UPDATE:

Ok, I got it nearly working. For testing purpose I decided to use lava.

 

 

Thats how it looks so far, but there is one problem.

Is there a way to remove the lava which is over the one block air level?

 

My current code:

    for(int x = 0; x < 16; ++x) {
        for(int z = 0; z < 16; ++z) {
            BiomeBase biomeBase = (BiomeBase)baseBiome[x * 16 + z];
            biomeBase.replaceBlocksForBiome(chunkX * 16 + x, chunkZ * 16 + z, blocks, state, baseBiome, noise);
            
            for(int y = 255; y >= 0; --y) {
                if(y <= this.random.nextInt(4)) {
                    primer.setBlockState((chunkX * 16 + x) & 15, y, (chunkZ * 16 + z) & 15, Blocks.bedrock.getDefaultState());
                    primer.setBlockState((chunkX * 16 + x) & 15, y + 1, (chunkZ * 16 + z) & 15, Blocks.lava.getDefaultState());
                    primer.setBlockState((chunkX * 16 + x) & 15, y + 2, (chunkZ * 16 + z) & 15, Blocks.lava.getDefaultState());
                    primer.setBlockState((chunkX * 16 + x) & 15, y + 3, (chunkZ * 16 + z) & 15, Blocks.lava.getDefaultState());
                    primer.setBlockState((chunkX * 16 + x) & 15, y + 4, (chunkZ * 16 + z) & 15, Blocks.lava.getDefaultState());
                    primer.setBlockState((chunkX * 16 + x) & 15, y + 5, (chunkZ * 16 + z) & 15, Blocks.lava.getDefaultState());
                    primer.setBlockState((chunkX * 16 + x) & 15, y + 6, (chunkZ * 16 + z) & 15, Blocks.air.getDefaultState());
                    
// doesn't remove all lava... not working 
                    if(primer.getBlockState((chunkX * 16 + x) & 15, y + 7, (chunkZ * 16 + z) & 15) == Blocks.lava.getDefaultState())
                        primer.setBlockState((chunkX * 16 + x) & 15, y + 7, (chunkZ * 16 + z) & 15, Blocks.air.getDefaultState());
                    else if(primer.getBlockState((chunkX * 16 + x) & 15, y + 8, (chunkZ * 16 + z) & 15) == Blocks.lava.getDefaultState())
                        primer.setBlockState((chunkX * 16 + x) & 15, y + 8, (chunkZ * 16 + z) & 15, Blocks.air.getDefaultState());
                    else if(primer.getBlockState((chunkX * 16 + x) & 15, y + 9, (chunkZ * 16 + z) & 15) == Blocks.lava.getDefaultState())
                            primer.setBlockState((chunkX * 16 + x) & 15, y + 9, (chunkZ * 16 + z) & 15, Blocks.air.getDefaultState());
                    else if(primer.getBlockState((chunkX * 16 + x) & 15, y + 10, (chunkZ * 16 + z) & 15) == Blocks.lava.getDefaultState())
                            primer.setBlockState((chunkX * 16 + x) & 15, y + 10, (chunkZ * 16 + z) & 15, Blocks.air.getDefaultState());
                    else if(primer.getBlockState((chunkX * 16 + x) & 15, y + 11, (chunkZ * 16 + z) & 15) == Blocks.lava.getDefaultState())
                            primer.setBlockState((chunkX * 16 + x) & 15, y + 11, (chunkZ * 16 + z) & 15, Blocks.air.getDefaultState());
                    else if(primer.getBlockState((chunkX * 16 + x) & 15, y + 12, (chunkZ * 16 + z) & 15) == Blocks.lava.getDefaultState())
                            primer.setBlockState((chunkX * 16 + x) & 15, y + 12, (chunkZ * 16 + z) & 15, Blocks.air.getDefaultState());
                    else if(primer.getBlockState((chunkX * 16 + x) & 15, y + 13, (chunkZ * 16 + z) & 15) == Blocks.lava.getDefaultState())
                            primer.setBlockState((chunkX * 16 + x) & 15, y + 13, (chunkZ * 16 + z) & 15, Blocks.air.getDefaultState());
                    else if(primer.getBlockState((chunkX * 16 + x) & 15, y + 14, (chunkZ * 16 + z) & 15) == Blocks.lava.getDefaultState())
                            primer.setBlockState((chunkX * 16 + x) & 15, y + 14, (chunkZ * 16 + z) & 15, Blocks.air.getDefaultState());
                }
            }
        }
    }

So everything above y + 6 should not generate the lava spots. (lava lakes are ok, but thats a future task for me)

 

Thx in advance.

Hi,

 

I've got a question (which is a problem, too). So, I'm currently working on my own world generator for my

own dimension, but now I'm wondering how to generate bedrock at the bottom of the world.

 

Currently it's not generating in my world and when you dig down you just fell out of the world.

So does anyone got an idea how to genereate bedrock in a world generator cause I'm unable to find

out how Mojang does it and my own code isn't working (replaceBlockBiomes code...)

 

Thats my code which I tried:

private void replaceBlocksForBiome(int chunkX, int chunkZ, Block[] blocks, IBlockState[] state, BiomeGenBase[] baseBiome, float[] noise, ChunkPrimer primer) {
    ChunkProviderEvent.ReplaceBiomeBlocks event = new ChunkProviderEvent.ReplaceBiomeBlocks(this, chunkX, chunkZ, primer, world);
    MinecraftForge.EVENT_BUS.post(event);
    
    if(event.getResult() == Result.DENY) return;
    
    for(int x = 0; x < 16; ++x) {
        for(int z = 0; z < 16; ++z) {
            BiomeBase biomeBase = (BiomeBase)baseBiome[x * 16 + z];
            biomeBase.replaceBlocksForBiome(chunkX * 16, chunkZ * 16, blocks, state, baseBiome, noise);

            blocks[(z * 16 + x) * 256] = Blocks.bedrock;
            state[(z * 16 + x) * 256] = Blocks.bedrock.getDefaultState();
        }
    }
}

[i don't even know if that code is correct, I just now it gives me no errors]

 

For generating stuff I'm using OpenSimplexNoise and currently just generating a few layers of stone... no grass, no dirt, no hills, no caves etc.

 

Thx in advance.

replaceBlocksForBiome is intended for replacing the top 4 blocks of stone with grass or sand (or at least, that's what Minecraft uses it for).  The bottom bedrock is handled by the chunk provider the last time I looked at it.

Ah, ok. Just thought I can use it for that purpose, too, because some mods do it [MC 1.7.10].

So how is the chunk provider doing this? Everytime when I search for "bedrock" in the "ChunkProviderGenerate" from Mojang I can't find it. And "replaceBlocksForBiome" is a method inside of the chunk provider.

 

Been a while since I looked at it, TBH.

If you look for usages of the

Blocks.bedrock

field, you'll see that it's used in

BiomeGenBase#generateBiomeTerrain

. This is called from

BiomeGenBase#genTerrainBlocks

, which is called from

ChunkProviderGenerate#replaceBlocksForBiome

.

 

Each biome generates its own terrain (including bedrock) from this method.

Ok, thx. Now its mostly working..... I just broke MC down to 2FPS because I wanted to generate over the bedrock something else like which is generated like the bedrock.....

 

Any idea how my code must look to generate in (java) level 256 bedrock and in (java) 255 for example dirt?
