[1.16.3] Generate a vegetal decoration


Recommended Posts


I'm trying to generate a bush object in 1.16.3 and I need some help with it.

This is my attempt:


public static void initBushes() {
        Registry.register(WorldGenRegistries.field_243653_e, BlockInit.XP_BUSH.get().getRegistryName(),
                                .configure(new TopSolidRangeConfig(5, 5, 128))
    public static void setupBushes() {
        for (Map.Entry<RegistryKey<Biome>, Biome> biome : WorldGenRegistries.field_243657_i.func_239659_c_()) {
            if (!biome.getValue().getCategory().equals(Biome.Category.NETHER) && !biome.getValue().getCategory().equals(Biome.Category.THEEND)) {
                addFeatureToBiome(biome.getValue(), GenerationStage.Decoration.VEGETAL_DECORATION,

private static void addFeatureToBiome(Biome biome, GenerationStage.Decoration vegetalDecoration, ConfiguredFeature<?, ?> configuredFeature) {
        List<List<Supplier<ConfiguredFeature<?, ?>>>> biomeFeatures = new ArrayList<>(biome.func_242440_e().func_242498_c());
        while (biomeFeatures.size() <= vegetalDecoration.ordinal()) {
        List<Supplier<ConfiguredFeature<?, ?>>> features = new ArrayList<>(biomeFeatures.get(vegetalDecoration.ordinal()));
        features.add(() -> configuredFeature);
        biomeFeatures.set(vegetalDecoration.ordinal(), features);

        ObfuscationReflectionHelper.setPrivateValue(BiomeGenerationSettings.class, biome.func_242440_e(), biomeFeatures,"field_242484_f");


I can't get it to work.


If you need more code here is my github: https://github.com/Timebreaker900/MetalBushesMod/tree/1.16.3


Thanks in advance!!!

First, Problematic Code 11.

Second, no need to register the configured feature.

Third, you need to defer execution of the configs

Fourth, one try will fail about 99.9% of the time.

Fifth, you don't need to register the configured feature.

Sixth, try to avoid using someone else's source as a direct reference as it most likely has problems of its own. Instead, indirectly view the code and try to understand what it's attempting to do and apply the underlying logic in the correct method.
