Game Development with Rust and WebAssembly
Write an endless runner game for the web in Rust and test, deploy, and debug your 2D game using the WebAssembly toolchain Key Features Build and deploy an endless runner game for the web from scratch through this helpful guide with key images printed in color Learn how to use Rust for web development with WebAssembly Explore modern game development and programming techniques to build 2D games using Rust Book DescriptionThe 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.What you will learn Build and deploy a Rust application to the web using WebAssembly Use wasm-bindgen and the Canvas API to draw real-time graphics Write a game loop and take keyboard input for dynamic action Explore collision detection and create a dynamic character that can jump on and off platforms and fall down holes Manage animations using state machines Generate levels procedurally for an endless runner Load and display sprites and sprite sheets for animations Test, refactor, and keep your code clean and maintainable Who this book is for This game development book is for developers interested in Rust who want to create and deploy 2D games to the web. Game developers looking to build a game on the web platform using WebAssembly without C++ programming or web developers who want to explore WebAssembly along with JavaScript web will also find this book useful. The book will also help Rust developers who want to move from the server side to the client side by familiarizing them with the WebAssembly toolchain. Basic knowledge of Rust programming is assumed.
Programming WebAssembly with Rust

WebAssembly fulfills the long-awaited promise of web technologies: fast code, type-safe at compile time, execution in the browser, on embedded devices, or anywhere else. Rust delivers the power of C in a language that strictly enforces type safety. Combine both languages and you can write for the web like never before! Learn how to integrate with JavaScript, run code on platforms other than the browser, and take a step into IoT. Discover the easy way to build cross-platform applications without sacrificing power, and change the way you write code for the web. WebAssembly is more than just a revolutionary new technology. It's reshaping how we build applications for the web and beyond. Where technologies like ActiveX and Flash have failed, you can now write code in whatever language you prefer and compile to WebAssembly for fast, type-safe code that runs in the browser, on mobile devices, embedded devices, and more. Combining WebAssembly's portable, high-performance modules with Rust's safety and power is a perfect development combination. Learn how WebAssembly's stack machine architecture works, install low-level wasm tools, and discover the dark art of writing raw wast code. Build on that foundation and learn how to compile WebAssembly modules from Rust by implementing the logic for a checkers game. Create wasm modules in Rust to interoperate with JavaScript in many compelling ways. Apply your new skills to the world of non-web hosts, and create everything from an app running on a Raspberry Pi that controls a lighting system, to a fully-functioning online multiplayer game engine where developers upload their own arena-bound WebAssembly combat modules. Get started with WebAssembly today, and change the way you think about the web. What You Need: You'll need a Linux, Mac, or Windows workstation with an Internet connection. You'll need an up-to-date web browser that supports WebAssembly. To work with the sample code, you can use your favorite text editor or IDE. The book will guide you through installing the Rust and WebAssembly tools needed for each chapter.
\0asm 01 - Rust and WebAssembly
The book is written in a cookbook style. Each recipe focuses on a concept in the WebAssembly world. Part 1 focuses on the basics of WebAssembly, WebAssembly Text Format, onboarding and using various tools like WABT, Binaryen. Chapter 1 gives a brief introduction to LLVM. What it is and how to use it. Chapter 2 introduces you into the emscripten world. Emscripten is a toolchain that helps to convert C/C++ into WebAssembly module. We will see how to install and manage the emscripten toolchain. Create our first WebAssembly module and run it on the browser and Node environment. Chapter 3 explores the WebAssembly module, how the module is made and what are the different sections. We will also explore the WebAssembly Text Format and how to write WebAssembly Text Format and convert it to WebAssembly binary. Chapter 4 explores how to install and use WebAssembly Binary Toolkit (WABT). Chapter 5 explores various section inside the WebAssembly binary and what are its purpose. Chapter 6 explores how to install and use Binaryen. Part 2 focuses on converting Rust to WebAssembly for fast, reliable code to run on the JavaScript Engine. Find out various ways of sharing data between Rust and WebAssembly. Explore how to use various tools that Rust and WebAssembly ecosystem provides. Chapter 7 starts with Rust and various ways to convert Rust into WebAssembly module and ends with wasm_bindgen. Chapter 8 focuses on how wasm bindgen along with crates like js-sys, web-sys helps to share entities from the WebAssembly world to JavaScript world. Chapter 9 explores wasm-pack and how it makes it easy to build Rust and WebAssembly application. Chapter 10 explores some Rust and WebAssembly examples. Chapter 11 briefly introduces WebAssembly System Interface (WASI) and various ways to run WASI.
