[1.12.2] Odd Generation with Ores


Recommended Posts

Hello! I've been trying out Forge modding, and recently, I've managed to figure out how to render blocks, probably setup sided proxies (Without CommonProxy) and some other mostly irrelevant things

However, I've been stumped with generation. I mostly understand what's going on, however some code must keep slipping by me because all of my ores are generating in an odd diagonal pattern across multiple chunks.

What is it that I'm doing wrong, and how can I make sure not to do it again in the future?


My WorldGeneration Class:


package world;

import net.minecraft.block.state.IBlockState;
import net.minecraft.block.state.pattern.BlockMatcher;
import net.minecraft.init.Blocks;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.gen.IChunkGenerator;
import net.minecraft.world.gen.feature.WorldGenMinable;
import net.minecraftforge.fml.common.IWorldGenerator;

import java.util.Random;

import com.ghast.aquarius.blocks.ModBlocks;

public class WorldGeneration implements IWorldGenerator {
    public void generate(Random random, int chunkX, int chunkZ, World world, IChunkGenerator chunkGenerator, IChunkProvider chunkProvider) {
        if(world.provider.getDimension() == 0) {
            generateOverworld(random, chunkZ, chunkZ, world, chunkGenerator, chunkProvider);
    private void generateOverworld(Random random, int chunkX, int chunkZ, World world, IChunkGenerator chunkGenerator, IChunkProvider chunkProvider) {
        generateOre(ModBlocks.grainedstone.getDefaultState(), world, random, chunkX * 16, chunkZ * 16, 16, 64, 4 + random.nextInt(4), 6);
    private void generateOre(IBlockState ore, World world, Random random, int x, int z, int minY, int maxY, int size, int chances) {
        int deltaY = maxY - minY;
        for (int i = 0; i < chances; i++) {
            BlockPos pos = new BlockPos(x + random.nextInt(16), minY + random.nextInt(deltaY), z + random.nextInt(16));
            WorldGenMinable gen = new WorldGenMinable(ore, size);
            gen.generate(world, random, pos);

That's your problem.
