Struct BlockState 

pub struct BlockState(/* private fields */);

A 1.8 block state: block_id << 4 | meta, exactly the wire / chunk-section value.

Implementations

impl BlockState

pub const AIR: BlockState

Air (raw 0).

pub const fn from_raw(raw: u16) -> Option<BlockState>

Wraps a raw id << 4 | meta value; None if the block id is not a 1.8 block.

pub fn from_raw_vanilla(raw: u16) -> BlockState

Vanilla’s chunk-read mapping: unknown block ids and unregistered metas become air.

pub fn is_registered(self) -> bool

true when vanilla 1.8.9 has a block state for this (id, meta); otherwise it reads as air.

pub const fn new(block: Block, meta: u8) -> BlockState

Builds a state from a block and metadata (meta & 15).

pub const fn raw(self) -> u16

The raw id << 4 | meta value.

pub const fn block(self) -> Block

The block type.

pub const fn meta(self) -> u8

Metadata 0..=15.

pub const fn is_air(self) -> bool

true for air.

pub fn collision(self) -> Collision

Collision boxes, what else they depend on, and how vanilla places them in the world (Collision::world_box). Hot path: three table lookups.

pub fn selection(self) -> Selection

Crosshair ray-test data (oracle selection_boxes.jsonl.gz).

pub fn shape(self) -> &'static [Aabb]

The collision boxes from the table (for dependent shapes: the isolated / default shape).

pub fn fluid(self) -> Option<Fluid>

Fluid in this state (water / lava blocks; level = meta).

impl Ord for BlockState

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
