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!

The plugin is currently being battle tested and is not released yet

I use it in my game, check it out on my blog

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!

(for hotreload to work, you must have the file_watcher cargo dependency for bevy installed)

Example

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

character animation by Benjamin

There are two main Bundles added by this plugin, AsepriteAnimationBundle and AsepriteSliceBundle.

use bevy::prelude::*;
use bevy_aseprite_ultra::prelude::*;

...

// Load the an animation from an aseprite file
fn spawn_demo_animation(mut cmd : Commands, server : Res<Assetserver>){
    cmd.spawn(AsepriteAnimationBundle {
        aseprite: server.load("player.aseprite"),
        transform: Transform::from_translation(Vec3::new(15., -20., 0.)),
        animation: Animation::default()
                .with_tag("walk-right")
                .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
                // after the animation is loaded.
                .with_direction(AnimationDirection::PingPong),
                // you can also chain finite animations, loop animations with never finish
                .with_then("walk-left", AnimationRepeat::Count(4))
                .with_then("walk-up", AnimationRepeat::Loop)
        // you can override the default sprite settings here
        sprite: Sprite {
            flip_x: true,
            ..default()
        },
        ..default()
    });
}

// Load a static slice from an aseprite file
fn spawn_demo_static_slice(mut cmd : Commands, server : Res<Assetserver>){
    cmd.spawn(AsepriteSliceBundle {
        slice: "ghost_blue".into(),
        // you can override the default sprite settings here
        // the `rect` will be overriden by the slice
        // if there is a pivot provided in the aseprite slice, the `anchor` will be overwritten
        // and changes the origin of rotation.
        sprite: Sprite {
            flip_x: true,
            ..default()
        },
        aseprite: server.load("ghost_slices.aseprite"),
        transform: Transform::from_translation(Vec3::new(32., 0., 0.)),
        ..default()
    });
}

// animation events - tell me when the animation is done
// this is useful for one shot animations like explosions
fn despawn_on_finish(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((
        ButtonBundle{
            // node config
            ..default()
        },
        AsepriteAnimationUiBundle{
            aseprite: server.load("yourfile.aseprite"),
            animation: Animation{
                tag : Some("idle".to_string()),
                ..default()
            },
            ..default()
        },
));

// slices in bevy ui
cmd.spawn((
        ImageBundle{
            // node config
            ..default()
        },
        AsepriteSliceUiBundle{
            aseprite: server.load("yourfile.aseprite"),
            slice: AsepriteSlice::from("your_slice"),
            ..default()
        },
));
