Custom Editor problem in Unity 5.3

Dear Unity developers,

I found a change of Custom Editor's behaviour in Unity 5.3.0.
Please check the attached sample project.

In my custom editor script(SantaEditor.cs), I call EditorUtility.SetDirty to save changes on Inspector.

Code (CSharp):

1. public override void OnInspectorGUI()
2. {
3.         Santa test = target as Santa;
4.  
5.     GUI.changed = false;
6.     {
7.         // some gui layout codes
8.     }
9.  
10.     if (GUI.changed) {
11.         EditorUtility.SetDirty(test);
12.     }
13. }

In 5.2.3 and before, this script works as intended.
However, it doesn't in 5.3.0.
It seems SetDirty work nothing and Editor can't notice changes in Custom Editor.

To reproduce:
1. Open TestScene01 in the attached project.
2. Select GameObject in Hierarchy, and make some changes on Santa(Script) in Inspector.
3. Save and re-open the TestScene01 scene.
4. You will find
-> Santa has modified values in 5.2.3 and before.
-> Santa has default values in 5.3.0.

To workaround, we have to make additional changes and save the scene.
In the attached project, for example, changes of Transform values or GameObject(1)'s Reindeer-"Is Nose Red" flag will make sense.
(Reindeer has no Custom Editor.)

I'm not sure this behaviour is intentional or not.
Welcome any comments or suggestions.

Thank you

 

Same problem.

 

Maybe you can delete 'Library' and 'Temp' folders first. I don't know if it works because I reinstalled 5.2.3.

 

This fix finely works.
Since 5.3.0, calling Undo.RecordObject seems definitely required for Custom Editor.

Thank you for your answer!

 

Good.

 

It works well, thanks guy~

 

Just saved me! Thank you!

 

I spent about an hour researching this after having issues with setDirty. This is what I've come up with so far, seems to be working great. Also, I'm loving how it automatically pulls the datatype of the SerializedProperty. Hopefully this helps someone.

Code (CSharp):

1.  
2. using UnityEngine;
3. using UnityEditor;
4. using System.Collections;
5.  
6. [CustomEditor(typeof(SpriteSheetAnimator))] //custom editor targeting my type SpriteSheetAnimator class
7. public class SpriteSheetAnimatorEditor : Editor //inheriting from Editor
8. {
9.     SerializedObject spriteScript;
10.  
11.     SerializedProperty columnProperty; //a field contained in my SpriteSheetAnimator class which will be of type          SerializedProperty
12.     SerializedProperty rowsProperty; //a field contained in my SpriteSheetAnimator class which will be of type SerializedProperty
13.     SerializedProperty spriteSheetProperty; //a field contained in my SpriteSheetAnimator class which will be of type SerializedProperty
14.  
15.     void OnEnable()
16.     {
17.         spriteScript = new SerializedObject(target);
18.  
19.         columnProperty = spriteScript.FindProperty("columns"); /*finding that field in the SpriteSheetAnimator class and assigning it to a SerializedProperty.
20.                                                                  columns is the name of that field*/
21.  
22.         rowsProperty = spriteScript.FindProperty("rows");
23.  
24.         spriteSheetProperty = spriteScript.FindProperty("spriteSheet");
25.     }
26.  
27.     public override void OnInspectorGUI()
28.     {
29.         spriteScript.Update(); //update serialized objects representation
30.  
31.  
32.         EditorGUILayout.PropertyField(columnProperty); /*for the next 3 lines
33.                                                          this automatically pulls the serialized field type and creates in in the inspector window
34.                                                           so if columnProperty was an int it would be created in the inspector as type int*/
35.  
36.         EditorGUILayout.PropertyField(rowsProperty);
37.  
38.         EditorGUILayout.PropertyField(spriteSheetProperty);
39.  
40.  
41.         spriteScript.ApplyModifiedProperties(); /*applies the modified properties for the Serialized Object - IE: I type 1 into the columns field which was created earlier
42.                                                   in the inspector, this saves that into the columns variable*/
43.  
44.  
45.         if(GUILayout.Button("Process"))
46.         {
47.             //call some method
48.         }
49.     }
50. }
