I have put a pull request on the GunGame GitHub repo
here which should prevent players on low levels using knife to steal from players on higher levels when the difference between the killer and victim is greater than
KnifeProMaxDiff.
JavaScript port of the problem/fix:
https://jsfiddle.net/zovmn5rs/1/
I'm not sure if it is a bug that should be fixed but I did it as new feature with a config variable so as not to change the behaviour of existing servers.
The problem I am trying to solve is cheaters with knifebots and players with poor etiquette coming in near the end of the round using knife to level-up by stealing from people on scopes, etc. and achieving near-parity without actually playing GunGame at all. Obviously doesn't apply to all server configurations but applies to the one that I like to play on.
I haven't compiled or tested the feature -- hoping someone who already has a server set-up with GGDM might like to do this?
