GameObject创建订单问题

Question

I'm currently working on an inventory system in Unity3D, and came upon a weird problem. I have created non-MonoBehaviour classes for my inventory system (in case that matters), so that I have an Inventory class which holds a list of Slot objects, which in turn holds a list of Item objects.

Then I added a component script to my "HudInventoryPanel", called "HudInventoryController", which looks like this:

using UnityEngine;
using System.Collections;

public class HudSlotController : MonoBehaviour {

    private InventoryController ic;

    // Use this for initialization
    void Start () {
        ic = GetComponent<InventoryController>();
    }

    // Update is called once per frame
    void Update () {
    }

}

However, inside the Start() method, the InventoryController (part of my Player) hasn't been created yet, and it seems to me like the gameobjects are created in alphabetical order...?

How should I deal with this problem?

Answer 1

You can specify script execution order in the project settings (Edit -> Project settings -> Script execution order), so use that to make sure your scripts are executed in the correct order. In addition to that, you can use the Awake() method as all Awake s are executed before any Start() method. Hope a combination of these helps you!

Answer 2

I solved this by creating an intermediate variable in my InventoryController script, plus creating a "manual" getter; https://gist.github.com/toreau/f7110f0eb266c3c12f1b

Not sure why I have to do it this way, though.
