How to change to an animation from a different aseprite file?

[echoptic]

I have these 2 aseprite files imported:

mod sprites {
    use bevy_aseprite::aseprite;

    aseprite!(pub KnightIdle, "Heroes/Knight/Idle/Idle.aseprite");
    aseprite!(pub KnightRun, "Heroes/Knight/Run/Run.aseprite");
}

And I tried changing the animation in a system like this:

fn change_animation(
    mut query: Query<&mut Handle<Aseprite>, With<Knight>>,
    keyboard_input: Res<Input<KeyCode>>,
    asset_server: Res<AssetServer>,
) {
    for mut aseprite in &mut query {
        if keyboard_input.just_pressed(KeyCode::Space) {
            *aseprite = asset_server.load(sprites::KnightRun::PATH);
        }
    }
}

but when the animation changes i get a crash:

thread '<unnamed>' panicked
Sprite index 4 does not exist for texture atlas handle AssetId<bevy_sprite::texture_atlas::TextureAtlas>{ index: 0, generation: 1}.
Encountered a panic in system `bevy_sprite::render::extract_sprites`!

Out of curiosity, why did you separate your animations into different files instead of tagging them as certain animations in Aseprite?

It seems like it would be easier to tag them instead of changing files.

Just a guess, but if you're packing textures, you might keep each individual animation in its own atlas/sheet. Helps with batch rendering if they're all the same file. If it's detailed animation they might not all fit in the same file.

Im running into this issue and would like to know a solution as well. I have a large player animation file with many tags, but i need a different aseprite file per direction (top down game). for example player_up.aseprite, vs 'player_down.aseprite. Changing between these does not work, and seems to give an error that says Aseprite info is None`, which doesnt make sense...

Adding all of the animations into. one giga large file is possible, but not really that ideal
