Third Person Camera - Issues to clamp rotation

Hi,

I'm currently working on a third person camera and have issues to clamp the Y axis value correctly. My first implementation works to some extent but had some limits since I want to change the "lookAt" transform in multiple scripts.

 public Transform    lookAt,  
                     playerCamera;      

 public  float       mouseSpeed      = 1.5f;
 public  float       yAxisMin        = -60f;
 public  float       yAxisMax        = 60f;
 public  bool        invertedYAxis   = true;
 private float       mouseX,
                     mouseY;

   private void LateUpdate ()
     {
         if ( Input.GetAxisRaw( "Mouse ScrollWheel" ) != 0 )
             CameraZoom();
 
         if ( Input.GetMouseButton( 0 ) )
             CameraMove();
     }    
 
 private void CameraMove ()
     {
         mouseX += Input.GetAxis( "Mouse X" ) * mouseSpeed;
         mouseY += ( invertedYAxis ) ? Input.GetAxis( "Mouse Y" ) * -mouseSpeed :
                                       Input.GetAxis( "Mouse Y" ) * mouseSpeed;
 
         mouseY = Mathf.Clamp( mouseY, yAxisMin, yAxisMax );
 
         playerCamera.LookAt( lookAt );
         lookAt.localRotation = Quaternion.Euler( mouseY, mouseX, 0 );
     }

So what i was trying to do instead of adding the values to "mouseX+Y" and use them i tried to add the new values directly to the current rotation.

     private void CameraMove ()
     {
         mouseX = Input.GetAxis( "Mouse X" ) * mouseSpeed;
         mouseY = ( invertedYAxis ) ? Input.GetAxis( "Mouse Y" ) * -mouseSpeed :
                                       Input.GetAxis( "Mouse Y" ) * mouseSpeed;

         float clampedY = Mathf.Clamp( lookAt.localEulerAngles.x + mouseY, yAxisMin, yAxisMax );    

         playerCamera.LookAt( lookAt );
         lookAt.localRotation = Quaternion.Euler( clampedY, lookAt.localEulerAngles.y + mouseX, 0 );
     }

To my suprise this method actually worked, but just as long as I didn't try to clamp the values. When i did the moment I go under 0 degrees i get clamped to the "yAxisMax" value. I understand from searching in the forum that the issue is caused by using the "localEulerAngles" variable, but I havn't really found another way to access the current rotation and increment the change.

Should i just try to clamp with values that suits 360 degrees or is there a "nicer" way to handle this?

Thanks in advance!
