Entity metadata

Various Entities have different metadata fields and status codes.

These are the valid codes for Minecraft Java Edition 1.20.2; 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

These entity IDs are up to date for 1.20.2. 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:

• Experience Orb, should be spawned using Spawn Experience Orb

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

• Marker, more info can be found here.

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	VarInt Enum	Only if Index is not 0xff; the type of the index, see the table below
Value	Varies	Only if Index is not 0xff: the value of the metadata field, see the table below

Type	Name	Value	Notes
0	Byte	Byte
1	VarInt	VarInt
2	VarLong	VarLong
3	Float	Float

18	Villager Data	(VarInt, VarInt, VarInt)	villager type, villager profession, level (See below.)
