# Objective - Migrate UI bundles to required components, fixes #15889 ## Solution - deprecate `NodeBundle` in favor of `Node` - deprecate `ImageBundle` in favor of `UiImage` - deprecate `ButtonBundle` in favor of `Button` ## Testing CI. ## Migration Guide - Replace all uses of `NodeBundle` with `Node`. e.g. ```diff commands - .spawn(NodeBundle { - style: Style { + .spawn(( + Node::default(), + Style { width: Val::Percent(100.), align_items: AlignItems::Center, justify_content: JustifyContent::Center, ..default() }, - ..default() - }) + )) ``` - Replace all uses of `ButtonBundle` with `Button`. e.g. ```diff .spawn(( - ButtonBundle { - style: Style { - width: Val::Px(w), - height: Val::Px(h), - // horizontally center child text - justify_content: JustifyContent::Center, - // vertically center child text - align_items: AlignItems::Center, - margin: UiRect::all(Val::Px(20.0)), - ..default() - }, - image: image.clone().into(), + Button, + Style { + width: Val::Px(w), + height: Val::Px(h), + // horizontally center child text + justify_content: JustifyContent::Center, + // vertically center child text + align_items: AlignItems::Center, + margin: UiRect::all(Val::Px(20.0)), ..default() }, + UiImage::from(image.clone()), ImageScaleMode::Sliced(slicer.clone()), )) ``` - Replace all uses of `ImageBundle` with `UiImage`. e.g. ```diff - commands.spawn(ImageBundle { - image: UiImage { + commands.spawn(( + UiImage { texture: metering_mask, ..default() }, - style: Style { + Style { width: Val::Percent(100.0), height: Val::Percent(100.0), ..default() }, - ..default() - }); + )); ``` --------- Co-authored-by: Carter Anderson <mcanders1@gmail.com>
