Struct ExplosionExposureRaycast 

pub(crate) struct ExplosionExposureRaycast<'world> {
    world: &'world World,
    collision_context: BlockCollisionContext,
    full_chunks: LocalFullChunkHolderCache,
    entries: [ExplosionExposureCacheEntry; 256],
    clear_grid: ExplosionExposureClearGrid,
    generation: u32,
}

Bounded cache for vanilla explosion exposure rays.

Missing chunks are never cached, allowing asynchronous Full publication to become visible while the synchronous gameplay callback is running. Dynamic and non-Vanilla collision shapes are resolved on every visit so live block entities and plugin callbacks retain their normal query semantics. Reuse across entities is only valid when the caller can prove that the intervening entity callbacks cannot mutate blocks; callers must clear the cache before invoking any other entity implementation.

Fields

world: &'world World

collision_context: BlockCollisionContext

Implementations

impl<'world> ExplosionExposureRaycast<'world>

pub(crate) const fn new( world: &'world World, collision_context: BlockCollisionContext, ) -> Self

pub(crate) fn configure_clear_grid(&mut self, min: BlockPos, max: BlockPos)

Configures a bounded, explosion-local cache of statically clear positions.

Bounds that exceed the inline capacity disable the optimization and retain the exact compatibility path.

pub(crate) fn clear(&mut self)

Drops every retained static collision result.

pub(crate) const fn set_collision_context( &mut self, collision_context: BlockCollisionContext, )

Selects the entity collision context used by subsequent exposure rays.

pub(crate) fn stable_air_box_is_clear( &mut self, bounds: BlockRegionBounds, ) -> bool

Proves that an inclusive block box contains only immutable Vanilla air.

fn retain_cache_after_collision_query(&mut self, block: BlockRef) -> bool

Keeps cached shapes only across Steel-owned Vanilla collision behavior calls.

Plugin behavior may mutate another block while answering a shape query. Clearing after its callback makes the next Vanilla DDA visit read the same live state Vanilla would observe.

pub(crate) fn is_path_clear(&mut self, from: DVec3, to: DVec3) -> bool

Returns whether a collider-only, fluid-free exposure ray misses every block.

fn block_intersects_ray( &mut self, pos: BlockPos, from: DVec3, to: DVec3, ) -> bool

fn block_intersects_ray_exact( &mut self, pos: BlockPos, from: DVec3, to: DVec3, unresolved_grid_index: Option<usize>, ) -> bool

fn static_collision_intersects( collision: OffsetVoxelShape, pos: BlockPos, from: DVec3, to: DVec3, ) -> bool
