Entity metadata

Various Entities have different metadata fields and status codes.

These are the valid codes for Minecraft Java Edition 1.19; 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 Protocol#Spawn Entity.

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

• XP orbs should be spawned using Spawn Experience Orb.
• Players should be spawned using Spawn Player.

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

These entity IDs are up to date for 1.19. 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	VarLong
