Teleport player facing gameobjects x direction

Hello I have my game set so that when the player enters a door the player then teleports to the transform position of and invisible cube. I want to figure out how to force the player to face in the same X direction as the invisible cube. Any ideas? Thanks.

 function Start () 
 {
    
     
 }
 
 function OnTriggerStay(Col : Collider)
     {
         if(Col.tag == "Player")
         {
             if(Input.GetKey(KeyCode.E))
             {
                 
                 col=Color(0,0,0,1);
                 fadeblack = false;                               
                 fPlayer.transform.position = nextRoom.position;
                 GetComponent.<AudioSource>().PlayOneShot(doorSound);
                 doorSoundPlay = true;
                 col=Color(0,0,0,1);
                 fadeblack = true;
                 yield WaitForSeconds (0.8);
                 fadeblack = false;
                 
             }
         }
     }
