bevy_channel_trigger

Send events via a channel from anywhere (eg. web-dom, c-ffi) to Bevy Observers. Inspired by bevy_crossbeam_event but using flume instead of crossbeam as the underlying efficient unbounded channel and delivering the events via Bevy Observers instead of EventReader. Furthermore we lint to be guaranteed panic free.

example

#[derive(Event)]
struct MyEvent(i32);

fn main() {
    use bevy_channel_trigger::ChannelTriggerApp;

    let mut app = App::new();
    app.add_plugins(MinimalPlugins);

    // create channel
    let sender = app.add_channel_trigger::<MyEvent>();

    // use sender from anywhere:
    thread::spawn(move || {
        let mut counter = 1;
        loop {
            // send events back to bevy
            sender.send(MyEvent(counter));
            thread::sleep(Duration::from_secs(1));
            counter += 1;
        }
    });

    // register an observer to receive the events sent via `sender`
    app.observe(on_event);

    app.run();
}

// regular bevy observer to handle these events coming into the bevy world
fn on_event(trigger: Trigger<MyEvent>) {
    let event = trigger.event();
    println!("trigger with: {}", event.0);
}
