For our game we need a ball, a goal, and a court floor. The BallGameArt assets (in the package for this chapter available from the publisher) provide a variety of ball game graphics, which we will integrate into the project later. For now, we'll first make a simple set of white-box graphics to use during development. We'll call this game BoxBall.
White box, or block design, is a design method used in early stages of game level design, using simple geometric forms. By omitting details that do not affect object behavior and game mechanics, white box design affords us a quick way to focus on more critical aspects of the game and then come back to the visual design later.
