I am attempting to get an object to receive "heading" instructions from waypoints.

Here is the code I have written, however it does not work as I would anticipate I.E. doesn't make any apparent difference in the object's movement direction.

var movement = Vector3(.1, 0, 0);
private var waypoints : GameObject[] = GameObject.FindGameObjectsWithTag("WayPoint");
function Update () {
    transform.Translate(movement);
    for (var i = 0; i < waypoints.length; i++)
    {
        if (Vector3.Distance(transform.position, waypoints[i].transform.position) < 1)
        {
            var pointingDirection = waypoints[i].GetComponent(PointDirection);
            movement = pointingDirection.pointing;
        }
    }
}

The variable from the other object called "pointing" is a Vector3 giving an instruction similar to (-.1, 0, 0)

Thanks
