Player of [BehaviorTree] resources. [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). 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. Path to the node that will be used as the agent. Setting it after instantiation will have no effect. [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. 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 status] holds the status returned by the behavior tree. See [enum BT.Status]. Emitted when BTPlayer has finished the behavior tree update. Argument [param 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].
