Aseprite plugin for Bevy

![latest] ![doc]

A plugin for using Aseprite animations in Bevy.

The AsepriteBundle is composed of the same fields as the SpriteSheetBundle but with two extra components, Handle<Aseprite> and AsepriteAnimation.

Example

See examples/aseprite.rs for a complete example, you can run it with:

ignore cargo run --example aseprite

Usage

Basic usage is as follows:

```rust,ignore fn loadassets(assetserver: Res, mut asepritehandles: ResMut) { let player: Handle = assetserver.load("player.ase"); aseprite_handles.push(player); }

fn setup( mut commands: Commands, asepritehandles: Res, aseprites: Res>, ) { let asepritehandle = &asepritehandles[0]; let aseprite = aseprites.get(asepritehandle).unwrap(); let animation = AsepriteAnimation::new(aseprite.info(), "idle");

commands
    .spawn(Player)
    .insert(AsepriteBundle {
        texture_atlas: aseprite.atlas().clone_weak(),
        sprite: TextureAtlasSprite::new(animation.current_frame()),
        aseprite: aseprite_handle.clone_weak(),
        animation,
        ..default()
    });

}

[derive(Resource, Deref, DerefMut, Default)]

struct AsepriteHandles(Vec>); ```

The component AsepriteAnimation also exposes methods to get information such as the current animation frame (within the tag or not), its duration, or the number of remaining frames. This can be useful to transition states at the end of an animation:

rust,ignore fn transition_player( time: Res<Time>, player_q: Query<(&PlayerState, &Handle<Aseprite>, &AsepriteAnimation), With<Player>>, aseprites: Res<Assets<Aseprite>>, mut ev_player_changed: EventWriter<PlayerChanged>, ) { let (&player_state, handle, anim) = player_q.single(); let aseprite = aseprites.get(handle).unwrap(); match player_state { PlayerState::Attack => { let remaining_frames = anim.remaining_tag_frames(aseprite.info()).unwrap(); let frame_finished = anim.frame_finished(time.delta()); if remaining_frames == 0 && frame_finished { ev_player_changed.send(PlayerChanged::default().new_state(PlayerState::Stand)); } } _ => (), } }
