
});
_.each(currentPageGraphics, function(obj) {    
  //Do something with obj, which is in the current page and is a graphic.
});

You can also pass in an optional second argument which contains an object with a list of options, including:

  • caseInsensitive (true/false): If true, string properties will be compared without regard for the case of the string.


var targetTokens = findObjs({
    name: "target"
}, {caseInsensitive: true});
//Returns all tokens with a name of 'target', 'Target', 'TARGET', etc.

[edit] filterObjs(callback)

Will execute the provided callback function on each object, and if the callback returns true, the object will be included in the result array. Currently, it is inadvisable to use filterObjs() for most purposes – due to the fact that findObjs() has some built-in indexing for better executing speed, it is almost always better to use findObjs() to get objects of the desired type first, then filter them using the native .filter() method for arrays.

var results = filterObjs(function(obj) {    
  if(obj.get("left") < 200 && obj.get("top") < 200) return true;    
  else return false;
});
//Results is an array of all objects that are in the top-left corner of the tabletop.

[edit] getAllObjs()

Returns an array of all the objects in the Game (all types). Equivalent to calling filterObjs and just returning true for every object.


[edit] getAttrByName(character_id, attribute_name, value_type)

Gets the value of an attribute, using the default value from the character sheet if the attribute is not present. value_type is an optional parameter, which you can use to specify "current" or "max".

getAttrByName will only get the value of the attribute, not the attribute object itself. If you wish to reference properties of the attribute other than "current" or "max", or if you wish to change properties of the attribute, you must use one of the other functions above, such as findObjs.

For repeating sections, you can use the format repeating_section_$n_attribute, where n is the repeating row number (starting with zero). For example, repeating_spells_$2_name will return the value of name from the third row of repeating_spells.

You can achieve behavior equivalent to getAttrByNamewith the following:

// current and max are completely dependent on the attribute and game system
// in question; there is no function available for determining them automatically
function myGetAttrByName(character_id,
                         attribute_name,
                         attribute_default_current,
                         attribute_default_max,
                         value_type) {
    attribute_default_current = attribute_default_current || '';
    attribute_default_max = attribute_default_max || '';
    value_type = value_type || 'current';

    var attribute = findObjs({
        type: 'attribute',
        characterid: character_id,
        name: attribute_name
    }, {caseInsensitive: true})[0];
    if (!attribute) {
        attribute = createObj('attribute', {
            characterid: character_id,
            name: attribute_name,
            current: attribute_default_current,
            max: attribute_default_max
        });
    }

    if (value_type == 'max') {
        return attribute.get('max');
    } else {
        return attribute.get('current');
    }
}
