bevy_spawn_fn

Awesome spawning experience for bevy.

Getting Started

Annotate your system with #[spawner_system], then use the spawn! macro.

#[spawner_system]
pub fn particle_emitter(emitter: Res<ParticleEmitter>) {
    if emitter.should_spawn() {
        spawn! {
            ParticleBundle {
                color: Color::Green,
                size: 10.0,
                texture: @load "images/my_image.png"
            }
        }
    }
}

If the function not a system, use the #[spawner_fn] macro, which takes less liberty in rewriting the function.

The `spawn!` macro

spawn! spawns a IntoSpawnable and return an Entity.

The macro uses the infer_construct! macro from the default_constructor crate under the hood, which uses the InferInto trait for conversion.

Additionally effect @load can be used to load Handle<T> from a string path and @asset can be used to convert impl Into<T> to Handle<T> via AssetServer.

The `Spawnable` Trait

Spawnable is a superset of Bundle that can be implemented to spawn heterogenous bundles and children.

IntoSpawnable is free ergonomics on top of Spawnable!
