Multiplayer gamesThis functionality is only available in the Standard Edition of GameMaker.
Playing games against the computer is fun. But playing games against other human players can be even more fun. It is also relatively easy to make such games because you don't have to implement complicated computer opponent AI. You can of course sit with two players behind the same monitor and use different keys or other input devices, but it is a lot more interesting when each player can sit behind his own computer. Or even better, one player sits on the other side of the ocean. GameMaker has multiplayer support. Please realize that creating effective multiplayer games that synchronize well and have no latency is a difficult task. This chapter gives a brief description of the possibilities. On the website a tutorial is available with more information.
