Is it possible to have a separate Config.class and put all my configs in a separate method in there, and just call the class in my Pre-Init event with something like this:

 

Config config = new Config();
config.configure();

Yes. You would add something like this to the preInit:

 

    @EventHandler
    public void preInit(FMLPreInitializationEvent event) {
    	RoadsConfig config = new RoadsConfig();
    	RoadsConfig.loadConfig(event); 

 

If you wanna see it in action, go to my github.

Thanks
