I have this file and I need help understanding a section on it. I’v attached the file from http://www.gotoandplay.it/_articles/multiplayerCentral/. The section I need help on is the following.
mySocket.connect("localhost", 9999)
I think I get the rest. But thats the name and port number right? From what I understand there are alot of ports that can be used. But the name part, should it be soemthing like a IP or computer name or what? Just need some explanation on this part to better understand it so I can get it to work.
