So my delema is that I used the same scripts as the FPS tutorial and set them up just as it explains in the tutorial but my character moves to one waypoint and stays there. Thus not moving to the next waypoint like it should. Any thoughts or ideas for a fix?
Code on waypoints
static var waypoints = Array();
var connected = Array();
static var kLineOfSightCapsuleRadius = 0.25;
static function FindClosest (pos : Vector3) : AutoWayPoint {
// The closer two vectors, the larger the dot product will be.
var closest : AutoWayPoint;
var closestDistance = 100000.0;
for (var cur : AutoWayPoint in waypoints) {
var distance = Vector3.Distance(cur.transform.position, pos);
if (distance < closestDistance)
{
closestDistance = distance;
closest = cur;
}
}
return closest;
}
@ContextMenu ("Update Waypoints")
function UpdateWaypoints () {
RebuildWaypointList();

function Awake () {
RebuildWaypointList();
}

function OnDrawGizmos () {
Gizmos.DrawIcon (transform.position, "Waypoint.tif");
}
// Draw the waypoint lines only when you select one of the waypoints
function OnDrawGizmosSelected () {
if (waypoints.length == 0)
