At this point, I have assumed that you have a fresh installation of Unity, and have started it up. You need to perform the following steps:
Open the previous project. Now, let's first create a new scene by navigating to File | New Scene. With the new scene created, save it by navigating to File | Save Scene. Name it
Main_Menu.unity
and save it inside yourScenes
folder.Let's first grab the background from our previous level so that we do not need to create it once again. To do that, double-click on the scene you created in the first chapter. Left-click on the Background object in the Hierarchy view and navigate to Edit | Copy. Go back to your
Main_Menu
scene and paste it into the world by navigating to Edit | Paste:Unity has an inbuilt GUI functionality through the UnityGUI system that allows us to create interfaces through scripts.
