Correct me if I’m wrong, but isn’t GameObject.SetActive supposed to be like this

GameObject.SetActive(true);

???

Try this:

 var Cena: GameObject;
 function OnTriggerEnter(otherObj: Collider){
     Debug.log("triggered"); // trigger works finally
     if (otherObj.tag == "Player"){
         Debug.log("Cena enabled"); // Cena got enabled, yay \o/
         Cena.SetActive(true);
     } 
     else {
         Debug.log("Cena disabled"); // Just to check it's not instantly disabled again
         Cena.SetActive(false);
     }
 }

Finally I don’t know your scene, but if you got a big trigger platform for example, OnTriggerStay would be come in handy.
