Thank you for your reply! Multiplayer class system. I have to save some player lvls somewhere...

I am trying to create a mod that writes some player data into file. I want the file to be updated only when logical server is starting up. As I can see, @SidedProxy affects physical side only, and the file is not created on local server. I've tried to use this way: public static CommonProxy _proxy; @EventHandler public void preInit(FMLPreInitializationEvent event) { if(FMLCommonHandler.instance().getEffectiveSide() == Side.CLIENT) _proxy = new ClientProxy(); else _proxy = new ServerProxy(); _proxy.preInit(event); } ... //Other handlers ... There ServerProxy.preInit() is: public void init(FMLInitializationEvent e) { System.out.println("init server!"); ServerRegisterer.init(e); PlayerData.load(); } But now I don't know what to do with registering things: as I understand, I don't have to register anything on logical server when it is physically a client. (Because init methods of ServerProxy aren't called at all on the logical server) So, what should I do? I would be happy if there is a way of programming my mod, with only logical server-client separation.
