How to force camera rotation?

Question

Very simple here, I know... But I think I'm lost.

I've coded a script to control my camera and here is what I do to handle mouse control:

 void LateUpdate() {
     
     if (camlock == false) {
         _x += Input.GetAxis("Mouse X") * xSpeed * 0.02f;
         _y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02f;
         
         Quaternion rotation = Quaternion.Euler(_y, _x, 0);
         
         _myTransform.rotation = rotation;
     }
 }

It works pretty fine. But when player will press a button I'd like to force the camera position and orientation. I've tried using:

     transform.rotation = Quaternion.LookRotation(my_new_rotation_vector3);

But the rotation is not good (due to the lateUpdate method computing _x and _y according to Input.GetAxis() I think).

Any idea on how I should do to force camera rotation? should I use quaternions? If yes how?

Thank you.

This will modify the current camera rotation by the mouse, allowing you to set another rotation. Drop your _x and _y variables.

  void LateUpdate() {
 
     if (camlock == false) {
        var rot = transform.rotation.eulerAngles;
        rot.x += Input.GetAxis("Mouse X") * xSpeed * 0.02f;
        rot.y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02f;
 
        _myTransform.rotation = Quaternion.Euler(rot);
     }

 }

Thanks. I'm a bit ashamed it was so obvious and I didn't think of it.

We all do that kind of thing, all the time :)
