[b]Note:[/b] For a [RichTextEffect] to be usable, a BBCode tag must be defined as a member variable called [code]bbcode[/code] in the script. [codeblocks] [gdscript skip-lint] # The RichTextEffect will be usable like this: `[example]Some text[/example]` var bbcode = "example" [/gdscript] [csharp skip-lint] // The RichTextEffect will be usable like this: `[example]Some text[/example]` string bbcode = "example"; [/csharp] [/codeblocks] [b]Note:[/b] As soon as a [RichTextLabel] contains at least one [RichTextEffect], it will continuously process the effect unless the project is paused. This may impact battery life negatively. $DOCS_URL/tutorials/ui/bbcode_in_richtextlabel.html https://github.com/Eoin-ONeill-Yokai/Godot-Rich-Text-Effect-Test-Project Override this method to modify properties in [param char_fx].
