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.

Technical requirements

To follow along with the project skeleton, you'll need to install rustup to install the Rust toolchains. This can be found at https://rustup.rs/. While you can install Rust and its various toolchains without using the rustup tool, it's not trivial, and I won't be documenting it here. You'll also need an editor for writing Rust code, and while you can use virtually any editor with rust-analyzer, if you're new to writing Rust, I'd recommend Visual Studio Code and the Rust extension found at https://bit.ly/3tAUyH2. It's easy to set up and works right out of the box.

Finally, you'll need a web browser, and in this chapter, you'll need some familiarity with the terminal and Node.js. If you get stumped, the code for this chapter is available at https://github.com/PacktPublishing/Game-Development-with-Rust-and-WebAssembly/tree/chapter_1. The final code for the entire book is in the main branch at https://github.com/PacktPublishing/Game-Development-with-Rust-and-WebAssembly.
