Trait for providing noise values and clay band data to surface rules.

Implemented by SurfaceSystem in steel-core. The transpiled code calls these methods through the SurfaceRuleContext.system field.

Required Methods

fn condition_noise(&self, noise_index: usize, x: i32, z: i32) -> f64

Sample a surface condition noise at (x, z). The noise is identified by its index in the dimension’s surface_noise_ids() list.

fn condition_noise_3d(&self, noise_index: usize, x: i32, y: i32, z: i32) -> f64

Sample a surface condition noise at (x, y, z). The noise is identified by its index in the dimension’s surface_noise_ids() list.

fn get_band(&self, x: i32, y: i32, z: i32) -> BlockStateId

Get the badlands clay band block at position (x, y, z).

fn cold_enough_to_snow( &self, biome_id: u16, block_x: i32, block_y: i32, block_z: i32, ) -> bool

Evaluates whether the biome temperature is cold enough for snow.

fn vertical_gradient( &self, gradient_index: usize, block_x: i32, block_y: i32, block_z: i32, true_at_and_below: i32, false_at_and_above: i32, ) -> bool

Evaluate a vertical gradient condition using positional random.

Returns true if the random value at (block_x, block_y, block_z) falls within the gradient between true_at_and_below and false_at_and_above.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
