[Solved] [1.16.5] Unknown biome id emitted by layers: 174

[Zemelua]

I implement a custom biome in a custom dimension and it crashes when I try to enter the custom dimension with /execute in umu_arcanum: the_silence run tp 0 0 0 (Unknown biome id emitted by layers: 174). I've referred to some mods that implement custom biomes in custom dimensions, but I'm not sure why this error is occurring.

Here is my code: https://github.com/Zemelua/UMU-Arcanum

[Luis_ST]

post full log please,
but i think your Biome is not registered with an ID,
because the vanilla Biome IDs end with 173 so 174 is a modded biome

Note: if you using the vanilla biome layer system it can lead problems if two mods are register a biome with the same id

When I registered in data/modid/worldgen/biome/biome.json, I thought that I didn't need to use DeferredRegister, but I got the same error when I didn't use DeferredRegister. No other mods have been introduced.

[Luis_ST]

no not register with DeferredRegister you need to add your Biome to BiomeRegistry.TO_NAME

[Zemelua]

What is BiomeRegistry.TO_NAME? There are no such methods or fields in the BiomeRegistry class ...

[Luis_ST]

did you using mcp or moj mappings?

[Zemelua]

I'm using Intellij IDEA's Minecraft Develoment Plugin, so I'm not sure which map I'm using. Probably mcp.

WorldGenRegistrys has a static field Map <ResourceLocation, Supplier<?>> REGISTRY_NAME_TO_DEFAULT, which is private access. It looks like there are no other methods to access.

[Luis_ST]

thats the wrong class and the wrong object type its:
net.minecraft.world.biome.BiomeRegistry.idToKeyMap or net.minecraft.world.biome.BiomeRegistry.TO_NAME which is a Int2ObjectMap

[Zemelua]

I found net.minecraft.world.biome.BiomeRegistry.idToKeyMap but it's private access. There are no other methods to access.

According to this , registration should be done just by putting the json file. I think I'm putting the json file in the right place, but what's wrong ...

[Luis_ST]

no the normal registration is via json or DeferredRegister
but you should register an id for your biome use Refection or an Access Transformers do this in FMLCommonSetupEvent

[Zemelua]

understood. Will this be available in a future forge version or 1.17 without reflection?

[Zemelua]

public UMUArcanum() {
		UMUArcanumBiomes.initialize();
		UMUArcanumDimensions.initialize();

		FMLJavaModLoadingContext.get().getModEventBus().addListener(this::onFMLCommonSetup);
	}

	public void onFMLCommonSetup(final FMLCommonSetupEvent event) {
		try {
			Field field = BiomeRegistry.class.getDeclaredField("idToKeyMap");
			Int2ObjectMap<RegistryKey<Biome>> map = (Int2ObjectMap<RegistryKey<Biome>>) field.get(null);
			map.put(174, UMUArcanumBiomes.DIM_FOREST);
		} catch (NoSuchFieldException exception) {
			exception.printStackTrace();
		} catch (IllegalAccessException e) {
			e.printStackTrace();
		}
	}

Well, I still get the error. What should i do?

[Luis_ST]

post the error log...

same.

[Luis_ST]

you get the same error beacuse you never call setAccessible for the Field

Edited August 14, 2021 by Luis_ST

[Zemelua]

public void onFMLCommonSetup(final FMLCommonSetupEvent event) {
		try {
			Field field = BiomeRegistry.class.getDeclaredField("idToKeyMap");
			field.setAccessible(true);
			Int2ObjectMap<RegistryKey<Biome>> map = (Int2ObjectMap<RegistryKey<Biome>>) field.get(null);
			map.put(174, UMUArcanumBiomes.DIM_FOREST);
		} catch (NoSuchFieldException exception) {
			exception.printStackTrace();
		} catch (IllegalAccessException e) {
			e.printStackTrace();
		}
	}

I still get the same error. What's wrong......

[Luis_ST]

you also need to set the field you only get the field from the class

[Zemelua]

public void onFMLCommonSetup(final FMLCommonSetupEvent event) {
		try {
			Field field = BiomeRegistry.class.getDeclaredField("idToKeyMap");
			Field modifiersField = Field.class.getDeclaredField("modifiers");
			modifiersField.setAccessible(true);
			modifiersField.setInt(field, field.getModifiers() & ~Modifier.PRIVATE & ~Modifier.FINAL);
			Int2ObjectMap<RegistryKey<Biome>> map = (Int2ObjectMap<RegistryKey<Biome>>) field.get(null);
			map.put(174, UMUArcanumBiomes.DIM_FOREST);
			field.set(null, map);
			LOGGER.warn(field.get(null).toString());
		} catch (NoSuchFieldException exception) {
			exception.printStackTrace();
		} catch (IllegalAccessException e) {
			e.printStackTrace();
		}
	}

Is it like this? I still get the error ...

Luis, what the F are you doing. This is not Minecraft 1.2.5 where you register things by ID.

The only issue here is that you never register your Biome, because you do not register the DeferredRegister to the event bus. Once that is fixed the code in the Git repo works just fine without any reflection or ID hacks.

did you know how the Biome Layer works, did you looked at the vanilla code, sounds like you don't knw much about the biome layer they still use the ids
which is why i hate this system, but forge dosen't has a BiomeProvider/BiomeSource which make this easly

and just use the IDs of your biome as obtained from ForgeRegistries.BIOMES

forge has biome IDs?

[Zemelua]

ahhh, I was really stupid. I've used Deferred Register many times before, but forgot to register it this time. Luis, diesieben, sorry for the hassle, and thank you. Registering the Deferred Register worked perfectly.
