	<description>
		A custom effect for use with [RichTextLabel].
		[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.
		[codeblock]
		# The RichTextEffect will be usable like this: `[example]Some text[/example]`
		var bbcode = "example"
		[/codeblock]
		[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.
