Struct LightSectionRange 

pub struct LightSectionRange {
    min_section_y: i32,
    section_count: i32,
}

Inclusive/exclusive vertical range of light sections for a level.

Vanilla’s LevelLightEngine exposes this as getMinLightSection(), getMaxLightSection(), and getLightSectionCount(). The range is padded by one section below and one section above the real chunk sections.

Fields

min_section_y: i32

section_count: i32

Implementations

impl LightSectionRange

pub const fn from_world_height( min_y: i32, height: i32, ) -> Result<Self, LightSectionRangeError>

Creates the vanilla padded light-section range for a world height.

pub const fn min_section_y(self) -> i32

Returns the first light section Y coordinate.

pub const fn max_section_y_exclusive(self) -> i32

Returns the section Y coordinate one past the last light section.

pub const fn section_count(self) -> usize

Returns the number of light sections in this range.

pub const fn min_chunk_section_y(self) -> i32

Returns the first real chunk section Y coordinate.

pub const fn max_chunk_section_y_exclusive(self) -> i32

Returns the real chunk section Y coordinate one past the last section.

pub const fn chunk_section_count(self) -> usize

Returns the number of real chunk sections inside this light range.

pub const fn section_y(self, section_index: usize) -> Option<i32>

Converts a packet light-section index to a section Y coordinate.

pub const fn section_index(self, section_y: i32) -> Option<usize>

Converts a section Y coordinate to a packet light-section index.

pub const fn chunk_section_y(self, section_index: usize) -> Option<i32>

Converts a real chunk-section index to a section Y coordinate.

pub const fn chunk_section_index(self, section_y: i32) -> Option<usize>

Converts a real chunk section Y coordinate to an emptiness-map index.
