# Camera global rotation clamping issue Unity3D

I have a problem, I'm making an smooth camera movement script, and I can't figure out how to clamp correctly camera rotation.

Actually, camera is a child of player object.

When WASD is pressed the player is rotated, but the camera doesn't follow this rotation because of the script.

            var mouseDelta = new Vector2(Input.GetAxisRaw("Mouse X"), Input.GetAxisRaw("Mouse Y"));

mouseDelta = Vector2.Scale(mouseDelta, CursorSensitivity); //new Vector2(CursorSensitivity.x * smoothing.x, CursorSensitivity.y * smoothing.y));

if (m_doSmooth)
{
_smoothMouse.x = Mathf.Lerp(_smoothMouse.x, mouseDelta.x, 1f / smoothing.x);
_smoothMouse.y = Mathf.Lerp(_smoothMouse.y, mouseDelta.y, 1f / smoothing.y);

// Find the absolute mouse movement value from point zero.
_mouseAbsolute += _smoothMouse;
}
else
_mouseAbsolute += mouseDelta;

if (clampInDegrees.x > 0)
_mouseAbsolute.x = Mathf.Clamp(_mouseAbsolute.x, -clampInDegrees.x, clampInDegrees.x);

if (clampInDegrees.y > 0)
_mouseAbsolute.y = Mathf.Clamp(_mouseAbsolute.y, -clampInDegrees.y, clampInDegrees.y);

Camera.transform.rotation = Quaternion.AngleAxis(-_mouseAbsolute.x, Vector3.up) //transform.InverseTransformDirection(Vector3.up))
* Quaternion.AngleAxis(_mouseAbsolute.y, Vector3.right);


Well, the problem is easy, the clamped rotation values are global, because we set Camera.transform.rotation instead of Camera.transform.localRotation.

And this happens: Link to video

The script clamps values according to player rotation.

So if we have a rotation (eulerAngle) on the player on the X axis of 90 degrees, and clamp value is from 90 to -90, the clamped rotation will be 0, 180, instead of -90, 90.

But if I change from rotation to localRotation this happens: Link to video

I also tried the following:

            Vector3 euler = Camera.transform.eulerAngles;

if (clampInDegrees.x > 0)
euler.x = ClampAngle(euler.x, -clampInDegrees.x, clampInDegrees.x);

if (clampInDegrees.x > 0)
euler.y = ClampAngle(euler.y, -clampInDegrees.y, clampInDegrees.y);

Camera.transform.eulerAngles = euler;


After setting localRotation... But this only make weird things. Like for example, when reaching the min clamp value at rotating the clamp returns the max clamp value.
