I am building a trading card game and have some of the basic programming done already. I made a Deck Editor GUI where someone can choose which cards to put in their decks, a chat lobby GUI, and a generic Game Play GUI.
Once a player logs into the game (with username and password), I want the program to display different information on that persons screen specific to their username. Once they start a game they will also, obviously, need to see a different screen than their opponent.
Does anyone have any suggestions or can anyone point me in the right direction on how to make the game multi-player across the internet?
Question #2: In order to make my game multi-player, is there anything I need beyond the program? For example, a special kind of website or internet service?
