Karma is a machine learning necto level bot in rlgym ppo. This bot was trained and created by me (kuenec).
This repo made by zealan will cover everything from installaing dependencies to creating and making your own bot: Zealan Guide.
My example.py already has code implemented in it to use Zealans 'RocketSimVis' so you will be able to see how your bot plays in a virtually created environment while it trains. This is not needed but if you want to see your bot play you can download it here: Zealan Guide.
