[Newbie in js] "wait" and teleporting devices

Hello!

I've done 2 teleporting pillars. Entering "1teleport" telleports player to "2teleport" and its working well:

 var warptarget : Transform;
 
     function Update () {}
     function OnTriggerEnter (col : Collider) {
     if (col.gameObject.tag == "warp001")
     this.transform.position = warptarget.position;
     }

on 1teleport: collider/trigger with tag "warp1"

on script attached to FPScontroller: 2teleport is marked as warptarget

Everything is working ok. But ive tried to make a wey to go back. Ive done another script with tag "warp2" and done as above but I discovered, that trigger "warp2" and destination for second warp target, cant be in same pillars.

So, if Im right, I need to make it like "when script1 or script2 is activated, wait until FPScontroller leaves triggers warp1 or warp2".

Am I right? And how to do that? :)
