Will Goldstone's Unity Game Development Essentials</a> (UGDE) has arrived. It's the first book about the [...] Unity Game Engine</a> by the person whose videos were the first and most comprehensive Unity videos to date. Will also runs [...] and [...] is a crisp and detailed primer into the powerful Unity engine, 3D programing and game development all at once. Will shares his hard-earned insight and productivity tips as he guides you through learning the Unity IDE. In the early chapters you will learn the various tools available for developing realistic terrains complete with varied trees and grass. You'll take a deep dive into the First Person Controller and its components including the CharacterController. As Will puts it, "If you know how something is put together then you're able to fix it when something goes wrong".
One of my favorite parts of the book is the coverage of Collision detection. You first use colliders, with an initial examination of "isTrigger" then use Raycasting finally followed by a deeper discussion of the role of "isTrigger". This is reviewed and summarized in the section of the book that made crystal clear the previously elusive decision-making algorithm between OnCollisionEnter(), OnTriggerEnter() and RayCasting.
My only complaint about this book is that I wish it could have gone on to some of the more advanced topics. I've read tutorials about physics and springs, and animation but the clarity that Unity Game Development Essentials provides is unmatched and I would love to be as comfortable in those advanced topics as this book has made me with the topics covered. On another note- the clarity of this book and the thorough coverage of a standard set of approaches sets expectations. As this book get more well deserved circulation asking a question that is explained within might earn someone a serving of RTFM. I wish I could have taken the 3 short days that it took me to read this book several months and many long fruitless and error filled nights ago. The first book in the Unity Game Development arena sets the bar high.
If you're a Flash developer interested in 3D in Actionscript you may also want to read Papervision3D Essentials by Paul Tondeur. It's a great book to ease the transition into 3D thinking and provides a lot of information that applies equally to 3D development in Unity.
DISCLOSURE: I Would like to thank Packt Publishing for providing me with a copy of Unity Game Development Essentials for the purpose of reviewing the book.Unity Game Development Essentials
