}

Seeded grass patch split into transient mesh chunks for frustum culling. Wind is animated by the grass shader; geometry is rebuilt when parameters change.

Fields

count: i32

Blades in the whole patch.

width: f32

Patch size in metres, centred on the entity.

depth: f32

Patch depth in metres along the local Z axis.

blade_height: f32

Mean blade height in metres.

height_variation: f32

Relative randomized variation of blade height.

blade_width: f32

Blade base width in metres.

lean: f32

Resting lean of the blades.

seed: i32

Deterministic patch seed; identical parameters produce identical blades.

base_color: [f32; 4]

RGBA tint at the blade base.

tip_color: [f32; 4]

RGBA tint at the blade tip.

wind_strength: f32

Shader wind displacement multiplier.

wind_speed: f32

Shader wind animation speed multiplier.

chunk_size: f32

Chunk edge in metres: smaller chunks cull better, larger ones need fewer draw calls.

fade_start: f32

Distance where blades start thinning out, and where the grass is gone.

fade_end: f32

World-space distance where all grass blades have faded out.

patchiness: f32

0..1: patchy dry / lush colour variation across the meadow.

round: bool

Fill an ellipse inside width x depth instead of the whole rectangle (soft, thinning edge).

flowers: f32

Share of blades that carry a small wild flower, 0..0.3.

Trait Implementations

impl Clone for Grass

fn clone(&self) -> Grass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for Grass

const NAME: &'static str = "Grass"

Stable, globally unique name; keep it identical in the host and script library.

const KEY: u64 = _

Storage key derived from [Self::NAME]. Normally should not be overridden.

impl Component for Grass

fn fields(&mut self) -> Vec<Field<'_>>

Mutable field descriptors used by the Inspector and script property serialization.

const REMOVABLE: bool = true

Whether the user may remove it in the inspector.

impl Default for Grass

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Grass

where Grass: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Grass

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
