		A tracked object.
	</brief_description>
	<description>
		An instance of this object represents a device that is tracked, such as a controller or anchor point. HMDs aren't represented here as they are handled internally.
		As controllers are turned on and the AR/VR interface detects them, instances of this object are automatically added to this list of active tracking objects accessible through the [XRServer].
		The [XRController3D] and [XRAnchor3D] both consume objects of this type and should be used in your project. The positional trackers are just under-the-hood objects that make this all work. These are mostly exposed so that GDNative-based interfaces can interact with them.

	<methods>
		<method name="get_joy_id" qualifiers="const">
			<return type="int">
			</return>
			<description>
				If this is a controller that is being tracked, the controller will also be represented by a joystick entry with this ID.
			</description>
		</method>
		<method name="get_mesh" qualifiers="const">
			<return type="Mesh">
			</return>
			<description>
				Returns the mesh related to a controller or anchor point if one is available.
			</description>
		</method>
		<method name="get_orientation" qualifiers="const">
			<return type="Basis">
			</return>
			<description>
				Returns the controller's orientation matrix.
			</description>

			<return type="StringName">
			</return>
			<description>
				Returns the controller or anchor point's name, if applicable.
			</description>
		</method>
		<method name="get_tracker_type" qualifiers="const">
			<return type="int" enum="XRServer.TrackerType">
			</return>
			<description>
				Returns the tracker's type, which will be one of the values from the [enum XRServer.TrackerType] enum.
			</description>
		</method>

			<return type="Transform">
			</return>
			<argument index="0" name="adjust_by_reference_frame" type="bool">
			</argument>
			<description>
				Returns the transform combining this device's orientation and position.
			</description>
		</method>
		<method name="is_tracking_orientation" qualifiers="const">
			<return type="bool">
			</return>
			<description>
				Returns [code]true[/code] if this device is tracking orientation.
			</description>
		</method>
		<method name="is_tracking_position" qualifiers="const">
			<return type="bool">
			</return>
			<description>
				Returns [code]true[/code] if this device is tracking position.
