Storing Sub items in an item class?

I am trying to make a weapon system for my game where a Guns (which are considered items) can hold other items on them (such as attachments). Is this possible using the same Item class?

 

I mean I don't see why it wouldn't be possible.

 

This should be possible.

This is an example of what you may be looking for:

Code (CSharp):

1. public abstract class Item : ScriptableObject
2.  
3.  
4. {
5.     [SerializeField]
6.     private string name;
7.  
8.     [SerializeField]
9.     private int value;
10.  
11.     public string Name => name;
12.  
13.     public int Value => value;
14. }
15.  
16.  
17. public class Weapon : Item
18. {
19.  
20.     [SerializeField]
21.     private int basePower;
22.  
23.     [SerializeField]
24.     private WeaponAttachment[] attachments = new WeaponAttachment[4];
25.  
26.  
27.     public int Power
28.     {
29.         int totalPower = basePower;
30.        
31.         foreach(var attachment in attachments.Where(attachment => attachment))
32.         {
33.             totalPower += attachment.PowerBoost;
34.         }
35.  
36.         return totalPower;
37.     }
38.  
39.     public void Attach(WeaponAttachment newAttachment)
40.     {
41.         for (int i = 0; i < attachments.Length; i++)
42.         {
43.             if (attachments[i]) // true if attachment is not null
44.             {
45.                 continue;
46.             }
47.  
48.             attachments[i] = newAttachment;
49.             return;
50.         }
51.  
52.         throw new OutOfRangeException();
53.     }
54.  
55. }
56.  
57.  
58. public class WeaponAttachment : Item
59. {
60.     [SerializeField]
61.     private int powerBoost;
62.  
63.     public int PowerBoost => powerBoost;
64. }

 

Ok, but when I place this script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class ItemDatabase : MonoBehaviour
6. {
7.     public List<Item> gameItems = new List<Item>();
8. }
9.  

I cannot set the values of the items in the list manually. How to fix?

 

Make your own class system https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/abstract and use it like you want.
Search more about "class inheritance" in c# and you'll be able to do it by yourself.

 

You mean you can not set them in the inspector?

As long as the size of the list is not zero and you are trying to drag and drop objects that are an item or a GameObject with an Item component (if it inherits MonoBehaviour), you should be able to add that object to the list.
