Variables
Variables let you display dynamic values in your overlay or chat bot. Unlike with Functions however you cannot add in any extra parameters.
The format for using variables is {{variable_name}}. There can be no spaces in-between the word and the curly brackets. Variables can be used inside Functions but not the other way around.
For overlays
When used in the text field of a Text Widget or similar, they will display their value and automatically refresh when the value changes.
