I'm looking for the simplest way to create AS3 multiplayer game. I've made few as3 games, so I basically know the language and its limits. I've never been into server-like coding.
I want to create a simple game, just like my previous ones, but this time with multiplayer connections. I don't want p2p connection, more likely I'm looking for server/room hosting.
About the game: Something similiar to hybrid of casual mugen game and a 2d-platform shooters (watch TeeWorlds, Soldat). I don't need large database, eventually I could use some xml saved files for that purpose (no need to keep real-time data management). In the first throw I don't need accounts for that game, more like open access, same for everyone.
What are your suggestions? Which engine/enviroment/modules could I use to bring AS3 to multiplayer game? And any tutorials how to start?
