I am trying to make an EditorWindow that will store global data about my application, data which I want every level to be able to access. So my first route of going about this was to just make a static public class GlobalData. In it is all the data I want to store. Then in my EditorWindow I do a simple GlobalData.whatever this works in between opening and closing the EditorWindow. But not inbetween opening and closing Unity. It seems to not save changes to the variables in my static class. I do have [System.Serializable] put about my static class, and I have even tried calling SetDirty on my GlobalData data, but that doesn't work.

From the advices of someone else I tried to create GlobalData NOT as a static, but rather just public. Then I create an Instance of GlobalData in my EditorWindow Class. But this does not save the data between opens and closes of even just the EditorWindow! I assume of course because the instance of GlobalData is being made in the EditorWindow so it loses that instance when it is closed.

I've tried messing around with making my GlobalData class a ScriptableObject, but that doesn't work.

I've seriously spent like the past 18 hours sitting here trying any and everything I can think of and am running out of ideas :( Please Help. If anyone could just give me the most base simple example code for an EditorWindow that somehow saves it's data between open and closes of Unity, I would be so grateful. I cannot find any example projects anywhere that show how to do this.

And here is the code I've made thus far:

using UnityEngine;
using UnityEditor;

public class PanoSetup : EditorWindow
{
    [MenuItem ("Window/PanoSetup")]
    static void Init () {
        //PanoSetup window = 
       EditorWindow.GetWindow (typeof (PanoSetup));
    }

    void OnGUI () {
       GlobalData.texture = (Texture2D) EditorGUILayout.ObjectField(
            "Find Dependency",
            GlobalData.texture,
            typeof(Texture2D)); 
    }
}

using System.Collections;
using UnityEngine;

[System.Serializable]
static public class GlobalData {

    static public string texturePath = "temp";
    static public int what = 1;
    static public Texture2D texture = null;

}
