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)
The two entities no longer collide
Implementations
sourceimpl CollisionEvent
impl CollisionEvent
sourcepub fn is_started(&self) -> bool
pub fn is_started(&self) -> bool
Returns true if the event represent the “start” of a collision
sourcepub fn is_stopped(&self) -> bool
pub fn is_stopped(&self) -> bool
Returns true if the event represent the “end” of a collision
sourcepub fn data(self) -> (CollisionData, CollisionData)
pub fn data(self) -> (CollisionData, CollisionData)
Returns the data for the two entities that collided
sourcepub fn collision_shape_entities(&self) -> (Entity, Entity)
pub fn collision_shape_entities(&self) -> (Entity, Entity)
Returns the entities containing the CollisionShape
involved in the collision
sourcepub fn rigid_body_entities(&self) -> (Entity, Entity)
pub fn rigid_body_entities(&self) -> (Entity, Entity)
Returns the entities containing the RigidBody
involved in the collision
sourcepub fn collision_layers(&self) -> (CollisionLayers, CollisionLayers)
pub fn collision_layers(&self) -> (CollisionLayers, CollisionLayers)
Returns the two CollisionLayers
involved in the collision
