使用Unity中的Gear VR控制器移动立方体

我正在尝试使用Gear VR控制器和Oculus SDK制作Gear VR应用程序 . 我让GazePointerRing与控制器预制件一起工作 . 我的应用程序中有一个十字线可见，我可以使用Gear VR控制器移动 . 它会检测我放置在场景中的立方体 . 我现在要做的是将十字线指向一个立方体，并在控制器上按住一个按钮，这样立方体就会粘在我的控制器模型上并可以移动直到我松开按钮 . 我一直在OVR Physics Raycaster脚本中搜索我如何调用光线投射命中并在if语句中的按钮命令中输入它 . 但我无法找到一种方法来调用带有物体的光线投射 . 这是OVR Physics Raycaster脚本中的Oculus代码：
