Class equality

Hey guys,

i am creating a simple inventory,
when i make one class B equal a class A, the class b will be always equal to the A

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4. [System.Serializable]
5. public class Item{
6.     public string itemName;
7.     public string itemId;
8.     public int amount;
9. }
10.  
11. public class BasicScript : MonoBehaviour {
12.     public Item item_a;
13.     public Item item_b;
14.     void Start () {
15.         item_a = new Item ();
16.         item_a.amount = 1;
17.         item_a.itemName = "DefaultName";
18.         item_a.itemId = "00000x";
19.         item_b = item_a;
20.     }
21.     void Update () {
22.         item_a.amount++;
23.  
24.         if(item_a.amount==item_b.amount)
25.         {
26.             Debug.LogError("Something is wrong");
27.         }
28.     }
29. }
30.  
31.  

someone know what are happening,

thanks in advance

 

You have stumbled upon the difference between a Class and a Struct! In short, assigning variables to classes copies the reference to that class, while assigning variables to structs copies the struct, giving it its own memory and reference.

Change the Item class to struct and you're off to go!
