Struct amethyst::ecs::storage::TrackChannels

pub struct TrackChannels {
    pub modify: EventChannel<ModifiedFlag>,
    pub insert: EventChannel<InsertedFlag>,
    pub remove: EventChannel<RemovedFlag>,
}

Fields

modify: EventChannel<ModifiedFlag>

Note: This does not include insertions, only when a component is changed after it has been added to an entity.

insert: EventChannel<InsertedFlag>

Insertions event channel.

Note: Insertion events only occur when something inserts a component without there being a pre-existing component. If there is a pre-existing component for an entity then it will fire a modification event.
