Unity in Action teaches you how to write and deploy games. You'll master the Unity toolset from the ground up, adding the skills you need to go from application coder to game developer. Based on Unity version 5.

About the book
This book helps readers build successful games with the Unity game development platform. You will use the powerful C# language, Unity´s intuitive workflow tools, and a state-of-the-art rendering engine to build and deploy mobile, desktop, and console games. Unity´s single codebase approach minimizes inefficient switching among development tools and concentrates your attention on making great interactive experiences.

Unity in Action teaches you how to write and deploy games. You´ll master the Unity toolset from the ground up, adding the skills you need to go from application coder to game developer. Each sample project illuminates specifi c Unity features and game development strategies. As you read and practice, you'll build up a well-rounded skill set for creating graphically driven 2D and 3D game applications.
