Select button following Camera head rotation

I'm using this script to get a row of 3 buttons to follow with the camera/head movement.

Code (CSharp):

1. public class FollowCamRotation : MonoBehaviour {
2.     public GameObject cam;
3.     public float speed = 0.5f;
4.     private Vector3 v3Offset;
5.  
6.     // Use this for initialization
7.     void Start () {
8.         v3Offset = transform.position - cam.transform.position;
9.  
10.     }
11.    
12.     // Update is called once per frame
13.     void Update () {
14.         transform.position = cam.transform.position + v3Offset;
15.         transform.rotation  = Quaternion.Slerp (transform.rotation, cam.transform.rotation, speed * Time.deltaTime);
16.         transform.localEulerAngles = new Vector3(0, transform.localEulerAngles.y, 0);
17.     }
18.  
19. }

The set of buttons rotates fine but I can only gaze select the center button. The left and right buttons are hard to select because once the head/camera is moved the set of buttons follows to the center again.

Is there a way to get the set of buttons not to follow head movement in a certain range while near the camera center position so the left and right buttons can be selected?

 

I did this in my pack 360 Video Player, I spawn the menu when the player looks at it, and delete the menu when player looks away.

For a simple solution, try making a box collider which covers all the buttons.
- OnPointerEnter, set the parent of the menu to null.
- OnPointerExit, set the parent of the menu to the Main Camera.

 

Thanks for the info. Will give the parent solution a go.

EDIT: The box collider did the trick. Cheers.
