Player of [BehaviorTree] resources. 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]). For an introduction to behavior trees, see [BehaviorTree]. Returns the behavior tree's last execution status. See [enum BT.Status]. Returns the root task of the instantiated behavior tree. Resets the behavior tree's execution. Each running task will be aborted and the next tree execution will start anew. This method does not reset [Blackboard]. Executes the root task of the behavior tree instance if [member active] is [code]true[/code]. Call this method when [member update_mode] is set to [constant MANUAL]. When [member update_mode] is not [constant MANUAL], the [method update] will be called automatically. See [enum UpdateMode]. If [code]true[/code], the behavior tree will be executed during update. [BehaviorTree] resource to instantiate and execute at runtime. Holds data shared by the behavior tree tasks. See [Blackboard]. Stores and manages variables that will be used in constructing new [Blackboard] instances. If [code]true[/code], adds a performance monitor to "Debugger->Monitors" for each instance of this [BTPlayer] node. If [code]true[/code], any [NodePath] variables in the [Blackboard] are replaced with [Node] references when the tree is instantiated. References are retrieved by calling [method Node.get_node] on the agent instance (agent is the owner of the BTPlayer node). Determines when the behavior tree is executed. See [enum UpdateMode]. Emitted when the behavior tree has finished executing and returned [code]SUCCESS[/code] or [code]FAILURE[/code]. Argument [param p_status] holds the status returned by the behavior tree. See [enum BT.Status]. Emitted when BTPlayer has finished the behavior tree update. Argument [param p_status] holds the status returned by the behavior tree. See [enum BT.Status]. Execute behavior tree during the idle process. Execute behavior tree during the physics process. Behavior tree is executed manually by calling [method update].
