This is an attempt at creating an AI to play flappy bird using java The AI learns using a simple genetic algorithm that implements concepts like crossing over and mutations to several neural networks
This project was inspired by Code Bullet and The Coding Train
Introduction to Genetic Algorithms was a great article which helped a lot with developing the genetic algorithm
This project was done mostly from scratch without the use of any external libraries like TensorFlow

Then there's the NeuralNetwork.java class which implements the neural networks and contains methods like predict that make the bird decide to jump or not
After that, there are the higher-level classes that represent the objects seen on the screen. These classes are Pipe.java Base.java and Bird.java
Finally, there is the highest level class mainWindow.java which contains the game loop and the logic for the genetic algorithm
