BTCooldown
==========

**Inherits:** :ref:`BTDecorator<class_BTDecorator>` **<** :ref:`BTTask<class_BTTask>` **<** :ref:`BT<class_BT>`

BT decorator that executes its child task only if :ref:`duration<class_BTCooldown_property_duration>` time has passed since the previous execution.

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

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

BTCooldown runs its child task only if :ref:`duration<class_BTCooldown_property_duration>` time has passed since the last successful child task execution. It will only consider successful executions unless :ref:`trigger_on_failure<class_BTCooldown_property_trigger_on_failure>` is set to ``true``.

Returns ``RUNNING``, if the child task results in ``RUNNING``.

Returns ``SUCCESS``, if the child task results in ``SUCCESS``, and triggers the cooldown timer.

Returns ``FAILURE``, if the child task results in ``FAILURE`` or if :ref:`duration<class_BTCooldown_property_duration>` time didn't pass since the previous execution.

Property Descriptions
---------------------

.. _class_BTCooldown_property_cooldown_state_var:

.. rst-class:: classref-property

``StringName`` **cooldown_state_var** = ``&""`` :ref:`🔗<class_BTCooldown_property_cooldown_state_var>`

.. rst-class:: classref-property-setget

- |void| **set_cooldown_state_var**\ (\ value\: ``StringName``\ )
- ``StringName`` **get_cooldown_state_var**\ (\ )

A boolean variable used to store the cooldown state in the :ref:`Blackboard<class_Blackboard>`. If left empty, the variable will be automatically generated and assigned.

If the variable's value is set to ``true``, it indicates that the cooldown is activated. This feature is useful for checking the cooldown state from other parts of the tree or sharing it among different sections of the :ref:`BehaviorTree<class_BehaviorTree>`.

.. _class_BTCooldown_property_duration:

.. rst-class:: classref-property

``float`` **duration** = ``10.0`` :ref:`🔗<class_BTCooldown_property_duration>`

.. rst-class:: classref-property-setget

- |void| **set_duration**\ (\ value\: ``float``\ )
- ``float`` **get_duration**\ (\ )

Time to wait before permitting another child's execution.

.. rst-class:: classref-item-separator

----

.. _class_BTCooldown_property_process_pause:

.. rst-class:: classref-property

``bool`` **process_pause** = ``false`` :ref:`🔗<class_BTCooldown_property_process_pause>`

.. rst-class:: classref-property-setget

- |void| **set_process_pause**\ (\ value\: ``bool``\ )
- ``bool`` **get_process_pause**\ (\ )

If ``true``, process cooldown when the ``SceneTree`` is paused.

.. rst-class:: classref-item-separator

----

.. _class_BTCooldown_property_start_cooled:

.. rst-class:: classref-property

``bool`` **start_cooled** = ``false`` :ref:`🔗<class_BTCooldown_property_start_cooled>`

.. rst-class:: classref-property-setget

- |void| **set_start_cooled**\ (\ value\: ``bool``\ )
- ``bool`` **get_start_cooled**\ (\ )

If ``true``, initiate a cooldown as if the child had been executed before the first BT tick.

.. rst-class:: classref-item-separator

----

.. _class_BTCooldown_property_trigger_on_failure:

.. rst-class:: classref-property

``bool`` **trigger_on_failure** = ``false`` :ref:`🔗<class_BTCooldown_property_trigger_on_failure>`

.. rst-class:: classref-property-setget

- |void| **set_trigger_on_failure**\ (\ value\: ``bool``\ )
- ``bool`` **get_trigger_on_failure**\ (\ )

If ``true``, the cooldown will be activated if the child task also returns ``FAILURE``. Otherwise, the cooldown will only be triggered when the child task returns ``SUCCESS``.
