Question by BrkTbn · Jul 26, 2016 at 11:05 AM · editoranimationcurveserializedpropertyundoserializedobject

Undo Problem With Curve Fields In Custom Editor Window

Hi,

In my editor window there are curve fields and I hold the AnimationCurve values in an array inside the editor class, and a copy inside a ScriptableObject. I tried using Undo.RecordObject on the ScriptableObject but no luck. Currently I am trying SerializedObject and SerializedProperty method, but it is not working. This code adds changes to undo stack but wrong changes, or they become corrupt or something. When I undo more then two moves in curve editor, or try Redo, it looks like it has been done but the result is wrong, Is it an issue with curve fields or am I doing it wrong?

I set the mySerializedObject in the Initialization, with "new SerializedObject( myScriptableObject )". My code is basicly this:

 void OnGUI
 {
 
 //........
 
     if(GUI.changed)
     {                    
     
                mySerializedObj.Update();
     
                SerializedProperty p = mySerializedObj.FindProperty(string.Format("animationCurves.Array.data[{0}]", i));
     
                 AnimationCurve a = p.animationCurveValue;
     
                  a.keys = new Keyframe[animationCurves[i].keys.Length];
     
                  animationCurves[i].keys.CopyTo(a.keys, 0);
     
                  p.animationCurveValue = a;
     
                  obj.ApplyModifiedProperties();
     }
 
 //........
 
 }


Thanks in advance.

Solved my own problem by using PropertyFields and modifying the SerializedProperty directly, rather than using CurveFields and copying the data to ScriptableObject.
