In-Depth Information
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.
