Talk:Chunk Format

Actually the 0x33 Map chunk is still used by vanilla 1.4.6 server to send individual chunks; I'm seeing this packet in the protocol disassembly when the player is moving across chunk boundaries. I personally think the server sends 0x38 only when entering a world (start of session or transition to / from the Nether / End) and otherwise it sends 0x33 for each individual chunk that's coming into player's viewdistance.

1.8 Chunk Format

The section describing how the chunk data is stored is... either completely wrong or very misleading. By reading it I got the idea that the data was stored like this:

   BVVLSbBVVLSbBVVLSb...
     (3 sections)
     where B: block and metadata array
           V: varint (1st one for # of bits, 2nd one for # of elements)
           L: light data
           S: skylight data (may or may not be there)
           b: biome data (for each section? wat?)

when in reality it's stored like this:

   BBBBBLLLLLSSSSSb
     (5 sections)
     where B: block and metadata array
           L: light data
           S: skylight data
           b: biome data (only one this time)

and there are no varints.
