== Packet Format ==
 +
 
 +
Bedrock Edition uses [[Raknet Protocol|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: [[#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: [[#Biome Definition List|Biome Definition List]]
 +
# S→C: Chunks
 +
# 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)
 +
 
 +
 
 +
==== Login ====
 +
 
 +
Sent when the client initially tries to join the server. It is the first packet sent and contains information specific to the player.

  | float

  | 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.

Sent by the client when it falls from a distance onto a block that would damage the player.

This packet should not be used at all by the server, as it can easily be spoofed using a proxy or custom client. Servers should implement fall damage using their own calculations.

Sent by the server to damage the player's armor after being hit.

The packet should never be used by servers as it hands the responsibility over to the player completely, while the server can easily and reliably update the armor damage of players itself.

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.

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.

It includes allowing the player to fly, build, and mine and attack entities. Most of these flags should be checked server-side instead of using this packet only.
  
==== Inventory Slot ====

The client my also send this packet to the server when it updates one of these settings through the in-game settings interface. The server should verify if the player actually has permission to update these settings.

According to the NukkitX Protocol, the server sends the Y coordinate divided by two, and negative if needs to be subtracted by one. Example:
 
  
    int y;
 
    if (packet.getBlockPosition().getY() &gt; 0) {
 
        y = packet.getBlockPosition().getY() * 2;
 
    } else {
 
        y = (packet.getBlockPosition().getY() * -2) - 1;

==== 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.
  
==== Set Local Player As Initialized ====
+
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.

 +
 
 +
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.

 +
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 towards lodestones and to make it spin if the lodestone at a position is no longer there.

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.

This article is about the protocol for the release of Minecraft Bedrock Edition (1.16.20, protocol 408). See Protocol for the Java Edition Protocol.

This is the Bedrock Edition Protocol Documentation. The Bedrock Edition Protocol uses UDP instead of TCP that is used for the Java Edition. Bedrock Edition uses RakNet as its protocol library.

The default Bedrock Edition port is 19132.

Information for this page was obtained from the NukkitX Protocol library, MiNET and gophertunnel.

Packet Format

Bedrock Edition uses 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 zlib, and it seems that packet data can be fed directly into zlib (after being decrypted if encryption is enabled).

Refer to gophertunnel for more information.

Login process

The login process is as follows:

  1. C→S: Login
  2. S→C: Server To Client Handshake
  3. C→S: Client To Server Handshake
  4. S→C: Play Status (Login success)

To spawn, the following packets should be sent, in order, after the ones above:

  1. S→C: Resource Packs Info
  2. C→S: Resource Pack Client Response
  3. S→C: Resource Pack Stack
  4. C→S: Resource Pack Client Response
  5. S→C: Start Game
  6. S→C: Biome Definition List
  7. S→C: Chunks
  8. S→C: Play Status (Player spawn)

If there are no resource packs being sent, a Resource Pack Stack can be sent directly after 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)

Set Time

Sent by the server to update the current time client-side. The client actually advances time client-side by itself, so this packet does not need to be sent each tick. It is merely a means of synchronizing time between server and client.

Packet ID Bound To Field Name Field Type Notes
0x0A Client Time SignedVarInt Time is the current time. The time is not limited to 24000 (time of day), but continues progressing after that.


Start Game

Sent by the server to send information about the world the player will be spawned in.

Packet ID Bound To Field Name Field Type Notes
0x0B Client 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 unofficial servers simply fill the runtime ID of the entity 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.
Player Gamemode SignedVarInt
Spawn Vector3 The spawn position of the player in the world. In servers this is often the same as the world's spawn position found below.
Rotation Vector2 The pitch and yaw of the player
Seed SignedVarInt The seed used to generate the world. Unlike in Java edition, the seed is a 32bit Integer here.
Spawn Biome Type Short
Custom Biome Name String
Dimension SignedVarInt Dimension is the ID of the dimension that the player spawns in. It is a value from 0-2, with 0 being the overworld, 1 being the nether and 2 being the end.
Generator SignedVarInt Generator is the generator used for the world. It is a value from 0-4, with 0 being old limited worlds, 1 being infinite worlds, 2 being flat worlds, 3 being nether worlds and 4 being end worlds. A value of 0 will actually make the client stop rendering chunks you send beyond the world limit.
World Gamemode SignedVarInt The game mode that a player gets when it first spawns in the world. It is shown in the settings and is used if the Player Gamemode is set to 5.
Difficulty SignedVarInt Difficulty is the difficulty of the world. It is a value from 0-3, with 0 being peaceful, 1 being easy, 2 being normal and 3 being hard.
World Spawn BlockCoordinates The block on which the world spawn of the world. This coordinate has no effect on the place that the client spawns, but it does have an effect on the direction that a compass poInts.
Has achievements disabled Boolean Defines if achievements are disabled in the world. The client crashes if this value is set to true while the player's or the world's game mode is creative, and it's recommended to simply always set this to false as a server.
Day cycle stop time SignedVarInt The time at which the day cycle was locked if the day cycle is disabled using the respective game rule. The client will maIntain this time as Boolean as the day cycle is disabled.
EDU offer SignedVarInt Some Minecraft: Education Edition field that specifies what 'region' the world was from, with 0 being None, 1 being RestOfWorld, and 2 being China. The actual use of this field is unknown.
Has Education Edition features enabled Boolean Specifies if the world has education edition features enabled, such as the blocks or entities specific to education edition.
Education Production ID String
Rain level Float The level specifying the Intensity of the rain falling. When set to 0, no rain falls at all.
Lightning level Float The level specifying the Intensity of the thunder. This may actually be set independently from the rain level, meaning dark clouds can be produced without rain.
Has Confirmed Platform Locked Content Boolean
Is Multiplayer Boolean Specifies if the world is a multi-player game. This should always be set to true for servers.
Broadcast To LAN Boolean Specifies if LAN broadcast was Intended to be enabled for the world.
Xbox Live Broadcast Mode VarInt The mode used to broadcast the joined game across XBOX Live.
Platform Broadcast Mode VarInt The mode used to broadcast the joined game across the platform.
Enable commands Boolean If commands are enabled for the player. It is recommended to always set this to true on the server, as setting it to false means the player cannot, under any circumstance, use a command.
Are texture packs required Boolean Specifies if the texture pack the world might hold is required, meaning the client was forced to download it before joining.
GameRules GameRules Defines game rules currently active with their respective values. The value of these game rules may be either 'bool', 'Int32' or 'Float32'. Some game rules are server side only, and don't necessarily need to be sent to the client.
Bonus Chest Boolean Specifies if the world had the bonus map setting enabled when generating it. It does not have any effect client-side.
Map Enabled Boolean Specifies if the world has the start with map setting enabled, meaning each joining player obtains a map. This should always be set to false, because the client obtains a map all on its own accord if this is set to true.
Permission Level SignedVarInt The permission level of the player. It is a value from 0-3, with 0 being visitor, 1 being member, 2 being operator and 3 being custom.
Server Chunk Tick Range Int The radius around the player in which chunks are ticked. Most servers set this value to a fixed number, as it does not necessarily affect anything client-side.
Has Locked Behavior Pack Boolean Specifies if the texture pack of the world is locked, meaning it cannot be disabled from the world. This is typically set for worlds on the marketplace that have a dedicated texture pack.
Has Locked Resource Pack Boolean Specifies if the texture pack of the world is locked, meaning it cannot be disabled from the world. This is typically set for worlds on the marketplace that have a dedicated texture pack.
Is From Locked World Template Boolean Specifies if the world from the server was from a locked world template. For servers this should always be set to false.
Use MSA Gamertags Only Boolean
Is From World Template Boolean Specifies if the world from the server was from a locked world template. For servers this should always be set to false.
Is World Template Option Locked Boolean Specifies if the world was a template that locks all settings that change properties above in the settings GUI. It is recommended to set this to true for servers that do not allow things such as setting game rules through the GUI.
Only Spawn V1 Villagers Boolean A hack that Mojang put in place to preserve backwards compatibility with old villagers. The his never actually read though, so it has no functionality.
Game Version String The version of the game from which Vanilla features will be used. The exact function of this field isn't clear.
Limited World Width Int
Limited World Height Int
Is Nether Type Boolean
Is Force Experimental Gameplay Boolean
Level ID String A base64 encoded world ID that is used to identify the world.
World name String The name of the world that the player is joining. Note that this field shows up above the player list for the rest of the game session, and cannot be changed. Setting the server name to this field is recommended.
Premium World Template Id String 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.
Is Server Side movement enabled Boolean Specifies if the server is authoritative over the movement of the player, meaning it controls the movement of it.
Current Tick Boolean The total time in ticks that has elapsed since the start of the world.
Enchantment Seed SignedVarInt The seed used to seed the random used to produce enchantments in the enchantment table. Note that the exact correct random implementation must be used to produce the correct results both client- and server-side.
Block Palette BlockPalette A list of all blocks registered on the server.

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 packet.

Packet ID Bound To Field Name Field Type Notes
0x0C 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 armour 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.
Flags VarInt Flags is a set of flags that specify certain properties of the player, such as whether or not it can fly and/or move through blocks.
Command permission VarInt A set of permissions that specify what commands a player is allowed to execute.
Action Permissions VarInt Action Permissions is, much like Flags, a set of flags that specify actions that the player is allowed to undertake, such as whether it is allowed to edit blocks, open doors etc.
Permission Level VarInt The permission level of the player as it shows up in the player list built up using the PlayerList packet.
Custom stored permissions VarInt
User Id Long A unique identifier of the player. It appears it is not required to fill this field out with a correct value. Simply writing 0 seems to work.
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 Painting and Add Item Entity packets are used.

Packet ID Bound To Field Name Field Type Notes

Runtime Entity ID VarLong The runtime ID of the entity. The runtime ID is unique for each world session, and entities are generally identified in packets using this runtime ID.
Entity Type String The string entity type of the entity, for example 'minecraft:skeleton'.
Position Vector3 The position to spawn the entity at. If the entity is at a distance that the player cannot see, the entity will still show up if the player moves closer.
Velocity Vector3 The initial velocity the entity spawns with. This velocity will initiate client side movement of the entity.
Rotation Vector3 Pitch, yaw and head yaw
Attributes EntityAttributes A slice of attributes that the entity has. It includes attributes such as its health, movement speed, etc.
Metadata MetadataDictionary A map of entity metadata, which includes flags and data properties that alter in particular the way the entity 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 entity. These links alter the way the entity 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 entity is riding another entity.


Remove Entity

Sent by the server to remove an entity that currently exists in the world from the client-side. Sending this packet if the client cannot already see this entity will have no effect.

Packet ID Bound To Field Name Field Type Notes
0x0E Client Unique Entity Id SignedVarLong The unique ID of the entity to be removed. The unique ID is a value that remains consistent across different sessions of the same world, but most unofficial servers simply fill the runtime ID of the entity out for this field.


Add Item Entity

Sent by the server to make an item entity show up. It is one of the few entities that cannot be sent using the Add Entity packet.

Packet ID Bound To Field Name Field Type Notes
0x0F Client Entity ID Self SignedVarLong The unique ID of the entity. The unique ID is a value that remains consistent across different sessions of the same world, but most unofficial servers simply fill the runtime ID of the entity out for this field.
Runtime Entity ID VarLong The runtime ID of the entity. The runtime ID is unique for each world session, and entities are generally identified in packets using this runtime ID.
Item Item The item that is spawned. It must have a valid ID for it to show up client-side. If it is not a valid item, the client will crash when coming near.
Position Vector3 The position to spawn the entity on. If the entity is at a distance that the player cannot see, the entity will still show up if the player moves closer.
Velocity Vector3 The initial velocity the entity spawns with. This velocity will initiate client side movement of the entity.
Metadata MetadataDictionary A map of entity metadata, which includes flags and data properties that alter in particular the way the entity looks. Flags include ones such as 'on fire' and 'sprinting'. The metadata values are indexed by their property key.
Is From Fishing Boolean Specifies if the item was obtained by fishing it up using a fishing rod. It is not clear why the client needs to know this.


Take Item Entity

Sent by the server when a player picks up an item entity. It makes the item entity disappear to viewers and shows the pick-up animation.

Packet ID Bound To Field Name Field Type Notes
0x11 Client Item Runtime Entity Id VarLong the entity runtime ID of the item that is being taken by another entity. It will disappear to viewers after showing the pick-up animation.
Runtime Entity Id VarLong The runtime ID of the entity that took the item, which is usually a player, but could be another entity like a zombie too.


Move Entity Absolute

Sent by the server to move an entity to an absolute position. It is typically used for movements where high accuracy isn't needed, such as for long range teleporting. This packet is also sent by the client when riding a horse/donkey.

Packet ID Bound To Field Name Field Type Notes
0x12 Server & Client Runtime entity id VarLong The runtime ID of the entity. The runtime ID is unique for each world session, and entities are generally identified in packets using this runtime ID.
Flags byte A combination of flags that specify details of the movement. See below for more info.
Position PlayerLocation
Field Bit Notes

Telported 0x02


Move Player

Sent by players to send their movement to the server, and by the server to update the movement of player entities to other players.

Packet ID Bound To Field Name Field Type Notes
0x13 Server & Client 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.
Position Vector3
Rotation Vector3 Pitch, yaw and head yaw
Mode Byte
On ground Boolean Specifies if the player is considered on the ground. Note that proxies or hacked clients could fake this to always be true, so it should not be taken for granted.
Riding runtime entity id Float The runtime ID of the entity that the player might currently be riding. If not riding, this should be left 0.
Teleportation cause VarLong See below. Only needs to exist if Mode cause is 2 (teleport).
Entity type Byte Only needs to exist if Mode cause is 2 (teleport).

Modes:

Rider Jump

Sent by the client when it jumps while riding an entity that has the WASDControlled entity flag set, for example when riding a horse. According to MiNET this can also be sent from the server to the client, but details on this are unknown.

Packet ID Bound To Field Name Field Type Notes
0x14 Server & Client Jump Strength SignedVarInt The strength of the jump, depending on how long the rider has held the jump button.


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.

Packet ID Bound To Field Name Field Type Notes
0x15 Client Coordinates BlockCoordinates The block position at which a block is updated.
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.

Position Tracking DB Server Broadcast

Sent by the server in response to the 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 towards lodestones and to make it spin if the lodestone at a position is no longer there.
