Saving its values through custom Editor

[gregmax17]

This is my first time trying to create an Editor script to edit an prefab properties and values through the Editor. I am having issues saving the prefabs array. I am able to add/remove objects to the array, but once I click on the PLAY button, the array is destroyed.

This is my Editor script:

`
#pragma strict

@CustomEditor(MyController)

class MyControllerEditor extends Editor
{
function OnInspectorGUI()
{
var my : MyController = target as MyController;

	GUILayout.BeginHorizontal("Button");
		if ( GUILayout.Button("Add Object to Array") )
		{
			my.someArray.Push(new Object());
		}
		if ( GUILayout.Button("Remove Object from Array") )
		{
			my.someArray.RemoveAt(0);
		}
		if ( GUILayout.Button("Remove All from Array") )
		{
			my.someArray = new Array();
		}
	GUILayout.EndHorizontal();

	my.randomVariable = EditorGUILayout.IntField("Hello", my.randomVariable);
}

}
`

This script is attached to the prefab:

`
#pragma strict

var someArray : Array = new Array();
var randomVariable : Int = 0;

class someObject()
{
var prop1 : String = “a value”;
var prop10 : String = “a longer value”;
}
`

Am I doing this the proper way? How come the array is being destroyed when I PLAY and STOP the game in the Preview? Side note: setting the ‘randomVariable’ in the Editor works fine.

I think you’re looking for EditorUtility.SetDirty()

I’m not certain, but I suspect the problem is Unity not serializing an Array, since that won’t work in the default
inspector either. If you use a normal built-in array, it should work:

my.someArray += [new Object()];

etc.

var someArray = new Object[0];
