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.

Chapter 7: Sound Effects and Music

Take a moment and think of the game Tetris. If you're like me, you're probably already humming its theme song, Korobeiniki, because that song is so synonymous with the game itself. Beyond the appeal of music, sound effects are crucial for creating an immersive experience. We play games with more than just the touch of a keyboard or joystick and the use of our eyes; we hear Mario jump or Sonic catch a ring. While our game may be playable, it's just not a game without some sound. To play sound in our game, we'll need to learn how to use the browser's Web Audio API for both short and long sounds.

In this chapter, we will cover the following topics:

  • Adding the Web Audio API to the engine
  • Playing sound effects
  • Playing long music

By the end of this chapter, you won't just see RHB run, jump, and dodge obstacles, but you'll be able to hear him too after we add sound effects and music to our game...
