Making Retro Games with Python
 |
Description
Book Introduction
Deeper than YouTube, easier than development documentation!
The most user-friendly step-by-step guide to retro game development.
The games we'll be creating together in this book are simple, yet immersive retro games where you bounce balls to clear blocks or shoot bullets to eliminate enemies.
You'll experience the thrill of seeing your own code come to life with every bounce, bullet, and score.
And that experience tells us again:
“I think if we just try a little more, the real game will be complete.”
Of course, not everything goes smoothly from the start.
Every single thing can be a new challenge: bouncing the ball accurately, keeping the bullets from going off the screen, or coding the logic to increase your score.
But as you solve these small problems one by one, you will experience the game becoming more and more like a game.
That's when you'll go beyond simple learning and experience the joy of creating.
The important thing is not to do it perfectly, but to keep trying until the end.
Even the smallest successes add up to great accomplishments.
Simple functions are connected one by one, and eventually become a complete work.
This book will serve as a guide to help you complete just that first piece.
