Can't Get Camera to NOT Move Past Shoulders

0favorite


I am trying to get my camera to not rotate past both of the player's shoulders. When I try to make the camera not move past the right shoulders it works perfectly but when I try to make it not move past the left shoulders it doesn't go past 0* and it will reset back to 89*. I have no clue why it won't work I even tried making it all positive and doesn't get anywhere close to this. Can someone please help?

Code (CSharp):

1.    public Transform target;
2.    Vector3 cameraAngles = transform.rotation.eulerAngles;
3.    cameraAngles.z = 0;
4.    Vector3 targetAngles = target.transform.rotation.eulerAngles;
5.    targetAngles.z = 0;
6.  
7.    //Will not go past 0* it will revert back to 89*
8.    if (cameraAngles.y >= (targetAngles.y + 89))
9.    {
10.        cameraAngles.y = targetAngles.y + 89;
11.    }
12.  
13.    if (cameraAngles.y <= (targetAngles.y - 89))
14.    {
15.        cameraAngles.y = targetAngles.y - 89;
16.    }
17.  
18.    transform.eulerAngles = cameraAngles;
19.    transform.RotateAround(target.transform.position, Vector3.up, rotationY);
20.    transform.RotateAround(target.transform.position, Vector3.left, rotationX);
21.    transform.LookAt(target.transform.position);

 

Here's a previous post I've made on this subject: https://forum.unity.com/threads/pre...above-specific-angles-3d.541580/#post-3571384

 

Ok I understand that except that post is about vertically only. Making a first person camera also requires horizontally.

 

Literally the exact same principle applies. If you want to clamp the yaw, then clamp the yaw.
