OnMouseOver but for VR pointer, please help to start

Hello,
I’m starting at OCULUS_GO, and I need to call a scene with the control of a button in space, and, for the moment, it works with mouseOVER.
How can I convert this code to make it work by pointing to the oculus go control?
how should the script go
Thank you very much for any help.

public class button_call_scene : MonoBehaviour
{ 
      public void OnMouseOver()
     {
Application.LoadLevel("main_scene");
     }

}

.

I recommend that for absolute basic stuff like this you check out Unity’s VR tutorials. They explain how you can do this (not only with a Controller, but also with gaze - simply looking at things), and also provide some nice scripts. I believe there are even some nice free Unity-provided Projects in the asset store.

thanks a lot … i find this.and leave here if some beguner needs too.
thanks a lot
