UIToolkit-based inspector for StateMachineBehaviour

Hi all, is it possible to create an inspector for a StateMachineBehaviour using UIElements/UIToolkit?
I'm trying to create one (in Unity 2019.3.7f1) and in my custom inspector the CreateInspectorGUI() is never invoked:

Code (CSharp):

1.  
2.     [CustomEditor(typeof(MyBehaviour), true)]
3.     public class MyBehaviourInspector : Editor
4.     {
5.         public override VisualElement CreateInspectorGUI()
6.         {
7.             Debug.Log("MyBehaviourInspector");
8.             var visualTree = Resources.Load<VisualTreeAsset>("EadonSpellAttackInspector");
9.             var uxmlVE = visualTree.CloneTree();
10.             uxmlVE.styleSheets.Add(Resources.Load<StyleSheet>("Eadon"));
11.             return uxmlVE;
12.         }
13.  
14. /*
15.         public override void OnInspectorGUI()
16.         {
17.             GUILayout.BeginVertical("Test", "window", GUILayout.ExpandWidth(true));
18.             GUILayout.BeginHorizontal();
19.             EditorGUILayout.LabelField("TEST", EditorStyles.boldLabel);
20.             GUILayout.EndHorizontal();
21.             GUILayout.EndVertical();
22.         }
23. */
24.     }
25.  

If I comment the method and uncomment the OnInspectorGUI() method, then I can see my custom inspector.
Anyone else facing the same problem?

 

Hi @antoine-unity thanks for the clarification. I’ll stick to IMGUI. At least I know I was not doing something wrong...

 

2 years later - is there any update on this? Just attempted (and failed) to make a custom inspector for a Statemachinebehaviour using UI Toolkit. Hopefully this is on the roadmap by now

 

Is this still an issue?

 

I would like to know if this in development, or if we can expect it soon.
If not, is there any workaround without recreating all my custom drawers in IMGUI.

 

I found one workaround for the issue

Code (CSharp):

1. using UnityEditor;
2.  
3. class InspectSMBInUIToolkit {
4.     [MenuItem("CONTEXT/StateMachineBehaviour/Inspect in UIToolkit", priority = 100)]
5.     internal static void WatchScriptableObject(MenuCommand command) {
6.         Selection.activeObject = command.context;
7.     }
8. }

This will allow you to right click a SMB header and choose 'Inspect in UIToolkit', which will allow UIToolkit based custom editors and property drawers

I still would prefer an official solution, as this requires an extra step for modifying each SMB, but it's better than nothing
