Will this script work for a door that needs all 9 papers (keys to open).Like slenderman where you collect papers not keys and 9 of them to open 1 door.

 //Booleans:

 var IsOpen : boolean = false;
  
 var CanOpen : boolean = false;
  
 var NeedKey : boolean = true;
  
 //Audios:
  
 var Locked : AudioClip;
  
 var Open : AudioClip;
  
 //Other:
  
 var Volume : float = 0.5;
  
 var KeyScript : GameObject;

 audio.volume = Volume;
 }
  
 function Update () {

         Opening();
