(Solved)[1.15.2]How do I add custom biome?

[kyazuki]

I want to add a custom biome which is made by 1 block.

However I can't change stone layer.

How do I do it?

@SubscribeEvent
  public static void onRegisterBiome(RegistryEvent.Register<Biome> event) {
    TEST_BIOME.setRegistryName("test_biome");
    ForgeRegistries.BIOMES.register(TEST_BIOME);
    BiomeDictionary.addTypes(TEST_BIOME, BiomeDictionary.Type.PLAINS);
    BiomeManager.addSpawnBiome(TEST_BIOME);
  }

public class TestBiome extends Biome {
  public TestBiome() {
    super((new Builder()).surfaceBuilder(SurfaceBuilder.DEFAULT, new SurfaceBuilderConfig(TestMod.TEST_BLOCK.getDefaultState(), TestMod.TEST_BLOCK.getDefaultState(), TestMod.TEST_BLOCK.getDefaultState())).precipitation(RainType.RAIN).category(Category.PLAINS).depth(0.125F).scale(0.05F).temperature(0.8F).downfall(0.4F).waterColor(4159204).waterFogColor(329011).parent((String) null));
    
    DefaultBiomeFeatures.addCarvers(this);
    DefaultBiomeFeatures.addLakes(this);

    this.addSpawn(EntityClassification.CREATURE, new SpawnListEntry(EntityType.SHEEP, 12, 4, 4));
    this.addSpawn(EntityClassification.CREATURE, new SpawnListEntry(EntityType.PIG, 10, 4, 4));
    this.addSpawn(EntityClassification.CREATURE, new SpawnListEntry(EntityType.CHICKEN, 10, 4, 4));
    this.addSpawn(EntityClassification.CREATURE, new SpawnListEntry(EntityType.COW, 8, 4, 4));
    this.addSpawn(EntityClassification.CREATURE, new SpawnListEntry(EntityType.HORSE, 5, 2, 6));
    this.addSpawn(EntityClassification.CREATURE, new SpawnListEntry(EntityType.DONKEY, 1, 1, 3));
    this.addSpawn(EntityClassification.AMBIENT, new SpawnListEntry(EntityType.BAT, 10, 8, 8));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.SPIDER, 100, 4, 4));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.ZOMBIE, 95, 4, 4));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.ZOMBIE_VILLAGER, 5, 1, 1));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.SKELETON, 100, 4, 4));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.CREEPER, 100, 4, 4));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.SLIME, 100, 4, 4));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.ENDERMAN, 10, 1, 4));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.WITCH, 5, 1, 1));
  }
}

 

It's solved by using OverworldGenSettings#setDefaultBlock.

@kyazuki Can you show the new code? I am interessing by making Biomes and find anything on the Web for the 1.15.2. Then i want compare your method with the Vanilla method.

[kyazuki]

My mod add a new world type which generates only my biome.

My biome is made by 1 block and fluids.

 

WorldType:

public class TestWorldType extends WorldType {
  public TestWorldType() {
    super("testworld");
  }

  @Override
  public ChunkGenerator<?> createChunkGenerator(World world) {
    if (world.getDimension().getType() == DimensionType.OVERWORLD) {
      OverworldGenSettings overworldGenSettings = new OverworldGenSettings();
      SingleBiomeProviderSettings biomeProviderSettings = new SingleBiomeProviderSettings(world.getWorldInfo());
      biomeProviderSettings.setBiome(TestWorld.TEST_BIOME);
      overworldGenSettings.setDefaultBlock(TestWorld.TEST_BLOCK.getDefaultState());
      return new OverworldChunkGenerator(world, new SingleBiomeProvider(biomeProviderSettings), overworldGenSettings);
    } else
      return super.createChunkGenerator(world);
  }
}

 

 

Biome(I refered to PlainsBiome):

public class TestBiome extends Biome {
  private static final BlockState WATER = Blocks.WATER.getDefaultState();
  private static final BlockState LAVA = Blocks.LAVA.getDefaultState();
  public static final BlockState TEST_BLOCK_STATE = TestWorld.TEST_BLOCK.getDefaultState();
  public static final TreeFeatureConfig TEST_TREE_CONFIG = (new TreeFeatureConfig.Builder(new SimpleBlockStateProvider(TEST_BLOCK_STATE), new SimpleBlockStateProvider(TEST_BLOCK_STATE), new BlobFoliagePlacer(2, 0))).baseHeight(4).heightRandA(2).foliageHeight(3).ignoreVines().setSapling((IPlantable) TestWorld.TEST_BLOCK).build();
  public static final BlockStateProvidingFeatureConfig HAY_PILE_CONFIG = new BlockStateProvidingFeatureConfig(new SimpleBlockStateProvider(TestWorld.TEST_BLOCK.getDefaultState()));

  public TestBiome() {
    super((new Builder()).surfaceBuilder(SurfaceBuilder.DEFAULT, new SurfaceBuilderConfig(TEST_BLOCK_STATE, TEST_BLOCK_STATE, TEST_BLOCK_STATE)).precipitation(RainType.RAIN).category(Category.PLAINS).depth(0.125F).scale(0.05F).temperature(0.8F).downfall(0.4F).waterColor(4159204).waterFogColor(329011).parent((String) null));

    TestVillagePools.init();
    this.addStructure(Feature.VILLAGE.withConfiguration(new VillageConfig("village/test/town_centers", 6)));

    this.addCarver(GenerationStage.Carving.AIR, Biome.createCarver(new TestCaveWorldCarver(ProbabilityConfig::deserialize, 256), new ProbabilityConfig(0.14285715F)));
    this.addCarver(GenerationStage.Carving.AIR, Biome.createCarver(new TestCanyonWorldCarver(ProbabilityConfig::deserialize), new ProbabilityConfig(0.02F)));
    this.addFeature(GenerationStage.Decoration.LOCAL_MODIFICATIONS, new TestLakesFeature(BlockStateFeatureConfig::func_227271_a_).withConfiguration(new BlockStateFeatureConfig(WATER)).withPlacement(Placement.WATER_LAKE.func_227446_a_(new ChanceConfig(4))));
    this.addFeature(GenerationStage.Decoration.LOCAL_MODIFICATIONS, new TestLakesFeature(BlockStateFeatureConfig::func_227271_a_).withConfiguration(new BlockStateFeatureConfig(LAVA)).withPlacement(Placement.LAVA_LAKE.func_227446_a_(new ChanceConfig(80))));
    this.addFeature(GenerationStage.Decoration.VEGETAL_DECORATION, Feature.NORMAL_TREE.withConfiguration(TEST_TREE_CONFIG).withPlacement(Placement.COUNT_EXTRA_HEIGHTMAP.func_227446_a_(new AtSurfaceWithExtraConfig(0, 0.05F, 1))));
    this.addFeature(GenerationStage.Decoration.SURFACE_STRUCTURES, Feature.VILLAGE.withConfiguration(new VillageConfig("village/plains/town_centers", 6)).withPlacement(Placement.NOPE.func_227446_a_(IPlacementConfig.NO_PLACEMENT_CONFIG)));

    this.addSpawn(EntityClassification.CREATURE, new SpawnListEntry(EntityType.SHEEP, 12, 4, 4));
    this.addSpawn(EntityClassification.CREATURE, new SpawnListEntry(EntityType.PIG, 10, 4, 4));
    this.addSpawn(EntityClassification.CREATURE, new SpawnListEntry(EntityType.CHICKEN, 10, 4, 4));
    this.addSpawn(EntityClassification.CREATURE, new SpawnListEntry(EntityType.COW, 8, 4, 4));
    this.addSpawn(EntityClassification.CREATURE, new SpawnListEntry(EntityType.HORSE, 5, 2, 6));
    this.addSpawn(EntityClassification.CREATURE, new SpawnListEntry(EntityType.DONKEY, 1, 1, 3));
    this.addSpawn(EntityClassification.AMBIENT, new SpawnListEntry(EntityType.BAT, 10, 8, 8));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.SPIDER, 100, 4, 4));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.ZOMBIE, 95, 4, 4));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.ZOMBIE_VILLAGER, 5, 1, 1));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.SKELETON, 100, 4, 4));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.CREEPER, 100, 4, 4));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.SLIME, 100, 4, 4));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.ENDERMAN, 10, 1, 4));
    this.addSpawn(EntityClassification.MONSTER, new SpawnListEntry(EntityType.WITCH, 5, 1, 1));
  }
}

@kyazuki did you have to register anything related to your new world type? Or since you overrided the method did it just work from there? I am having trouble not only finding my biome but being able to create a world with just my biome.

 

I am able to see my biome using the buffet world when creating a world. I assume that means my biome is registered correctly but I haven't seen it in the overworld or been able to create just a world with the biome itself.

 

I would love to see your main class and where you registered your biome using the Forge DeferredRegister. Thanks!

 

[kyazuki]

My world type generates only 1 biome.

So I use SingleBiomeProvider.

return new OverworldChunkGenerator(world, new SingleBiomeProvider(biomeProviderSettings), overworldGenSettings);

@kyazuki Thanks for the help! Got it to work.
