Hey,
How would I register my banner patterns? I'm totally confused because there's nothing dedicated to BannerPattern in ForgeRegistries class.
Thank you

I know very little about banner patterns but wouldn't this just be something like?

@Mod("examplemod")
public class ExampleMod
{
    private static final DeferredRegister<BannerPattern> BANNERS = DeferredRegister.create(Registry.BANNER_PATTERN_REGISTRY, "examplemod");
    public ExampleMod()
    {
        IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus();
        bus.addListener(this::setup);
        BANNERS.register(bus);
    }

    private void setup(final FMLCommonSetupEvent event)
    {
        BANNERS.register("mybanner", () -> new BannerPattern("myb"));
    }
}

Registry is the vanilla registry, its not deprecated, there is no special forge version.
