Trait bevy::render::extract_component::ExtractComponent

pub trait ExtractComponent: Component {
    type Query: WorldQuery + ReadOnlyWorldQuery;
    type Filter: WorldQuery + ReadOnlyWorldQuery;

    fn extract_component(item: <Self::Query as WorldQuery>::Item<'_>) -> Self;
}

Describes how a component gets extracted for rendering.

Therefore the component is transferred from the “app world” into the “render world” in the RenderStage::Extract step.

Required Associated Types

type Query: WorldQuery + ReadOnlyWorldQuery

ECS WorldQuery to fetch the components to extract.

type Filter: WorldQuery + ReadOnlyWorldQuery

Filters the entities with additional constraints.

Required Methods

fn extract_component(item: <Self::Query as WorldQuery>::Item<'_>) -> Self

Defines how the component is transferred into the “render world”.
