Accessing nodes in the scene tree Accessing nodes in the scene tree
================================= =================================
There are several ways to access nodes in the agent's scene tree (agent is the owner of :ref:`BTPlayer<class_BTPlayer>` node): There are several ways to access nodes in the agent's scene tree.
1. You can export a :ref:`BBNode<class_BBNode>` variable: **🛈 Note:** Agent is the owner of :ref:`BTPlayer<class_BTPlayer>` node.
With ``BBNode`` property
------------------------
.. code:: gdscript .. code:: gdscript
@export var cast: BBNode @export var cast_param: BBNode
func _tick(delta) -> Status: func _tick(delta) -> Status:
var node: ShapeCast3D = cast.get_value(agent, blackboard) var node: ShapeCast3D = cast_param.get_value(agent, blackboard)
2. You can export a ``NodePath``
With ``NodePath`` property
--------------------------
.. code:: gdscript .. code:: gdscript
@export var cast_path: NodePath @export var cast_path: NodePath
var _shape_cast: ShapeCast3D
func _setup() -> void: func _tick(delta) -> Status:
_shape_cast = agent.get_node(cast_path) var node: ShapeCast3D = agent.get_node(cast_path)
3. You can :ref:`create a blackboard variable<editing_plan>` in the editor with the type ``NodePath``
Using blackboard plan
---------------------
You can :ref:`create a blackboard variable<editing_plan>` in the editor with the type ``NodePath``
and point it to the proper node in the :ref:`BTPlayer<class_BTPlayer>` blackboard plan. and point it to the proper node in the :ref:`BTPlayer<class_BTPlayer>` blackboard plan.
