His version could only get the players list, so I finished it and it is now possible to read m more info the status protocol gives about the server (I have not implemented REQUEST_PLAYER_STATUS_INFO which is for looking if a certain player is online). (credits for the base code for Gesior, ofc).
You can change the
This is a sample output:
This script is more like a prof of conecpt, it helped me understand this protocol better and I hope it helps you aswell. I haven't been able to parse the software info response, I also haven't looked deep into it, it can probably something simple to fix idk.
