Game Development with Rust and WebAssembly

By: Eric Smith

Overview of this book

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. Now, thanks to WebAssembly (or Wasm), you can use the language you love on the 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. 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 start building your own games.

A challenging review

Reviewing code in a book is a strange concept; after all, you can just flip back to the earlier chapters to review what you've learned, so why bother to reiterate that now? At the same time, I've taught a lot of classes, and if there's one thing that's consistent, it's that sometimes smart students sit quietly, listen, nod, and then leave the classroom without understanding anything that you've just said. The only way to get an understanding is to take the knowledge we've practiced so far and build something upon it. Fortunately, we have just the thing.

What happened to the dog?

In Chapter 2, Drawing Sprites, we did a quick game design session where we described how our little Red Hat Boy (RHB) would be chasing his dog, who was startled by a cat. Yet, in the proceeding nine chapters, there has been no sign of the dog. Simply put, adding the dog, and a cat, requires very little that you don't already know how to do and...
