BTState
=======

**Inherits:** :ref:`LimboState<class_LimboState>`

A state node for :ref:`LimboHSM<class_LimboHSM>` that hosts a :ref:`BehaviorTree<class_BehaviorTree>`.

.. rst-class:: classref-introduction-group

Description
-----------

BTState is a :ref:`LimboState<class_LimboState>` node that manages a :ref:`BehaviorTree<class_BehaviorTree>` to provide behavior logic for the state. It instantiates and runs the :ref:`BehaviorTree<class_BehaviorTree>` resource, dispatching a state machine event upon ``SUCCESS`` or ``FAILURE``. Event names are customizable through :ref:`success_event<class_BTState_property_success_event>` and :ref:`failure_event<class_BTState_property_failure_event>`. For further details on state machine events, see :ref:`LimboState.dispatch<class_LimboState_method_dispatch>`.
