RichTextEffect
==============
**Inherits:** :ref:`Resource<class_Resource>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`
A custom effect for use with :ref:`RichTextLabel<class_RichTextLabel>`.
Description
-----------
A custom effect for use with :ref:`RichTextLabel<class_RichTextLabel>`.
**Note:** For a ``RichTextEffect`` to be usable, a BBCode tag must be defined as a member variable called ``bbcode`` in the script.
::
# The RichTextEffect will be usable like this: `[example]Some text[/example]`
var bbcode = "example"
**Note:** As soon as a :ref:`RichTextLabel<class_RichTextLabel>` contains at least one ``RichTextEffect``, it will continuously process the effect unless the project is paused. This may impact battery life negatively.

Override this method to modify properties in ``char_fx``. The method must return ``true`` if the character could be transformed successfully. If the method returns ``false``, it will skip transformation to avoid displaying broken text.
