This is a (very rough!) draft for a potential merger of Entity statuses and Object Data into Entity metadata. I am aware that separating the statuses from metadata was a conscious choice made in 2017. Nonetheless, fragmenting information on entities across three articles seems unhelpful to me. It's also weird to have a list of entities in Entity Metadata but not the others. Another solution to that could be a shared Entities page to be transcluded into all three. Anyway, I'll see how this turns out and ask before merging.

Also, importing the other articles revealed considerable inconsistencies in naming and inheritance hierarchies between the articles. If only keeping track of all this could be made easier somehow... ;)

<bikeshed>
The article is titled Entity Data for consistency with other similar articles. There are arguments to be made on whether or not events/statuses fit the label "data" sufficiently well, though, so simply Entities (same as before the earlier split) might be a better title. That would also make it possible to start calling "entity metadata" simply "entity data". That's what it's called in the source, and I'm not sure why it got called "metadata" in the first place—if an entity's health is "meta", then what isn't?
</bikeshed>

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.

List of entities

Warning.png 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:

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

Metadata

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 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

8 Boolean Boolean
9 Rotations (Float, Float, Float) rotation on x, rotation on y, rotation on z
10 Position Position
11 Optional Position (Boolean, Optional Position) Position is present if the Boolean is set to true.

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

9 Marks item use as finished (finished eating, finished drinking, etc)

This status is not required if you want more control on the server side, this basically finishes the interaction on the client side to decrease the food quantity, arrow quantity, ...

But you can trigger these changes manually through other packets or prevent those changes on the client.

Examples:

  • Create an 'Infinity Bow' without the first arrow in your inventory constantly changing in quantity.
  • Create a custom found that is infinite, and prevent the stack quantity from decreasing.
  • ...

Note: This works together with the 'Hand data' so this will have to be updated accordingly to 'finish' the interaction manually.
