Enemy AI Range Detection

  var target : Transform;  //the player
     var speed : float = 10;  // the speed
     var controller:CharacterController;
     var aiDetectinRange : float 6;
 
     function Start(){
         controller = gameObject.GetComponent(CharacterController);
     }
     function Update(){
         transform.LookAt(target);  // the NPC looks at the player
         // Here you access the Character Controller component and move your NPC with SimpleMove() giving the speed and the direction(forward).
         //As the NPC is looking at you, forward is in your direction.
 
         // distance between the current object and the player, if within the distance then move
         if( Vect3.Distance(target.transorm.position,transform.position) < aiDetectionRange) )
             controller.SimpleMove(speed*transform.forward);
  
       }
     }

This didnt work, the enemy stays in one spot, even when Im right in front of its face

aiDetectinRange is spelled wrong. You check against aiDetectionRange, which if you aren't using #pragma strict in the header of the script will dynamically be declared..

I also thought it was Vector3.Distance(a,b)? If Vect3.Distance works, cool.
