Utility class for any prefab related operations.

//Create a folder (right click in the Assets directory, click Create>New Folder) and name it “Editor” if one doesn’t exist already.
//Place this script in that folder

//This script creates a new menu and a new menu item in the Editor window // Use the new menu item to create a prefab at the given path. If a prefab already exists it asks if you want to replace it //Click on a GameObject in your Hierarchy, then go to Examples>Create Prefab to see it in action.
