Question A way or a tool to check if and where a gameobject is being called in timelines / animations.

Hello, I was wondering if someone knows a way to check in the hierarchy of a scene if a specific gameobject is being controlled/assigned in any timelines or animators in the project.

 

Hello,
Timeline has two type of bindings: generic binding and reference bindings, and they are all saved in scene.
So if you check all timeline's binding table, you can get the objects they attached.

Code (CSharp):

1.     public static void SearchAllBindings()
2.     {
3.         foreach (var scenePath in AssetDatabase.FindAssets("t:scene").Select(AssetDatabase.GUIDToAssetPath))
4.         {
5.             var scene = EditorSceneManager.OpenScene(scenePath);
6.             Debug.Log($"Processing scene:{scenePath}");
7.             foreach (var director in scene.GetRootGameObjects().SelectMany(x => x.GetComponentsInChildren<PlayableDirector>()))
8.             {
9.                 var so = new SerializedObject(director);
10.                 so.forceChildVisibility = true;
11.                 var sceneBinding = so.FindProperty("m_SceneBindings");
12.                 for (int i = 0; i < sceneBinding.arraySize; i++)
13.                 {
14.                     var property = sceneBinding.GetArrayElementAtIndex(i);
15.                     var keyProp = property.FindPropertyRelative("key");
16.                     var valueProp = property.FindPropertyRelative("value");
17.                     var resolvedValue = director.GetGenericBinding(keyProp.objectReferenceValue);
18.                     if (resolvedValue != null)
19.                     {
20.                         Debug.Log($"  object:{resolvedValue} is binding to:{director}", resolvedValue);
21.                     }
22.                 }
23.                 var refBinding = so.FindProperty("m_ExposedReferences").FindPropertyRelative("m_References");
24.                 for (int i = 0; i < refBinding.arraySize; i++)
25.                 {
26.                     var property = refBinding.GetArrayElementAtIndex(i);
27.                     var firstProp = property.FindPropertyRelative("first");
28.                     var valueProp = property.FindPropertyRelative("second");
29.                     var value = (director as IExposedPropertyTable).GetReferenceValue(new PropertyName(firstProp.stringValue), out var isValid);
30.                     Debug.Log($"  object:{valueProp.objectReferenceValue},{value} is binding to:{director}", valueProp.objectReferenceValue);
31.                 }
32.             }
33.         }
34.     }

Good luck.
