Target touching enemy collision

Nevermind I fixed my own problem after 5 days For those who need reference, this is my final result

var player : Transform;

 enum TargetTouch 
 {
     none = 0,
     item = 1,
     enemy = 2
 }
 
 var targetState = TargetTouch.none;
 var changeArea : boolean = false;
 
 var canAttack : boolean = false;
 var canPickup : boolean = false;
 
 var otherObj : GameObject;
 var kill : boolean = false;
 
 function Update () 
 {
     var playDir = player.GetComponent("1P Attack");
     kill = false;
     
     if ( changeArea )
     {
         SetTarget();
     }
     
     if (canAttack)
     {
         if(Input.GetButtonDown("B"))
         {
             Destroy(otherObj);
         }
     }
     if (canPickup)
     {
         if(Input.GetButton("A"))
         {
             Destroy(otherObj);
         }
     }
     
     /*if (playDir.direction == 0) //no buttons
     {
         transform.position = player.transform.position;
     }*/
     if ( playDir.direction == 1) //north
     {
         transform.position.x = player.transform.position.x;
         transform.position.y = player.transform.position.y + 1.1;
     }
     if ( playDir.direction == 2) //east
     {
         transform.position.y = player.transform.position.y;
         transform.position.x = player.transform.position.x + 1.1;    
     }
     if ( playDir.direction == 3) //south
     {
         transform.position.x = player.transform.position.x;
         transform.position.y = player.transform.position.y - 1.1;
     }
     if ( playDir.direction == 4) //west
     {
         transform.position.y = player.transform.position.y;
         transform.position.x = player.transform.position.x - 1.1;
     }
 }
 function OnTriggerEnter ( other : Collider )    //Rigidbody or a Character Controller must be on the the target enemy for this to work 
 {
 
     if (other.tag == "enemy" )//&& Input.GetButton("B"))
     {
         otherObj = other.gameObject;
         changeArea = true;
         print ("Touching enemy");
         targetState = TargetTouch.enemy;
     }
     if(other.tag == "item" )//&& Input.GetButton("A"))
     {    
         otherObj = other.gameObject;
         changeArea = true;
         print("I picked up an item");
         targetState = TargetTouch.item;
     }
 }
