I trained an AI to navigate through asteroids in Godot 4.6 using reinforcement learning

Hey! Been working on this in the past two months. The AI (Rookie) learns to fly through asteroid fields using PPO, no scripted movement, just raw thrust/rotation inputs and a reward system. Everything built in Godot 4.6, models in Blender.

I’ve experimented with RL in Godot before, but this is the first time I actually got it to work well enough to be worth showing. The reward shaping process was so fun and interesting that it inspired me to start a video series about machine learning in Godot using RL Agents.

This is the first episode; any feedback or questions are welcome!
