Types of Objects
There are different types of objects that are used throughout the Roll20 Mod feature. 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).

Campaign
Property | Default Value | Notes | |
---|---|---|---|
_id | "root" | A unique ID for this object. Globally unique across all objects in this game. Read-only. | |
_type | "campaign" | Can be used to identify the object type or search for the object — however, note that there is only one Campaign object, and it can be accessed via Campaign() . Read-only.
| |
turnorder | "" | A JSON string of the turn order. See below. | |
initiativepage | false | ID of the page used for the t Turn Tracker when the turn order window is open. When set to false , the turn order window closes.
| |
playerpageid | false | ID of the page the player bookmark is set to. Players see this page by default, unless overridden by playerspecificpages below. | |
playerspecificpages | false | An object (NOT JSON STRING) of the format: {"player1_id": "page_id", "player2_id": "page_id" ... } Any player set to a page in this object will override the playerpageid. | |
_journalfolder | "" | A JSON string which contains data about the folder structure of the game. Read-only. | |
_jukeboxfolder | "" | A JSON string which contains data about the jukebox playlist structure of the game. Read-only. | |
token_markers | "" | A stringified JSON array containing an object for each token marker currently in the game |
Turn Order
The turn order is a JSON string representing the current turn order listing seen on the t Turn Tracker. 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. You must include the Page ID in _pageid
property for each item in the turnorder
when added or edited.
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". "_pageid": Campaign().get("playerpageid") }, { "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. "_pageid": Campaign().get("playerpageid") } ]
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" _pageid: Campaign().get("playerpageid") }); Campaign().set("turnorder", JSON.stringify(turnorder));

Dynamic Lighting
Property | Description | Type |
---|---|---|
has_bright_light_vision | Toggles vision for the token. | Boolean |
has_night_vision | Toggles night vision for the token. | Boolean |
night_vision_distance | Sets the range of night vision for the token. | Integer |
emits_bright_light | Toggles bright light for the token. | Boolean |
bright_light_distance | Sets the range of the amount of bright light emitting from a token. | Integer |
emits_low_light | Toggles low light for the token. This would be useful for a torch or a source with a low amount of light. Use the booleans true to turn on or false to turn off. | Boolean |
dim_light_opacity | Sets the "opacity" of the dim light. Lower values provide dimmer light, higher values yield brighter dim light. Default on new graphics is 0.75. | Decimal from 0.0 to 1.0 |
low_light_distance | Sets the range of the amount of low light emitting from a token. When setting this value, you must include any Bright Light Distance you have set. The reason for this is because Low Light Distance is calculated from the center of the token. So if you have set Bright Light Distance to 10, and you would like an additional 10 feet of Low Light Distance, the value of low_light_distance must be 20. |
Integer |
light_sensitivity_multiplier | Multiplier on the effectiveness of light sources. A multiplier of 200 would allow the token to see twice as far as a token with a multiplier of 100, with the same light source. | Integer |
night_vision_effect | Changes the Night Vision Effect. Other options include Dimming and Nocturnal |
String |
has_limit_field_of_vision | Toggles limit field of vision for the token. | Boolean |
limit_field_of_vision_center | Sets the value for where the center of the field of vision starts. | Integer |
limit_field_of_vision_total | Set the value for the total size of the field of vision. | Integer |
has_limit_field_of_night_vision | Toggles limit field of night vision for the token. | Boolean |
limit_field_of_night_vision_center | Sets the value for where the center of the field of night vision starts. | Integer |
limit_field_of_night_vision_total | Set the value for the total size of the field of night vision. | Integer |
has_directional_bright_light | Toggles directional bright light for the token. | Boolean |
directional_bright_light_center | Sets the value for where the center of the field of bright light starts. | Integer |
directional_bright_light_total | Set the value for the total size of the field of bright light. | Integer |
has_directional_dim_light | Toggles directional low light for the token. | Boolean |
directional_dim_light_center | Sets the value for where the center of the field of low light starts. | Integer |
directional_dim_light_total | Set the value for the total size of the field of low light. | Integer |
lightColor | Sets color of light. (e.g. #FF0000 for red) |
hexadecimal |
Legacy Dynamic Lighting
Property | Default Value | Notes | |
---|---|---|---|
light_radius | "" | Dynamic lighting radius. | |
light_dimradius | "" | Start of dim light radius. If light_dimradius is the empty string, the token will emit bright light out to the light_radius distance. If light_dimradius has a value, the token will emit bright light out to the light_dimradius value, and dim light from there to the light_radius value.
| |
light_otherplayers | false | Show the token's light to all players. | |
light_hassight | false | The light has "sight" for controlling players for the purposes of the "Enforce Line of Sight" setting. | |
light_angle | "360" | Angle (in degrees) of the light's angle. For example, 180 means the light would show only for the front "half" of the "field of vision".
|
|
light_losangle | "360" | Angle (in degrees) of the field of vision of the graphic (assuming that light_hassight is set to true )
|
|
light_multiplier | "1" | Multiplier on the effectiveness of light sources. A multiplier of two would allow the token to see twice as far as a token with a multiplier of one, with the same light source. | |
adv_fow_view_distance | "" | The radius around a token where Advanced Fog of War is revealed. |
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.
The statusmarkers
property of the Graphic object is (still in 2021?) 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"
imgsrc and avatar property restrictions
While you can now edit the imgsrc
and avatar
(Character) 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, orhttps://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 justhttps://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: 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.

Working with Character Sheets
The Character Sheets 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.
More about editing character sheets and how they work: Building Character Sheets
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 Building Character Sheets documentation for more information on how they 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
.
Handout

All Players is represented by having 'all' in the list. |
Note: The API does not have access to the folder hierarchy. API created handouts will be placed at the root level.
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.
Setting the gmnotes does not update the object, only setting notes does - so while the presentation order is notes > gmnotes, it is better to reverse this update order so any notes updates are set asynchronously after any call to set gmnotes, which will update both visually.
Async/Await solution
Alternatively, you can use modern ES6 javascript Async/Await to streamline the getting of these properties. The below function can be added to any script to provide a quick way to access these properties.
/** * Gets the blob info from roll20 objects asynchronously * @param {string} prop - the property to get * @param {Roll20 Object} obj - the Roll20 object to get the prop from * @returns {Promise<string>} - The contents of the blob. */ const getNotes = function (prop,obj) { return new Promise((resolve, reject) => { obj.get(prop, (p) => { resolve(p); }); }); };
To use this function, you will need to write an Async function:
const myFunc = async (charObj) => { const charBio = await getNotes('bio',charObj); // Do something with the bio content };
You can use this function to get any of the async text values:
- bio and gmnotes on characters
- gmnotes and notes on handouts
Simply pass the property you want as the first argument and the object that you want to get it from as the second argument.

Example Usage
on('chat:message', function(msg) { if (msg.type === 'api' && msg.content === '!cw') { const currentPageID = Campaign().get('playerpageid'); const win = createObj('window', { x: 70, y: -70, pageid: currentPageID, path: { handle0: { x: -70, y: 0, }, handle1: { x: 35, y: 0, }, }, color: '#000000' }); } if (msg.type === 'api' && msg.content === '!mw') { const win = getObj('window', '-NG38yUgghBBoV8YR0y1'); win.set({ x: 240, y: -139 }); } if (msg.type === 'api' && msg.content === '!dw') { const win = getObj('window', '-NG38yUgghBBoV8YR0y1'); win.remove(); } });
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 }); });
Deleting Objects
object.remove()
You can delete existing game objects using the .remove()
function. The .remove() function works on 'graphic', 'text', 'path', 'character', 'ability', 'attribute', 'handout', 'rollabletable', 'tableitem', and 'macro' objects. You call the function directly on the object. For example, mycharacter.remove();
.
Removing Repeating Section Attributes
As noted above, attribute objects can be removed using this method. To remove items from a repeating section of a Character Sheet, you will need to collect the attributes for that section and remove them all.
function deleteRepeatingSectionRow(rowid, characterid) { const regex = new RegExp(`^repeating_.*?_${rowid}_.*?$`); const attrsInRow = filterObjs(function(obj) { if (obj.get('type') !== 'attribute' || obj.get('characterid') !== characterid) return false; return regex.test(obj.get('name')); }); _.each(attrsInRow, function (attribute) { attribute.remove(); }); }
Global Objects
There are several objects that are globally available anywhere in your script.
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")
.
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.
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.
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
orsettings
. 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++;
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>' ); });
Finding/Filtering Objects
The API provides several helper functions which can be used to find objects.
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")); } });
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.
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.
getAllObjs()
Returns an array of all the objects in the Game (all types). Equivalent to calling filterObjs and just returning true
for every object.
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(RowIndex) (starting with zero). For example, repeating_spells_$2_name
will return the value of name
from the third row of repeating_spells
.
Instead of RowIndex, RowID can be used instead for referencing(?)
You can achieve behavior equivalent to getAttrByName
with 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'); } }
