Entity metadata

Revision as of 05:17, 9 January 2020 by Pokechu22 (talk | contribs) (→‎Entity Metadata Format: Work around the caching -- had I read the phabricator issue more closely, I'd've seen https://phabricator.wikimedia.org/T191574#4607891 which mentions how to bypass that. Much cleaner than what I thought I needed to do...)

Various Entities have different metadata fields and status codes.

Contents

Unmerged information

Warning.png Unmerged content from 1.14.4. This needs to be merged eventually but I don't want to do it now.

Warning.png Entity metadata shifted in 19w08a; not all entities are copied here. All subclasses of entity had shift of 1; all subclasses of living had a second shift (2 total). All entities listed in the article have been updated, but there are ones not listed here.

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

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:

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.
