Several different heightmaps corresponding to 256 values compacted at 9 bits per value (lowest being 0, highest being 384, both values inclusive).

Fields

motion_blocking: Option<HeightMap>

Stores the Y-level of the highest block whose material blocks motion (i.e. has a collision box) or blocks that contains a fluid (water, lava, or waterlogging blocks).

motion_blocking_no_leaves: Option<HeightMap>

Stores the Y-level of the highest block whose material blocks motion (i.e. has a collision box), or blocks that contains a fluid (water, lava, or waterlogging blocks), except various leaves. Used only on the server side.

ocean_floor: Option<HeightMap>

Stores the Y-level of the highest block whose material blocks motion (i.e. has a collision box). One exception is carpets, which are considered to not have a collision box to heightmaps. Used only on the server side.

ocean_floor_wg: Option<HeightMap>

Stores the Y-level of the highest block whose material blocks motion (i.e. has a collision box). Used only during world generation, and automatically deleted after carvers are generated.

world_surface: Option<HeightMap>

Stores the Y-level of the highest non-air (all types of air) block.

world_surface_wg: Option<HeightMap>

Stores the Y-level of the highest non-air (all types of air) block. Used only during world generation, and automatically deleted after carvers are generated.

Trait Implementations

impl Clone for HeightMaps

fn clone(&self) -> HeightMaps

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HeightMaps

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HeightMaps

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for HeightMaps

fn eq(&self, other: &HeightMaps) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
