Enum heron_core::CollisionEvent

source · [−]

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

Expand description

An event fired when the collision state between two entities changed

Example

fn detect_collisions(mut events: EventReader<CollisionEvent>) {
    for event in events.iter() {
        match event {
            CollisionEvent::Started(data1, data2) => {
                println!("Entity {:?} and {:?} started to collide", data1.rigid_body_entity(), data2.rigid_body_entity())
            }
            CollisionEvent::Stopped(data1, data2) => {
                println!("Entity {:?} and {:?} stopped to collide", data1.rigid_body_entity(), data2.rigid_body_entity())
            }
        }
    }
}

Variants

`Started(CollisionData, CollisionData)`

The two entities started to collide

`Stopped(CollisionData, CollisionData)`
