Remember that this page is a WIP. Come back later to see a more complete page.

Heads up!

This article is about the protocol for an outdated release of Minecraft Bedrock Edition (1.14.60, protocol 390). 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:

C→S: Login
S→C: Server To Client Handshake
C→S: Client To Server Handshake
S→C: Play Status (Login success)

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

S→C: Resource Packs Info
C→S: Resource Pack Client Response
S→C: Resource Pack Stack
C→S: Resource Pack Client Response
S→C: Start Game
S→C: Biome Definition List
S→C: Chunks
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

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.

SetTime is 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 synchronising time between server and client.

Start Game

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.
		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.
		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.
		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.
		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.
		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.

Add Player

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 Player is sent by the server to the client to make a player entity show up client-side. It is one of the few entities that cannot be sent using the AddActor packet.

Add Entity

Packet ID	Bound To	Field Name	Field Type	Notes
0x0D	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.
		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.

Sent by the server to the client 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.

Remove Entity

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.

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.

Add Item Entity

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.

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

Take Item Entity

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.
0x11	Client	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.

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.

Move Entity Absolute

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
On ground	0x01	If the entity is touching the ground
Telported	0x02

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.

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:

0: Normal
1: Reset
2: Teleport
3: Rotation

Teleportation causes:

0: Unknown
1: Projectile
2: Chorus fruit
3: Command
4: Behavior

Rider Jump

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.

Sent by the client to the server 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.

Update Block

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.

Field	Bit	Notes
Neighbors	0x01
Network	0x02
No Graphic	0x04
Priority	0x08

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.

Add Painting

Packet ID	Bound To	Field Name	Field Type	Notes
0x16	Client	Unique Entity Id	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.
		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.

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.
