I have a camera facing the ground and I want to pan up to look at a target object in the distance.
Currently, I achieve this with the following:
Vector3 dir = targetPoint - transform.position;
Quaternion lookRotation = Quaternion.LookRotation(dir);
Quaternion newRotation = Quaternion.RotateTowards(transform.rotation, lookRotation, rotationDamping * Time.deltaTime);
transform.rotation = newRotation;
The camera performs the rotation and ends up pointing at the target object correctly, but as the camera pans up it tilts to one side making my game world set at an angle to the viewer, which is pretty disorienting:
How can I constrain the camera angle some way so that the horizon is always flat to the camera?
Thanks!
