Description Description
----------- -----------
BTPlayer node is used for the instantiation and playback of :ref:`BehaviorTree<class_BehaviorTree>` resources at runtime. During instantiation, the behavior tree instance is initialized with a reference to the agent and the :ref:`blackboard<class_BTPlayer_property_blackboard>`. Agent is the owner of the BTPlayer node (see :ref:`Node.owner<class_Node_member_owner>`). **BTPlayer** node is used to instantiate and play :ref:`BehaviorTree<class_BehaviorTree>` resources at runtime. During initialization, the behavior tree instance is given references to the agent, the :ref:`blackboard<class_BTPlayer_property_blackboard>`, and the current scene root. The agent can be specified by the :ref:`agent_node<class_BTPlayer_property_agent_node>` property (defaults to the BTPlayer's parent node).
For an introduction to behavior trees, see :ref:`BehaviorTree<class_BehaviorTree>`. For an introduction to behavior trees, see :ref:`BehaviorTree<class_BehaviorTree>`.

BTPlayer node is used for the instantiation and playback of [BehaviorTree] resources at runtime. During instantiation, the behavior tree instance is initialized with a reference to the agent and the [member blackboard]. Agent is the owner of the BTPlayer node (see [member Node.owner]). [BTPlayer] node is used to instantiate and play [BehaviorTree] resources at runtime. During initialization, the behavior tree instance is given references to the agent, the [member blackboard], and the current scene root. The agent can be specified by the [member agent_node] property (defaults to the BTPlayer's parent node).
