Custom Features
Sun, 08/30/2020 - 21:12

So I've Been working on custom features and i thought that it would be nice for me to share. So I will give the feature code for mushrooms in custom biomes. this go inside the custom biome java.

//import your custom blocks before running. and these

import net.minecraft.util.math.MutableBoundingBox;
import net.minecraft.util.math.BlockPos;
import net.minecraft.util.Direction;
import net.minecraft.tags.BlockTags;
import net.minecraft.block.HugeMushroomBlock;

import net.minecraft.block.Blocks;
import net.minecraft.block.BlockState;
import net.minecraft.block.Block;
import net.minecraft.world.gen.placement.Placement;
import net.minecraft.world.gen.feature.AbstractBigMushroomFeature;
import net.minecraft.world.gen.blockstateprovider.SimpleBlockStateProvider;
import net.minecraft.world.gen.IWorldGenerationReader;

import net.minecraft.world.gen.placement.FrequencyConfig;
import net.minecraft.world.gen.feature.BigMushroomFeatureConfig;
import com.mojang.datafixers.Dynamic;
import java.util.Random;
import java.util.function.Function;
import net.minecraft.block.HugeMushroomBlock;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.IWorld;

// this is the blockstate variables for HugeMushroomBlock modeled blocks, paste under static class CustomBiome and before public CustomBiome()

private static final BlockState MUSHROOM_BLOCK = MirasmiusMushroomBlockBlock.block.getDefaultState().with(HugeMushroomBlock.DOWN, Boolean.valueOf(false));
private static final BlockState MUSHROOM_STEM = Blocks.MUSHROOM_STEM.getDefaultState().with(HugeMushroomBlock.UP, Boolean.valueOf(false)).with(HugeMushroomBlock.DOWN, Boolean.valueOf(false));

// how to make the feature spawn, paste this under the Default Biome Features

addFeature(GenerationStage.Decoration.VEGETAL_DECORATION,  new MirasmiusMushroomFeature(BigMushroomFeatureConfig::deserialize)
					.withConfiguration(new BigMushroomFeatureConfig(new SimpleBlockStateProvider(MUSHROOM_BLOCK), new SimpleBlockStateProvider(MUSHROOM_STEM), 2))
					.withPlacement(Placement.COUNT_HEIGHTMAP.configure(new FrequencyConfig(1))));

//this is the custom feature for the big red mushroom shape, replace UtoreMushroomGrassBlock with the grass for your biome and UtoreDirtBlock with the custom dirt from your biome

static class MirasmiusMushroomFeature extends AbstractBigMushroomFeature{
		public MirasmiusMushroomFeature(Function<Dynamic<?>, ? extends BigMushroomFeatureConfig> config) {
