I added a biome to Minecraft, but I want to make a custom world generation for my biome.

Here is my code:

package com.kg.kgforge.c;

import com.kg.kgforge.KGForge;
import net.minecraft.util.RegistryKey;
import net.minecraft.util.ResourceLocation;
import net.minecraft.world.biome.Biome;
import net.minecraft.world.biome.BiomeAmbience;
import net.minecraft.world.biome.BiomeGenerationSettings;
import net.minecraft.world.biome.MobSpawnInfo;
import net.minecraftforge.common.BiomeDictionary;
import net.minecraftforge.common.BiomeManager;
import net.minecraftforge.registries.ForgeRegistries;

public class CBiomes {
    public static final Biome BLACK_BIOME = new Biome.Builder()
        .precipitation(Biome.RainType.NONE)
        .biomeCategory(Biome.Category.NONE)
        .depth(1)
        .scale(1)
        .temperature(20)
        .downfall(1)
        .specialEffects(new BiomeAmbience.Builder()
            .fogColor(0)
            .waterColor(0)
            .waterFogColor(0)
            .grassColorOverride(0)
            .skyColor(0)
            .build()
        )
        .generationSettings(BiomeGenerationSettings.EMPTY)
        .mobSpawnSettings(MobSpawnInfo.EMPTY)
        .build();
    public static void setupBiome(Biome biome, String id, BiomeManager.BiomeType biomeType, int weight, BiomeDictionary.Type... types) {
        CRegistries.BIOMES.register(id, () -> biome);
        RegistryKey<Biome> key = RegistryKey.create(
            ForgeRegistries.Keys.BIOMES,
            new ResourceLocation(KGForge.MODID, id)
        );
        BiomeDictionary.addTypes(key, types);
        BiomeManager.addBiome(biomeType, new BiomeManager.BiomeEntry(key, weight));
    }
}

(If more codes are needed, I can paste the codes in other files)

I think the problem is in the mob attributes.

what problem?
D7 told you what to do first...!
and you can create a custom BiomeGenerationSettings via BiomeGenerationSettings.Builder

Oh, I'm really sorry, I replied this in the wrong topic...
