The unity editor randomly generates objects. After changing the scene, the problem of object loss is solved

Preface ：

obj= (GameObject) PrefabUtility.InstantiatePrefab(configData.bigMainScene);

When I develop the editor, I instantiate the prefab into the scene , After jump scene , Then returning to the scene of the instantiated object will cause the object we created before to be lost , This situation ！ Very pit , Because there will be no prompt for unsaved scenes , Record the solution here

solve ：

I don't think this is a complete solution , But this method is the same as when we right-click to create an object , Give Way Unity Save it for us again , Record it in the cancellation data , That's it , The code is as follows , Mainly used PrefabUtility .UnpackPrefabInstance（） This method .

Details please see API

Unity - Scripting API: PrefabUtility.UnpackPrefabInstance

   obj = (GameObject) PrefabUtility.InstantiatePrefab(configData.smallMainScene);
        PrefabUtility.UnpackPrefabInstance(obj, PrefabUnpackMode.OutermostRoot, InteractionMode.UserAction);
