bevy_crossbeam_event

Fire Bevy events from crossbeam channels.

Useful if you need to handle callbacks in 3rd party libraries etc. like steamworks-rs, or getting events out of tracing layers.

Usage

Add add events to your app using .add_crossbeam_event::<EventType>:

#[derive(Event, Clone, Debug)]
struct LobbyJoined(Lobby);

impl Plugin for MyPlugin {
    fn build(&self, app: &mut App) {
        app.add_crossbeam_event::<LobbyJoined>();
        app.add_startup_system(setup);
        app.add_system(handle_lobby_joined);
    }
}

Fire events by using Res<CrossbeamEventSender<EventType>> (which can be cloned and sent into callbacks):

fn setup(service: Res<ThirdPartyCode>, sender: Res<CrossbeamEventSender<LobbyJoined>>) {
    let sender = sender.clone();
    service.join_lobby(id, move |lobby| {
        sender.send(LobbyJoined(lobby));
    });
}

Handle the events just like normal Bevy events (which they are):

fn handle_lobby_joined(mut lobby_joined_events: EventReader<LobbyJoined>) {
    for lobby in lobby_joined_events.read() {
        info!("lobby joined: {lobby:?}");
    }
}
