Implementations

impl PistonMovingBlockEntity

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

Creates the default instance used while loading a piston block entity.

pub fn new_moving( world: Weak<World>, pos: BlockPos, state: BlockStateId, moved_state: BlockStateId, direction: Direction, extending: bool, source_piston: bool, ) -> Self

Creates a moving block or source-piston entity.

pub fn is_extending(&self) -> bool

Returns whether this block is extending.

pub fn direction(&self) -> Direction

Returns the piston facing direction.

pub fn is_source_piston(&self) -> bool

Returns whether this entity represents the source piston or its head.

pub fn moved_state(&self) -> BlockStateId

Returns the state being moved.

pub fn last_ticked(&self) -> i64

Returns the last game time at which this entity ticked.

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

Returns interpolated movement progress.

pub fn movement_direction(&self) -> Direction

Returns the movement direction, which reverses while retracting.

pub fn push_direction(&self) -> Direction

Returns the direction used for the final neighbor notification.

pub fn collision_boxes( &self, world: &dyn LevelReader, pos: BlockPos, ) -> BlockCollisionBoxes

Resolves the transient collision boxes at the current progress.

pub fn final_tick(&self, world: &Arc<World>) -> bool

Completes an in-flight moving block before its piston starts retracting.

Trait Implementations

impl BlockEntity for PistonMovingBlockEntity

fn base(&self) -> &BlockEntityBase

Returns the common metadata owned by this block entity.

fn pre_remove_side_effects(&self, _pos: BlockPos, _state: BlockStateId)

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

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

Loads additional data from NBT.

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

Saves additional data to NBT.

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

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

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

Called every game tick for ticking block entities.

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 trigger_event(&self, _param_a: i32, _param_b: i32) -> bool

Handles a block event delegated by the owning block behavior.

fn save_custom_only(&self) -> NbtCompound

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

fn save_with_full_metadata(&self) -> NbtCompound

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

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

Returns the independently lockable container capability owned by this entity.

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

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

impl DowncastType for PistonMovingBlockEntity

const TYPE_KEY: DowncastTypeKey

The process-wide key for this concrete type.
