# Objective We switch back and forwards between logical and physical coordinates all over the place. Systems have to query for cameras and the UiScale when they shouldn't need to. It's confusing and fragile and new scale factor bugs get found constantly. ## Solution * Use physical coordinates whereever possible in `bevy_ui`. * Store physical coords in `ComputedNode` and tear out all the unneeded scale factor calculations and queries. * Add an `inverse_scale_factor` field to `ComputedNode` and set nodes changed when their scale factor changes. ## Migration Guide `ComputedNode`'s fields and methods now use physical coordinates. `ComputedNode` has a new field `inverse_scale_factor`. Multiplying the physical coordinates by the `inverse_scale_factor` will give the logical values. --------- Co-authored-by: atlv <email@atlasdostal.com> |
