{{exclusive|bedrock}}

This article documents the {{BE}} '''protocol''' for [[Minecraft:Minecraft Wiki:Projects/wiki.vg merge/Bedrock Protocol version numbers|1.16.220, protocol 431]].
The ''Bedrock Edition'' protocol uses [[Minecraft:wikipedia:User Datagram Protocol|UDP]] instead of [[Minecraft:wikipedia:Transmission Control Protocol|TCP]] that is used for the ''[[Minecraft:Java Edition]]''.
''Bedrock Edition'' uses [[Minecraft:RakNet]] as its protocol library.

The default ''Bedrock Edition'' port is 19132.

Information for this page was obtained from the [https://github.com/NukkitX/Protocol NukkitX Protocol library], [https://github.com/NiclasOlofsson/MiNET MiNET] and [https://github.com/Sandertv/gophertunnel gophertunnel].

== Packet Format ==

Bedrock Edition uses [[Minecraft:RakNet]] as its protocol library, so the packets are sent that way. The UDP protocol specifies packet length, so unlike Java Edition and TCP which deal with raw data streams packets are not length-prefixed. Packets seem to always use compression and can also use encryption. Multiple packets can also be batched into a single packet.
Packet compression uses [https://zlib.net/ zlib], and it seems that packet data can be fed directly into zlib (after being decrypted if encryption is enabled).
<br><br>
Refer to [https://github.com/Sandertv/gophertunnel/blob/19c96251a36a39d9ffb938053410852e811755e3/minecraft/protocol/packet/decoder.go#L58 gophertunnel] for more information.

== Login process ==
The login process is as follows:
# C→S: [[#Request Network Settings|Request Network Settings]]
# S→C: [[#Network Settings|Network Settings]]
# C→S: [[#Login|Login]]
# S→C: [[#Server To Client Handshake|Server To Client Handshake]]
# C→S: [[#Client To Server Handshake|Client To Server Handshake]]
# S→C: [[#Play Status|Play Status]] (Login success)

To spawn, the following packets should be sent, in order, after the ones above:
# S→C: [[#Resource Packs Info|Resource Packs Info]]
# C→S: [[#Resource Pack Client Response|Resource Pack Client Response]]
# S→C: [[#Resource Pack Stack|Resource Pack Stack]]
# C→S: [[#Resource Pack Client Response|Resource Pack Client Response]]
# S→C: [[#Start Game|Start Game]]
# S→C: [[#Creative Content|Creative Content]]
# S→C: [[#Biome Definition List|Biome Definition List]]
# S→C: [[#Level Chunk|Level Chunk]]
# S→C: [[#Play Status|Play Status]] (Player spawn)

If there are no resource packs being sent, a [[#Resource Pack Stack|Resource Pack Stack]] can be sent directly after [[#Resource Packs Info|Resource Packs Info]] to avoid the client responses.

== Packets ==
Please note that some packet ids are missing, so they don't line up.
The following packet ids are missing:
0x10, 0x74, 0x7F, 0x80
(16, 116, 127, 128)

 | Specifies if the world had the bonus map setting enabled when generating it. It does not have any effect client-side.
 |-
 | Map Enabled
 | Boolean

 | A UUID specific to the premium world template that might have been used to generate the world. Servers should always fill out an empty String for this.
 |-
 | Is Trial
 | Boolean
 | Specifies if the world was a trial world, meaning features are limited and there is a time limit on the world.
 |-
 | Movement type
 | VarInt
 | Specifies the movement type as an ordinal - client authoritative (MovePlayerPacket), server authoritative (PlayerAuthInputPacket), or server authoritative with rewind
 |-
 | Movement rewind size

 |-
 | Block Properties
 | Block Properties
 | An array of string followed by tag for each custom block on the server.
 |-
 | Itemstates
 | Itemstates
 | A list of all items with their legacy IDs which are available in the game. Failing to send any of the items that are in the game will crash mobile clients. Each entry in the array consists of a string, followed by a Little Endian Short ID, followed by a boolean if the item is component based

 | Multiplayer Correlation ID
 | String
 | A unique ID specifying the multi-player session of the player. A random UUID should be filled out for this field.
 |-
 | Inventories server authoritative
 | Boolean
 | If true, the ItemStackRequestPacket is used to send inventory transactions. Otherwise, the InventoryTransactionPacket is used.
 |}

In order to use custom blocks, you must add <code>data_driven_items</code> as an <code>ExperimentData</code> in this packet with its value set to true [whether you need to add the experiment data to the resource pack process, like with items, has been untested]. A boilerplate representation of the NBT sent for a custom block is as follows:

<syntaxhighlight lang="json">
{
  "components": {
    "minecraft:entity_collision": {
      "enabled": 0b,
      "origin": [
        -8.0f,
        0.0f,
        -8.0f
      ],
      "size": [
        16.0f,
        16.0f,
        16.0f
      ]
    },
    "minecraft:material_instances": {
      "mappings": {},
      "materials": {
        "*": {
          "ambient_occlusion": 1b,

        }
      }
    },
    "minecraft:unit_cube": {}
  }
}

The block runtime ID is determined by the second part of the namespace, in alphabetical order. If the block is named <code>wikivg:aaa</code>, it will be placed at the beginning of the block runtime states. If the block is named <code>wikivg:zzz</code>, it will be placed at the end of the palette [most likely - naming a block "snow" caused other block states to shift].

==== Add Player ====

Sent by the server to make a player entity show up client-side. It is one of the few entities that cannot be sent using the [[#Add Entity|Add Entity]] packet.

 |-
 |rowspan="19"| 0x0C
 |rowspan="19"| Client
 | UUID
 | UUID
 | UUID is the UUID of the player. It is the same UUID that the client sent in the Login packet at the start of the session. A player with this UUID must exist in the player list (built up using the Player List packet) for it to show up in-game.
 |-
 | Username
 | String
 | Username is the name of the player. This username is the username that will be set as the initial name tag of the player.
 |-
 | Entity ID Self
 | SignedVarLong
 | The unique ID of the player. The unique ID is a value that remains consistent across different sessions of the same world, but most unoffical servers simply fill the runtime ID of the player out for this field.
 |-
 | Runtime Entity ID
 | VarLong
 | The runtime ID of the player. The runtime ID is unique for each world session, and entities are generally identified in packets using this runtime ID.
 |-
 | Platform Chat ID
 | String
 | An identifier only set for particular platforms when chatting (presumably only for Nintendo Switch). It is otherwise an empty string, and is used to decide which players are able to chat with each other.
 |-
 | Position
 | Vector3
 | The position to spawn the player at. If the player is at a distance that the viewer cannot see, the player will still show up if the viewer moves closer.
 |-
 | Velocity
 | Vector3
 | The initial velocity the player spawns with. This velocity will initiate client side movement of the player.
 |-
 | Rotation
 | Float
 | Pitch, yaw and head yaw
 |-
 | Held Item
 | Item
 | The item that the player is holding. The item is shown to the viewer as soon as the player itself shows up. Needless to say that this field is rather pointless, as additional packets still must be sent for armor to show up.
 |-
 | Metadata
 | MetadataDictionary
 | A map of entity metadata, which includes flags and data properties that alter in particular the way the player looks. Flags include ones such as 'on fire' and 'sprinting'. The metadata values are indexed by their property key.

 |-
 | Links
 | Links
 | A list of entity links that are currently active on the player. These links alter the way the player shows up when first spawned in terms of it shown as riding an entity. Setting these links is important for new viewers to see the player is riding another entity.
 |-
 | Device ID
 | String
 | The device ID set in one of the files found in the storage of the device of the player. It may be changed freely, so it should not be relied on for anything.
 |-
 | Device OS
 | Int
 | The build platform/device OS of the player that is about to be added, as it sent in the Login packet when joining.
 |}



==== Add Entity ====

Sent by the server to spawn an entity to the player. It is used for every entity except other players, paintings and items, for which the [[#Add Player|Add Player]], [[#Add Painting|Add Painting]] and [[#Add Item Entity|Add Item Entity]] packets are used.

==== Update Block ====

Sent by the server to update a block client-side, without resending the entire chunk that the block is located in. It is particularly useful for small modifications like block breaking/placing.

 |-
 | Block Runtime ID
 | VarInt
 | The runtime ID of the block that is placed at Position after sending the packet to the client. The runtime ID must point to a block sent in the list in the Start Game packet.
 |-
 | Flags
 | VarInt
 | See below. Flags is a combination of flags that specify the way the block is updated client-side. It is a combination of the flags below, but typically sending only the Network flag is sufficient.
 |-
 | Layer
 | VarInt
 | The world layer on which the block is updated. In Bedrock, multiple blocks can be put in the same location using layers. The second layer is usually used for liquids, so blocks can be inside a liquid. For most blocks, this is the first layer, as that layer is the default layer to place blocks on, but for blocks inside of each other, this differs. As this system is designed with liquids, there may be bugs when using this to place blocks inside each other. For example, placing an interactable block such as an item frame on the second layer can cause a game crash if the player tries to interact with it.

Bedrock needs either a valid block position, with an actual block at that position, or an entity ID for this to work. The entity must have CONTAINER_BASE_SIZE metadata, or the block must be a container. The entity ID is used for minecart chests etc. but any entity will work. If the entity has NAMETAG metadata this will be used as the container name.

==== Show Store Offer ====

Sent by the server to show a Marketplace store offer to a player. It opens a window client-side that displays the item.

The packet only works on partnered servers: Servers that are not partnered will not have a store button show up on the in-game pause menu and will, as a result, not be able to open store offers on the client side. Sending the packet does therefore not work when using a proxy that is connected to with the domain of one of the partnered servers.

==== Network Chunk Publisher Update ====

Sent by the server to change the point around which chunks are and remain loaded. 

This is useful for minigame servers, where only one area is ever loaded, in which case the [[#Network Chunk Publisher|Network Chunk Publisher]] packet can be sent in the middle of it, so that no chunks ever need to be additionally sent during the course of the game.

In reality, the packet is not extraordinarily useful, and most servers just sent it constantly at the position of the player. 

If the packet is not sent at all, no chunk will be shown to the player, regardless of where they are sent.

==== Player Enchant Options ====

Sent by the server to update the enchantment options displayed when the user opens the enchantment table and puts an item in.

This packet was added in 1.16 and allows the server to decide on the enchantment that can be selected by a player. The player should be sent once for every slot update of the enchantment table. The vanilla server sends an empty packet when the player first opens the enchantment table (air is is present in the enchantment table slot) and sends a packet with actual enchantments in it when items are put in that can have enchantments.

Sent by the client to change item stacks in an inventory. 

Added in 1.16, is essentially a replacement of the [[#Inventory Transaction|Inventory Transaction]] packet for inventory specific actions, such as moving items around or crafting.

The [[#Inventory Transaction|Inventory Transaction]] packet is still used for actions such as placing blocks and interacting with entities.

==== Item Stack Response ====

Sent by the server in response to an [[#Item Stack Request|Item Stack Request]] packet from the client.

This packet is used to either approve or reject ItemStackRequests from the client. If a request is approved, the client will simply continue as normal. If rejected, the client will undo the actions so that the inventory should be in sync with the server again.

==== Emote List ====

Sent by the client every time it joins the server and when it equips new emotes. It may be used by the server to find out which emotes the client has available. If the player has no emotes equipped, this packet is not sent.

Under certain circumstances, this packet is also sent from the server to the client, but more testing is needed for this.

==== Position Tracking DB Server Broadcast ====

Sent by the server in response to the [[#Position Tracking DB Client Request|Position Tracking DB Client Request]] packet. Thus packet is, as of 1.16, currently only for lodestones. The server maintains a database with tracking IDS and their position and dimension. The client will request these tracking IDs, (NBT tag set on the lodestone compass with the tracking ID?) and the server will respond with the status of those tracking IDs.

What is actually done with the data sent depends on what the client chooses to do with it. For the lodestone compass, it is used to make the compass point toward lodestones and to make it spin if the lodestone at a position is no longer there.

==== Position Tracking DB Client Request ====

Sent by the client to request the position and dimension of a 'tracking ID'. These IDs are tracked in a database by the server. In 1.16, this is used for lodestones.

The client will sent this request to find the position a lodestone compass needs to point to. If found, it will point to the lodestone. If not, it will start spinning around.

A [[#Position Tracking DB Server Broadcast|Position Tracking DB Server Broadcast]] packet should be sent in response to this packet.
