Various Entities have different metadata fields and status codes.

These are the falid codes for Minecraft Java Edition 1.15.2, for upcoming changes for 1.16.2, see Pre-release protocol#Entity_Metadata The entity ID's are for 1.16.2.

Contents

Mobs

Mobs are spawned via Spawn Mob.

Warning.png 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:

Warning.png These entity IDs are up to date for 1.16.2. Use Data Generators or Burger to get older IDs. If using Burger just replace the version number to what you want to see.

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

11 Direction (VarInt) (Down = 0, Up = 1, North = 2, South = 3, West = 4, East = 5)
