I have a problem with my script

I have a problem with my script, the problem is it makes me repeatedly Probelm to accessing a function:

I have a Key and a Door Object.
When you take the key of the value to be implemented in the Door.cs.

KeyObject.cs

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class KeyObject : MonoBehaviour {
5.  
6.     Door door;
7.  
8.     void OnCollisionEnter2D(Collision2D other)
9.     {
10.         if (other.gameObject.CompareTag("Player"))
11.         {
12.             door.GiveKey();
13.             Destroy(gameObject);
14.         }
15.     }
16. }
17.  

Door.cs

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Door : MonoBehaviour
5. {
6.     private bool Keys = false;
7.  
8.     void OnCollisionEnter2D(Collision2D other)
9.     {
10.         if (other.gameObject.CompareTag("Player"))
11.         {
12.             if (Keys == false)
13.             {
14.                 Debug.Log("Access DENIED");
15.             }
16.             else
17.             {
18.                 Destroy(gameObject);
19.             }
20.         }
21.     }
22.  
23.     public void GiveKey()
24.     {
25.         Keys = true;
26.     }
27. }
28.

OK, so your KeyObject contains a Door, but you don't assign it a value. You need to couple the KeyObject to a Door object somehow. Either make the Door object public and assign a GameObject with a Door script through the Inspector or find it somehow for example with GameObject.Find(). Once you have a GameObject you can access the Door script like this:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. public class KeyObject : MonoBehaviour {
4.     public GameObject doorToOpen;
5.     Door door;
6.  
7.    void Start() {
8.       door = doorToOpen.GetComponent<Door>();
9.    }
10.  
11.     void OnCollisionEnter2D(Collision2D other)
12.     {
13.         if (other.gameObject.CompareTag("Player"))
14.         {
15.             door.GiveKey();
16.             Destroy(gameObject);
17.         }
18.     }
19. }

 

Thanks very much. It works perfectly.
