He started to develop on Amstrad CPC464 with the BASIC language when he was 7. He learned later Visual Basic 3/4, then VB.NET, and C#. For several years, until the end of his study, he developed and maintained several PHP and ASP.NET e-business websites. After his graduation he continued to learn more and more about software like Architecture and Project management, always acquiring new skills. Julien was at work talking with a colleague in August 2009 and after discovering the high potential of iPhone games and softwares he decided to find an improved game engine allowing him to concentrate only on the main purpose of the game—developing a game and not a game engine. After trying two other game engines, his choice was Unity3D thanks to its compatibility with C# and its high frame rate performance on iPhone. In addition to his main work, he opened iXGaminG.com as a self-employed business in December 2010. This small studio specialized in advergaming and casual gaming using Unity3D. I would like to thank my wife for allowing me to take some time in reviewing books on my computer. I would also like to thank Frederic for all the work we completed together with Unity. So, I do not forget to thank all current Unity Asset Store customers who are using my published assets and scripts. Then I would like to thank my family, my friends, and colleagues, including Romain, Nicolas, Patrick I, Chang D, Alexandre, Philippe S, Philippe G, Marie-Helene D, Corinne F, Mathieu N, Christophe B, Christophe P, and Fabrice G, who knows me as an Apple(c) addict. www.it-ebooks.info Clifford Peters is currently a college student pursuing a degree in Computer Science.
