Tutorial Creating empty (void) worlds in 1.13+

So I was looking for a way to generate void worlds in version 1.13 and above, I found some threads about the subject but they were mostly unclear, eventually I found a way (it was mentioned in one of the threads but was not really well explained) and I thought I should share it, hope it helps!

Step 1:
Creating a new chunk generator class that will extend the default ChunkGenerator class and will override the method that returns the chunk data.

Code:

import java.util.Random;

import javax.annotation.Nonnull;

import org.bukkit.World;
import org.bukkit.generator.ChunkGenerator;

public class EmptyChunkGenerator extends ChunkGenerator {

    @Override
    @Nonnull
    public ChunkData generateChunkData(@Nonnull World world, @Nonnull Random random, int x, int z, @Nonnull BiomeGrid biome) {
        return createChunkData(world);
    }
}

Step 2:
Generating a world using the chunk generator that we created in step 1.

Code:

WorldCreator wc = new WorldCreator("WORLD NAME HERE");
        wc.generator(new EmptyChunkGenerator()); //The chunk generator from step 1
        wc.createWorld();

Hope this helped you
