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]. 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]. 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].
