Scene not set dirty when using Serializables in Custom Editor

Hi,

i'm using a Serializable class to edit it's values in the inspector. This works fine when i use it directly in a MonoBehavior, but when i use a custom editor script to manipulate the data the scene is not set dirty. It's really annoying that i can't save a scene after i edited the values in the inspector.

Here is a small example for demonsration:

Code (CSharp):

1. using UnityEngine;
2. public class DataManager : MonoBehaviour
3. {
4.     public Data data;
5. }
6.  
7. using System;
8. [Serializable]
9. public class Data
10. {
11.     public int num;
12. }
13.  
14. using UnityEditor;
15. [CustomEditor(typeof(DataManager))]
16. public class DataEditor : Editor
17. {
18.     private DataManager dataManager;
19.  
20.     public override void OnInspectorGUI()
21.     {
22.         dataManager = target as DataManager;
23.         dataManager.data.num = EditorGUILayout.IntField(dataManager.data.num);
24.     }
25. }

The only solution i found is to manually check for changes in OnInspectorGUI and then set the scene dirty or use EditorGUI.BeginChangeCheck(); and Undo.RecordObject, but that means i need to write additional code for every single variable.

Is there no better solution for this?

 

Thanks. That works. The problem is that refactoring becomes a nightmare when using strings. The code would be a lot nicer with the nameof operator in C# 6.0
