Sure enough, these are the 3 directions the camera sees. The camera is moved back and up and angled down at 60 degrees. so it makes sense that only left right and forward are snapping. However, I have no idea why they are snapping in the first place. Heres my code:
Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
RaycastHit hit;
if (Physics.Raycast (ray, out hit, 50, rayMask))
{
Vector3 point = new Vector3 (hit.point.x, transform.position.y, hit.point.z);
transform.LookAt (point);
}
So basically when I rotate a certain amount, it rotates another 20 or so degrees in a “snappy” fashion. its only when I look left right and at the camera. I am sure only the plane is in the cast mask.
