Play with arrow keys. It is really functional because it was tested on two computers.
It is made fully by me. Remix it and create a game with multiplayer. Position broadcast every 0.25 secs! It can't be in real time because it will stop broadcasting and other player's computer won't detect an active player Always check the changing variables. When one of them isn't changing, the player is disconnected. When it stays on 0, there isn't any player connected.
