Modular Genetic Algorithm Neural Network

A complex game system which involves a self learning AI. This is implemented into a racing game as a preview of the system.

Many third party libraries have implemented simple neural networks such as Keras and TensorFlow but I wanted to create my own. This custom neural network is designed to be imported to any Unity project as a package and can be used simply by adding a few lines of code. This is targeted more towards other programmers as the functionality behind the AI will be changed depending on what it is needed for.

This neural network uses evolution as its basis. The hardest part about teaching an AI is getting the right parameters for the fitness score. You can check out a more indepth breakdown on the next page.

The game is a simple racing game where the player uses the direction keys to move around the race course. You are pitted against several AI that have been trained to drive some courses. The AI uses raycasts to determine the distance between the walls and itself to drive as fast as possible.

This is a short 5 min video of a learning process.
