Keeping object between edit and play modes.

Questions & Answers
1

I have an object with a multi-dimensional array of game objects that is initialized and filled in a function called from a custom inspector during edit mode. As soon as I press play the object is destroyed and rebuilt, which makes the array uninitialized/empty again.

I call 'DontDestroyOnLoad(this.gameObject)' in the object's awake function, but this doesn't seem to be doing anything. How can I preserve this array between edit and play modes? Thanks.

Edit: Here is the initialization for the array I'm trying to keep around. The 'fillArray()' function is called on a button press from my custom inspector. I noticed no difference after adding [System.Serializable] and [SerializeField]

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

[System.Serializable]
public class ArrayTest : MonoBehaviour
{
    //Array size variables
    int
        iLength,
        iWidth,
        iHeight;

    //A 3D array of game objects to be filled
    [SerializeField]
    GameObject[,,] goPrefabs;

    //Prefab of game object to put in 3D array
    public GameObject goPrefab; 

    public void fillArray()
    {
        iLength = (int)(transform.localScale.x);
        iWidth = (int)(transform.localScale.z);
        iHeight = (int)(transform.localScale.y);
        goPrefabs = new GameObject[iLength, iHeight, iWidth];

        //Fill the array with game objects
        for(int i = 0; i < iLength; i++)
        {
            for(int j = 0; j < iHeight; j++)
            {
                for(int k = 0; k < iWidth; k++)
                {
                    GameObject goCurrentObject = Instantiate(goPrefab) as GameObject;

                    goPrefabs[i, j, k] = goCurrentObject;
                }
            }
        }
    }

Make sure the array is serializable (either public, or marked with the SerializeField attribute). You might also need to mark the object as 'dirty' from the editor script, although I can never remember exactly how that's supposed to work.

If that doesn't help, maybe you could post the variable declaration for the array.
