A scene diagram is useful when designing the skeleton of the application. For now, the scene is just a screen that is part of our game. We want to have a few different screens in our game, that is, different scenes. A typical game contains at least a splash scene, a menu scene, and a game scene. A splash scene is usually used to load resources in the background while showing a badge or logo of the game author.
We can add a loading scene between the menu and the game or between different levels or stages of the game. Some games will also have a special scene for game settings, final score, hall of fame, and so on.
We will keep our scenes to a minimum. The following is a simple diagram that shows transitions from one scene to another. Notice the Back label. That means the user taps the back button on the device.
