Am I allowed to do something like this? Or, how do I manage 2 packets at once?
heinrich5991 2022-11-02 00:09:36Z
in that function you get one message. the type says which message it is
00:10
you can't cast the void * to messages other than the one that was specified by the type

It's impossible with the way we structure the code rn, but you can host multiple CGameWorlds in one server by selectively snapping. Or maybe add a new redirect message so the client gets redirected to the new server

I did some profiling recently and the result was that recvfrom was the main culprit (#1996), optimising anything else would probably not bring great returns

clonning ddnet repo for mods are kinda issue, you can just download and upload it again, its kinda disturbing. You can make only one fork of repo, its not a solution, so maybe making ddnet a template repo a good idea, or maybe other repo with only stable vesions. I created repo like this on my own and its incredibly handy to use https://github.com/AnimeIdiots/ddnet-template/

for 64p server it would probs be worth to make the gamecore not doing O(n²) all the time also we use distance, instead of distance_squared (which COULD cause physic changes), but purely mathematically, isnt different
