Professional HTML5 Mobile Game Development

Introduction

The spritesheet support from Chapter 11, “Bootstrapping the Quintus Engine: Part III,” allowed Sprites with spritesheets to play back animations by modifying the frame property of a sprite. Although this approach works for simple games with single animations, more complicated games such as the platformer built in Chapter 18, “Creating a 2-D Platformer,” require a more robust system to handle animation. This chapter builds an animation system that enables more complex behaviors. This chapter also examines what you need to build and animate Canvas-based parallax scrolling backgrounds.
