[1.16.1] Custom OreFillerType


Recommended Posts

I tried creating my own FillerBlockType and my custom ore won't generate. My plan was to have my custom ore (hematite) surrounded by iron ore. Can anyone help me? Here's my code below for the ore generation:


package com.theunknown.andraxxus.world.gen;

import com.theunknown.andraxxus.AndraxxMod;
import com.theunknown.andraxxus.util.RegistryHandler;
import net.minecraft.block.BlockState;
import net.minecraft.block.Blocks;
import net.minecraft.block.pattern.BlockMatcher;
import net.minecraft.world.biome.Biome;
import net.minecraft.world.gen.GenerationStage;
import net.minecraft.world.gen.feature.Feature;
import net.minecraft.world.gen.feature.OreFeatureConfig;
import net.minecraft.world.gen.placement.ConfiguredPlacement;
import net.minecraft.world.gen.placement.CountRangeConfig;
import net.minecraft.world.gen.placement.Placement;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.event.lifecycle.FMLLoadCompleteEvent;
import net.minecraftforge.registries.ForgeRegistries;

@Mod.EventBusSubscriber(modid = AndraxxMod.MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD)
public class AndraxxOreGen {

    public static  OreFeatureConfig.FillerBlockType END_STONE = OreFeatureConfig.FillerBlockType.create("END_STONE", "end_stone", new BlockMatcher(Blocks.END_STONE));
    public static  OreFeatureConfig.FillerBlockType IRON_ORE = OreFeatureConfig.FillerBlockType.create("IRON_ORE", "iron_ore", new BlockMatcher(Blocks.IRON_ORE));

    public static void generateOres(FMLLoadCompleteEvent event) {
        for (Biome biome : ForgeRegistries.BIOMES)   {

            if (biome.getCategory() == Biome.Category.NETHER) {
                genOre(biome, 14, 22, 4, 111, OreFeatureConfig.FillerBlockType.NETHERRACK, RegistryHandler.HEMATITE_BLOCK.get().getDefaultState(), 0);
            } else if (biome.getCategory() == Biome.Category.THEEND) {
                genOre(biome, 14, 22, 4, 111, END_STONE, RegistryHandler.HEMATITE_BLOCK.get().getDefaultState(), 0);
            } else {
                genOre(biome, 14, 22, 4, 111, OreFeatureConfig.FillerBlockType.create("IRON_ORE", "iron_ore", new BlockMatcher(Blocks.IRON_ORE)), RegistryHandler.HEMATITE_BLOCK.get().getDefaultState(), 14);


    private static void genOre (Biome biome, int count, int bottomOffset, int topOffset, int max, OreFeatureConfig.FillerBlockType filler, BlockState defaultBlockstate, int size)  {
        CountRangeConfig range = new CountRangeConfig(count, bottomOffset, topOffset, max);
        OreFeatureConfig feature = new OreFeatureConfig(filler, defaultBlockstate, size);
        ConfiguredPlacement config = Placement.COUNT_RANGE.configure(range);
        biome.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Feature.ORE.withConfiguration(feature).withPlacement(config));

I created a new thread for you. In the future please don't post in old topics.


Step one is: When using IExtensibleEnum you must ensure that the things you create have a unique name. So include your ModID!.

Due to how ore generation works, this won't work. You can only replace blocks that are generated previous to ores.

If you want your ore surrounded by iron, generate the iron yourself.

My bad, I'm totally sorry, I just sorta barged in here desperate for a solution. Also thanks for the help, I will try this!

Also, where is my mod ID going, and do I have to repeat the ore generation cod for iron ore, and then the hematite ore? How do I generate the iron ore? 


I know I sound dumb; I'm super new to modding and just started learning last week and I don't know any Java other than what I've learned so far (which isn't a lot)


Also this is 1.16.1 btw
