[SOLVED] How to get a block from a blockposition


Recommended Posts

Hello there,

So while I was trying to make my mod I encountered a simple yet pretty difficult problem. How do you get a block (server side perhaps?) from a blockPosition? The particular problem i'm having is getting a World class which then allows you to get a block. Here are the pieces of code I need to use this for:

package net.hasanchik.neutroneum.util;

import net.minecraft.core.BlockPos;
import net.minecraft.world.level.block.Block;
import org.jetbrains.annotations.NotNull;
import net.minecraft.world.level.;

public class BasicUtils {
    public static class BlockUtils {
        public static BlockPos divideBlockPos(@NotNull BlockPos position, int divisor) {
            return new BlockPos(position.getX()/divisor, position.getY()/divisor, position.getZ()/divisor);
        public static Block[] getAllBlocksInRectangle(BlockPos position, BlockPos size, @NotNull Boolean centered) {
            BlockPos startingPosition = position;
            if (centered) {
                startingPosition.subtract(divideBlockPos(size, 2));
            for (int x = position.getX(); x <= size.getX(); x++) {
                for (int y = position.getY(); y <= size.getY(); y++) {
                    for (int z = position.getZ(); z <= size.getZ(); z++) {
                        World.world.getBlockState(new BlockPos(x, y, z)).getBlock();
        public static Block getAllBlocksInBox() {

package net.hasanchik.neutroneum.item.custom;

import net.hasanchik.neutroneum.util.BasicUtils;
import net.minecraft.core.BlockPos;
import net.minecraft.network.chat.Component;
import net.minecraft.util.RandomSource;
import net.minecraft.world.InteractionHand;
import net.minecraft.world.InteractionResultHolder;
import net.minecraft.world.entity.player.Player;
import net.minecraft.world.item.Item;
import net.minecraft.world.item.ItemStack;
import net.minecraft.world.level.Level;
import net.minecraft.world.level.block.Block;

import java.util.HashMap;

public class MetalDetectorItem extends Item {
    //TODO: find better way of storing detectable blocks
    public static final int animationFrames = 31;
    protected static HashMap<String, String> detectableBlocks = new HashMap<>();
    protected Integer closestOreDistance = 0;
    protected int

    public MetalDetectorItem(Properties properties) {

    private void print(String message, Player player) {
    public InteractionResultHolder<ItemStack> use(Level level, Player player, InteractionHand hand) {
        if(!level.isClientSide() && hand == InteractionHand.MAIN_HAND) {
            BlockPos playerBlockPos = BlockPos.containing(player.getPosition(1));
            BlockPos[] blocks = BasicUtils.BlockUtils.getAllBlocksInRectangle();

            this.closestOreDistance = RandomSource.createNewThreadLocalInstance().nextInt(animationFrames);
            print("test " + this.getClosestOreDistance(), player);

        return  super.use(level, player, hand);

    public int getClosestOreDistance() {
        return this.closestOreDistance;

Please keep in mind that the code isn't finished yet

You should also first check Level.isLoaded(BlockPos) to avoid unnecessary loading of chunks  - or crashing if you try to do that on that client.


If you don't have access to a Level, (either directly or from a player/entity) then you are probably doing something wrong.

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.

    • I have a structure, and sometimes several mobs spawn there. This is a boss and must spawn alone. Here is the code for spawning entities in the structure { "type": "minecraft:jigsaw", "start_pool": "egyptcraft:boss_pyramid/start_pool", "size": 5, "max_distance_from_center": 80, "biomes": "#egyptcraft:has_structure/boss_pyramid", "step": "surface_structures", "start_height": { "absolute": 0 }, "project_start_to_heightmap": "WORLD_SURFACE_WG", "use_expansion_hack": false, "spawn_overrides": { "monster": { "bounding_box": "full", "spawns": [ { "type": "egyptcraft:anubis", "maxCount": 1, "minCount": 1, "weight": 100 } ] } } } Maybe it's something else?
    • I have OreGenEvent.GenerateMinable event, I need to get a chance to spawn (generate) every ore that is processed in this event. Also e.getType().name().toString() is name this is the same block name by which it can be entered in the Block.getByID?  forge 1.12.2 59(recommended)
    • Hello everybody! Out of nowhere my minecraft doesn't allow me to play on forge 1.19.2 I tried to reinstall minecraft, doesn't have any mod right now on the forge version. Tried the newest version of forge, tried recommended version as well. I have the newest version of Java as well...   I dont know why it stopped working but it just stopped completly out of nowhere...   Thank you so much for your help guys ❤️
    • Hello, my world is crashing at 0% loaded and I don't know why. (Forge 43.2.14, 1.19.2) I have two worlds that I play on, and one works and the other doesn't, even with the same mod list. Here's the crash report: https://pastebin.com/AUbRwkGj
    • Minecraft 1.12.2 Very frustrating error. only ever occurs on one device. Started yesterday without prompting (maybe java updated or something?) Says things that have been imported actually arent when running client Reinstalled Intellij, cleared cache, cleaned and rebuilt gradle, redownloaded the entire file from git. Nothing works. (I believe I have the right plugins installed, dependencies OK, and am using corretto 1.8).   One thing I did for more of the below errors was just to explicitly import them, which was working up until this little guy who literally does not exist in forge to import. the class inhereting something inhereting it refers to import net.minecraftforge.registries.IForgeRegistryEntry.Impl, not net.minecraftforge.registries.IForgeRegistryEntry$Impl as the output implies. also I didn't even have to manually import these things for it to work on my other device. (which is just importing the minecraft package that contains them), but here I did have to just to get rid of a few errors--not even make anything work?? I dont know. (edited) here's the aforementioned "below error" (one of many like it): error: cannot access net.minecraftforge.registries.IForgeRegistryEntry.Impl public class BlockBase extends Block {        ^   class file for net.minecraftforge.registries.IForgeRegistryEntry$Impl not found Here's the class BlockBase:   package com.quantum.exodus.common.blocks; import com.quantum.exodus.ExodusMod; import net.minecraft.block.Block; import net.minecraft.block.material.Material; import net.minecraft.creativetab.CreativeTabs; import net.minecraft.item.Item; import net.minecraft.item.ItemBlock; import net.minecraftforge.registries.IForgeRegistryEntry.Impl; public class BlockBase extends Block { protected String name; public BlockBase(Material material, String name) { super(material); this.name = name; setTranslationKey(name); setRegistryName(name); } public void registerItemModel(Item itemBlock) { ExodusMod.proxy.registerItemRenderer(itemBlock, 0, name); } public Item createItemBlock() { return new ItemBlock(this).setRegistryName(getRegistryName()); } @Override public BlockBase setCreativeTab(CreativeTabs tab) { super.setCreativeTab(tab); return this; } }
