Besides making my indie, I'm planning on a server multiplayer game. I'm new to networking and barely know anything how server works. If someone able to give out some code or helping me out making both hoster and player. That would be very appreciated.
EDIT: to be more exact. I just need some thing 2 player co-op and 1v1 game. Like match making with random player.
1v1 type of games can be done with decent speeds using what game maker has to offer and with the DLL support already available, you'll do just fine. If you want to use 39DLL, I remember playing around with BlaXun's tutorials and found it pretty easy to use. But like other's have said, we do have alternatives that claim to be more efficient.
