so can someone help me make the ore that spawns in sand spawn higher? like on surface sand in deserts and stuff? not just lower down?

i need to do this without raising the other two ores up and the y coord specifications are written before the ores are set.

 

package ashtonsmod.common;

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;

public class WorldGen implements IWorldGenerator{
    
private static final int BlockX = 0;
private int BlockZ;

@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);
            case 0:
                generateSurface(world, random, chunkX * 16, chunkZ * 16);
            case -1:
                generateEnd(world, random, chunkX * 16, chunkZ * 16);
  }
  
}
    
private void generateNether(World world, Random random, int chunkX, int chunkZ) {
}

private void generateEnd(World world, Random random, int chunkX, int chunkZ){
}
    
private void generateSurface(World world, Random random, int chunkX,int chunkZ){
   int xCoord = chunkX;
   int yCoord = random.nextInt(64);
   int zCoord = chunkZ;
   (new WorldGenMinable(ashtonsmod.LightSteelOre.blockID, 7)).generate(world, random, (xCoord + random.nextInt(60)), yCoord, (zCoord + random.nextInt(60)));
   (new WorldGenMinable(ashtonsmod.AmethystOre.blockID, 5)).generate(world, random, (xCoord  + random.nextInt(60)), yCoord, (zCoord + random.nextInt(80)));
   (new WorldGenMinableSand(ashtonsmod.AmethystOre.blockID, 15)).generate(world, random, (xCoord  + random.nextInt(40)), yCoord, (zCoord + random.nextInt(40)));
  } 
}
   

..... Do it as you did at zCoord or xCoord ....
