BTTask
======

**Inherits:** :ref:`BT<class_BT>`

**Inherited By:** :ref:`BTAction<class_BTAction>`, :ref:`BTComment<class_BTComment>`, :ref:`BTComposite<class_BTComposite>`, :ref:`BTCondition<class_BTCondition>`, :ref:`BTDecorator<class_BTDecorator>`

Base class for all :ref:`BehaviorTree<class_BehaviorTree>` tasks.

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

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

Base class for all :ref:`BehaviorTree<class_BehaviorTree>` tasks. A task is a basic building block in a :ref:`BehaviorTree<class_BehaviorTree>` that represents a specific behavior or control flow. Tasks are used to create complex behaviors by combining and nesting them in a hierarchy.

A task can be one of the following types: action, condition, composite, or decorator. Each type of task has its own corresponding subclass: :ref:`BTAction<class_BTAction>`, :ref:`BTCondition<class_BTCondition>`, :ref:`BTDecorator<class_BTDecorator>`, :ref:`BTComposite<class_BTComposite>`.

Tasks perform their work and return their status using the :ref:`_tick<class_BTTask_private_method__tick>` method. Status values are defined in :ref:`Status<enum_BT_Status>`. Tasks can be initialized using the :ref:`_setup<class_BTTask_private_method__setup>` method. See also :ref:`_enter<class_BTTask_private_method__enter>` & :ref:`_exit<class_BTTask_private_method__exit>`.

\ **Note:** Do not extend **BTTask** directly for your own tasks. Instead, extend one of the subtypes mentioned above.

It is called before :ref:`_tick<class_BTTask_private_method__tick>` in the execution order. This method is used when preparation is needed before main work begins, usually when it takes more than one tick to finish the task. See also :ref:`execute<class_BTTask_method_execute>`.

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

----

.. _class_BTTask_private_method__exit:

.. rst-class:: classref-method

|void| **_exit**\ (\ ) |virtual| :ref:`🔗<class_BTTask_private_method__exit>`

Called when task is "exited", i.e. after :ref:`_tick<class_BTTask_private_method__tick>` returns ``SUCCESS`` or ``FAILURE`` status. See also :ref:`execute<class_BTTask_method_execute>`.

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

----

.. _class_BTTask_private_method__generate_name:

.. rst-class:: classref-method

``String`` **_generate_name**\ (\ ) |virtual| |const| :ref:`🔗<class_BTTask_private_method__generate_name>`

Called to generate a display name for the task unless :ref:`custom_name<class_BTTask_property_custom_name>` is set. See :ref:`get_task_name<class_BTTask_method_get_task_name>`.

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

----

.. _class_BTTask_private_method__get_configuration_warnings:

.. rst-class:: classref-method

``PackedStringArray`` **_get_configuration_warnings**\ (\ ) |virtual| |const| :ref:`🔗<class_BTTask_private_method__get_configuration_warnings>`

The string returned by this method is shown as a warning message in the behavior tree editor. Any task script that overrides this method must include ``@tool`` annotation at the top of the file.

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

----

.. _class_BTTask_private_method__setup:

.. rst-class:: classref-method

|void| **_setup**\ (\ ) |virtual| :ref:`🔗<class_BTTask_private_method__setup>`

Called to initialize a task during initialization step. It is called only once before the task's first execution tick. This method allows you to set up any necessary state or configurations for the task before it begins executing.

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

----

.. _class_BTTask_private_method__tick:

.. rst-class:: classref-method

:ref:`Status<enum_BT_Status>` **_tick**\ (\ delta\: ``float``\ ) |virtual| :ref:`🔗<class_BTTask_private_method__tick>`

Called when task is "ticked", i.e. executed by :ref:`BTPlayer<class_BTPlayer>` or :ref:`BTState<class_BTState>` during an update.

Returns execution status as defined in :ref:`Status<enum_BT_Status>`.

\ **Note:** Tasks perform their main function by implementing this method.

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

----

.. _class_BTTask_method_abort:

.. rst-class:: classref-method

|void| **abort**\ (\ ) :ref:`🔗<class_BTTask_method_abort>`

Resets the task and its children recursively. If a task is in the ``RUNNING`` state, it is exited and its status is reset to ``FRESH``.

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

----

.. _class_BTTask_method_add_child:

.. rst-class:: classref-method

|void| **add_child**\ (\ task\: :ref:`BTTask<class_BTTask>`\ ) :ref:`🔗<class_BTTask_method_add_child>`

Adds a child task. The ``task`` is placed at the end of the children list.

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

----

.. _class_BTTask_method_add_child_at_index:

.. rst-class:: classref-method

|void| **add_child_at_index**\ (\ task\: :ref:`BTTask<class_BTTask>`, idx\: ``int``\ ) :ref:`🔗<class_BTTask_method_add_child_at_index>`

Adds a child task. The ``task`` is placed at ``idx`` position in the children list.

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

----

.. _class_BTTask_method_clone:

.. rst-class:: classref-method

:ref:`BTTask<class_BTTask>` **clone**\ (\ ) |const| :ref:`🔗<class_BTTask_method_clone>`

Duplicates the task and its children, copying the exported members. Sub-resources are shared for efficiency, except for :ref:`BBParam<class_BBParam>` subtypes, which are always copied. Used by the editor to instantiate :ref:`BehaviorTree<class_BehaviorTree>` and copy-paste tasks.

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

----

.. _class_BTTask_method_editor_get_behavior_tree:

.. rst-class:: classref-method

:ref:`BehaviorTree<class_BehaviorTree>` **editor_get_behavior_tree**\ (\ ) :ref:`🔗<class_BTTask_method_editor_get_behavior_tree>`

Returns the behavior tree that owns this task. This is only available in the editor.

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

----

.. _class_BTTask_method_execute:

.. rst-class:: classref-method

:ref:`Status<enum_BT_Status>` **execute**\ (\ delta\: ``float``\ ) :ref:`🔗<class_BTTask_method_execute>`

Performs task's execution. The execution follows a specific sequence:

- If task's current :ref:`status<class_BTTask_property_status>` is not ``RUNNING``, the :ref:`_enter<class_BTTask_private_method__enter>` method is called first.

- Next, the :ref:`_tick<class_BTTask_private_method__tick>` method is called next to perform the task's work.

- If the :ref:`_tick<class_BTTask_private_method__tick>` method returns ``SUCCESS`` or ``FAILURE`` status, the :ref:`_exit<class_BTTask_private_method__exit>` method will be called next as part of the execution cleanup.

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

----

.. _class_BTTask_method_get_index:

.. rst-class:: classref-method

``int`` **get_index**\ (\ ) |const| :ref:`🔗<class_BTTask_method_get_index>`

Returns the task's position in the behavior tree branch. Returns ``-1`` if the task doesn't belong to a task tree, i.e. doesn't have a parent.

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

----

.. _class_BTTask_method_get_parent:

.. rst-class:: classref-method

:ref:`BTTask<class_BTTask>` **get_parent**\ (\ ) |const| :ref:`🔗<class_BTTask_method_get_parent>`

Returns the task's parent.

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

----

.. _class_BTTask_method_get_root:

.. rst-class:: classref-method

:ref:`BTTask<class_BTTask>` **get_root**\ (\ ) |const| :ref:`🔗<class_BTTask_method_get_root>`

Returns the root task of the behavior tree.

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

----

.. _class_BTTask_method_get_task_name:

.. rst-class:: classref-method

``String`` **get_task_name**\ (\ ) :ref:`🔗<class_BTTask_method_get_task_name>`

The string returned by this method is used to represent the task in the editor.

Method :ref:`_generate_name<class_BTTask_private_method__generate_name>` is called to generate a display name for the task unless :ref:`custom_name<class_BTTask_property_custom_name>` is set.

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

----

.. _class_BTTask_method_has_child:

.. rst-class:: classref-method

``bool`` **has_child**\ (\ task\: :ref:`BTTask<class_BTTask>`\ ) |const| :ref:`🔗<class_BTTask_method_has_child>`

Returns ``true`` if ``task`` is a child of this task.

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

.. _class_BTTask_method_initialize:

.. rst-class:: classref-method

|void| **initialize**\ (\ agent\: ``Node``, blackboard\: :ref:`Blackboard<class_Blackboard>`, scene_root\: ``Node``\ ) :ref:`🔗<class_BTTask_method_initialize>`

Initilizes the task. Assigns :ref:`agent<class_BTTask_property_agent>` and :ref:`blackboard<class_BTTask_property_blackboard>`, and calls :ref:`_setup<class_BTTask_private_method__setup>` for the task and its children.

The method is called recursively for each child task. ``scene_root`` should be the root node of the scene the behavior tree is used in (e.g., the owner of the node that contains the behavior tree).

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

----

.. _class_BTTask_method_is_descendant_of:

.. rst-class:: classref-method

``bool`` **is_descendant_of**\ (\ task\: :ref:`BTTask<class_BTTask>`\ ) |const| :ref:`🔗<class_BTTask_method_is_descendant_of>`

Returns ``true`` if this task is a descendant of ``task``. In other words, this task must be a child of ``task`` or one of its children or grandchildren.

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

----

.. _class_BTTask_method_is_root:

.. rst-class:: classref-method

``bool`` **is_root**\ (\ ) |const| :ref:`🔗<class_BTTask_method_is_root>`

Returns ``true`` if this task is the root task of its behavior tree. A behavior tree can have only one root task.

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

----

.. _class_BTTask_method_next_sibling:

.. rst-class:: classref-method

:ref:`BTTask<class_BTTask>` **next_sibling**\ (\ ) |const| :ref:`🔗<class_BTTask_method_next_sibling>`

Returns the next task after this task in the parent's children list.

Returns ``null`` if this task has no parent or it is the last child in the parent's children list.

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

----

.. _class_BTTask_method_print_tree:

.. rst-class:: classref-method

|void| **print_tree**\ (\ initial_tabs\: ``int`` = 0\ ) :ref:`🔗<class_BTTask_method_print_tree>`

Prints the subtree that starts with this task to the console.
