Signals
-------

.. _class_BTInstance_signal_freed:

.. rst-class:: classref-signal

**freed**\ (\ ) :ref:`🔗<class_BTInstance_signal_freed>`

Emitted when the behavior tree instance is freed. Used by debugger to unregister.

----

.. _class_BTInstance_signal_updated:

.. rst-class:: classref-signal

**updated**\ (\ status\: ``int``\ ) :ref:`🔗<class_BTInstance_signal_updated>`

Emitted when the behavior tree instance has finished updating.

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

.. _class_BTInstance_property_monitor_performance:

.. rst-class:: classref-property

``bool`` **monitor_performance** = ``false`` :ref:`🔗<class_BTInstance_property_monitor_performance>`

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

- |void| **set_monitor_performance**\ (\ value\: ``bool``\ )
- ``bool`` **get_monitor_performance**\ (\ )

If ``true``, adds a performance monitor for this instance to "Debugger->Monitors" in the editor.

.. rst-class:: classref-method

:ref:`Blackboard<class_Blackboard>` **get_blackboard**\ (\ ) |const| :ref:`🔗<class_BTInstance_method_get_blackboard>`

Returns the blackboard of the behavior tree instance.

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

----

.. _class_BTInstance_method_get_last_status:

.. rst-class:: classref-method

:ref:`Status<enum_BT_Status>` **get_last_status**\ (\ ) |const| :ref:`🔗<class_BTInstance_method_get_last_status>`

Returns the execution status of the last update.

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

----

.. _class_BTInstance_method_get_owner_node:

.. rst-class:: classref-method

``Node`` **get_owner_node**\ (\ ) |const| :ref:`🔗<class_BTInstance_method_get_owner_node>`

Returns the scene ``Node`` that owns this behavior tree instance.

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

----

.. _class_BTInstance_method_get_root_task:

.. rst-class:: classref-method

:ref:`BTTask<class_BTTask>` **get_root_task**\ (\ ) |const| :ref:`🔗<class_BTInstance_method_get_root_task>`

Returns the root task of the behavior tree instance.

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

----

.. _class_BTInstance_method_get_source_bt_path:

.. rst-class:: classref-method

``String`` **get_source_bt_path**\ (\ ) |const| :ref:`🔗<class_BTInstance_method_get_source_bt_path>`

Returns the file path to the behavior tree resource that was used to create this instance.

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

----

.. _class_BTInstance_method_is_instance_valid:

.. rst-class:: classref-method

``bool`` **is_instance_valid**\ (\ ) |const| :ref:`🔗<class_BTInstance_method_is_instance_valid>`

Returns ``true`` if the behavior tree instance is properly initialized and can be used.

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

----

.. _class_BTInstance_method_register_with_debugger:

.. rst-class:: classref-method

|void| **register_with_debugger**\ (\ ) :ref:`🔗<class_BTInstance_method_register_with_debugger>`

Registers the behavior tree instance with the debugger.

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

----

.. _class_BTInstance_method_unregister_with_debugger:

.. rst-class:: classref-method

|void| **unregister_with_debugger**\ (\ ) :ref:`🔗<class_BTInstance_method_unregister_with_debugger>`

Unregisters the behavior tree instance from the debugger. This is typically not necessary, as the debugger will automatically unregister the instance when it is freed.

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

----

.. _class_BTInstance_method_update:

.. rst-class:: classref-method

:ref:`Status<enum_BT_Status>` **update**\ (\ delta\: ``float``\ ) :ref:`🔗<class_BTInstance_method_update>`

Ticks the behavior tree instance and returns its status.
