[1.7.2] Make Biome Spawn at Specific Chunks

[TLHPoE]

I found out how to make the world generate only 1 specific biome, but how would I make the world generate a specific biome at a specific chunk coordinate? Overriding getBiomeGenAt does nothing, I think it's only for seeing what biome is at that chunk coordinate.

 

My Chunk Manager Class:

package ttm.world;

import java.util.Arrays;
import java.util.List;
import java.util.Random;

import net.minecraft.world.ChunkPosition;
import net.minecraft.world.biome.BiomeGenBase;
import net.minecraft.world.biome.WorldChunkManager;

public class WorldChunkManagerTtM extends WorldChunkManager {
@Override
public BiomeGenBase getBiomeGenAt(int x, int y) {
	return BiomeGenBase.desertHills;
}

@Override
public BiomeGenBase[] getBiomesForGeneration(BiomeGenBase[] biomes, int par2, int par3, int par4, int par5) {
	if(biomes == null || biomes.length < par4 * par5) {
		biomes = new BiomeGenBase[par4 * par5];
	}

	Arrays.fill(biomes, 0, par4 * par5, BiomeGenBase.desertHills);
	return biomes;
}

@Override
public float[] getRainfall(float[] rain, int par2, int par3, int par4, int par5) {
	if(rain == null || rain.length < par4 * par5) {
		rain = new float[par4 * par5];
	}

	Arrays.fill(rain, 0, par4 * par5, BiomeGenBase.desertHills.rainfall);
	return rain;
}

@Override
public BiomeGenBase[] loadBlockGeneratorData(BiomeGenBase[] biomes, int par2, int par3, int par4, int par5) {
	if(biomes == null || biomes.length < par4 * par5) {
		biomes = new BiomeGenBase[par4 * par5];
	}

	Arrays.fill(biomes, 0, par4 * par5, BiomeGenBase.desertHills);
	return biomes;
}

@Override
public ChunkPosition findBiomePosition(int x, int y, int p_150795_3_, List p_150795_4_, Random p_150795_5_) {
	return p_150795_4_.contains(BiomeGenBase.desertHills) ? new ChunkPosition(x - p_150795_3_ + p_150795_5_.nextInt(p_150795_3_ * 2 + 1), 0, y - p_150795_3_ + p_150795_5_.nextInt(p_150795_3_ * 2 + 1)) : null;
}

@Override
public boolean areBiomesViable(int par1, int par2, int par3, List par4List) {
	return par4List.contains(BiomeGenBase.desertHills);
}
}

Ok, I haven't found anything yet. Can someone at least point me to where Minecraft decides what biome to generate?

Hi

 

These look like promising places (never tried it)

GenLayerBiome (randomly chooses biomes from a list)

WorldChunkManager.getBiomesForGeneration

ChunkProviderGenerate.initializeNoiseField
