Let's define the app states now, as described in the beginning of this section.

Create a new C# script in your Scripts folder named AppStates and edit it as follows to define an enum of the states:

File: AppStates.cs
public enum AppStates { 
    OVERLAY_OUTLINE, INIT_ANIMATION, SCANNING, GAME_RENDERING, GAME_PLAY, RESET_ALL, NONE 
}
