How to get prefab path from prefab game object?

Code (CSharp):

1. [InitializeOnLoad]
2. public static class SavePrefabFile
3. {
4.     static SavePrefabFile()
5.     {
6.         PrefabStage.prefabSaved += OnPrefabSaved;
7.     }
8.  
9.     static void OnPrefabSaved(GameObject prefab)
10.     {
11.         // path is empty? how can I get the right path from prefab?
12.         var path = AssetDatabase.GetAssetPath(prefab);
13.     }
14. }
15.  

 

it must be something wrong with `PrefabStage.prefabSaved` callback, since `PrefabUtility.prefabInstanceUpdated` works well.

Code (CSharp):

1.         static SavePrefabFile()
2.         {
3.             // PrefabStage.prefabSaved -= OnPrefabSaved;
4.             // PrefabStage.prefabSaved += OnPrefabSaved;
5.             PrefabUtility.prefabInstanceUpdated += OnPrefabSaved;
6.         }
7.  
8.         static void OnPrefabSaved(GameObject prefab)
9.         {
10.             // all those value were null if use callback of `PrefabState.prefabSaved`
11.             var PrefabInstanceHandle = PrefabUtility.GetPrefabInstanceHandle(prefab);
12.             var CorrespondingObjectFromSource = PrefabUtility.GetCorrespondingObjectFromSource(prefab);
13.             var OutermostPrefabInstanceRoot = PrefabUtility.GetOutermostPrefabInstanceRoot(prefab);
14.             var NearestPrefabInstanceRoot = PrefabUtility.GetNearestPrefabInstanceRoot(prefab);
15.             var CorrespondingObjectFromOriginalSource = PrefabUtility.GetCorrespondingObjectFromOriginalSource(prefab);
16.             var path = PrefabUtility.GetPrefabAssetPathOfNearestInstanceRoot(prefab);
17.         }
18.  

 

Code (CSharp):

1.     void Start()
2.     {
3. #if UNITY_EDITOR
4.         // Assuming you have a reference to the prefab game object
5.         GameObject prefabGameObject = gameObject;
6.  
7.         // Get the prefab path
8.         string prefabPath = PrefabUtility.GetPrefabAssetPathOfNearestInstanceRoot(prefabGameObject);
9.  
10.         Debug.Log("Prefab Path: " + prefabPath);
11. #endif
12.     }
