When writing texts in text events or choices, you can utilize many systems to tweak the behaviour, content and styling of the texts.
📜 Content
BBCode
In Text events you can use BBCode tags, that allow you to style your text: from bold, italics and underlines to colors, fonts, images, and crazy wave effects. Learn more in the Godot docs: BBCode in RichTextLabel. If you need BBCode on the choice buttons, you will have to use custom choice buttons that use RichTextLabel to display their text!
Variables/Expressions
Anything in {curly brackets} will be considered an expression. It will be evaluated when the text is shown and the result will be inserted. This could be a simple dialogic variable or a variable on an autoload. Learn more on the Variables page.
Text modifiers
Text modifiers range from simple inserts like [br] (to insert a line break) to <random/selection> (selects a random option) or conditional texts [if {Expression} Show if true./Else show this.] (prints one of the text based on the result of the expression).
You can find a full list of the text modifiers here: Text Modifiers
Text Effects
Text effects look similar to bbcode, but usually have an effect that happens when the text-revealing reaches that point. That could be [pause=x] (pauses x seconds), [speed=x] (changes the speed of revealing), or [signal=x] (emits the Dialogic.text_signal with the argument x).
