About the Authors

Steffen Itterheim has been a game development enthusiast since the early 1990s. His work in the Doom and Duke Nukem 3D communities landed him his first freelance job as a beta tester for 3D Realms. He has been a professional game developer for more than a decade, having worked most of his career as a gameplay and tools programmer for Electronic Arts Phenomic. His first contact with cocos2d was in 2009, when he cofounded an aspiring iOS games start-up company called Fun Armada. He loves to teach and enable other game developers so that they can work smarter, not harder. Occasionally you'll find him strolling around in the lush vineyards near his domicile at daytime, and the desert of Nevada at night, collecting bottle caps.

With his knowledge in both game and tool development, his products TexturePacker and PhysicsEditor quickly became essential development tools for any cocos2d user.
