Expand description

Read-only level access needed by block behavior and worldgen predicates.

Required Methods§

Source

fn get_block_state(&self, pos: BlockPos) -> BlockStateId

Gets the block state at a position.

Source

fn raw_brightness(&self, pos: BlockPos, sky_darkening: u8) -> u8

Returns vanilla raw brightness at a position after sky darkening.

Source

fn min_y(&self) -> i32

Returns the minimum build height.

Source

fn height(&self) -> i32

Returns the build height.

Source

fn sea_level(&self) -> i32

Returns the dimension’s sea level.

Provided Methods§

Source

fn get_block_entity(&self, pos: BlockPos) -> Option<SharedBlockEntity>

Gets the block entity at a position when this level surface supports it

Source

fn is_face_sturdy( &self, state: BlockStateId, pos: BlockPos, direction: Direction, ) -> bool

Mirrors vanilla BlockState.isFaceSturdy with full-face support.

Source

fn is_face_sturdy_for( &self, state: BlockStateId, pos: BlockPos, direction: Direction, support_type: SupportType, ) -> bool

Mirrors vanilla BlockState.isFaceSturdy for a specific support type.

Lightweight and worldgen views default to extracted support shapes. Live views override this to dispatch through block behavior for dynamic world-dependent shapes.
