pub struct EntityComponentsTrigger<'a> {
pub components: &'a [ComponentId],
}Expand description
An EntityEvent Trigger that, in addition to behaving like a normal EntityTrigger, also runs observers
that watch for components that match the slice of ComponentIds referenced in EntityComponentsTrigger. This includes
both global observers of those components and “entity scoped” observers that watch the EntityEvent::event_target.
This is used by Bevy’s built-in lifecycle events.
Fields§
§components: &'a [ComponentId]All of the components whose observers were triggered together for the target entity. For example,
if components A and B are added together, producing the Add event, this will
contain the ComponentId for both A and B.
