Description
What problem does this solve or what need does it fill?
I would like to be able to use something like SpriteSheetBundle but for the UI. I have my UI sprites in an atlas and it would be convenient to be able to use it and not have to export the individual images with ImageBundle
Describe the solution would you like?
To be able to use SpriteSheetBundle as a UI element - be able to style it and position it, etc.
Describe the alternative(s) you've considered?
Additional context
I did not know it is not possible and I was actually trying to do something like this:
let player_texture_handle = asset_server.load("heart.png");
let texture_atlas = TextureAtlas::from_grid(player_texture_handle, Vec2::new(16.0, 16.0), 2, 1);
let texture_atlas_handle = texture_atlases.add(texture_atlas);
commands.spawn(NodeBundle {
style: Style {
position_type: PositionType::Absolute,
justify_content: JustifyContent::Center,
align_items: AlignItems::FlexEnd,
..Default::default()
},
..Default::default()
})
.with_children(|parent| {
parent.spawn(SpriteSheetBundle {
texture_atlas: texture_atlas_handle,
transform: Transform::from_translation(Vec3::new(0.0, 0.0, 0.0)),
..Default::default()
});
});
And it did not work. I understand it is because I am mixing UI and non-UI elements but I think the error message should be more helpful, I was really struggling to understand what is wrong. The error I got:
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value'
So I think a bit nicer error message would be also welcome for every other beginner out there like I am :)
Thanks!
