About this book

The Rust programming language has held the 'most loved' technology ranking on Stack Overflow for 5 years running, while JavaScript has been the most used programming language for 8 years straight as it runs on every web browser. Now, thanks to WebAssembly (or Wasm), you can use the language you love, on the platform that's everywhere.

In fact, you can use Rust to build games! This book is an easy-to-follow reference to help you make your own games, teaching you all about game development by creating 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 become proficient in background processing in Rust. Finally, you'll learn how to keep your Rust code clean and organized so you can continue to implement new features and deploy your app on the web.

By the end of this Rust programming book, you'll build a 2D game in Rust, deploy it to the web, and be confident enough to then start building your own games.
