I'm trying to use the following script along with the joystick.js script provided by Unity. This script disables the joystick by dominating all touches. Any help appreciated.

var guiSpeedElement : Transform;

private var normalizedSpeed : float = 0.2;
private var euler : Vector3 = Vector3.zero;



function Awake () {
multiTouchEnabled=true; 

guiSpeedElement.position = new Vector3 (0, normalizedSpeed, 0);
}

function Update () {

    if (Input.touchCount>0){
    for (var evt : Touch in Input.touches)

    {
        if (evt.phase == TouchPhase.Moved)
        {
            normalizedSpeed = evt.position.y / Screen.height;
            guiSpeedElement.position = new Vector3 (0, normalizedSpeed, 0);
        }
    }
}
}
