# Objective Add support for multiple box shadows on a single `Node`. ## Solution * Rename `BoxShadow` to `ShadowStyle` and remove its `Component` derive. * Create a new `BoxShadow` component that newtypes a `Vec<ShadowStyle>`. * Add a `new` constructor method to `BoxShadow` for single shadows. * Change `extract_shadows` to iterate through a list of shadows per node. Render order is determined implicitly from the order of the shadows stored in the `BoxShadow` component, back-to-front. Might be more efficient to use a `SmallVec<[ShadowStyle; 1]>` for the list of shadows but not sure if the extra friction is worth it. ## Testing Added a node with four differently coloured shadows to the `box_shadow` example. --- ## Showcase ``` cargo run --example box_shadow ``` <img width="460" alt="four-shadow" src="https://github.com/user-attachments/assets/2f728c47-33b4-42e1-96ba-28a774b94b24"> ## Migration Guide Bevy UI now supports multiple shadows per node. A new struct `ShadowStyle` is used to set the style for each shadow. And the `BoxShadow` component is changed to a tuple struct wrapping a vector containing a list of `ShadowStyle`s. To spawn a node with a single shadow you can use the `new` constructor function: ```rust commands.spawn(( Node::default(), BoxShadow::new( Color::BLACK.with_alpha(0.8), Val::Percent(offset.x), Val::Percent(offset.y), Val::Percent(spread), Val::Px(blur), ) )); ``` --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> |
