Struct EndIslands 

pub struct EndIslands {
    island_noise: SimplexNoise,
}

End islands density function.

Unlike overworld/nether density functions which are transpiled into native Rust, this is used directly at runtime because it’s a self-contained leaf algorithm (simplex noise + neighbor loop) with no density function tree to transpile.

Fields

island_noise: SimplexNoise

Implementations

impl EndIslands

pub fn new(seed: u64) -> EndIslands

Create a new EndIslands with the given world seed.

Matches vanilla’s RandomState.NoiseWiringHelper.wrapNew() which creates EndIslandDensityFunction(worldSeed), NOT seed 0. The JSON codec defaults to seed 0, but RandomState replaces it with the world seed.

pub fn sample(&self, block_x: f64, _block_y: f64, block_z: f64) -> f64

Sample the density value at block coordinates.

Converts block coordinates to section coordinates internally (divides by 8).

Trait Implementations

impl Clone for EndIslands

fn clone(&self) -> EndIslands

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EndIslands

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

Formats the value using the given formatter.
