pub struct BlockStates<'a> { /* private fields */ }

The block-state facts service: host.block_states().

Implementations

impl BlockStates<'_>

pub fn replaceable(&self, state: BlockState) -> Option<bool>

BlockState.canBeReplaced(): whether placing a block where state stands replaces it (air, grass, water, snow layers). None for an unknown state, or a host without a game.

pub fn destroy_speed(&self, state: BlockState) -> Option<f32>

How hard state is to break (BlockBehaviour.Properties.destroyTime, as BlockState.getDestroySpeed reads it): stone 1.5, obsidian 50, -1 for a block that can’t be broken. None as for replaceable.

pub fn sound(&self, state: BlockState) -> Option<BlockSoundType>

state’s sounds (BlockState.getSoundType()). None as for replaceable.

pub fn has_block_entity(&self, state: BlockState) -> Option<bool>

BlockState.hasBlockEntity(). None as for replaceable.

pub fn map_color(&self, state: BlockState) -> Option<u8>

BlockState.getMapColor: the state’s MapColor.id, 0 for none (MapColor.NONE). None as for replaceable.

pub fn definition(&self, block: BlockKey) -> Option<Vec<StateProperty>>

The block’s property names and legal serialized values. None without resolved tables.

pub fn matches( &self, state: BlockState, block: BlockKey, constraints: &[StateConstraint], ) -> Option<Result<bool, StateMatchError>>

Match a state against a block and partial property constraints. Unknown properties and values are errors even when the state belongs to a different block. None means the owning thread has no resolved tables or the state is unknown.

pub fn states_of(&self, block: BlockKey) -> Option<BlockStateRange>

The states of block (minecraft:oak_stairs), StateDefinition.getPossibleStates. Local ordinals retain their meaning if world numeric IDs reorder on reload. None before metadata is published, for an unknown block or for a host without a game.
