[1.9] Add world type

[Dijkstra]

I would like to make mod that adds a new world type to minecraft one, that has just the one or two biomes throughout with custom weights, also I would like control block distribution, in my world type.

You should override WorldType#getChunkGenerator, and provide your custom Chunk Provider.

 

If you don't know how to implement the chunk provider, ChunkProviderFlat will help you greatly.

 

EDIT: You should also override WorldType#getChunkManager and do some biome restriction with WorldChunkManager.

Has this method changed name in 1.9.4 and can not find it. Is it "getBiomeProvider" know or is that somthing else.

Yes, It would be BiomeProvider in 1.9.4
