Promote player to GM

Promote someone to GM

The Creator or a GM can promote a Player to GM on the Game Settings-page. Hover your mouse over their icon, and select "Promote to GM". You should see that the player gets a blue "GM" on top of their icon.

A game can have any number of GMs, and multiple people can be logged in as a GM at the same time.

Rejoin as Player

The Creator or a GM can voluntarily disable their GM-status in a game, by in-game going to y My Settings-tab, and pressing the Rejoin as Player-button at the top.

By default, you always enter a game as a GM, if you are on it's main page, and either have to do the above each time, or you can right-click the Rejoin as Player-button and bookmark it.

You can also save the normal "enter game"-link as a bookmark, and add /?desiredrole=player to the end of the url.

https://app.roll20.net/editor/setcampaign/111111/?desiredrole=player

Using the bookmark you can you can enter the game directly as a player, avoiding accidentally spoiling yourself something before you have gone to the button.

API

This section is about a Roll20 feature exclusive to Pro-subscribers (and often to players in a Game created by a Pro-subscriber). If you'd like to use this feature, consider upgrading your account.

Some GM-only features can be indirectly granted to players through the use of different APIs:

• ChatSetAttr -- can be configured to allow players to evaluate or edit stats on characters they don't control, useful for automatically reducing enemy HP, or granting healing/ temp HP to allies.
• CharSheet -- A simple and easily customizable script allowing players to create their own character sheets, using the command !charsheet
• Door Knocker -- Enables players to reveal/hide Dynamic Lighting sections such as doors. The GM can change doors from between locked/unlocked to adjust which doors the players can open. Speeds up DL management for GM as well.
  • can be used for revealing hidden door, as well as making "windows"
• emas -- Provides player !emas and !as commands. This is equivalent to the /emas, which is GM-only
• MapChange -- has option to allow players to move between map pages, and GM can choose which pages are available/visible to them
• Observer^(Forum) -- handy way to add/remove players as "Observer", who can see & control all player characters.
• PublicSheet^(Forum) — create public, read-only versions of character sheets
• Roll20 Audio Master (aka. Roll20AM) -- API commands to manage the u Jukebox, GM can grant selective access to individual players/tracks
• Teleport -- provides a way for GMs or players to teleport tokens within,or between, map pages
• TokenMod -- For managing token properties with chat commands. Usually players have limited control of their token settings, apart from editing the three bubbles.
  • Includes setting that enables players to target tokens they don't control

There are also API that can be used to restrict players more that normal:

• DryErase^(Forum) – An API that can stop players from drawing on the map, deleting any drawing instantly.
• TokenLock – Allows GMs to lock/unlock the movement of all Player Tokens. - Useful for when you want to pause the situation and prevent players from accidentally moving forward.
• MapLock - similar to TokenMod, but can be used for locking down any individual graphic/token on the map, so even the GM can't accidentally move things.
  • Useful if you want players to have control over a token otherwise(see stats, edit/see name & notes), but stop it form being moved.
