good nigths

im a little newby whit terrain generators and im using the guide from

http://www.orangetutorial.com/world-generation/

 

well i alredy has done this code and im generating a block underground using

 

WorldGenMinable minable = new WorldGenMinable(MercenaryModBlocks.girable.getDefaultState() , (minVeinSize + random.nextInt(maxVeinSize - minVeinSize))  );

 

actualy a i wanna spwn a block on the surface to spawn and structure from this block

what object of  WorldGen i must use to spawn a block on the surface ??

Hi,

this is fairly simple.

first of all, you can use this to get the position right on the surface

BlockPos pos = new BlockPos(chunkX*16, 0, chunkZ*16);
pos = world.getHorizon(pos);

 

Now lets say, you want to have little pillar out of cobblestone, lets create a small class:

 

public class CobblePillar extends WorldGenerator
{
@Override
public boolean generate(World world, Random random, BlockPos pos)
{
     for (int i=0; i<=5; i++)
     {
           world.setBlockState(pos.add(0, i, 0), Blocks.cobblestone.getDefaultState(), 2);
     }
     return true;
}
}

 

Now, lets call the code in your generator class:

 

CobblePillar pillar = new CobblePillar();

pillar.generate(world, random, pos);

 

This would be it, have fun

hay

i solved it on other way 

 

            BlockPos posM = world.getTopSolidOrLiquidBlock(pos);

            world.setBlockState(posM, MercenaryModBlocks.hierbaVerde.getDefaultState() );

            minable.generate(world, random, posM );

 

the trou ble is that im using minable  WorldGenMinable and its spawn to many  in the surface the others dont semm to fit how im triying to do i think i have to spend mi time doing mi own WorldGenMercenary or something like

Those sentences though.
