===== Global palette =====

A table/dictionary/palette mapping nonnegative integers to block states. {{change|The block state IDs can be constructed from this table by multiplying what the Minecraft Wiki calls “block IDs” by 16 and adding the metadata/damage value (or in most programming languages block_id << 4 {{!}} metadata).|Block state IDs are created in a linear fashion based off of order of assignment.  One block state ID allocated for each unique block state for a block; if a block has multiple properties then the number of allocated states is the product of the number of values for each property.  A current list of properties and state ID ranges is found on [http://pokechu22.github.io/Burger/18w15a.html burger].}}

−
{{Change||Alternatively, the vanilla server now includes an option to export the current block state ID mapping, by running <code>java -cp minecraft_server.18w15a.jar net.minecraft.data.Main --reports</code> (use <code>--help</code> for a list of other options).  One can parse the generated <code>blocks.json</code> to convert known block states to and from ids.}}

== 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:

==== Block Change ====
 
−
 
 
−
Fired whenever a block is changed within the render distance.

−
{{Warning2|Changing a block in a chunk that is not loaded is not a stable action.  The Notchian client currently uses a ''shared'' empty chunk which is modified for all block changes in unloaded chunks; while in 1.9 this chunk never renders in older versions the changed block will appear in all copies of the empty chunk.  Servers should avoid sending block changes in unloaded chunks and clients should ignore such packets.}}

==== Chunk Data ====
 
−
{{Main|Chunk Format}}
 
−
{{See also|#Unload Chunk}}
 
−
 
 
−
The server only sends skylight information for chunk pillars in the {{Minecraft Wiki|Overworld}}, it's up to the client to know in which dimenison the player is currently located. You can also infer this information from the primary bitmask and the amount of uncompressed bytes sent.  This packet also sends all block entities in the chunk (though sending them is not required; it is still legal to send them with [[#Update Block Entity|Update Block Entity]] later).
 
−
 
 
−
{{Change||Indexes into the global palette are still used, but since the global palette has changed, behavior is different.}}
 
−
 
 
−
The bits per block value used to index in the global palette is {{change|13|14}}, which is determined by taking the base 2 logarithm of the highest state ID and then rounding up (or alternatively, simply checking how many bits are needed to represent the highest state ID).

This page documents the changes from the last stable Minecraft release (currently 1.18.2, protocol 758) to the current pre-release (currently 22w16b, protocol Snapshot 81). Note that this page contains bleeding-edge information that may not be completely or correctly documented.

One who wishes to commandeer the merging of this into Protocol when an update is made must be sure to respect any changes that may have occurred to the respective packets there.
