Maxint R&D / Mbed 2 deprecated RETRO_BallsAndPaddle

Balls & Paddle game for RETRO Pong inspired game featuring multi-directional tilt-sensitive paddle, multiple balls, shrinking ceiling and a bit of gravity.

Balls and Paddle

After doing some work on the Pong mod I decided to put my efforts into making my version object oriented and try to make a generic object-library that could be use for other ball-and-things games. To add some challenges to the gameplay, the following features were added:

  • extra-free additional balls to please the juglers
  • gravity for pulling the ball down to create some dynamic movement
  • directional power-paddle that counters the ball with a bit more speed
  • lowering ceiling to make endless gameplay impossible
