BlackBerry smartphones are not just for business. As it turns out, the
BlackBerry is for gaming, too. We show you how to leverage the
Java Development Environment (based on Java ME)
to design and create fun and sophisticated game applications, from role playing to a Jedi
knight battle. In this book, we give you the professional techniques for
using music, action, graphics for building gorgeous user interfaces, scalable vector
graphics, basic game actions, peer to peer games, role playing games, and more. Along
the journey, you can take what you have learned to create very cool games, such as
Battlin' Light Saber, a toy sports car driving, and the Fox and Hounds GPS game.

Chapter 2. BlackBerry Application Basics
Why are there two types of BlackBerry Java applications? What are all those
crazy files the compiler generated? And most importantly how do I get an
application complied and running on my BlackBerry smartphone? Chapter 2 will
answer all of these questions, plus help you set up a professional build with Ant.
Chapter 3. Game Graphics and Events with MIDP and RIM Classes
Using the classic Maze game as an example, you'll see exactly how the two types
of BlackBerry Java applications differ. You get an in-depth look at how the
lifecycle, events, and graphics work in both cases so you'll be ready to develop
whichever kind is best suited to your game's needs.
Chapter 4. Adding a Professional Look and Feel
Gorgeous graphics are critical for the game experience. To get your game's visual
theme pixel-perfect on every model, BlackBerry gives you the tools, and Chapter 4
explains how to use them.
Chapter 5. Security and Selling Your Game
As much as you love games for their own sake, at the end of the day it's nice
to get paid. In Chapter 5 you'll see how to sell your game on BlackBerry App World
(or on your own site) plus how to apply the cryptography APIs to implement
licensing and Digital Rights Management.
Chapter 6. Swingin' Light Saber
With action, music, sound-effects, colliding game sprites, and even touch-screen
input, Andrew shows you how to put it all together and develop a real game.
Plus BlackBerry's accelerometer lets you wield your saber like a true RIM-i Knight!
The second half of this book takes you beyond the basic games. See how exciting
games can be when you add a little imagination to advanced features like 2 and
3-D graphics, network communications with other players, GPS, and more!
Chapter 7. Play a Live Opponent with SMS
That classic, tiny packet of data sent by the Short Message Service is still
a favorite with users and operators alike. And it's all you need to play a
trans-atlantic game of Checkers with a friend chosen from your BlackBerry
Chapter 8. Using Scalable Vector Graphics
2-D graphics are easy to master and allow you to create surprisingly impressive
effects. Check out Chapter 8's spinning spaceship video and learn the tricks
to create it.
Chapter 9. Creating Role-Playing Games on the Internet
Since Internet everywhere is BlackBerry's strong point, it was practically
born for Massively Multiplayer Online Role-Playing Games (MMORPGs)! Chapter 9
uses Twitter to create a virtual asteroid belt that you can explore and find
real people in their own virtual ships.
