Chapter 5 ■ An Introduction to Game Design: Concepts, Multimedia, and Using Scene Builder debugged. A significant opportunity also exists for developing new types of game genres that use a hybrid combination of static and dynamic game play in creative new ways that have never before been seen. I am working on a few of these myself! Because this is a Java 8 programming title, I am going to approach everything from this standpoint, which happens to be a great way to divide games into discrete categories (static, dynamic, hybrid), so let’s cover the static (fixed graphics), turn-based games first. These include board games, puzzle games, knowledge games, memory games, and strategy games, all of which should not be underestimated in their popularity and marketability. The thing that is cool about static games is that they can be just as fun to play as dynamic games and have significantly less processing overhead, as they do not have to achieve the 60FPS real-time processing target to achieve smooth, professional game play. This is because the nature of the game is not predicated on motion at all, but rather on making the right strategic move, but only when it is your turn to do so. There can be some forms of collision detection involved in static games regarding which game piece has been moved to a given location on the gameboard or playing surface; however, there is no danger of overloading the processor with collision detection, because the rest of the game board is static, with the exception of the one piece that is being strategically moved during that particular player’s turn. The processing logic for strategy games is more strategy logic–based programming, geared toward allowing the players to achieve an end win, given the right sequence of moves, whereas the dynamic game programming logic looks more at what collisions are taking place between game sprites. Dynamic games are focused on point score, dodging projectiles, finding treasures, completing level objectives, and killing enemies. Complicated strategy games with lots of interrelated rules, such as chess, are likely to have far more programming logic routines than dynamic games. Yet, because the execution of the code is not as time sensitive, the resulting game play will be smooth, no matter how powerful the platform and CPU are. Of course, the game rule set logic must be flawless for this type of game to truly be professional, so, in the end, both static and dynamic games are difficult to code, albeit for different reasons. Dynamic games could be termed action games or arcade games and include a lot of movement on the display screen. These highly dynamic games almost always involve shooting things, such as in the first-person shooter (e.g., Doom, Half-Life) as well as in the third-person shooter (Resident Evil, Grand Theft Auto) genres, or stealing things, or evading things. There is also the obstacle course navigation paradigm, commonly seen in platform games, such as Donkey Kong and Super Mario. It is important to note that any genre of game can be produced using 2D or 3D graphics and assets or even a combination of 2D and 3D assets, which, as I pointed out in Chapter 4, is allowed by JavaFX. There are so many popular game types that there is always the opportunity to create an entirely new genre of game by using a hybrid approach of a static (strategic) game type and a dynamic (action) game type. Game Design Assets: New Media Content Concepts One of the most powerful tools you have to make your game highly professional and desirable to buyers is the multimedia production software that you downloaded and installed back in Chapter 1. Before I go any further, I need to spend some time providing you with foundational knowledge regarding four primary types of new media assets that are supported in Java 8, using the JavaFX 8 multimedia engine: digital images, used for sprites, background imagery, and 2D animation; vector shapes, used in 2D illustration, collision detection, 3D objects, paths, and curves; digital audio, used for sound effects, narration, and background music; and digital video, used in games for animated background loops (birds flying through the sky, drifting clouds, and so on) once highly optimized. As illustrated in Figure 5-1, these four major genres, or areas, are all installed via the JavaFX Scene Graph, using packages that I described in Chapter 4. Some of the primary classes that will be used are ImageView, AudioClip, Media, MediaView, MediaPlayer, Line, Arc, Path, Circle, Rectangle, Box, Sphere, Cylinder, Shape3D, Mesh, and MeshView. www.it-ebooks.info 105
Chapter 5 ■ An Introduction to Game Design: Concepts, Multimedia, and Using Scene Builder Figure 5-1. How new media assets are implemented, using Scene Graph through the JavaFX API in Java 8 via NetBeans Because you need to have a technical foundation before using any of these types of new media elements in a Java 8 game design and programming pipeline, I am going to go over basic concepts for each of these four new media areas, beginning with digital imaging and vector illustration. Digital Imaging Concepts: Resolution, Color Depth, Alpha, Layers JavaFX (and therefore Java8) supports a significant number of popular digital imaging file (data) formats, which gives game designers a ton of flexibility. Some of these have been around forever, such as CompuServe’s graphics interchange format (GIF) and the Joint Photographic Experts Group (JPEG) format. Some JavaFX graphics file formats are more modern, such as portable network graphics (PNG; pronounced “ping”), which is the file format that you will be using for your games, as it yields the highest quality level and supports image compositing. All these mainstream digital image file formats supported in Java are also supported in HTML5 browsers, and because Java applications can be used with HTML applications and web sites, this is a very logical synergy indeed! The oldest CompuServe GIF format is the lossless digital image file format. It is termed lossless because it does not throw away image data to achieve better compression results. The GIF compression algorithm is not as refined (powerful) as that of the PNG format, and GIF only supports indexed color, which is how it obtains its compression (smaller file size). If your game image assets are already created with the GIF format, you will be able to use them with no problem (other than a less efficient image compression algorithm and no compositing capability) with your Java 8 game applications. The most popular digital imaging file format that Java 8 (JavaFX) supports is JPEG, which uses a “truecolor” color depth, instead of an indexed color depth, as well as what is termed lossy digital image compression, in which the compression algorithm “throws away” image data so that it can achieve a smaller file size (the image data are lost forever, unless you are smart and save your original image!). If you magnify a JPEG image after compression, you will see a discolored area (effect) that clearly was not present in the original imagery. The degraded area or areas in the image are commonly referred to as compression artifacts. This will only occur in lossy image compression and is common with JPEG (and Moving Picture Experts Group [MPEG]) compression. 106 www.it-ebooks.info
