ResourceManagerHelper registerReloadListener problem

[Slarper]

I use fabric api ResourceManagerHelper::registerReloadListener to register a reload listener, but the listener ONLY works when I reload the resource(like F3 + T ) and it doesn't work when the game initialization. This is my code: ( I use the listener to fetch a custom models.json file and some extra models.)

package net.fabricmc.example;

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import net.fabricmc.api.ModInitializer;
import net.fabricmc.example.event.listener.MagicaListeners;
import net.fabricmc.example.item.MagicaItems;
import net.fabricmc.example.util.ModelsJson;
import net.fabricmc.fabric.api.client.model.ModelLoadingRegistry;
import net.fabricmc.fabric.api.resource.ResourceManagerHelper;
import net.fabricmc.fabric.api.resource.SimpleSynchronousResourceReloadListener;
import net.minecraft.resource.Resource;
import net.minecraft.resource.ResourceManager;
import net.minecraft.resource.ResourceType;
import net.minecraft.util.Identifier;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.io.IOException;
import java.io.InputStreamReader;
import java.io.Reader;
import java.nio.charset.StandardCharsets;
import java.util.List;

public class Magica implements ModInitializer {
	// This logger is used to write text to the console and the log file.
	// It is considered best practice to use your mod id as the logger's name.
	// That way, it's clear which mod wrote info, warnings, and errors.
	public static final Logger LOGGER = LoggerFactory.getLogger("modid");
	public static final String MODID = "modid";

	public final static Gson GSON = new GsonBuilder().setPrettyPrinting().create();
	public static final String EXTRA_MODEL_SETTINGS_PATH = "extra/models.json";

	@Override
	public void onInitialize() {
		// This code runs as soon as Minecraft is in a mod-load-ready state.
		// However, some things (like resources) may still be uninitialized.
		// Proceed with mild caution.

		LOGGER.info("Hello Fabric world!");
        MagicaItems.load();
        MagicaListeners.load();


		ResourceManagerHelper.get(ResourceType.CLIENT_RESOURCES).registerReloadListener(
				new SimpleSynchronousResourceReloadListener() {
					@Override
					public Identifier getFabricId() {
						return new Identifier("modid","load_extra_models");
					}

					@Override
					public void reload(ResourceManager manager) {
						for (String namespace : manager.getAllNamespaces()){
							List<Resource> resources = null;
							try {
								resources = manager.getAllResources(new Identifier(namespace,EXTRA_MODEL_SETTINGS_PATH));
							} catch (IOException e) {
								// don't need to throw, it's normal.
							}
							if (resources == null){
								continue;
							}

							for (Resource resource : resources){
								Reader reader = new InputStreamReader(resource.getInputStream(), StandardCharsets.UTF_8);
								ModelsJson modelsJson = GSON.fromJson(reader, ModelsJson.class);
								for ( String model : modelsJson.models){
									ModelLoadingRegistry.INSTANCE.registerModelProvider(
											((manager1, out) -> {
												out.accept(new Identifier(model));
												Magica.LOGGER.info("load extra model : " + model);
											})
									);
								}
							}
						}


					}
				}
		);
	}
}

Oh no, I found the reason: ResourceReloadListener DOES work on the game's initialization stage. But it is always later than an ExtraModelProvider. So I can't load a config json file before I load extra models :(

You can load the config file from the ResourceManager passed to provideExtraModels.

Yes, I find it just now! I was so stupid!😂 I will update this discussion.

I AM A FOOL!
This is an existing ResourceManager in ExtraModelProvider's parameters so why I wanted to use a ResourceReloadListener to get my config file!

I want to kill myself now😂
