Base class for all :ref:`BehaviorTree<class_BehaviorTree>` decorators. You can create your own decorators by extending the BTDecorator class.
A decorator is a task within a :ref:`BehaviorTree<class_BehaviorTree>` that alters the behavior of its child task. Decorators can have only one child task.
Decorators can be used to add conditions, limits, or other constraints to the execution of a task. Examples of :ref:`BehaviorTree<class_BehaviorTree>` decorators include :ref:`BTInvert<class_BTInvert>`, :ref:`BTRepeat<class_BTRepeat>`, and :ref:`BTCooldown<class_BTCooldown>`. The use of :ref:`BehaviorTree<class_BehaviorTree>` decorators can simplify the design and implementation of complex behaviors by adding additional logic to existing tasks.
