An application of NEAT in flappy bird

FlappyBird played by NEAT. Every bird has its own ANN and a fitness score that is measured by distance/time passed. For each generation top 50% of population is preserved and possibly mutated while the rest is discarded. Mutations can change ANN of each bird in various ways.

git clone https://github.com/dulex123/jj-farm

java -Dsun.java2d.opengl=true game.FlappyBird

Notes

  • It is not guaranteed that birds will evolve to play the game successfuly
  • If you are interested in NEAT take a look at these books:
