pub trait Component: 'static + Send + Sync {
type Storage: ComponentStorage;
}Expand description
A component is data associated with an Entity. Each entity can have
multiple different types of components, but only one of them per type.
Any type that is Send + Sync + 'static can implement Component using #[derive(Component)].
In order to use foreign types as components, wrap them using a newtype pattern.
use std::time::Duration;
#[derive(Component)]
struct Cooldown(Duration);Components are added with new entities using Commands::spawn,
or to existing entities with EntityCommands::insert,
or their World equivalents.
Components can be accessed in systems by using a Query
as one of the arguments.
Components can be grouped together into a Bundle.
