I have been following TurtyWurty's tutorial on how to add Ore Generation to a mod, and I have followed it fully as much as I am aware. I have created a new world, and I cannot find it anywhere. It does load properly as an item, so that isn't the problem. Here is my code

 

RegistryHandler.java

package com.booktail.newdawn.util;

import com.booktail.newdawn.NewDawn;
import com.booktail.newdawn.blocks.BlockItemBase;
import com.booktail.newdawn.blocks.PrismallonBlock;
import com.booktail.newdawn.blocks.PrismallonOreBlock;
import com.booktail.newdawn.items.ItemBase;
import net.minecraft.block.Block;
import net.minecraft.item.Item;
import net.minecraftforge.fml.RegistryObject;
import net.minecraftforge.fml.javafmlmod.FMLJavaModLoadingContext;
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.ForgeRegistries;

public class RegistryHandler {

    public static final DeferredRegister<Item> ITEMS = new DeferredRegister<>(ForgeRegistries.ITEMS, NewDawn.MOD_ID);
    public static final DeferredRegister<Block> BLOCKS = new DeferredRegister<Block>(ForgeRegistries.BLOCKS, NewDawn.MOD_ID);

    public static void init() {
        ITEMS.register(FMLJavaModLoadingContext.get().getModEventBus());
        BLOCKS.register(FMLJavaModLoadingContext.get().getModEventBus());
    }

    //Item Declaration for "Hello World"
    public static final RegistryObject<Item> DINGUS = ITEMS.register("dingus", ItemBase::new);

    //Items
    public static final RegistryObject<Item> PRISMALLON_INGOT = ITEMS.register("prismallon_ingot", ItemBase::new);

    //Blocks (and Block Items)
    public static final RegistryObject<Block> PRISMALLON_BLOCK = BLOCKS.register("prismallon_block", PrismallonBlock::new);
    public static final RegistryObject<Item> PRISMALLON_BLOCK_ITEM = ITEMS.register("prismallon_block", ()-> new BlockItemBase(PRISMALLON_BLOCK.get()));

    public static final RegistryObject<Block> PRISMALLON_ORE_BLOCK = BLOCKS.register("prismallon_ore_block", PrismallonOreBlock::new);
    public static final RegistryObject<Item> PRISMALLON_ORE_BLOCK_ITEM = ITEMS.register("prismallon_ore_block", ()-> new BlockItemBase(PRISMALLON_ORE_BLOCK.get()));

}

 

NewDawnOreGen.java

package com.booktail.newdawn.world.gen;

import com.booktail.newdawn.util.RegistryHandler;
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.registries.ForgeRegistries;

public class NewDawnOreGen {

    public static void generateOre() {
        for(Biome biome : ForgeRegistries.BIOMES){
            ConfiguredPlacement customConfig = Placement.COUNT_RANGE.configure(new CountRangeConfig(20,5,5,25));
            biome.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Feature.ORE
                    .withConfiguration(new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, RegistryHandler.PRISMALLON_ORE_BLOCK.get().getDefaultState(), 10))
                    .withPlacement(customConfig));
        }
    }

}

I would greatly appreciate any help. I don't know why ore generation isn't happening in new worlds

The thing with Oregen is that if you're just unlucky you may not find it.

 

Try using an Xray mod.

If the value is set properly, it should be generating more frequently than coal

Is the loadComplete method running? I would double check via a log msg or breakpoint, just to be sure.

 

Also, I've always seen oregen go in FMLCommonSetupEvent, not FMLLoadCompleteEvent. Probably doesn't matter, I would guess it's a nuance of the tutorial you're following.

I think your main class NewDawn has to annotated with @EventBusSubscriber(modid = [your_modid], bus = Bus.MOD), but leave "@Mod"

Then the methods with @SubribeEvent (like your ore gen) will be executed

I used 

@Mod.EventBusSubscriber(bus = Mod.EventBusSubscriber.Bus.MOD)

And that made it work, thank you!
