Question Custom Inspector doesn't save Scriptable Object data when restarting Unity Project

Hi. I have a custom editor to Add or Remove FeedbackData in FeedbackDataList.
The functions works well in Editor but when I restart the project the scriptable object data is empty.
But when I tweak the value directly inside the scriptable object the data persist.





These are my scripts.

Code (CSharp):

1. [CreateAssetMenu(fileName = "Feedback Data", menuName = "ETAS/Feedback")]
2.     public class FeedbackDataSO : ScriptableObject
3.     {
4.         public Pose CollapsePose;
5.         public Pose ExpandPose;
6.         public List<FeedbackData> FeedbackDataList = new();
7. }
8.  
9.     [System.Serializable]
10.     public struct FeedbackData
11.     {
12.         public Pose Pose;
13.         public float Duration;
14.  
15.         public FeedbackData(Vector3 pos, Quaternion rot, float duration)
16.         {
17.             Pose.position = pos;
18.             Pose.rotation = rot;
19.             Duration = duration;
20.         }
21.     }
22.  
23. [CustomEditor(typeof(StepControllerV2))]
24.     public class StepControllerV2Editor : Editor
25.     {
26.         StepControllerV2 step = null;
27.  
28.         void OnEnable()
29.         {
30.             step = target as StepControllerV2;
31.         }
32.  
33.         public override void OnInspectorGUI()
34.         {
35.             base.OnInspectorGUI();
36.  
37.             serializedObject.Update();
38.  
39.             DisplayGenerateStepAndFeedbackButton();
40.  
41.             EditorGUILayout.PropertyField(serializedObject.FindProperty("FeedbackData"), true);
42.  
43.             DisplayAddAndRemoveFeedbackButton();
44.  
45.             serializedObject.ApplyModifiedProperties();
46. }
47.  
48. void AddFeedback ()
49.         {
50.             FeedbackData data = new FeedbackData(step.Position, step.Rotation, 1f);
51.             step.FeedbackData.FeedbackDataList.Add(data);
52.  
53.             step.FeedbackData.SetExpandPose(step.Position, step.Rotation);
54.  
55.             AssetDatabase.SaveAssets();
56.             AssetDatabase.Refresh();
57.         }
58.  
59.         void RemoveFeedback()
60.         {
61.             if (step.FeedbackDataFeedbackDataList.Count > 0)
62.             {
63.                 int lastIndex = step.FeedbackData.FeedbackDataList.Count - 1;
64.  
65.                 FeedbackData data = step.FeedbackData.FeedbackDataList[lastIndex];
66.  
67.                 step.transform.SetPositionAndRotation(data.Pose.position, data.Pose.rotation);
68.             }
69.             else
70.             {
71.                 step.transform.SetPositionAndRotation(step.FeedbackData.CollapsePose.position, step.FeedbackData.CollapsePose.rotation);
72.             }
73.  
74.             AssetDatabase.SaveAssets();
75.             AssetDatabase.Refresh();
76.         }

 

Whenever you modify an asset via code, you must inform Unity you have altered it. This is generally done via

EditorUtility.SetDirty

, but can also be done via recording the object via the

Undo

class.

In your case you need to dirty the scriptable objects.

 

Thank you. It works now
