Currently I have made a flash/as3 Snake game which I want to somehow make it online. So that players can all play together online at the same time.
But my question is, how can I get the informations of the other players? To the players game?
Like when someone move down/up/left or right, how can I get that to show on the other players screen?
You’ll need a server that all players are connected to, either via persistent Socket or RTMP connection. Basically your SWF sends information about the players move to the server, which then passes it to all the other connected players.
You can either build such a server by your own, or use existing technoligies like for example FMS, SmartFox or Red5 (here you can find some more).
