Question by Rossos · Jun 24, 2014 at 07:28 PM ·

Problem with Execution Order

Hi guys I have a little problem. I have C# script called "Item" and I wanted to add him to the Execution Order but all other scripts showed up in list but not this one. I don't really know how fix it. (sorry for my english ;p)

Script:

 using UnityEngine;
 using System.Collections;
 
 [System.Serializable]
 public class Item {
     public string itemName;
     public int itemID;
     public string itemDesc;
     public Texture2D itemIcon;
     public int itemPower;
     public int itemSpeed;
     public ItemType itemType;
         
     public enum ItemType {
         Weapon,
         Consumable,
         Quest
     }
 
     public Item(string name, int id, string desc, int power, int speed, ItemType type)
     {
         itemName = name;
         itemID = id;
         itemDesc = desc;
         itemIcon = Resources.Load<Texture2D>("Item Icons/" + name);
         itemPower = power;
         itemSpeed = speed;
         itemType = type;
     }
 
 
 }

Your Item class isn't a $$anonymous$$onoBehaviour, so it doesn't "execute" as far as Unity's concerned. Is there some other script that's creating, updating, or destroying it? That's the script you'll want to set an execution order for.

I have three scripts - item, iventory and item databse. $$anonymous$$y inventory script is adding items to the inventory from the item database before they exist. So I have to add an item script to execution order on the first place because item database requires item to exist other way I'll get an error again. I hope that's what you mean xD $$anonymous$$y english is awful :D In the tutorial script looked almost identical and has been added with no problems..

Sounds like you need the database to create an item before it's accessed.

I see two solutions:

  • $$anonymous$$ake sure the database always creates an item before you ever attempt an access. This might involve an execution order.

  • $$anonymous$$odify the database so that it can create an item on demand, the first time it's accessed ("lazy instantiation"). This involves some code changes.
