Camera Rotate to mouse position

Question

Hi guys, I need some help to make this code work, I'm making a point and click game ad I want that in some cases the camera act something like an human head (first person view) I want the camera to rotate where the mouse is looking at making it at the center of the screen, so far I've made this code:

 var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
     var hit : RaycastHit;
     if (Physics.Raycast (ray, hit, 1200)) {
         Debug.DrawLine (ray.origin, hit.point);
         camera_.LookAt(hit.point);
     }

The problem with this code is that the camera spins on itself because the mouse is always pointing to a new world position, how can I make the mouse to move smooth to the center?

Thanks for the help

    var targetRotation : Quaternion;  //Script variable
    var speed = 2.0;

    ...

    var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
    var hit : RaycastHit;
    if (Physics.Raycast (ray, hit, 1200)) {
        Debug.DrawLine (ray.origin, hit.point);
         targetRotation = Quaternion.LookRotation(hit.point - camera_.transform.position);

     }


    ...

    function LateUpdate() {
           transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, Time.deltaTime * speed);
    }

@whydoidoit this might be a noob question, but what if the ray doesn't hit anything? wouldn't the whole expression evaluate to false and none of the statement would be executed?

I could not solve this problem too, for my project rapidessay, I hope that I will be able to cope with that.
