Michelle Menard and Bryan Wagstaff. Game Development with Unity: Second Edition. Boston, Cengage Learning PTR, 2015.

Revising this book has been quite an adventure. When Emi Smith of Cengage Learning contacted me about this project, I felt I could do the job easily. After all, I was comfortable with Unity, had a list of game credits, and had helped edit books in the past. It certainly loomed larger as time passed. The months revising this book and bringing it up to date have been an enjoyable challenge, and I could not have done it alone. I need to thank the Unity team for their steady stream of updates and providing such a great engine. Unity is updated frequently. The first edition was written against early editions of the 3.x Unity series. Revising it meant every sentence needed to be verified against the current version, every screenshot updated, and every line of code validated. On finding any place that Unity’s behavior had changed, sections needed to be rewritten. Unity’s animation engine and particle system had been completely replaced, so the book required effort there. The number of supported platforms had grown from three in the first edition to over 15 potential platforms today. Even so, the book is already out of date. As this revision nears completion, the 5.x series is nearly here and will probably be released before this book. Thanks to all of you who continue to improve the tools.
