GameObject The root GameObject of the saved Prefab Asset, if available.
Use this function to create a Prefab Asset at the given path from the given GameObject including any children in the Scene and at the same time make the given GameObject into an instance of the new Prefab.
In case some of the children are Prefab instances they will automatically become nested inside the new Prefab.
The input object has to be a plain GameObject or the outermost root of a Prefab Instance. It cannot be a child inside a Prefab instance.
If the input object is a Prefab instance root the resulting Prefab will be a Variant Prefab. Should you in this case actually want to create a new uniqueue Prefab you need to unpack the instance first.
The returned object is the root GameObject of the saved Prefab Asset, if available. If the editor in currently in the middle of an asset editing batch operation, as controlled with AssetDatabase.StartAssetEditing and AssetDatabase.StopAssetEditing, assets are not immediately imported upon being saved. In this case, SaveAsPrefabAsset will return null even if the save was successful because the saved Prefab Asset was not yet reimported and thus not yet available.
