SendBlockAck

Send a block action acknowledgement.

Fields

sequence: i32

SendSystemChat

Send a system chat message.

Fields

content: NbtCompound

The formatted text component as NBT.

action_bar: bool

Whether to display as action bar.

SendPosition

Teleport the current player.

Fields

teleport_id: i32

Teleport ID.

position: Position

Target position.

rotation: Rotation

Target facing direction.

StreamChunks(ChunkPosition)

Stream chunks around a chunk position.

SendGameStateChange

Send a game state change.

Fields

reason: u8

Reason code.

value: f32

Associated value.

PersistChunk(ChunkPosition)

Schedule a chunk for asynchronous persistence.

SpawnDroppedItem

Spawn a dropped item entity in the world.

Fields

position: BlockPosition

Block position where the item spawns.

item_id: i32

Item ID to drop.

count: i32

Item count.

OpenChest(BlockPosition)

Open a chest container at the given position.

OpenCraftingTable

Sends an OpenScreen packet with the 3x3 crafting grid type and attaches a CraftingGrid component to the player entity.

Fields

position: BlockPosition

Block position of the crafting table.

OpenContainer(Container)

Open a custom container window for the current player.

Accepts a Container template value built via Container::builder().

BroadcastBlockAction

Broadcast a BlockAction packet to all connected players.

Used by container/door/note-block plugins for state-change animations (chest lid open/close, door open/close, etc.). The meaning of action_id and action_param depends on the block_id registry value.

Fields

position: BlockPosition

World position of the block.

action_id: u8

Action identifier (block-specific).

action_param: u8

Action parameter (block-specific; for chests this is the number of viewers, 0 = closed).

block_id: i32

Block registry ID (e.g. 185 for chest in 1.21.4).

NotifyContainerViewers

Send a SetContainerSlot to every player viewing the same block-backed container, excluding the current player.

Used by ContainerPlugin to keep co-viewers’ open chests in sync when a slot is mutated by the source player. The server resolves which players are co-viewers by scanning the OpenContainer components.

Fields

position: BlockPosition

World position of the block-backed container.

slot_index: i16

Protocol slot index that changed.

item: Slot

New slot contents to broadcast.

DestroyBlockEntity

Remove a block entity at the given position and dispatch BlockEntityDestroyedEvent with its last state.

Used by ContainerPlugin on chest break to drive the destroy → drop-items chain through the event pipeline. No-op if no block entity exists at the position.

Fields

position: BlockPosition

World position of the block entity to remove.

UnlockRecipe

Unlock a recipe for the current player.

The server inserts the recipe id into the player’s KnownRecipes component, sends a Recipe Book Add S2C packet, and dispatches RecipeUnlockedEvent at Post. No-op if the recipe is already unlocked.

Fields

recipe_id: RecipeId

Stable identifier of the recipe to unlock.

reason: UnlockReason

Why the unlock happened — surfaced on RecipeUnlockedEvent.

LockRecipe

Lock a recipe for the current player.

The server removes the recipe from the player’s KnownRecipes, sends a Recipe Book Remove S2C packet, and dispatches RecipeLockedEvent at Post. No-op if the recipe is not currently unlocked.

Fields

recipe_id: RecipeId

Stable identifier of the recipe to lock.
