Перемещение куба с помощью контроллера Gear VR в Unity

Я пытаюсь создать приложение Gear VR с контроллером Gear VR и Oculus SDK. Я получил GazePointerRing для работы с префабом контроллера. В моем приложении есть сетка, которую я могу перемещать с помощью контроллера Gear VR. Он обнаруживает кубики, которые я поместил в сцену. Сейчас я хочу навести сетку на куб и удерживать кнопку на контроллере, чтобы куб прилип к моей модели контроллера и мог перемещаться, пока я не отпущу кнопку. Я искал в сценарии OVR Physics Raycaster, как я могу вызвать попадание raycast и ввести его в команду кнопки в операторе if. Но я не могу найти способ вызвать попадание лучей с объектом. Это код Oculus в скрипте OVR Physics Raycaster:
