When to Load

HUDs, menus, shops, dialogs, world UI, and layout bugs on phone, tablet, desktop or TV.

Quick Reference

  • Mobile first: design on the smallest landscape phone with touch controls, then grow (full.md §11).
  • Reserve top bar, thumbstick, jump, chat; interactive UI in CoreUISafeInsets; place by measured AbsolutePosition/AbsoluteSize.
  • Check every element pair that can show together; reflow, don't shrink.
  • Gamepad: one SelectedObject owner, SelectionGroup bounds, restored focus, layered Back (§8).
  • Console: TV-safe area, ViewportDisplaySize, no chat window.
  • Layouts own repeated layout; UI shows server state; a button is not an authority boundary.
  • Reactive UI: per-screen cleanup; repeat open/close to test leaks. Loading UI in ReplicatedFirst.
  • TextBox submit, grids, truncation, RichText safety, deprecated APIs: full.md.
