PropagateEntityTrigger

Struct PropagateEntityTrigger 

Source
pub struct PropagateEntityTrigger<const AUTO_PROPAGATE: bool, E, T>
where E: EntityEvent, T: Traversal<E>,
{ pub original_event_target: Entity, pub propagate: bool, /* private fields */ }
Expand description

An EntityEvent Trigger that behaves like EntityTrigger, but “propagates” the event using an Entity Traversal. At each step in the propagation, the EntityTrigger logic will be run, until PropagateEntityTrigger::propagate is false, or there are no entities left to traverse.

This is used by the EntityEvent derive when #[entity_event(propagate)] is enabled. It is usable by every EntityEvent type.

If AUTO_PROPAGATE is true, PropagateEntityTrigger::propagate will default to true.

Fields§

§original_event_target: Entity

The original Entity the Event was first triggered for.

§propagate: bool

Whether or not to continue propagating using the T Traversal. If this is false, The Traversal will stop on the current entity.
