A spatial node representing a spatially tracked controller. This is a helper spatial node that is linked to the tracking of controllers. It also offers several handy pass throughs to the state of buttons and such on the controllers. Controllers are linked by their id. You can create controller nodes before the controllers are available. Say your game always uses two controllers (one for each hand) you can predefine the controllers with id 1 and 2 and they will become active as soon as the controllers are identified. If you expect additional controllers to be used you should react to the signals and add ARVRController nodes to your scene. The position of the controller node is automatically updated by the ARVR Server. This makes this node ideal to add child nodes to visualise the controller. If active, returns the name of the associated controller if provided by the AR/VR SDK used. Returns the hand holding this controller, if known. See TRACKER_* constants in [ARVRPositionalTracker]. Returns [code]true[/code] if the bound controller is active. ARVR systems attempt to track active controllers. Returns the value of the given axis for things like triggers, touchpads, etc. that are embedded into the controller. Returns the ID of the joystick object bound to this. Every controller tracked by the ARVR Server that has buttons and axis will also be registered as a joystick within Godot. This means that all the normal joystick tracking and input mapping will work for buttons and axis found on the AR/VR controllers. This ID is purely offered as information so you can link up the controller with its joystick entry. Returns [code]true[/code] if the button at index [code]button[/code] is pressed. The controller's id. The first controller that the [ARVRServer] detects will have id 1, the second id 2, the third id 3, etc. When a controller is turned off, it's slot is freed. This ensures controllers will keep the same id even when controllers with lower ids are turned off. The degree to which the tracker rumbles. Ranges from [code]0.0[/code] to [code]1.0[/code] with precision [code].01[/code]. If changed, updates [member ARVRPositionalTracker.rumble] accordingly. Emitted when a button on this controller is pressed. Emitted when a button on this controller is released.
