◆ GetPosition()

static Vector3 TiltFive.Wand.GetPosition	(	ControllerIndex	controllerIndex = `ControllerIndex.Right`,
		ControllerPosition	controllerPosition = `ControllerPosition.Grip`,
		PlayerIndex	playerIndex = `PlayerIndex.One`
	)

static

Gets the position of the wand in world space.

Parameters

controllerIndex
controllerPosition
glassesHandle	The specified glasses. If null is provided, this uses the default glasses.

Returns: If the indicated wand is not connected, this returns the zero vector.
