Commands Send Event

An extension trait for Commands that allows you to send events from a system without having to retrieve a typed EventWriter SystemParam.

• version 0.9 supports Bevy 0.9
• version 0.5 supports Bevy 0.8
• version 0.3 & 0.4 support Bevy 0.7
• versions <0.3 support Bevy 0.6

Limitations

• Events won't be dispatched immediately, but at the next Stage boundary when the queued commands are applied to the World.

#

Usage

Add to your project with the command cargo add commands_send_event

or add directly add the dependency to your Cargo.toml toml [dependencies.commands_send_event] version = "0.6"

then the send_event method is available on Commands:

```rust use commandssendevent::CommandsSendEvent;

[derive(Component)]

struct MyEventA(String);

[derive(Component)]

struct MyEventB(i32);

fn sender( mut commands: Commands ) { commands.sendevent(MyEventA("Hello, World")); commands.sendevent(MyEventB(42)); } The `/examples` folder has two examples you can run with: cargo run --example basic_usage cargo run --example schedule ```

AnyEventWriter is a facade over Commands that implements SystemParam.

#

Note

This crate is a bit redundant now since Bevy 0.8 as sending events using World is very easy. With commands.add you can queue a closure to dispatch an event like so: rust commands.add(|world: &mut World| world.send_event(MyEvent) );
