Hi all!

In my mod I load some parameters from config file.

All works fine and I tested synchronizations from server to client.

In my Mod class constructor i call:

//register the ForgeConfigSpec

ModLoadingContext.get().registerConfig(ModConfig.Type.SERVER, BookshelfConfig.server_config);

//here is where we load parameters

BookshelfConfig.loadConfig(BookshelfConfig.server_config, FMLPaths.CONFIGDIR.get().resolve(MODID + "-server.toml").toString());

 

Then in the ModConfigEvent handler i build some data structures...

@SubscribeEvent

public static void onModConfigEvent(ModConfigEvent event) {

    LOGGER.info("HELLO FROM ModConfigEvent " + event + " " + event.getPhase());

    //prepare tables

   BookshelfConfig.setupItems();

}

 

Is this the correct way to load config? Where should registration and data loading be done?

All you need to do is register the config. The Load and Reloading events should be handled to setup any caching that might occur. Any server related config information that requires an instance of MinecraftServer can be handled initially within FMLServerAboutToStartEvent and then updated with some sort of invalidator. However, this information should be cleared whenever the server is stopping as it will not persist across worlds.
