Revision as of 18:46, 24 March 2023

Various Entities have different metadata fields and status codes.

These are the valid codes for Minecraft Java Edition 1.19.4; 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.

Entities

Warning.png These entity IDs are up to date for 1.19.4. Use Data Generators or Burger to get older IDs. If using Burger just replace the version number to what you want to see.

Most entities are spawned via Protocol#Spawn Entity, however, care should be taken for the following cases:

Entities marked in __ blue must be spawned in their own special ways:

Entities marked in __ red must not be spawned at all, as they're server-side only:

  • Marker, more info can be found here

Entities marked in __ yellow are experimental, and must only be spawned if feature flag update_1_20 was enabled:

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
