Struct bevy::prelude::BorderRadius

pub struct BorderRadius {
    pub top_left: Val,
    pub top_right: Val,
    pub bottom_left: Val,
    pub bottom_right: Val,
}

Used to add rounded corners to a UI node. You can set a UI node to have uniformly rounded corners or specify different radii for each corner. If a given radius exceeds half the length of the smallest dimension between the node’s height or width, the radius will calculated as half the smallest dimension.

Elliptical nodes are not supported yet. Percentage values are based on the node’s smallest dimension, either width or height.

Example

fn setup_ui(mut commands: Commands) {
    commands.spawn((
        NodeBundle {
            style: Style {
                width: Val::Px(100.),
                height: Val::Px(100.),
                border: UiRect::all(Val::Px(2.)),
                ..Default::default()
            },
            background_color: BLUE.into(),
            border_radius: BorderRadius::new(
                // top left
                Val::Px(10.),
                // top right
                Val::Px(20.),
                // bottom right
                Val::Px(30.),
                // bottom left
                Val::Px(40.),
            ),
            ..Default::default()
        },
    ));
