Game State

So a game state is something like the start menu vs the play state of a game. I’m used to seeing it as it’s own class, but I guess that can be baked down simpler like below.

I’m thinking in C I’ll just implement a game-state like this

enum GameState {
    START_MENU,
    PLAY_STATE,
    END_SCREEN
}

GameState gameState = START_MENU;

void update(void) {
    switch (gameState) {
        case START_MENU:
            startMenu();
            break;
        case PLAY_STATE:
            playState();
            break;
        case END_SCREEN:
            endScreen();
            break;
        default:
            break;
    }
}
