# Objective Allow users to enable or disable layout rounding for specific UI nodes and their descendants. Fixes #16731 ## Solution New component `LayoutConfig` that can be added to any UiNode entity. Setting the `use_rounding` field of `LayoutConfig` determines if the Node and its descendants should be given rounded or unrounded coordinates. ## Testing Not tested this extensively but it seems to work and it's not very complicated. This really basic test app returns fractional coords: ```rust use bevy::prelude::*; fn main() { App::new() .add_plugins(DefaultPlugins) .add_systems(Startup, setup) .add_systems(Update, report) .run(); } fn setup(mut commands: Commands) { commands.spawn(Camera2d); commands.spawn(( Node { left: Val::Px(0.1), width: Val::Px(100.1), height: Val::Px(100.1), ..Default::default() }, LayoutConfig { use_rounding: false }, )); } fn report(node: Query<(Ref<ComputedNode>, &GlobalTransform)>) { for (c, g) in node.iter() { if c.is_changed() { println!("{:#?}", c); println!("position = {:?}", g.to_scale_rotation_translation().2); } } } ``` --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> Co-authored-by: UkoeHB <37489173+UkoeHB@users.noreply.github.com> |
