pub struct Events<T> { /* private fields */ }Expand description
Gizmo ECS Event System — Double-buffered olay kuyruğu.
Her frame’de update() çağrıldığında, önceki frame’in eventleri atılır ve
mevcut frame’in eventleri “önceki” konumuna taşınır. Bu sayede:
- Yazarlar (
send) her zamancurrentbuffer’a yazar. - Okuyucular (
iter) her zamanpreviousbuffer’dan okur (non-destructive). - Birden fazla sistem aynı eventleri bağımsız olarak okuyabilir.
§Kullanım
ⓘ
// Kayıt (App seviyesinde):
app.add_event::<CollisionEvent>();
// Olay gönderme (herhangi bir sistem):
world.get_resource_mut::<Events<CollisionEvent>>().unwrap().send(CollisionEvent(..));
// Olay okuma (herhangi bir sistem, non-destructive):
let events = world.get_resource::<Events<CollisionEvent>>().unwrap();
for event in events.iter() {
tracing::info!("Çarpışma oldu: {:?}", event);
}Implementations§
Source§impl<T> Events<T>
impl<T> Events<T>
pub fn new() -> Events<T>
Sourcepub fn update(&mut self)
pub fn update(&mut self)
Frame sonu: önceki frame’in eventlerini temizler, mevcut frame’i önceki konuma taşır.
Bu metot her frame sonunda bir kez çağrılmalıdır — App::add_event() bunu
otomatik olarak yapar.
