# bevy_spawn_observer

[![Crates.io](https://img.shields.io/crates/v/bevy_spawn_observer.svg)](https://crates.io/crates/bevy_spawn_observer)
[![Docs](https://docs.rs/bevy_spawn_observer/badge.svg)](https://docs.rs/bevy_spawn_observer/latest/bevy_spawn_observer/)
[![License](https://img.shields.io/badge/license-MIT%2FApache-blue.svg)](https://github.com/benfrankel/bevy_spawn_observer)

This crate provides [`SpawnObserver`](https://docs.rs/bevy_spawn_observer/latest/bevy_spawn_observer/struct.SpawnObserver.html),
a custom [`SpawnableList`](https://docs.rs/bevy/latest/bevy/ecs/spawn/trait.SpawnableList.html)
enabling you to add observers to your bundles.

```rust
use bevy::{ecs::spawn::SpawnWith, prelude::*};
use bevy_spawn_observer::SpawnObserver;

// With `bevy_spawn_observer`:
fn button_new() -> impl Bundle {
    (
        Button,
        Children::spawn(SpawnObserver::new(|_: Trigger<Pointer<Click>>| {
            info!("You clicked me!");
        })),
    )
}

// Without `bevy_spawn_observer`:
fn button_old() -> impl Bundle {
    (
        Node::default(),
        Children::spawn(SpawnWith(|parent: &mut ChildSpawner| {
            parent.spawn(Button).observe(|_: Trigger<Pointer<Click>>| {
                info!("You clicked me!");
            });
        })),
    )
}
```
