Problem with GetComponent and Destroy

Hello Community,

First at all I want to say that I like the Unity Engine very much, but now I've got a problem I don't know how to handle it clearly. I tried to find a solution with google but it didn't work.


My Game I want to make is a top down hack and slash. (I know there is this tutorial with burgzerg, but that couldn't answer my question neither)

Now I try to create a pick up and inventory system similar to diablo.
Like: I can see an item on the ground and when I walk over it I would have it in my left hand.

My idea was:
The Item has got a lot of information (like which weapon? Or the name of it.. damage...)
And when I got it. My equipment (weaponLeft) should get all information.
After that the Object should be destroyed.

My problem is:

If I don't destroy the weapon on the floor. Everything works fine. I can shoot or hit and I got all attributes of the weapon.
But what should I do with the weapon? It should disappear.

But when I destroy the object. It say that weaponLeft is null. But When I'm debugging

Code (csharp):

1. print(weaponLeft.getDamage());

It will find the value of my picked weapon.

So that's why I'm confused. What was my mistake?

The only thing what I thought is, that I can try it with a new instance like

Code (csharp):

1. WeaponAttributes newWeapon = new WeaponAttributes(content);

But that can't be the solution. It's only that weaponLeft is no longer a WeaponAttributes the rest is ok.




The code of the files:

Player.Pickup.cs

Code (csharp):

1.  
2.  
3. public class PlayerPickUp : MonoBehaviour {
4.  
5.     private PlayerEquipment equipment;  // all stuff which the player can carry
6.     private PlayerAttributes attributes;    // attributes like str, hp
7.  
8.    void Update() {
9.         equipment = GetComponent<PlayerEquipment>();
10.         attributes = GetComponent<PlayerAttributes>();
11.     }
12.  
13.     /**
14.      * If the player reaches an item on the floor
15.     */      
16.  
17.     void OnTriggerEnter(Collider item) {
18.  
19.         if (item.GetComponent<Item>()) {
20.  
21.             Item itemAttributes = item.GetComponent<Item>();
22.             itemAttributes.setOwner(this.gameObject);
23.             itemAttributes.setId(this.attributes.getId());
24.            
25.             switch (itemAttributes.getItemCategory()) {
26.                
27.                 case "weapon":
28.                     equipment.setWeaponLeft(itemAttributes.GetComponent<WeaponAttributes>());
29.                     break;
30.                
31.                 case "gold":
32.                    
33.                     break;
34.    
35.             }
36.    
37.             if (itemAttributes.getIsPickable()) {
38.                 equipment.setGotNewItem(true);
39.                 Destroy(item.gameObject);
40.             }
41.        
42.         }
43.            
44.     }
45.  
46. }
47.  
48. Equipment:
49.  
50. public class Equipment : MonoBehaviour {
51.  
52.    private WeaponAttributes weaponLeft;
53.   /*** other code
54.   */
55.  
56.  public void setWeaponLeft(WeaponAttributes value) {
57.     this.weaponLeft = value;
58.  }
59.  
60.  /** other code
61.  */
62.  
63.  
64.  

Thank you for your help. If something is not clear pls tell me.

Greetings
