Our Game's Design
We are not going to assume that everyone who reads this chapter knows of or understands
Atari's classic arcade game Asteroids . So let's start by taking a peek at the Asteroids game-
play elements.
Asteroids ,designed byEdLoggandLyle Rains, wasreleased byAtari in1979.The game pit-
ted a lone triangular two-dimensional vector spaceship (the player ship) against screen after
would enter the screen attempting to destroy the player ship.
All asteroids started the game as large rocks; when they were hit, they would split into two
into two small rocks. The small rocks would simply be destroyed when hit. (Small was the
final size for all asteroids.)
When the player destroyed all the asteroids, a new screen of more and slightly faster asteroids
would appear. This went on until the player exhausted his three ships. At each 10,000-point
score mark, the player was awarded an extra ship.
All of the game objects moved (thrusting, rotating, and/or floating) freely across the entire
screen, which represented a slice of space as a flat plane. When an object went off the side of
the screen, it would reappear on the opposite side, in warp-like fashion.
