HTML5 Canvas Cookbook

By: Eric Rowell

Overview of this book

The HTML5 canvas is revolutionizing graphics and visualizations on the Web. Powered by JavaScript, the HTML5 Canvas API enables web developers to create visualizations and animations right in the browser without Flash. Although the HTML5 Canvas is quickly becoming the standard for online graphics and interactivity, many developers fail to exercise all of the features that this powerful technology has to offer.The HTML5 Canvas Cookbook begins by covering the basics of the HTML5 Canvas API and then progresses by providing advanced techniques for handling features not directly supported by the API such as animation and canvas interactivity. It winds up by providing detailed templates for a few of the most common HTML5 canvas applications—data visualization, game development, and 3D modeling. It will acquaint you with interesting topics such as fractals, animation, physics, color models, and matrix mathematics. By the end of this book, you will have a solid understanding of the HTML5 Canvas API and a toolbox of techniques for creating any type of HTML5 Canvas application, limited only by the extent of your imagination.

Of all the chapters in this book, this chapter was by far my favorite (with the next chapter being a close second). We might not actually be able to save the world with game development, but it sure is fun to create our own virtual worlds and save those instead. In this chapter, we're going to pull all of our new found knowledge together to create Canvas Hero, a side-scroller action game starring the Canvas Hero, who can run, jump, levitate, and punch through a futuristic world full of menacing bad guys. Here are some of the features of the game:

  • The hero can run left, run right, jump, and punch to attack

  • The level will look futuristic

  • The level will be full of enemies running around looking for trouble

  • The level will have a foreground image that moves to the left and to the right as the player moves...
