"SendMessage SetSpeed has no receiver!" error. FPS tutorial AI. (Img)

Im' going to try this question once again.

Hey! Iv'e got a real strange problem here that i can't figure out at all. Help me out here!

So the problem is that iv'e got a couple of characters following a AI script (The one from the FPS tutorial), until they are selected, then you control them using the keyboard, then when deselected it follows the AI instead.

My intention is to make the character keep following the waypoints.

Iv'e made a small painting of my own below, the red it's route and where it stops, maybe it help... I get error "SendMessage SetSpeed has no receiver!", on line 53 in the script. (Marked it)

It stops right there, eaven if you remove the waypoints with blue above it, so it hasn't got something to do with them.

The code (AI): var speed = 3.0; var rotationSpeed = 5.0; var shootRange = 15.0; var attackRange = 30.0; var shootAngle = 4.0; var dontComeCloserRange = 5.0; var delayShootTime = 0.35; var pickNextWaypointDistance = 2.0; var target : Transform; //static var larsan = target; var objektnamn : GameObject; private var lastShot = -10.0;

 // Make sure there is always a character controller
 @script RequireComponent (CharacterController)
 
 //function Awake() {
 // target = transform;
 //}
 
 function Start () {
 if (!this.enabled) return;
 
     // Auto setup player as target through tags
     if (target == null && GameObject.FindWithTag("Player"))

         // - player is killed
