Black Art of Java Game Programming:IntroductionBlack Art of Java Game Programmingby Joel FanSams, Macmillan Computer PublishingISBN: 1571690433 Pub Date: 11/01/96Table of ContentsIntroductionGaming on the Web is the next blockbuster business. Have any doubts? The video game industry,which already eclipses Hollywood in terms of revenue, targets the Web as the next huge growth area.Software developers are busily porting games to the online environment, or developing entirely newones. And numerous popular Web sites, many of which charge fees, are devoted to gameentertainment.With Black Art of Java Game Programming, you’ll learn how to create your own dynamic onlineentertainment using the Java programming language. Java heralds a revolutionary shift in gaming,away from the desktop and into the network. Using Java, you’ll create games that people candownload through the Web and play. Using Java, you’ll enable players from around the world tocompete against one another. As Java enters its maturity, the possibilities of creating innovativeentertainment are endless, and the potential for profit unbounded.This book provides you with the foundations for creating Java games of all types, such as boardgames, video games, and networked/multiplayer games. We recommend that you have some basicknowledge of C, C , or Java before diving in. The underlying thread of this book is that good objectoriented design and good Java games go hand in hand, so we devote the early chapters of the book tocovering and applying object-oriented principles to graphics and games. Once the foundations havebeen laid, we build a wide variety of games. As you will see, game programming is almost a game initself, and once you learn the basics, you’ll be well equipped to write innovative games on your own.OrganizationBlack Art of Java Game Programming is divided into three parts:Part I, Fundamentals of Java Game DevelopmentPart II, Advanced Game and Graphics TechniquesPart III, Game Galleryfile:///D Game%20Programming/index.html (1 von 3) [13.03.2002 13:17:32]

Black Art of Java Game Programming:IntroductionPart I, FundamentalsPart I takes you on a whirlwind tour of Java, graphics, and object-oriented game programming. Thissection is for you if you’re learning Java, if you’re new to object-oriented design, or if you want to seehow to build a game step by step.This is what’s covered in the Fundamentals section:Chapter 1, “Fundamental Java,” delivers a turbocharged introduction to the Java language, the API,and object-oriented design. By the end, you’ll create graphics applets.Chapter 2, “Using Objects for Animation,” shows you how classes, inheritance, and dynamic methodbinding help you animate objects. You’ll also learn about clipping and double-buffering, two basicgraphics techniques.Chapter 3, “Animating Sprites,” teaches you to create a simple abstract class for representing graphicsobjects called sprites. In addition, you’ll learn about interfaces, bitmap animation, and sound.Chapter 4, “Adding Interactivity,” shows you how to create applets that respond in real time to playerinput.Chapter 5, “Building a Video Game,” shows you how to apply what you’ve learned in the first fourchapters to create a shoot-’em-up video game. What you learn here can be applied to creating manyother types of games.Chapter 6, “Extending Your Video Game,” shows you how to take a game that you’ve developed andadd new features to it without starting from scratch.Chapter 7, “Creating Customizable Games with the AWT,” demonstrates how Java’s AbstractWindowing Toolkit allows players to change parameters in your games. What you learn here aboutthe AWT will be applied throughout the rest of the book.Part II, Advanced Game and Graphics TechniquesIn Part II, you’ll learn the skills necessary to bring your games into the next dimension, such asmultithreading, networking and multiplayer techniques, and 3D.Chapter 8, “Implementing a High Score Server on a Network,” takes you through Java’s networkingand GUI facilities, and teaches you to build a high score server for your games.Chapter 9, “Advanced Networking and Multiplayer Gaming Concepts,” illustrates techniques forenabling multiuser game play over the Web. In addition, you’ll deepen your understanding of Java’snetworking capabilities by implementing a chat room.file:///D Game%20Programming/index.html (2 von 3) [13.03.2002 13:17:32]

Black Art of Java Game Programming:IntroductionChapter 10, “Advanced Techniques,” covers features of Java and the Java API that are useful inwriting games and organizing programs.Chapter 11, “Into the Third Dimension,” demonstrates the process of defining, transforming,projecting, and painting three-dimensional models, and builds classes that can be used to make asimple 3D engine.Chapter 12, “Building 3D Applets with App3Dcore,” shows how the App3Dcore (a set of classes)works and how it can be used to develop some simple 3D applets and an advanced 3D game.Part III, Game GalleryIn Part III, you’ll apply the skills you’ve learned in earlier chapters as leading Java game designerstake you step by step through the creation of a wide spectrum of cool games.Chapter 13,“Building the JAVAroids Game,” shows you how to create a Java version of the videogame classic Asteroids.Chapter 14, “Daleks!,” takes you through the creation of an enhanced Java version of a classiccomputer game.Chapter 15, “NetOthello,” builds on your networking skills learned in earlier chapters to create anetworked implementation of the classic game Othello.Chapter 16, “WordQuest,” takes you through the creation of a Java game specifically designed toteach vocabulary, but which could easily be extended to teach a plethora of other concepts,demonstrating Java’s potential as a learning tool.Chapter 17, “The Magic Squares Puzzle,” is an example of a deceptively simple, yet challengingpuzzle game that will delight Rubik’s Cube enthusiasts (and many others).Chapter 18, “The Internet MahJong Server,” demonstrates a software package that allows people toplay the classic Chinese strategy game MahJong with each other online.Chapter 19, “Slider Puzzle,” shows you how to write a Java applet for a simple slider puzzle enhancedwith animation and sound.Chapter 20, “The Game of Worm,” develops a game in which you control the direction of a virtualworm on a rectangular playing surface, collecting treats while avoiding collision with solid objects.Table of Contentsfile:///D Game%20Programming/index.html (3 von 3) [13.03.2002 13:17:32]
