Hey, I need help figuring out my rewards system for my RL Model

Hey I’m pretty new to creating AI and stuff, and at the moment I’m working on an RL AI that should play a fairly simple platform, it has just 3 inputs, right left and jump.

I got everything working, capture screen make it into a matrix so the Agent can see it I got the outputs working but I don’t managed to get the rewards system to work. After a few iterations the agent stops moving, just jumps or walks right in to a wall, even if I punish the agent if it moves to the left it ends up running against the left wall.

Pleas help I can’t figure it out
