🍸 Moonshine Core

Unconventional cocktail of libraries to make ECS-driven development easier and safer in Bevy.

See individual crates for detailed documentation and examples.

🍎 Moonshine Kind

Type safety solution for Bevy entities:

use bevy::prelude::*;
use moonshine_core::prelude::*;

#[derive(Component)]
struct Fruit;

#[derive(Component)]
struct FruitBasket {
    fruits: Vec<Instance<Fruit>>
}

🌴 Moonshine Object

Ergonomic wrapper for managing complex enttiy hierarchies:

use bevy::prelude::*;
use moonshine_core::prelude::*;

#[derive(Component)]
struct Bird;

#[derive(Component)]
struct Flying;

fn setup_bird(birds: Objects<Bird, Added<Flying>>, mut commands: Commands) {
    for bird in birds.iter() {
        if let Some(wings) = bird.find_by_path("./Wings") {
            for wing in wings.children() {
                // TODO: Flap! Flap!
            }
        }
    }
}

💾 Moonshine Save

Save/Load framework for managing persistent game state:

use bevy::prelude::*;
use moonshine_core::prelude::*;

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_plugins((SavePlugin, LoadPlugin))
        .add_systems(PreUpdate, save_default().into_file("world.ron").run_if(should_save))
        .add_systems(PreUpdate, load_from_file("world.ron").run_if(should_load))
        .run();
}

fn should_save(key: Res<ButtonInput<KeyCode>>) -> bool {
    key.just_pressed(KeyCode::KeyS)
}

fn should_load(key: Res<ButtonInput<KeyCode>>) -> bool {
    key.just_pressed(KeyCode::KeyL)
}
