2011-9-29
- Beta 1.9 pre2.
- Protocol version is now 19
- Four packets changed:
- The change affects the "slot" datatype. This type consists of at least a short (item_id). If this id isn't
-1
, a byte (count) and a short (uses) follow. - From 1.9pre2 onward, additional data is sent but only for certain item_ids. This means the protocol is no longer context free. The additional data is at least a short. If this short isn't -1, a byte[] array follows, containing gzipped NBT data
- The format of the NBT is as follows
COMPOUND
LIST: 'ench'
SHORT: 'id'
SHORT: 'lvl'
END
END
- So far only this format, with 'id' and 'lvl' set to
2
and1
respectively, has been seen.
