Directional Light Rotation Script

Hello,

I am trying to have my directional light raise and lower based on the players movement/speed. If the player runs faster, the directional light rises dynamically and vice versa.

Here is the script I currently have attached to my character controller:

Code (csharp):

1.  
2. var deltaAngle : float = 1.0;
3.  
4. function Update () {
5.     // is the player trying to move?
6.     if (Mathf.Abs(Input.GetAxis("Vertical")) > 0) {
7.                 light.transform.Rotate(Vector3.up,deltaAngle * Time.deltaTime);
8.     }
9.     // do nothing if the player is neither accelerating nor decelerating
10. }
11.  

Can anyone edit this script or point me in the right direction toward getting the my Directional Light to dynamically rotate as the player moves?

Thanks!
