What you need for this book

Throughout this book, we will work within the Unity 3D game engine, which you can download from http://unity3d.com/unity/download/. The projects were created using Version 4.5.3, but the project should work with minimal changes, with differences between this version and the 4.6 beta being pointed out when they occur. In Chapter 9, Creating GUIs Part 2 – Unity's New GUI System, since we are using the new GUI system, we will be using the Unity beta version, which can be downloaded from http://unity3d.com/unity/beta/4.6.

For the sake of simplicity, we will assume that you are working on a Windows-powered computer. Though Unity allows you to code in either C#, Boo, or UnityScript; for this book, we will be using C#.
