Teeworlds is a great multiplayer game and I would love to see it portable. The game puts setting files in %USERPROFILE%/Application Data/Teeworlds. I tried to make it portable myself but I couldn't get it to work so I hope one will have better luck.
Teeworlds is open source and it can be found on http://teeworlds.com
looks like a pretty cool game. i'll look at it, unless someone else really wants to take it.
Does look really cool. Go for it.
ok, i got it working. it now redirects the setting folder to the local Data folder. a couple things though. i don't know if i should let it keep the maps folder of downloaded maps or delete them on exit (it's an online game so it downloads maps when it needs them). also i don't know if teeworlds_srv.exe is needed; i guess it's to set up a server but it didn't work for me and most people aren't going to set up a server from their portable game (mby if they want to do a lan though). BTW, the game is pretty fun.
Leave the server. It requires writing some configuration file to run but it shouldn't bother you too much. I would also vote for leaving downloaded maps. One can manually clear maps folder from time to time and this could speed up loading maps a bit.
Progress Update:
initially making the game portable was easy but it's taking me a while to write code to have the game select the proper resolution. Luckily i had code from secret maryo chronicles to base this on. I'm going to have it delete any downloaded maps in order to save space because the maps only take a couple seconds to download anyways. I'm initially leaving the server exe off since most people won't know how to configure it. i plan on writing a small gui to make selections to set up a LAN game later on. Expect a release probably tonight maybe tomorrow.
