Congratulations, you just wrote your first game using Rust. All of the basic elements of the original Flappy Bird are present, and you can even compete for high scores.
You have plenty of ways to improve Flappy Dragon. Here are some exercises to try:
- Play with the gravity level, velocity changes, and game speed. Notice how different values can radically change the feel of the game.
- See if you can add graphics for the walls and dragon.
- Consider making the graphics bigger and the overall play area smaller to better match Flappy Bird.
- Investigate bracket-lib’s “flexible console” and change the player coordinates to floating-point numbers for smoother movement.
- Add color and visual flair to the menus.
- Try animating the dragon.
A version of Flappy Dragon, including most of these enhancements, is included with the book’s source code. You can find it in the flappy_bonus directory. Thanks to Bevouliin for the dragon artwork.[39] Flappy Dragon Enhanced looks like this:
In the next chapter, you’ll begin designing a more ambitious game: a roguelike dungeon crawler.
