Marathon—as opposed to what I call a Hackathon—is a small app created in order to apply skills learned in a chapter. It must be a little working mock app for real world applications.
It must be working, have tests, and tutorials so that others can use it as a learning tool, and so the Marathon developer can use it for interviews or job applications. It must be extendable to MVP and eventually can be deployed in production for commercial purposes.
Why Marathons? I have been invited to Hackathons on Haskell Plutus but did not have the background to compete with other developers who had done Haskell for years, and I lost. It alienated me. A Marathon, like common athletics marathons, is a team/group coding exercise as opposed to uneven or unfair competition. All Coxygen Haskell Marathon participants must be rewarded, and this helps prepare them for Hackathons.
A fun and extensible bouncing ball and shooter game written in Haskell, using the Gloss library for graphics and animation.
- Multiple bouncing balls with random motion and wall collisions
- Keyboard-controlled shooter that can move, rotate, and fire bullets
- Customizable environment: window size, ball count, ball speed, etc.
- Optional trajectory logging

- GHC (Glasgow Haskell Compiler) >= 8.0
- Cabal >= 2.4
- Gloss package
- BouncingBalls
Clone the repository:
git clone <your-repo-url>cd BouncingBall
Install dependencies:
cabal update cabal install --only-dependencies
Build the project:
cabal build
From Cabal:
cabal run
Or directly with GHC:
cd src ghc -isrc Main.hs -o bouncingball ./bouncingballCustomize your session: At startup, the game will prompt you to set window size, ball size, speed, count, and other parameters.
To run all tests:
cabal test# Or manually:cdtest
ghc -itest -isrc AllTests.hs -o runtests
./runtests- Arrow keys (
←,→): Move/rotate the shooter - Space: Shoot a bullet
- Q or window close: Exit the game
All major logic is organized in modules within src/Animation/.
See the tutorials for each module to understand or extend each component!
- sounds: bullets fired, exploding balls hit by bullets, stage and levels changing
- dashboard with counters and scores
- enemies and hurdles
- props changes
- distributed peer to peer game
- add hydra technologies
- ada incentives and betting
- blockchain Cardano features
- etc… move from learning to earning ADA!
