Java 7 for Absolute Beginners

CHAPTER 12 ■ VIDEO GAMES

As you can tell from the score, I hit four 10-point targets and one 25-point target before I took the

screen shot. I find the back row to be hard to hit, but it's supposed to be that way, so I guess that's a

good sign.

The ShootingGallery game consists of six classes:

• ShootingGallery defines and manages the user interface.


• ShootingGalleryPanel manages the playing area and contains the game loop.


• ShootingGalleryShooter manages the cursor.


• ShootingGalleryTargetRow manages an individual row of targets.


• ShootingGalleryTarget manages an individual target.


• ShootingGallerySprites manages the sprites used by the game.
