Revision as of 19:26, 2 June 2016

This page documents the changes from the last stable Minecraft release (currently 1.9.4, protocol 110) to the current pre-release (currently 1.10-pre1, protocol 204). Note that this page contains bleeding-edge information that may not be completely or correctly documented.

One who wishes to commandeer the merging of this into Protocol when an update is made must be sure to respect any changes that may have occurred to the respective packets there.

New/modified data types

Mobs

Mobs are spawned via Spawn Mob. There are two extra mob types in the code that refer to mobs classes that can never spawn: Mob and Monster (they are always subclasses, aka another more specific type).

Entity Metadata

Note that entity metadata is a totally distinct concept from block metadata. All entities must send at least one item of metadata, in most cases this will be the health item.

An Entity Metadata is an array of entries, each of which looks like the following:

Name Type Meaning
Index Unsigned Byte Unique index key determining the meaning of the following value, see the table below. If this is 0xff then the it is the end of the Entity Metadata array and no more is read.
Type Optional Byte Enum Only if Index is not 0xff; the type of the index, see the table below
Value Optional value of Type Only if Index is not 0xff: the value of the metadata field
Value of Type field Type of Value field Notes
0 Byte
1 VarInt
2 Float
3 String
4 Chat
5 Slot
6 Boolean
7 Rotation 3 floats: rotation on x, rotation on y, rotation on z
8 Position
9 OptPosition (Boolean + Optional Position) Position is present if the Boolean is set to true
10 Direction (VarInt) (Down = 0, Up = 1, North = 2, South = 3, West = 4, East = 5)
11 OptUUID (Boolean + Optional UUID) UUID is present if the Boolean is set to true
12 BlockID (VarInt) id << 4 | data

Entity classes also recursively use fields from classes they extend.
