Hi, i'm doing a school project regarding terrain generation in minecraft and i'm having some problems.

 

I already managed to generate structures ingame but i also need to override minecraft generation to generate the entire world and i can't figure out how.

I know that i can create a new dimension to generate my world but i really would like to do it in the overworld if possible.

 

How can i achieve that?

 

Thank you. 

You need to create a new world type or overwrite the default and in the new WorldType.class you create you can specify a custom ChunkProviderGenerate - look at the default version that is where the generation is done.

Thank you very much it worked.

But now i have another question...

 

I looked into the ChunkProvider and i noticed two methods to generate terrain :

1)

The first one is to create an array of bytes and send it to this method

public Chunk(World world, byte[] ids, byte[] metadata, int chunkX, int chunkZ)

 

Wich doesn't seem too complicated

 

2)

The second is (i think) to generate the terrain data after creating the chunk like this

 

// Generate extended block storage
                for (int y=0; y<16; y++) {
                        chunk.getBlockStorageArray()[y] = new ExtendedBlockStorage(y << 4, true);
                }
                // Generate 16x16 square of grass blocks at y value of 63.
                for (int x=0; x<16; x++) {
                        for (int z=0; z<16; z++) {
                                chunk.getBlockStorageArray()[3].setExtBlockID(x, 15/*y*/, z, Block.grass.blockID);
                        }
                }

 

i don't really understand how it works but it does

 

Which one is the best to use?

Thanks again.
