How do i access variables on other gameobjects through tags?

So i have a player and a lot of doors in my map.
I want it so when my player is near the door and left clicks on the door it plays the animation DoorOpen, waits 3 seconds, plays the animation DoorClose.

I have tagged all my doors "door" and given them the script DoorOpen.
And given my player a script called OpenObjects.

But when i start my game it doesn´t work "nothing happens".
Console says: The referenced script on this Behaviour is missing!

*DoorOpen* script attached to the Doors.

Code (JavaScript):

1. #pragma strict
2.  
3. static var playerLeftClick = false;
4. var theDoor : Transform;
5.  
6. function changeDoorState ()
7. {
8.     if (playerLeftClick == true)
9.     {
10.         theDoor.animation.CrossFade("DoorOpen");
11.         //theChest.audio.PlayOneShot();
12.         playerLeftClick = false;
13.         yield WaitForSeconds(3);
14.         theDoor.animation.CrossFade("DoorClose");
15.         //theChest.audio.PlayOneShot();
16.         playerLeftClick = true;
17.     }
18. }

*OpenObjects* attached to the player.

Code (JavaScript):

1. #pragma strict
2.  
3. var hit : RaycastHit;
4. var Reach : float = 2.0;
5. var RayHit : boolean;
6.  
7. private var drawGUI = false;
8.  
9. var doorOpen : DoorOpen;
10.  
11. function Start()
12. {
13.     var door = GameObject.FindWithTag("door");
14. }
15.  
16. function Update ()
17. {
18.     var fwd = transform.TransformDirection (Vector3.forward);
19.     Debug.DrawRay(transform.position, fwd * Reach, Color.red);
20.     if (Physics.Raycast (transform.position, fwd, hit, Reach) && hit.transform.tag == "door")
21.     {
22.         RayHit = true;
23.         drawGUI = true;
24.      }
25.     else
26.     {
27.     RayHit = false;
28.     drawGUI = false;
29.    
30.     }
31.  
32.     {
33.     if (drawGUI == true && Input.GetButtonDown("Fire1"))
34.     {
35.         DoorOpen.playerLeftClick = true;
36.     }
37.   }
38. }
39.  
40. function OnGUI ()
41. {
42.     if (drawGUI == true)
43.     {
44.         GUI.Box (Rect (Screen.width*0.5-51, 200, 102, 22), "Click to open");
45.     }
46. }

 

You could also use the OnMouseDown() event, inside the door script, then when the user clicks on the door you can have it open/close as necessary. Hope this helps!

 

helped a lot, thanks!
