Struct Light 

pub struct Light {
    pub light_type: LightType,
    pub enabled: bool,
}

A component that adds a light source to an entity.

This component works in conjunction with the entity’s GlobalTransform to determine the light’s world-space position and orientation.

Examples

use khora_data::ecs::components::Light;
use khora_core::renderer::light::{LightType, DirectionalLight};

// Create a sun light
let sun_light = Light {
    light_type: LightType::Directional(DirectionalLight::default()),
    enabled: true,
};

Fields

light_type: LightType

The type and properties of the light source.

enabled: bool

Whether the light is currently active.

Disabled lights are not extracted for rendering and have no performance impact on the scene.

Implementations

impl Light

pub fn new(light_type: LightType) -> Self

Creates a new enabled light with the given type.

pub fn directional() -> Self

Creates a new directional light (sun-like).

pub fn point() -> Self

Creates a new point light.

pub fn spot() -> Self

Creates a new spot light.

Trait Implementations

impl Clone for Light

fn clone(&self) -> Light

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for Light

fn make_column() -> Box<dyn AnyVec>

where Self: Sized,

Creates this component’s empty storage column. Default: an AoS Vec<Self>.

fn push_into_column(self, column: &mut dyn AnyVec)

where Self: Sized,

Appends self as a new row into its column.

fn copy_row_between(src: &dyn AnyVec, src_row: usize, dst: &mut dyn AnyVec)

where Self: Sized,

Clones row src_row from src into dst (used when an entity migrates between pages on a structural change). Both columns are this component’s column type.

fn clone_from_column(column: &dyn AnyVec, row: usize) -> Self

where Self: Sized,

Reads row row of column as an owned value — the uniform by-value access path that works for both AoS (clone the &T) and field-SoA (gather the fields) layouts. Used by World::clone_component, the Soa<T> query, and the serialization recipe.

fn set_in_column(self, column: &mut dyn AnyVec, row: usize)

where Self: Sized,

Overwrites row row of column with self — the uniform by-value write path for both layouts (AoS assigns the slot; field-SoA scatters into the lanes). Used by World::set_component.

impl Debug for Light

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

Formats the value using the given formatter.

impl Default for Light

fn default() -> Self

Returns the “default value” for a type.
