Hi,

I am working on a mod which adds a custom biome to the overworld, the /locatebiome command lists my biome as well, but it shows that the type "tutorial:tutorial_biome"  cannot be found in "minecraft:overworld".

My Biome JSON file: https://pastebin.com/8QUJcSxJ

My Surface Builder JSON file: https://pastebin.com/hVJBEjSd

My Main.java File: https://pastebin.com/c288ptJ7

 

Also, please mention an alternative to extending the Biome class, as it's no longer possible. I am tired of JSONs.

Thanks in advance!

Can you please post a git repo it's easier to handle many classes, inside the Biome class there is a sub class Builder you should use it to create a Biome 

Here you go,

https://github.com/JustINCodingUK/Biome-Mod

use BiomeManager#addBiome

Like this?

public void commonSetup(FMLCommonSetupEvent e) {
		e.enqueueWork(() -> {
			BiomeEntry entry = new BiomeEntry(stony, 1);
			BiomeManager.addBiome(BiomeType.COOL, entry);
			BiomeManager.addAdditionalOverworldBiomes(stony);
		}
		);

you then no longer need BiomeManager#addAdditionalOverworldBiomes
you also need to call BiomeDictionary#addTypes

Overall, I have made these changes to my Main (and only) class.

package com.hastev.biomes;


import net.minecraft.util.RegistryKey;
...

@Mod("tutorial")

public class Main {
	public static final RegistryKey<Biome> stony = RegistryKey.create(Registry.BIOME_REGISTRY, new ResourceLocation("tutorial", "tutorial_biome"));
	
	public Main() {
		IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus();
	        bus.addListener(EventPriority.LOWEST, this::commonSetup);
	}

	public void commonSetup(FMLCommonSetupEvent e) {
		e.enqueueWork(() -> {
			BiomeManager.addBiome(BiomeType.COOL, new BiomeEntry(stony, 1));
			BiomeDictionary.addTypes(stony, Type.SANDY);
		}
		);
	}
	
}

And, Minecraft is now crashing with the errors:

1. java.lang.IllegalStateException: Unknown biome id emitted by layers: -1

You can add biomes without json. this is how i do it

    public static final DeferredRegister<Biome> Mod_biomes = DeferredRegister.create(ForgeRegistries.BIOMES, test.MOD_ID);

    public static final RegistryObject<Biome> test_forest = Mod_biomes.register("test_forest",()-> TestForestBiome.makeTestForestBiome(0.4f,0.6f));

    public static final RegistryKey<Biome> TEST_FOREST_KEY = RegistryKey.create(Registry.BIOME_REGISTRY, new ResourceLocation(test.MOD_ID, "test_forest"));

    public static void addBiomesToOverworld() {
        BiomeManager.addBiome(BiomeManager.BiomeType.WARM, new BiomeManager.BiomeEntry(TEST_FOREST_KEY, 1));
    }

Hi UserMC123,

Thanks for your reply, but I actually know how to do this stuff. I am confused with the Custom Biome Class (In yours, I think it's TestForestBiome). It would be great if you could post your Custom Biome class in a Git repo or some other site.

you need to use Biome.Builder look at the BiomeMaker for an example

this is the class for the biome:

 private static int getSkyColorWithTemperatureModifier(float p_244206_0_) {
        float lvt_1_1_ = p_244206_0_ / 3.0F;
        lvt_1_1_ = MathHelper.clamp(lvt_1_1_, -1.0F, 1.0F);
        return MathHelper.hsvToRgb(0.62222224F - lvt_1_1_ * 0.05F, 0.5F + lvt_1_1_ * 0.1F, 1.0F);
    }

    public static Biome makeTestForestBiome(float depth, float scale) {
        MobSpawnInfo.Builder spawnInf = new MobSpawnInfo.Builder();
        DefaultBiomeFeatures.farmAnimals(spawnInf);
        DefaultBiomeFeatures.commonSpawns(spawnInf);
        spawnInf.setPlayerCanSpawn();
        net.minecraft.world.biome.BiomeGenerationSettings.Builder builder = (new net.minecraft.world.biome.BiomeGenerationSettings.Builder()).surfaceBuilder(ConfiguredSurfaceBuilders.GRASS);
        DefaultBiomeFeatures.addDefaultCarvers(builder);
        DefaultBiomeFeatures.addDefaultLakes(builder);
        DefaultBiomeFeatures.baseJungleSpawns(spawnInf);
        DefaultBiomeFeatures.addDefaultMonsterRoom(builder);
        DefaultBiomeFeatures.addDefaultUndergroundVariety(builder);
        DefaultBiomeFeatures.addDefaultOres(builder);
        DefaultBiomeFeatures.addDefaultSoftDisks(builder);
        DefaultBiomeFeatures.addForestGrass(builder);
        DefaultBiomeFeatures.addForestGrass(builder);
        DefaultBiomeFeatures.addFerns(builder);
        DefaultBiomeFeatures.addJungleTrees(builder);
        DefaultBiomeFeatures.addDefaultMushrooms(builder);
        DefaultBiomeFeatures.addDefaultSprings(builder);
        DefaultBiomeFeatures.addJungleGrass(builder);
        DefaultBiomeFeatures.addLightBambooVegetation(builder);
        return (new net.minecraft.world.biome.Biome.Builder()).precipitation(Biome.RainType.RAIN).biomeCategory(Biome.Category.JUNGLE).depth(depth).scale(scale).temperature(0.6F).downfall(0.2F).specialEffects((new net.minecraft.world.biome.BiomeAmbience.Builder()).waterColor(3124991).waterFogColor(5541815).fogColor(14412287).foliageColorOverride(8640564).skyColor(getSkyColorWithTemperatureModifier(0.6F)).ambientMoodSound(MoodSoundAmbience.LEGACY_CAVE_SETTINGS).build()).mobSpawnSettings(spawnInf.build()).generationSettings(builder.build()).build();
    }

Thanks a lot @Luis_ST and @UserMC123. My Biome is now generating in the overworld and the problem is solved.
