Key and Door Tutorial Help?

Question

I was following a tutorial to make a key open a door to lead to the end of the game/the next level, but I can't physically pick up the key to an inventory and therefore I can't open the door. These are the scripts I'm using:

Door Script -

 var Key : GameObject;
 private var Door = false;
 
 function Start () 
 {
 
 }
 
 function Update () 
 {
     if (Input.GetKeyDown(KeyCode.E) && Door == true && Key.active == false)
     {
     Application.LoadLevel("NextLevel");
     }
 }
 
 function OnTriggerEnter (theCollider : Collider)
 {
     if (theCollider.tag == "Player")
     {
         Door = true;
     }
 }
 
 function OnTriggerExit (theCollider : Collider)
 {
     if (theCollider.tag == "Player")
     {
         Door = false;
     }
 }

Key Script -

 var TheKey : GameObject;
 private var playerNextToKey = false;
 
 function Update () 
 {
      if (Input.GetKeyDown(KeyCode.E) && playerNextToKey == true)
     {
     TheKey.active = false;
     }
 }
 
 function OnTriggerEnter (theCollider : Collider)
 {
     if (theCollider.tag == "Player")
     {
         playerNextToKey = true;
     }
 }
 
 function OnTriggerExit (theCollider : Collider)
 {
     if (theCollider.tag == "Player")
     {
         playerNextToKey = false;
     }
 }

Please can someone tell me how to physically pick up the key so that I can then unlock the door to either end the game (preferably) or lead to the next level.

HELP NEEDED ASAP, THIS GAME HAS A DEADLINE!

The script looks fine. I think you need to change the tag on your main character object to "Player".

If you just need an easy and fast way to make an inventory of keys, create an inventory script like so

 public class Inventory
 {
     List<Key> keys=new blabla;
     public bool hasKey(Key key)
     {
         // And here just check if the received key( from the 
         // door or something else) is in the inventory.
         return true;
     }
 }

then in the door you can make something like :

 void Update()
 {
      if(Input.GetKeyDown(KeyCode.E)&& Door)
      {

          //get a reference to the player that has the inventory, and then

          if(player.GetComponent<Inventory>().haskey(key))
          {
              //load level
          }
      }
       
 }

this is the fast and easy way, i wouldn't do it this way but since you are in a hurry ,this will do i suppose
