Unity Engine
1

Hello,
So i got ScriptableObject Chest and when i use it, it reference to original Chest asset so when i got 2 same chests in inventory it shows exacly same numbers and if i open one of them it’s destroying both. How can i copy my Chest in runtime and reference to a copy?

using System.Collections.Generic;
using UnityEngine;
using Random = UnityEngine.Random;

[CreateAssetMenu(menuName = "Items/ChestOfItems")]
public class Chest : Item
{
    public Reward Reward;
    public int howManyOpens;
    [SerializeField] private int howManyItemsDrop;

    public override void OnValidate()
    {
        base.OnValidate();

        for (int i = 0; i < Reward.Items.Count; i++)
        {
            Reward.Items[i].dropChance = 100 / Reward.Items.Count;
        }
    }


    public void Open(Character character)
    {
        howManyItemsDrop = Random.Range(Reward.minItemsToDrop, Reward.maxItemsToDrop);
        if (character.inventory.FreeSpaces() >= howManyItemsDrop)
        {
            character.AddExp(Reward.experience);
            character.AddCurrency(Reward.currency);

            for (int i = 0; i < howManyOpens; i++)
            {
                List<ItemDropChance> items = new List<ItemDropChance>(Reward.Items);

                int roll = Random.Range(0, 101);
                Debug.Log(roll);
                int itemChances = 0;
               
                for (int j = 0; j < items.Count; j++)
                {
                    itemChances += items[j].dropChance;
                    if (roll <= itemChances)
                    {
                        character.inventory.AddItem(items[j].item.GetCopy());
                        Debug.Log("Copied items lenght: " + items.Count);
                        items.RemoveAt(j);
                        break;
                    }
                }
            }
            howManyOpens--;
        }
    }

    public bool IsOpened()
    {
        return howManyOpens <= 0;
    }

    public override string GetDescription()
    {
        sb.Clear();
        sb.Append("Opens left: " + howManyOpens);
        sb.AppendLine();
        sb.Append("Contains / Chance");
        for (int i = 0; i < Reward.Items.Count; i++)
        {
            sb.AppendLine();
            sb.Append(Reward.Items[i].item.ItemName + " / " + Reward.Items[i].dropChance +"%");
        }

        return sb.ToString();
    }
   
    public override void Destroy()
    {
        Destroy(this);
    }
}

Ok i got it, just added code below. Is my solution ok? Or should i do that other way?

public override Item GetCopy()
    {
         Chest inv = ScriptableObject.CreateInstance<Chest>();
         inv.buyPrize = buyPrize;
         inv.sellPrize = sellPrize;
         inv.ItemName = ItemName;
         inv.ItemLvlRequirment = ItemLvlRequirment;
         inv.ItemPlus = ItemPlus;
         inv.MaximumStacks = MaximumStacks;
         inv.Icon = Icon;
         inv.Reward = Reward;
         inv.howManyOpens = howManyOpens;
         return inv;
    }
