About the Author
Michael Hartlef has been into game development for a long long me, starng in 1984,
at the early age of 18, with this great hobby called developing computer games, on the

Commodore C64. Aer developing for this machine, he has worked on most other well-known
computers, such as the Amiga 1000 and 500, the Atari 1024 STFm, and of course various PCs.
These days it is mostly his iMac that he uses.
Over the years, he has become very knowledgeable about general and specic concepts
for developing games and has worked on a large range of game development tools/
programming languages, such as thinBasic, Delphi, 3D GameStudio, Blitz3D, BlitzMax,
DarkBasic Pro, App Game Kit (AGK), Corona SDK, and of course, Monkey! Besides working on
games, Michael has developed various add-ons for tools such as command library extensions
and programming editors.
During the day, Michael works for a ulity company where he maintains the billing system
(SAP IS-U). Michael is also the founder of an independent game developer startup called
Whitesky Games (
). There, he spends a lot of his spare
me working on game development tools (IndeED), add-ons and games for friends and
clients, and his own projects.
First, I'd like to thank my wonderful wife Katherine and my great son Marc
Jusn for having so much paence with me during the me of wring this
book and giving me all the support I needed. Without you guys, I would not
have made it. I love you!

Also, I would like to thank the people at PacktPub for giving me the
opportunity to write this book, which has been a great experience in my
life. Next, I send a big thank you to Jayant Varma from Oz Apps, who hinted
to me that PacktPub was looking for an author for this book. Also, I want to
thank Lee Bardsley from GameLab3D for being my friend and talk buddy.

And nally, a big thank you goes to Mark Sibly, the creator of Monkey, for
providing such an awesome tool for the people and me.
About the Reviewers
Nikolas Kolm has been acve as a Level Designer, World Builder, and Interacve Storyteller

for a long me, in capacies ranging from community Mod projects, to student work, to
indie producon. During this me, he has gathered a lot of experience in dierent editors
and producon sengs, most commonly the Unreal Editor, the NWN2 Toolset, and the
Dragon Age Toolset as well as Game Maker, and recently, Unity 3D.
During his me along with the Mod team responsible for a persistent world server for
Neverwinter Nights 2, Nikolas was responsible for the creaon of interesng areas and levels
for players to traverse and live in, which needed to adhere to a common theme with the rest
of the world, and also had to oer challenges for groups of players out for an adventure.
This included seng up encounters with enemies, seng up the ambient eects, creang
dialogue for scripted encounters, and ensuring that the area supported the environmental
storytelling of the module.
While working on the indie tle AVOID, as Lead Game Designer, Niko also had to ll in as
Level Designer from me to me, which allowed him to pracce his skills with the Unity
editor. It also allowed him to work in a leadership capacity with a team of over 30 other
team members, to experience a complete producon cycle.
His unique background, living in Japan, traveling the world, and studying many cultures and
history, has given him a wealth of experience from which to draw when designing believable
characters, dramac encounters, and immersive worlds.
Meri Morganov has been playing video games for most of her life and has always
wondered what the magic behind them was. She took game programming courses at the
Art Instute of Vancouver to learn more on the topic and worked with big student groups to
make games. From high-level scripng to low-level programming, she worked hard to learn
the art of the trade.
Aer college she has been working on indie projects with friends and small companies. She
loves working in teams and staying in close contact with her teammates to get the job done
right. Unity3D and Visual Studio have been her favorite tools to use.
I'd like to thank my teachers and friends who made it possible for me to
learn such a great skill.
