Various Entities have different metadata fields and status codes.

These are the valid codes for Minecraft Java Edition 1.17; for upcoming snapshots, see Pre-release protocol#Entity Metadata.

Because this is always updated late, only valid for the latest version and not computer parseable, Bixilon wrote PixLyzer. Burger burger might help.

Mobs

Most entities are spawned via Spawn Living Entity.

Warning.png Some entities (marked in yellow) should only be spawned using Spawn Entity. Servers should not attempt to spawn these entities using Spawn Living Entity 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:

Furthermore, the marker entity (marked in red) must not be spawned, as it is server-side only. Find out more about the marker here.

Warning.png These entity IDs are up to date for 1.17. Use Data Generators or Burger to get older IDs. If using Burger just replace the version number to what you want to see.

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

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 (implies air); otherwise, a block state ID as per the global palette
14 NBT
15 Particle
16 Villager Data 3 VarInts: villager type, villager profession, level
17 OptVarInt 0 for absent; 1 + actual value otherwise. Used for entity IDs.
18 Pose A VarInt enum: 0: STANDING, 1: FALL_FLYING, 2: SLEEPING, 3: SWIMMING, 4: SPIN_ATTACK, 5: SNEAKING, 6: LONG_JUMPING, 7: DYING
