Learn to build a fully-functional 2D game inspired by the 1979 Atari classic, Asteroids, using just HTML5, CSS and JavaScript. Developing games has never been easier than it is now. New web technology allows even beginner developers to turn their hand to game development. Developed from an undergraduate course module, Introducing JavaScript Game Development teaches each new technology as it is introduced so can be followed by enthusiastic beginners as well as intermediate coders.

You will learn how to work with HTML5 and the canvas element, how to understand paths, how to draw to a design and create your spaceship and asteroids. You’ll then move on to animating your game, and finally building. You will work step-by-step through the game design process, starting with only what is necessary to complete each step, and refactoring the code as necessary along the way, reflecting the natural progression that code follows in the real world. Each chapter is designed to take your code base to the next level and to add to your skills. After completing the examples in this book you will have the tools necessary to build your own, high-quality games.

Make the process of creating object-oriented 2D games more fun and more productive and get started on your game development journey.

学习建立一个功能齐全的2D游戏，其灵感来自1979年雅达利的经典游戏《小行星》，只需使用HTML5、CSS和JavaScript。开发游戏从未像现在这样简单。新的网络技术使初学者也能转而从事游戏开发。JavaScript游戏开发介绍》从一个本科课程模块发展而来，在介绍每项新技术时都进行了讲授，因此，热情的初学者和中级编码员都可以学习。

你将学习如何使用HTML5和画布元素，如何理解路径，如何绘制设计图并创建你的飞船和小行星。然后，你将继续为你的游戏制作动画，最后是建造。你将在游戏设计过程中一步一步地工作，只从完成每一步所需的内容开始，并在途中根据需要重构代码，反映出代码在现实世界中的自然进展。每一章都是为了将你的代码库提升到新的水平，并增加你的技能。在完成本书的例子后，你将拥有建立自己的高质量游戏的必要工具。

让创建面向对象的2D游戏的过程更有趣、更有成效，开始你的游戏开发之旅吧。
