I want to thank my brother, Chris, and my wife, Hannah, for
being supportive and patient with me as I spent my free time
and weekends away from them to work on this book.
On that same note, as always, I also want to thank Samir Abou
Samra and Elie Hosry for their support and encouragement
while working on this book as well as the rest of the DigiPen
Singapore staff.
Last but not least, I'd love to thank my family as well as my
parents, Joseph and Sandra, who took me seriously when I
told them I wanted to make games.
About the Reviewers
Gary Riches is a senior software engineer and long-standing member of the iOS
developer community. He has a keen interest in emerging technologies and is
currently exploring what's possible with virtual reality.
Having worked as a software engineer for 16 years, he has had the opportunity to
present his work worldwide at technology events, such as CES, Electronica, and
Apps World.
He is the author of Ouya Unity Game Development, Packt Publishing and co-author
of You can make an APP, Future Publishing.
When not building apps for clients, he also creates games and educational experiences
for his own company, Bouncing Ball Games. The titles so far include Aztec Antics,

Adam Single is a husband, father, professional developer, indie developer, lover
of music, and gamer. He's the coder for 7bit Hero; a programmer on the tech team at
Real Serious Games in Brisbane, Australia; cofounder, programmer, and codesigner
at Sly Budgie; and co-organizer of the Game Technology Brisbane meetup.
Since entering the professional game development industry in 2011, Adam has
worked on numerous mobile games, including the Android hit Photon and a
pre-installed game for specific Disney Japan handsets. He's been the programmer on a
team that created a huge, interactive display at Queensland University of Technology's
amazing multitouch screen installation, The Cube, as a part of Australia's first Digital
Writing Residency and worked on a team at Real Serious Games creating large-scale,
interactive simulations for the mining and construction industries. All of this has been
done using the Unity game engine.
Adam has a passion for the unique and engaging possibilities inherent in modern
technology. When he's not working on exciting new game mechanics for Sly Budgie,
he's experimenting with "homemade VR" using mobile phone technology and pushing
the exciting ideas behind 7bit Hero's live music/multiplayer game interaction down
whichever fascinating path it may lead.
