Hello,

I’m currently working on training agents capable of navigating from point A to point B while avoiding obstacles. Currently, I’m employing Lane Tracing by Channel to generate an array of location and distance values describing each ray, simulating the agent’s vision. Subsequently, I construct a static array observation using this data. Is this the correct way to do this kind of thing??

Thank you!

Yes, that’s exactly how you would do it!
