Enum heron::prelude::CollisionEvent [−][src]
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
Tuple Fields of Started
Stopped(CollisionData, CollisionData)
The two entities no longer collide
Tuple Fields of Stopped
Implementations
Returns true if the event represent the “start” of a collision
Returns true if the event represent the “end” of a collision
Returns the data for the two entities that collided
Returns the entities containing the CollisionShape
involved in the collision
Returns the entities containing the RigidBody
involved in the collision
Returns the two CollisionLayers
involved in the collision
