Enum heron_core::CollisionEvent

pub enum CollisionEvent {
    Started(Entity, Entity),
    Stopped(Entity, Entity),
}

An event fired when the collision state between two entities changed

Example

fn detect_collisions(mut reader: Local<EventReader<CollisionEvent>>, events: Res<Events<CollisionEvent>>) {
    for event in reader.iter(&events) {
        match event {
            CollisionEvent::Started(entity1, entity2) => println!("Entity {:?} and {:?} started to collide", entity1, entity2),
            CollisionEvent::Stopped(entity1, entity2) => println!("Entity {:?} and {:?} stopped to collide", entity1, entity2),
        }   
    }   
}

Variants

Started(Entity, Entity)

The two entities started to collide

Stopped(Entity, Entity)

The two entities no longer collide
