I have followed a tutorial and got my ores to generate in the regular Minecraft world, but I can't get it to generate in the Nether or the end. I already tried setting the values to get huge veins, and again, there are huge veins in the overworld but not a single ore in the Nether or the End. I have registered all the ores, and they are accessible through the Creative menu.

 

Here is my custom generation class that implements IWorldGenerator:

 

package eclipse.MoreApples.worldgen;

import java.util.Random;

import net.minecraft.world.World;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.gen.feature.WorldGenMinable;
import cpw.mods.fml.common.IWorldGenerator;
import eclipse.MoreApples.common.MoreApples;

public class AppleIronIngotWorldGeneration implements IWorldGenerator {

@Override
public void generate(Random random, int chunkX, int chunkZ, World world, IChunkProvider chunkGenerator, IChunkProvider chunkProvider) {

	switch(world.provider.dimensionId){
	case -1:
		generateNether(world, random, chunkX * 16, chunkZ * 16);
		break;
	case 0:
		generateSurface(world, random, chunkX * 16, chunkZ * 16);
		break;
	case 1:
		generateEnd(world, random, chunkX * 16, chunkZ * 16);
		break;
	}

}

private void generateSurface(World world, Random random, int i, int j) {

	for(int k = 0; k < 10; k++){
		int chunkX = i + random.nextInt(16);
		int chunkY = random.nextInt(256);
		int chunkZ = j + random.nextInt(16);

		(new WorldGenMinable(MoreApples.appleIron_ore.blockID, 64)).generate(world, random, chunkX, chunkY, chunkZ);
	}
	int randomGemGeneration = (int) (Math.random() * 4 +1);

	for(int k = 0; k <randomGemGeneration ; k++){
		int chunkX = i + random.nextInt(16);
		int chunkY = random.nextInt(256);
		int chunkZ = j + random.nextInt(16);

		(new WorldGenMinable(MoreApples.appleGem_ore.blockID, 64)).generate(world, random, chunkX, chunkY, chunkZ);
	}

}

private void generateEnd(World world, Random random, int i, int j) {
	for(int k = 0; k < 10; k++){
		int chunkX = i + random.nextInt(16);
		int chunkY = random.nextInt(256);
		int chunkZ = j + random.nextInt(16);

		(new WorldGenMinable(MoreApples.appleEnder_ore.blockID, 64)).generate(world, random, chunkX, chunkY, chunkZ);
	}

}


private void generateNether(World world, Random random, int i, int j) {

	for(int k = 0; k < 15; k++){
		int chunkX = i + random.nextInt(16);
		int chunkY = random.nextInt(256);
		int chunkZ = j + random.nextInt(16);

		(new WorldGenMinable(MoreApples.appleFlame_ore.blockID, 64)).generate(world, random, chunkX, chunkY, chunkZ);
	}

}

}

 

 

 

Does anyone know what I did wrong?

 

Thanks for reading! =)

 

That's because you are using WorldGenMinable without specifying what type of block to replace. There is a three-parameter version of the constructor, the 3rd parameter of which is the block to replace; without that, it defaults to the stone block, of which there is none in the Nether. No blocks to replace = no custom blocks.

Right! I completely forgot about that. Thanks a bunch, that solved it.
