I've tried everything I can think of at the moment to register a configuration file for one of my mods in 1.15. I've looked at a bunch of source code from other mods to see what I am doing wrong, but I can't tell what's different.

 

I run this code during the FMLCommonSetupEvent:

ModLoadingContext.get().registerConfig(Type.COMMON, commonSpecPair.getRight());

which references this:

private static final Pair<Common, ForgeConfigSpec> commonSpecPair = new Builder().configure(Common::new);

and creates an instance of:

private static final class Common {
		private final DoubleValue heightWeight, metallicityWeight;
		private final BooleanValue realisticLightning, spawnFire;

		public Common(Builder builder) {
			builder.comment("Common settings").push("General");

			heightWeight = builder.comment("TODO").defineInRange("Height Weight", .5, 0, 1);
			metallicityWeight = builder.comment("TODO").defineInRange("Metallicity Weight", .5, 0, 1);
			realisticLightning = builder.comment("TODO").define("Realistic Lightning", true);
			spawnFire = builder.comment("TODO").define("Spawn Fire", true);

			builder.pop();
		}
	}

 

However, the configuration file is never created and no log messages are given that could give me a hint as to what is going wrong.

 

Update: I've only found one workaround that makes it generate correctly. I don't think it's the proper way to do this, so I'm hoping for a better method. I just have to run this after registering the config.

ConfigTracker.INSTANCE.loadConfigs(Type.COMMON, FMLPaths.CONFIGDIR.get());

Put your registerConfig call in your mod constructor.

Mod event order:

• Mod construction (move yourregisterConfig here)
• RegistryEvent.Register<T>
• Config loading
• Common setup (your registerConfig was in here)
• Sided setup
• ...

See ModLoader.loadMods, line 152 for source.

Alright, that works. I was registering it in a static FMLCommonSetupEvent method that was registered with @EventBusSubscriber and @SubscribeEvent.
