Exposed blackboard AnimationCurve changes aren't registered

[kiamvdd]

Exposed AnimationCurve blackboard variables do not register any changes made in the graph owner inspector.

How to reproduce:
1. Create a behavior tree owner in an empty scene
2. Create a bound graph on the owner
3. Create an AnimationCurve graph variable
4. Expose the variable and override it
5. Save the scene
6. Modify the exposed variable in the inspector
7. Note that the scene is not marked as dirty, despite having made a change

We have temporarily been able to fix this by adding a EditorGUI.BeginChangeCheck() in EditorUtils.ReflectedInspector.DrawEditorFieldDirect(), right before the call to DirectFieldControl(), and then taking EditorGUI.EndChangeCheck() into account in the “changed” check. The code then looks like this:

1 2 3 4 5 6 7

EditorGUI.BeginChangeCheck(); var newValue = DirectFieldControl(content, value, t, info.unityObjectContext, info.attributes, out handled); var changed = !object.Equals(newValue, value) || EditorGUI.EndChangeCheck();   if (changed) UndoUtility.RecordObjectComplete(info.unityObjectContext, content.text + "Field Change"); value = newValue; if ( changed ) { UndoUtility.SetDirty(info.unityObjectContext); }

Don’t know if this is the best solution, but it seems to work for us.

Hi. Thanks and good call.
I will look into it, but your fix seems good and in the correct spot 🙂
