	<brief_description>
		A 3D node representing a spatially-tracked controller.
	</brief_description>
	<description>
		This is a helper 3D node that is linked to the tracking of controllers. It also offers several handy passthroughs 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. If your game always uses two controllers (one for each hand), you can predefine the controllers with ID 1 and 2; 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 XRController3D nodes to your scene.
		The position of the controller node is automatically updated by the [XRServer]. This makes this node ideal to add child nodes to visualize the controller.
		The current [XRInterface] defines the names of inputs. In the case of OpenXR, these are the names of actions in the current action set from the OpenXR action map.

				Returns a numeric value for the input with the given [param name]. This is used for triggers and grip sensors.
				[b]Note:[/b] The current [XRInterface] defines the [param name] for each input. In the case of OpenXR, these are the names of actions in the current action set.

			<return type="Variant" />
			<param index="0" name="name" type="StringName" />
			<description>
				Returns a [Variant] for the input with the given [param name]. This works for any input type, the variant will be typed according to the actions configuration.
				[b]Note:[/b] The current [XRInterface] defines the [param name] for each input. In the case of OpenXR, these are the names of actions in the current action set.
