Implementations

impl ShulkerBoxBlockEntity

pub fn new(level: Weak<World>, pos: BlockPos, state: BlockStateId) -> Self

Creates a new shulker box block entity.

fn update_animation( &self, world: &Arc<World>, pos: BlockPos, state: BlockStateId, )

fn move_collided_entities( &self, world: &Arc<World>, pos: BlockPos, state: BlockStateId, )

pub fn shulker_box_as_item(&self, state: BlockStateId) -> ItemStack

Builds the item form of a placed, possibly-filled shulker box. Vanilla ShulkerBoxBlockEntity.collectComponents() + BaseContainerBlockEntity.collectImplicitComponents(CONTAINER).

pub fn get_progress_delta_aabb<I: Space>( size: f32, direction: Direction, progress_from: f32, progress_to: f32, position: DVec3, ) -> Aabb<DVec3, I>

Calculates the bounding box of a shulker during its opening animation.

The bounds are expanded in the opening direction based on the animation progress.

pub fn get_bounding_box(&self, state: BlockStateId) -> BlockLocalAabb

Block-local bounds of the box including the lid at its current progress.

pub fn can_open( &self, state: BlockStateId, world: &Arc<World>, pos: BlockPos, ) -> bool

Returns whether the shulker box can open

pub fn is_empty(&self) -> bool

Checks if the block entity’s container has any items

pub fn collect_components(&self) -> ItemContainerContents

Collect all the items inside the shulker box into an ItemContainerContents

Panics

Panics if shulker box somehow has more than 256 slots. This should never happen

pub fn progress(&self, partial_tick: f32) -> f32

Interpolated progress for smooth rendering between ticks.

pub fn animation_status(&self) -> AnimationStatus

Get the current animation state

Trait Implementations

impl BlockEntity for ShulkerBoxBlockEntity

fn base(&self) -> &BlockEntityBase

Returns the common metadata owned by this block entity.

fn tick(&self, world: &Arc<World>)

Called every game tick for ticking block entities.

fn trigger_event(&self, kind: i32, data: i32) -> bool

Handles a block event delegated by the owning block behavior.

fn load_additional(&self, nbt: &BaseNbtCompound<'_>)

Loads additional data from NBT.

fn save_additional(&self, nbt: &mut NbtCompound)

Saves additional data to NBT.

fn apply_components_from_item(&self, item: &ItemStack)

Vanilla BlockEntity.applyComponentsFromItemStack.

fn container_ref(&self) -> Option<ContainerRef>

Returns the independently lockable container capability owned by this entity.

fn get_type(&self) -> BlockEntityTypeRef

Returns the type of this block entity.

fn get_block_pos(&self) -> BlockPos

Returns the position of this block entity in the world.

fn get_block_state(&self) -> BlockStateId

Returns the current block state associated with this entity.

fn is_valid_block_state(&self, state: BlockStateId) -> bool

Returns whether this entity’s registered type accepts state.

fn on_block_state_changed(&self, _state: BlockStateId)

Called after the cached block state changes.

fn on_set_removed(&self)

Called after each invocation that marks this entity removed.

fn on_clear_removed(&self)

Called after this entity transitions from removed back to active.

fn set_changed(&self)

Called when the block entity’s data changes.

fn get_level(&self) -> Option<Arc<World>>

Gets the world reference if still valid.

fn pre_remove_side_effects(&self, pos: BlockPos, state: BlockStateId)

Called before the block entity is removed to handle side effects.

fn load_with_components(&self, nbt: &BorrowedNbtCompound<'_>)

Loads entity-specific data and the base block-entity component map.

fn load_with_owned_components(&self, nbt: &NbtCompound) -> Result<(), Error>

Loads entity data from an owned command/runtime compound.

fn save_custom_only(&self) -> NbtCompound

Saves only entity-specific data, excluding vanilla type and position metadata.

fn save_without_metadata(&self) -> NbtCompound

Saves entity-specific data and stored components without position/type metadata.

fn save_with_full_metadata(&self) -> NbtCompound

Saves command-visible data together with vanilla block-entity metadata.

fn get_update_tag(&self) -> Option<NbtCompound>

Returns the NBT data to send to clients for initial sync.

fn game_event_listener(&self) -> Option<SharedGameEventListener>

Returns this entity’s fixed game-event listener, if it provides one.

impl DowncastType for ShulkerBoxBlockEntity

const TYPE_KEY: DowncastTypeKey
