# roblox gui

## When to Load

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

+ Load for HUDs, menus, shops, dialogs, notifications, or world-space UI.

## 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; loading UI in `ReplicatedFirst`.

+ - `ScreenGui` overlays; `SurfaceGui` on surfaces; `BillboardGui` for world labels.

+ - Let layouts and constraints own repeated layout; avoid per-frame pixel positioning.

+ - `Scale` for responsive structure; `Offset` for padding/fixed-size details.

+ - Design for touch/gamepad too. Use `ContextActionService` for gameplay bindings where appropriate.

+ - Test directional focus; set `GuiService.SelectedObject` for gamepad entry.

+ - Follow existing visual language and owner art direction; test UI over the game world.

+ - UI displays server state; a button is not an authority boundary.

+ - Reactive UI: own per-screen cleanup separately from session state; repeat open/close to test leaks (full.md).

+ - Server Authority: display confirmed inventory/currency; route gameplay input through Input Actions.

+ - Resolve scrolling, text growth, clipping, and safe areas before polish.

+ - TextBox submit, grids, truncation, RichText safety, and deprecated APIs: full.md.

+ - Loading UI belongs in `ReplicatedFirst`; client character teleports are not readiness gates.
