Resolved How to modify an animating property value with manipulator in timeline?

Hi,
I Create a custom timeline track with recording system. When I started to recorded it ,and modified the properties on the inspector, It worked perfectly.



Then I created a manipulator on the scene view via script, and try to use it to modified properties, but it seems didn't work.




Here is my code.

Code (CSharp):

1.  
2.  
3.     [CustomEditor(typeof(CameraClip))]
4.     public class CameraClipInspector : Editor
5.     {
6.         .....other code.....
7.  
8.         private void OnSceneGUI(SceneView sceneView)
9.         {
10.             DoManipulators();
11.         }
12.  
13.         private void DoManipulators()
14.         {
15.             var clip = target as CameraClip;
16.  
17.             if (null == clip || null == clip.BindingCamera)
18.                 return;
19.  
20.             var camTrans = clip.BindingCamera.transform;
21.             if (camTrans == null || _mode == OffsetEditMode.None)
22.                 return;
23.  
24.             Vector3 position = camTrans.position;
25.             Quaternion rotation = camTrans.rotation;
26.  
27.             EditorGUI.BeginChangeCheck();
28.             if (_mode == OffsetEditMode.Position)
29.             {
30.                 position = Handles.PositionHandle(position, Tools.pivotRotation == PivotRotation.Global ? Quaternion.identity : rotation);
31.             }
32.             else if (_mode == OffsetEditMode.Rotation)
33.             {
34.                 rotation = Handles.RotationHandle(rotation, position);
35.             }
36.  
37.             if (EditorGUI.EndChangeCheck())
38.             {
39.                 var window = TimelineWindow.instance;
40.                 if (null != window && null != window.state && window.state.recording)
41.                 {
42.                     clip.template.position = position;
43.                     clip.template.eulerAngles = rotation.eulerAngles;
44.  
45.                     window.state.rebuildGraph = true;
46.                     window.RebuildGraphIfNecessary(true);
47.                 }
48.             }
49.         }
50.  
51.         .......other code......
52.     }
53.  
54.  

Code (CSharp):

1.  
2.     [Serializable]
3.     public class CameraClip : PlayableAsset
4.     {
5.         public CameraBehaviour template = new CameraBehaviour();
6.  
7.         public override Playable CreatePlayable(PlayableGraph graph, GameObject owner)
8.         {
9.             var playable = ScriptPlayable<CameraBehaviour>.Create(graph, template);
10.             return playable;
11.         }
12.  
13.     }
14.  

Code (CSharp):

1.  
2.     [Serializable]
3.     public class CameraBehaviour : PlayableBehaviour
4.     {
5.         public Vector3 position = Vector3.zero;
6.         public Vector3 eulerAngles = Vector3.zero;
7.         public float fov = 20f;
8.     }
9.  

I hope I was clearly explained the issue, If someone know the answer, please help me.

 

@DavidGeoffroy I tried to modify SerializedProperty and it worked! Thank you so much!
