Question by Juri · Feb 21, 2011 at 03:46 PM · ai

Raycast problems in my AI

So I have a short question... why is this Raycast not setting my var see to true?

var waypoint : Transform []; var speed : float = 20; private var currentWaypoint : int; var loop : boolean = true; var dist = 60; var hunt = 100; var player : Transform; var hit : RaycastHit; var see: boolean;

function Update () {

 if(currentWaypoint < waypoint.length){  
     var target : Vector3 = waypoint[currentWaypoint].position;
     var moveDirection : Vector3 = target - transform.position;
     var distFromPlayer : Vector3 = player.position-transform.position;  
     var velocity = rigidbody.velocity;

     if(moveDirection.magnitude<1){
     currentWaypoint++;
 }
 else if(distFromPlayer.magnitude < dist && see == true){
         velocity = Vector3.zero;
         target = player.position;
         velocity= (player.position-transform.position).normalized * speed;
         if((player.position - waypoint[currentWaypoint].position).magnitude >hunt){
             taget = waypoint[currentWaypoint].position;
             velocity = moveDirection.normalized * speed;
         }
     }
 else{
     velocity = moveDirection.normalized * speed;
 }
 }
 else{
     if(loop){
         currentWaypoint = 0;
     }
     else{
         velocity = Vector3.zero;
     }
     if(Physics.Raycast(transform.position , moveDirection, hit) &&hit == GameObject.FindWithTag("Player")){
                         see = true;
         }


     }

 rigidbody.velocity = velocity;
 transform.LookAt(target);


}
