Breakout Variations

Breakout variations

a) Standard Breakout

Control the paddle to move left and right. Get points when the ball hits a brick. Lose points when the ball goes below the paddle.

python schema_games/breakout/play.py StandardBreakout

b) Middle Wall Breakout

When the ball hits the wall in the middle, it rebounds. To hit bricks, the wall must be avoided.

python schema_games/breakout/play.py MiddleWallBreakout

c) Half Negative Breakout

The yellow bricks give negative points when struck by the ball.

python schema_games/breakout/play.py HalfNegativeBreakout

d) Offset Paddle Breakout

The paddle is slightly raised with respect to the standard version.

python schema_games/breakout/play.py OffsetPaddleBreakout

e) Random Target Breakout

The block of bricks randomly moves every time it is struck by the ball.

python schema_games/breakout/play.py RandomTargetBreakout

f) Juggling Breakout

There are three balls and no bricks. The maximum possible score is zero.
