Bevy Aseprite Ultra

The ultimate bevy aseprite plugin. This plugin allows you to import aseprite files into bevy, with 100% unbreakable hot reloading. You can also import static sprites from an aseprite atlas type file using slices with functional pivot offsets!

Bevy Version	Plugin Version
0.15	0.4.1
0.14	0.2.4
0.13	0.1.0

Supported aseprite features

• Animations
• Tags
• Frame duration, repeat, and animation direction
• Layer visibility
• Blend modes
• Static slices and pivot offsets

Features in bevy

• Hot reload anything, anytime, anywhere!
• Full control over animations using Components.
• One shot animations and events when they finish.
• Static sprites with slices. Use aseprite for all your icon and UI needs!

(hot reloading requires the file_watcher feature in bevy)

Embedding Assets

There is currently no asset preprocessor. If you do not want to ship raw aseprite files, use bevy_embedded_assets to embed your assets into the final binary.

Example

cargo run --example slices
cargo run --example animations
cargo run --example ui

// Load an animation from an aseprite file
fn spawn_demo_animation(mut cmd : Commands, server : Res<Assetserver>){
    cmd.spawn((
        AseSpriteAnimation {
            aseprite: server.load("player.aseprite"),
            animation: Animation::tag("walk-right")
                .with_repeat(AnimationRepeat::Count(1))
                .with_speed(2.)
                // Aseprite provides a repeat config per tag, which is beeing ignored on purpose.
                .with_repeat(AnimationRepeat::Count(42))
                // The direction is provided by the asperite config for the tag, but can be overwritten.
                .with_direction(AnimationDirection::PingPong)
                // you can also chain finite animations, loop animations will never finish
                .with_then("walk-left", AnimationRepeat::Count(4))
                .with_then("walk-up", AnimationRepeat::Loop),
        },
        Sprite {
            // under the hood its just sprites.
            // only the image and atlas is touched.
            // this works
            flip_x: true,
            ..default()
        },
    ));
}

// Load a static slice from an aseprite file
// create for any static atlas with marked regions aka slices.
fn spawn_demo_static_slice(mut cmd : Commands, server : Res<Assetserver>){
    cmd.spawn((
        AseSpriteSlice {
            name: "ghost_red".into(),
            aseprite: server.load("ball.aseprite"),
        },
    ));
}

// animation events
// this is useful for one shot animations like explosions
fn despawn_on_finish(mut events: EventReader<AnimationEvents>, mut cmd : Commands){
    for event in events.read() {
        match event {
            AnimationEvents::Finished(entity) => cmd.entity(*entity).despawn_recursive(),
            // you can also listen for loop cycle repeats
            AnimationEvents::LoopCycleFinished(_entity) => (),
        };
    }
}

Bevy Ui

There is also an Ui Bundle for Bevy Ui Nodes!

// animations in bevy ui
cmd.spawn((
        Button,
        AseUiAnimation {
            aseprite: server.load("player.aseprite"),
            animation: Animation::tag("walk-right"),
        },
));

// slices in bevy ui
cmd.spawn((
        Node {
            width: Val::Px(100.),
            height: Val::Px(100.),
            border: UiRect::all(Val::Px(5.)),
            ..default()
        },
        AseUiSlice {
            name: "ghost_red".into(),
            aseprite: server.load("ghost_slices.aseprite"),
        },
));
