I see many issues with this. CS2 is not an HLDS game so posting in this subforum is not appropriate. An author who admits that they haven't even tested their own code despite officially releasing it at all probably shouldn't be trusted. Also, whatever API they are using is not one that is supported in by this community so you'd be better off finding the community that does support that. In fact, you can report issues in that GitHub repository directly.
