Unity in Action: A top-notch how-to guide for game developers – #gamedev #programming

Unity in Action

Joseph Hocking

Manning – paperback

Unity, the cross-platform game development environment, is easy to download and get running. But it definitely is not easy to learn without some help.

Fortunately, Joe Hocking’s Unity in Action makes it reasonably straightforward to learn how to develop games in 3D, as well as with Unity’s new 2D capabilities. The book takes the reader from “Hello, World” all the way to “Putting the parts together into a complete game” and then “Deploying your game to players’ devices.”

Even with this fine book, however, game development can be hard and complicated work. There are many different elements to consider, such as “Adding enemies and projectiles to the 3D game”, “Developing graphics for your game”, “Adding interactive devices and items within the game,” and putting sound effects and music into your game. Hocking’s book does a good job of showing how to handle these tasks, plus many more.

You may have heard Unity described as a game development environment where you don’t have to know how to program. Yes, you might be able to create some games without programming skills. But, “to produce commercial titles” using Unity, you definitely need some programming experience, Hocking emphasizes. In this case, you should have some knowledge of C#, but a background in some other object-oriented (OO) programming language will be helpful if you are new to C#, he adds.

Hocking’s book has many examples, illustrations, headings and subheadings. But step-by-step listings are sparse. Therefore, be prepared to read the text closely and, if necessary, develop lists of steps yourself. There is nothing wrong with this approach, and it is not really a criticism of the book. Game development, after all, is not something that you can, nor should, just dive into and speed through, step by step. It requires a lot of careful planning and thought before you start.

Unity in Action wastes no time. It gets right to the essential stuff you need to know. And it can get you into action reasonably fast as a game developer. But “reasonably fast” in this case must be defined by how quickly you personally can learn to handle Unity, plus the myriad tasks of planning, creating, testing, revising and distributing a game.

Realm of Racket: Learn to Program, One Game at a Time – #Racket #game #programming #bookreview

Realm of Racket
Learn to Program, One Game at a Time!

Matthias Felleisen, David Van Horn, Conrad Barski, M.D., Forrest Bice, Rose DeMaio, Spencer Florence, Feng-Yun Mimi Lin, Scott Lindeman, Nicole Nussbaum, Eric Peterson, and Ryan Plessner
(No Starch Press – paperback, Kindle)

Formerly known as PLT Scheme, Racket is an offshoot of the Lisp/Scheme family of programming languages. (Lisp, which was first specified in 1958, is the second-oldest high-level programming language, behind FORTRAN).

The (numerous) authors of this 294-page book call Racket “a friendly mutation of Lisp” and tout it as “perfect for all, from those who want to launch their education in computer science to those looking to expand their knowledge and experience in programming.”

Lisp has a long learning curve, so the writers have taken special pains to try to make Racket (“a weird-looking programming language,” they concede) approachable and fun by using comics and games built from short code examples.

Their well-written book is aimed at college freshmen readers. But they emphasize “that doesn’t mean you should drop this book if you are a sophomore or an industry professional.” Nor if you are still in high school or simply like to tinker with programming languages for fun and challenge.

“Regardless of your programming background,” they state, “many of the topics in this book will be new to you, and much of what you’ve learned before will appear in a new light.”

Realm of Racket is structured so that you start out programming very simple games and gradually tackle games that are more complex, while learning about such topics as functions, recursion, lambda, lists, structures, loops, testing, and more.

If you are interested in developing special-purpose computer languages that require specific knowledge of specialized fields, Realm of Racket’s  final chapter briefly delves into the field of language engineering. It notes that Racket “makes it particularly easy to create new programming languages, including special-purpose languages.”

Not surprisingly, some people who program in Racket call themselves Racketeers. The open source language and its program development environment (PDE), DrRacket (“Doctor Racket”), can be downloaded from http://racket-lang.org. “Racket can run on Windows, Mac, and *nix* systems,” the authors note.

Realm of Racket can be a fun, challenging book for computer-savvy teens nearing the end of high school or in their first years of college to study computer science or gaming. Younger readers likely won’t stick with it unless they have some helpful, patient guidance from knowledgeable older siblings or adults. Wait until they’ve gotten reasonably good at another language, such as Python, Ruby, C#, or Java, first.

Designing Games – A well-written, comprehensive guide to video game engineering – #bookreview


Designing Games
A Guide to Engineering Experiences
Tynan Sylvester
(O’Reilly – paperback, Kindle)

If you design video games, if you hope to become a game creator, or if you work for a company whose lifeblood is creating and maintaining successful video games, you need to read this excellent book.

 Tynan Sylvester provides a comprehensive overview of the design processes that are the heart of successful games. And he describes the day-to-day actions necessary to keep game projects on track to completion.

“A game can’t just generate any old string of events, because most events aren’t worth caring about,” Sylvester contends. He is a veteran designer who has worked on everything from independently produced games to big-studio blockbuster games. “For a game to hold attention, those events must provoke blood-pumping human emotion. When the generated events provoke pride, hilarity, awe, or terror, the game works.”

Unlike screenwriters, novelists, or choreographers, game designers do not focus on creating events, Sylvester explains. “Instead of authoring events,  we design mechanics [the rules for how a game works]. Those mechanics then generate events during play.”

In his view, “The hard part of game design is not physically implementing the game. It is inventing and refining knowledge about the design.” And successful game creation involves “inventing mechanics, fiction, art, and technology that interconnect into a powerful engine of experience.”

His 405-page book also shows why you should not try to spell out everything up front before beginning work on a new game. It is too easy to overplan, he emphasizes. But it is also easy to underplan. So you should aim for a process in the middle: iteration, “the practice of making short-range plans, implementing them, testing them, and repeating.” And that loop-like process is applied not just to the overall game. “We can iterate on a level, a tool, or an interface. On larger teams, there should be many different iteration loops running at the same time.”

According to news accounts emerging from the recent Game Developers Conference in San Francisco, much of the video game creation business is now gravitating toward independent developers and game companies with 10 or fewer employees. And the main focus within that movement is on creating games for tablet computers and smartphones–platforms with lower barriers to entry. But powerful new video game consoles are expected to appear soon, and they likely will drive the creation of new games, as well as upgrades for some successful existing games.

Whether you work alone, in a small shop, or on intercontinental game-development teams within big companies, you can learn important insights, processes, and skills from Tynan Sylvester’s Designing Games.  And if you are now in the process of trying to find a design job somewhere in the video game industry, you definitely need to read it.

Enterprise Games – How to build a better 21st-century business with game mechanics – #business #bookreview

Enterprise Games: Using Game Mechanics to Build a Better Business
Michael Hugos
(O’Reilly, paperbackKindle)

Can 21st-century games and gamers attack and destroy the top-down, assembly-line thinking that still keeps many businesses firmly rooted in the previous century?

 Michael Hugos’ compelling new book makes a solid case that they can. Game mechanics, he argues, can reshape how workers work, how organizations are managed, and how business goals get accomplished in today’s volatile global economy.

“Games and the associated technology we currently refer to as video games offer us more than just a diversion and escape from difficult times,” contends Hugos. “They offer us field-tested models to use for organizing companies and performing complex and creative tasks. They offer clear and compelling examples for how people can work together, build their careers, and earn a living in rapidly changing and unpredictable environments.”

Hugos, principal at the Center for Systems Innovation, offers his well-written views in a 199-page book “loosely divided into three parts.”

Part One focuses on “ideas and case studies to illustrate how games can provide operating models to follow for redesigning work.”

Part Two presents “a discussion of games and game mechanics that are relevant to the way work is done.” He includes “specific examples, pictures, and case studies to show how game techniques and technologies can be applied to the design of new business systems and workflows.”

Part Three “describes business and social impacts of combining technology from video games with in-house corporate systems, consumer technology, and cloud computing. The book concludes with a discussion about where this is all going and what it might mean for the future of work.”

During the coming months, Enterprise Games may spur many discussions and arguments at all levels of enterprise. And these may lead to some business-model reorganizations not only in Corporate America but elsewhere in the interconnected global economy.

For these changes to happen, however, many company leaders will have to stop thinking “top down” and learn to adapt “the four traits of a game…goal, rules, feedback system, and voluntary participation” to how they to structure and operate a business.

“We all have a sense of what a game is,” Hugos notes. But most of us also have been taught that “play” is not “work.” Enterprise Games shows how the two concepts can be brought together in ways that can make companies more competitive and more profitable in these uncertain times.
