Roll20 Wiki

This is mean to serve as a comprehensive guide & starting point for figuring out how the q Text Chat, Dice Rolling, Macros and related things work and interact with each-other, and to list everything you can write/make appear in the q Text Chat.

This is both for Players/Gamemasters who are just writing their own custom rolls or macros to be used in their game, as well as those who build Character Sheets and are creating/editing Roll Buttons for their sheets.

Basics

The q Text Chat page shows the basic commands that can be used in the chat, such as /roll(or /r) for making simple rolls, /em for emoting text, /w for whispering to someone, and /gmroll(or /gr) for sending simple rolls to the GM.

You can write in the q Text Chat normal text without using any commands like /r.

Chat Commands

Dice Syntax

The Dice Reference page shows how the syntax for the Roll20 dice rolling works, and all the advanced alternatives you can use, such as rolling Fate Dice, or counting successes rather than the sum of the rolls.

Roll Table

If you have Roll Tables on your l Collections-tab, they can be used in rolls & macros.

Example1:

Let's assume there exist a roll table with the name fumble.

You can roll a table directly in the chat input, or in a macro, simply as 1t[fumble].

Example 2: To roll your "crit-failure" table two time, you would enter /roll 2t[crit-failure]. You can change 2 to whatever number you would like. However, this currently does not work with inline rolls.

You can also roll a table inline in chat or a macro by wrapping it in double square brackets like this [[1t[table-name]]]. Currently, any number beyond 1 does not display for the inline roll, the results are show on mouseover though.

Character Sheet Creation

Info and links to things that are only available for when you're Building Character Sheets. Consult the rest of the guide for general details.

Select Attributes for Sheet Roll - An advanced technique for creating a dynamic roll button on your sheet

Roll Button

See Button#Roll_Button.

Sheetworkers

With the info from Macros, fairly complex outputs to the q Text Chat can be made, but to be able to construct complex and dynamic results based on various factors on your character sheet, you will need to use JavaScript to write Sheet Worker Scripts that modify & construct your roll output dynamically.

Roll Template

When you create/edit a character sheet, you can make your own Roll Templates to make your roll output look like you want, and to do some conditional things such as only showing some sections in case of a critical roll in another sections.

See Roll_Templates#Creating_a_Roll_Template for more.

Roll_Templates#Helper_Functions describes what functions you can build into your sheets.
