A word about the third edition

As I sit here in my luxurious velvet smoking jacket, taking a long draw on a pipe, and admiring the various stuffed hunting trophies around the room in an attitude of quiet contemplation, it dawns on me that I don't smoke or advocate sport-hunting, and that I have no idea what I'm doing in this room. The jacket, however, is quite nice. I think I'll keep it.

It's wonderful to see that this book, one of the very first instructional guides about Unity 3D on the market, has withstood both the test of time, and Unity Technologies' relentless release schedule. Owing to the rapid pace of technology, many things have changed in a few short years. C# has largely overtaken UnityScript as a preferred language; to that end, all of the code in the book has been supplemented with a C# translation, including notes on how to perform that translation yourself for past and future projects.

In the time since the first edition, computers have increasingly become our evil, dominating overlords. With that in mind, the third edition includes two bonus chapters that teach you how to build a two-player game, and then how to program the computer to act as the merciless second player who never loses. That chapter also contains information on how to make the computer player lose, which I present as secret codified data to be used by the resistance movement during the inevitable machine uprising. Stay ever vigilant!
