Preface

The Rust programming language has held the "most-loved" technology ranking on Stack Overflow for 6 years running, while JavaScript has been the most-used programming language for 9 years straight, as it runs on every web browser (https://bit.ly/3JBg4ms). Now, thanks to WebAssembly (or Wasm), you can use the language you love on a platform that's everywhere. This book is an easy-to-follow reference to help you develop your own games, teaching you all about game development and how to create an endless runner from scratch. You'll begin by drawing simple graphics in the browser window, and then learn how to move the main character across the screen. You'll also create a game loop, a renderer, and more, all written entirely in Rust. After getting simple shapes onto the screen, you'll scale the challenge by adding sprites, sounds, and user input. As you advance, you'll discover how to implement a procedurally generated world and add sound effects and music. Finally, you'll learn how to keep your Rust code clean and organized so that you can continue to implement new features and deploy your app on the web. By the end of this Rust programming book, you'll have built a 2D game in Rust, deployed it to the web, and be confident enough to start building your own games.
