Hi, i'm trying to generate ores in my world but the code seems not working

The first thing i've done is a world generator class

 

public class WorldGenMinableMW implements IWorldGenerator {

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

	switch(world.provider.getDimensionId()) {
		case 0:
			generateOverworld(random, world, chunkX*16, chunkZ*16);
			break;
		default:
			generateOverworld(random, world, chunkX*16, chunkZ*16);
	}

}

private void generateOverworld(Random random, World world, int x, int z) {
	addOres(MWBlocks.ruby_ore, world, random, x, z, 4, 5, 0, 16);
	addOres(MWBlocks.sapphire_ore, world, random, x, z, 4, 5, 0, 16);
	addOres(MWBlocks.copper_ore, world, random, x, z, 6, 10, 0, 30);
	addOres(MWBlocks.bronze_ore, world, random, x, z, 6, 10, 0, 30);
	addOres(MWBlocks.silver_ore, world, random, x, z, 6, 10, 0, 20);
	addOres(MWBlocks.aluminium_ore, world, random, x, z, 6, 10, 0, 20);
	addOres(MWBlocks.pyrite_ore, world, random, x, z, 8, 20, 0, 50);
	addOres(MWMetadataBlocks.marble.getStateFromMeta(0).getBlock(), world, random, x, z, 6, 15, 0, 30);
	addOres(MWMetadataBlocks.marble.getStateFromMeta(1).getBlock(), world, random, x, z, 6, 15, 0, 30);

	for(int i = 0; i < 2; i++)
	{
		int randPosX = x + random.nextInt(16);
		int randPosY = random.nextInt(250);
		int randPosZ = z + random.nextInt(16);
		(new WorldGenFlowers((BlockFlower)MWBlocks.blue_flower, BlockFlower.EnumFlowerType.DANDELION)).generate(world, random, new BlockPos(randPosX, randPosY, randPosZ));
	}
}

private void addOres(Block block, World world, Random random, int blockXpos, int blockZpos, int MaxVein, int spawnChance, int minY, int maxY) {

	WorldGenMinable minable = new WorldGenMinable(block.getDefaultState(), random.nextInt(MaxVein));
	for (int i = 0; i < spawnChance; i++) {
		int posX = blockXpos + random.nextInt(16);
		int posZ = blockZpos + random.nextInt(16);
		int posY = minY + random.nextInt(maxY - minY);
		minable.generate(world, random, new BlockPos(posX, posZ, posY));
	}

}
}

 

The flower is generated while the ores not, i don't know why. In the main mod class, in the Init event, i register my world generator

 

GameRegistry.registerWorldGenerator(new WorldGenMinableMW(), 1);

 

According to some tutorials the code should be right, so why the ores doesn't generate?

new BlockPos(posX, posZ, posY)

You've made a mistake on that line, so double check it.

Woo i didn't notice that, thanks for the help!
