Community Scripts

  • Script Index


The API Script Index is a listing of community-contributed API scripts that are available for use on Roll20. If you're interested in contributing to the Roll20 API Community Scripts please visit the API GitHub Repository and follow the instructions in the README.md file at the bottom of the page.


Scripts available in the One-Click Install

Scripts By Category

General Purpose Scripts

If your script incorporates specific game system rules, consider listing the script under that game system instead of one of these general purpose categories.

Combat Scripts

Combat scripts assist in making combat flow more easily. This can mean anything from automatically handling initiative to automating exchanges between combatants.

  • Group Initiative -- Adds the selected tokens to the turn order after rolling their initiative + configurable data.
  • Critical -- Quick method of determining the outcome of a critical hit.
  • Fumbler -- Quick method of determining the outcome of a fumble.

Tokens - Conditions / Status / Health

Tokens are used to represent player characters as well as non-player characters. Naturally, both occasionally get punched around a bit. Scripts in this category deal with the changing conditions of tokens, often but not necessarily as a result of combat.

  • Flight -- Mark how high tokens are flying
  • Flip Tokens -- Flip graphics horizontally and/or vertically
  • Mark -- Places a numbered Marker under tokens, clears on turn change/close, and page change.
  • Marking Conditions -- Set status markers on targeted on individual tokens

Tokens - Movement, Rotation, and Size

Scripts which are triggered by or change the location of tokens should generally be placed in this category.

  • API Heart Beat -- Provides an API Heartbeat by setting the requesting player's color continuously.
  • Collision Detection -- Handles collisions between player-controlled tokens and a subset of path objects on the page
  • KABOOM -- Creates explosion effects that move tokens away from or towards a point.
  • It's a Trap -- Script for setting traps and detecting collisions with them at any point during movement.
  • Marching Order -- Makes tokens follow each other in some specified order.
  • Measure -- Measure distances between multiple tokens, both from the corners and the center.
  • Monster Hit Dice -- Set Monster hit points from hit dice on add, usually via drag from journal.
  • Move Lighting -- Move dynamic lighting polygon path objects between game layers.
  • Random Rotate -- Allows the GM to easily rotate all selected tokens to a random angle.
  • Token Lock -- Allows GMs to selectively lock the movement of Player Tokens.

Lighting and Revealing

Dynamic lighting is a subscriber feature that changes what parts of the map are visible to the players as they move their tokens around. The light-blocking walls are achieved by paths on the walls layer, and tokens are used as point light sources. Scripts which modify either the light emitted by tokens or the walls which block the light belong in this category.

  • DLEllipseDrawer -- Draw circles and ellipses on the dynamic lighting layer.
  • LightCrumbTrails -- Produces lit, shared-vision breadcrumbs behind character tokens. This allows them to see where they've been on maps with dynamic lighting.
  • One-Way Dynamic Lighting -- Allows you to set up dynamic lighting walls that allow you to see through one side, but not the other. (for Legacy DL)
  • Torch -- A simple script for giving lights to tokens and turning off and on dynamic lighting.
  • Walls -- Builds dynamic lighting walls with an exported SVG path file.
  • ShareVision -- Allows normal vision and darkvision to be shared.

Jukebox

The jukebox is a powerful tool for creating immersive gaming experiences. Make it even more powerful.

  • Roll20 Audio Master -- Comprehensive jukebox control script; play, stop, and loop tracks. Adjust volume of tracks. Create, edit, play, stop, loop, and shuffle playlists.

Characters - Equipment

Most game systems have some form of equipment to make characters better. While scripts dealing with that equipment may necessarily be system-specific, there are scripts which handle equipment in a more general fashion.

  • Ammo -- Provides inventory management for ammunition stored in an attribute of a character.

Characters - Attributes

Manipulate one or more characters' attributes. Anything that is system-specific should be placed in the system's category below; this section is for system-agnostic attribute manipulation.

  • Conditions -- Track attribute-modifying conditions.
  • ChatSetAttr -- Create, modify, and delete character attributes via chat commands or macros.
  • EasyExperience -- Make awarding experience easy and choose your experience progression.
  • Experience Tracker -- Automatic tracking of a Dungeons and Dragons 5e like experience system, aswell as level up announcement in chat. !xp handles experience and announces level up.

Generators

Content generation can extend the reach of your campaign while minimizing the GM's prep time.

  • CharSheet -- Allow players to create their own character sheets.
  • Dungeon Utils -- Generates random dungeons from wall and floor images.
  • namegen -- Generates random names of People, Towns/Cities, and Taverns
  • Terrain Generator -- Generate simple outdoor maps (forests, deserts, etc)

System

Scripts in this category are a bit more meta than the ones listed above. These scripts assist with Roll20 itself more than they assist the game you're playing.

  • Game Timer -- This is a simple script to court how long does player use the game room.
  • Duplicate a Character and Token -- Duplicate and add identifying number to Character and Token.
  • emas -- Provides player !emas and !as commands.
  • MapLock -- Provides locking of graphics to prevent moving/resizing/rotating them. Also highlighting.

  • TruePageCopy -- Duplicate page graphics by chat command, or with the Duplicate Page button.
  • Customizable Roll Listener -- Customizable responses to API or non API chat messages.

Game Specific Scripts

Scripts that deal with specific rules of a game system should be listed in a sub-heading here. If the appropriate game system is not listed, feel free to create the appropriate heading.

Utility Scripts

These scripts are generally not intended to be used alone, but are often instead required by some of the above scripts. Alone, these scripts will not do anything for your campaign, but rather they create functions to be used by other scripts.
