Orbit Camera with Cursor Position

I’m using an input (Wiimote) that outputs mouse position, rather than direct movement.

Is there a way I can alter the orbit camera script so that direction it faces is controlled by mouse/cursor position as opposed to mouse movement.

Thanks

Managed to get it working with this:

var target : Transform;

var distance = 10.0;

var xDec;
var yDec;

var x;
var y;

function Update () {
xDec = (Input.mousePosition.x - Screen.width / 2) / Screen.width;
yDec = (Input.mousePosition.y - Screen.height / 2) / Screen.height;

x = xDec * 80;
y = yDec * -40;

var rotation = Quaternion.Euler(y, x, 0);
var position = rotation * Vector3(0.0, 0.0, -distance) + target.position;

transform.rotation = rotation;
transform.position = position;

}
