Struct Selection 

pub struct Selection {
    pub bounds: Aabb,
    pub dependency: ShapeDependency,
    pub multi_pass_ray: bool,
    pub can_collide: bool,
    pub can_collide_liquid: bool,
    pub has_collision_box: bool,
}

What the 1.8.9 crosshair ray test (Block.rayTrace via World.rayTrace) sees of a block state.

Fields

bounds: Aabb

Bounds after setBoundingBox(world, pos) with all neighbours air (block-local). For neighbour-dependent blocks this is the isolated shape, see dependency.

dependency: ShapeDependency

Same classes as the collision dependency (fences, panes, walls, doors, chests, stairs).

multi_pass_ray: bool

Stairs: vanilla’s ray test runs 8 passes over half-cube sub-boxes instead of using bounds.

can_collide: bool

Block.canCollide(state, false): rays skip the block when false (air, fire, fluids, …).

can_collide_liquid: bool

Block.canCollide(state, true) (ray tests that stop at fluids).

has_collision_box: bool

The block has a collision box (for ignoreBlockWithoutBoundingBox ray tests).
