Entity metadata

Various Entities have different metadata fields and status codes.

Mobs

Mobs are spawned via Spawn Mob.

Some entities (marked in yellow) should only be spawned using Spawn Object and their Object ID. While they also have an entity ID, this ID is only used internally. Servers should not attempt to spawn these entities using Spawn Mob with that entity ID, although clients should accept such packets if they appear.

Additionally, a few other entities (marked in blue) must be spawned in their own special ways:

• Paintings should be spawned using Spawn Painting
• XP orbs should be spawned using Spawn Experience Orb.

Objects

Objects are spawned via Spawn Object. See Object Data for more details.

Object IDs and Entity IDs are different. Most objects also have an entity ID, but should only ever be spawned via Spawn Object.

Since release 1.6, all minecarts are spawned with object type 10 and their functionality is then specified in the Data field within the packet. Also, their visual appearance may be sent via the Entity Metadata packet.

Entity Metadata Format

Note that entity metadata is a totally distinct concept from block metadata. It is not required to send all metadata fields, or even any metadata fields, so long as the terminating entry is correctly sent.

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 VarInt 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	OptChat (Boolean + Optional Chat)	Chat is present if the Boolean is set to true
6	Slot
7	Boolean
8	Rotation	3 floats: rotation on x, rotation on y, rotation on z
9	Position
10	OptPosition (Boolean + Optional Position)	Position is present if the Boolean is set to true
11	Direction (VarInt)	(Down = 0, Up = 1, North = 2, South = 3, West = 4, East = 5)
12	OptUUID (Boolean + Optional UUID)	UUID is present if the Boolean is set to true
13	OptBlockID (VarInt)	0 for absent otherwise, id << 4 | data
14	NBT
15	Particle

Entity classes also recursively inherit fields from classes they extend.
