Enum PartialSurfaceCondition 

pub enum PartialSurfaceCondition {
    AbovePreliminarySurface,
    BiomeSet(usize),
    VerticalGradient {
        true_at_and_below: i32,
        false_at_and_above: i32,
    },
    YAtLeast(i32),
    Not(&'static Self),
    Opaque,
}

A surface condition reduced to what is decidable below the preliminary surface.

Variants

AbovePreliminarySurface

block_y >= min_surface_level: false for every block resolved here.

BiomeSet(usize)

Membership in the rule’s biome_is set at this index.

VerticalGradient

vertical_gradient: true at and below the first Y, false at and above the second, a positional random draw in between.

Fields

true_at_and_below: i32

Highest Y where the condition always holds.

false_at_and_above: i32

Lowest Y where the condition never holds.

YAtLeast(i32)

y_above without stone depth or surface-depth scaling.

Not(&'static Self)

Logical negation.

Opaque

Depends on more than Y and biome (noise, stone depth, water, …).

Implementations

impl PartialSurfaceCondition

pub fn resolve(&self, block_y: i32, biome_set_mask: u64) -> Option<bool>

Some when the condition is decided by block_y and the biome sets.

Trait Implementations

impl Debug for PartialSurfaceCondition

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

Formats the value using the given formatter.
