Complete modernization of the floor-plan editor. Three layered
changes shipped together since they share state shapes and the
test infrastructure stubs.
1) React rewrite (state + hooks + views + tests)
Drops the FloorplanEditorContext singleton + legacy view
components and replaces them with a pure-React reducer
architecture:
- state/ — typed FloorplanState + FloorplanAction union,
pure reducer covering PAINT_TILE / ERASE_TILE /
ADJUST_HEIGHT / SET_DOOR / SET_DOOR_DIR / SET_THICKNESS /
SET_WALL_HEIGHT / BRUSH_SET / SELECT_RECT / SELECT_ALL /
CLEAR_SELECTION / SQUARE_SELECT_TOGGLE / IMPORT_STRING /
APPLY_REMOTE_DIFF / APPLY_REMOTE_SNAPSHOT. Source-tagged
('local' | 'remote') so the editor can distinguish user
edits from server pushes. Co-located encoding helpers
(parseTilemap / serializeTilemap) and area-counter
selectors.
- hooks/ — useFloorplanReducer (wraps useReducer with a
history stack + loadFromServer + undo/redo), useTool
(pointer events -> dispatch), usePointerToTile (screen
-> tile projection that respects the viewBox origin so
pan/zoom stays accurate).
- views/ — FloorplanCanvasSVG, FloorplanHeightPicker,
FloorplanToolbar, FloorplanOptionsPanel,
FloorplanImportExport, FloorplanTile,
FloorplanPreviewSVG (alternative iso preview kept as a
fallback view, not wired into the main layout).
- Co-located Vitest suites for every module above (encoding,
reducer, selectors, hooks, views, integration). 100+ new
test cases.
2) Live in-room preview (NEW capability)
useFloorplanLiveSync drives client-side preview of the edit
directly into the active room — every tile / door / wall
height / thickness change is applied through
GetRoomMessageHandler().applyFloorModelLocally (new public
method on the renderer, see paired renderer PR) with
zero server traffic during editing. The wire
UpdateFloorPropertiesMessageComposer is only sent when the
user explicitly clicks Save. Thickness slider additionally
calls RoomEngine.updateRoomInstancePlaneThickness for
zero-latency wall/floor-depth feedback while dragging.
Toggle 'Live preview ON / OFF' in the bottom strip (default
ON) lets the user opt out if they want to keep changes
contained to the editor's own preview until Save.
Revert button re-applies the original snapshot locally so
the room snaps back to where it was when the editor opened.
3) UX polish
- Undo / Redo (Ctrl+Z, Ctrl+Shift+Z / Ctrl+Y) backed by a
100-step history stack inside useFloorplanReducer. Local
mutating actions push history; brush/selection UI bumps
and remote dispatches bypass it; loadFromServer wipes the
stack.
- Zoom 40-600 % with Ctrl+wheel, +/- buttons, % label.
Shift+drag or middle-mouse drag pans the canvas.
- Auto-fit on first paint: computes the screen-space
bounding box of the painted (non-blocked) tiles, picks the
zoom that just contains them with a 5 % margin, pans so
the room sits in the viewport centre. Default view is now
'room fills the canvas' instead of 'room is a dot at the
top-centre of a huge empty canvas'. Clicking the % label
re-runs the fit; crosshair button keeps zoom and recentres
the pan only.
- Door direction control: arrows + door icon triplet
(8-way rotate by single click on prev/next, full cycle
forward on the icon itself). Wall and floor thickness
collapse from two 4-button rows into two compact
segmented selectors (active state in emerald). Saves
significant horizontal space.
- Habbo floor pattern tile (~186 B PNG, vendored from
habbofurni.com/images/furni_floor.png) tiled as the
canvas background with image-rendering: pixelated so the
texture stays crisp at every zoom level. Replaces the
solid black background.
Test infrastructure
nitro-renderer.mock grows constructors / proxies / functions
for everything the new floor-editor tests transitively
import (floor composers + events, RoomEngineEvent,
ILinkEventTracker, convertNumbersForSaving /
convertSettingToNumber, GetRoomMessageHandler,
GetTicker, GetRenderer, NitroTicker, RoomPreviewer with a
sufficiently real .updatePreviewModel / dispose surface,
and a TextureUtils.createRenderTexture that returns an
object with a no-op .destroy). test-setup adds a no-op
ResizeObserver polyfill (jsdom doesn't ship one and the
optional FloorplanRoomPreview observes its container) and
a draggable-windows-container portal root for tests that
mount NitroCardView.
Files: 44 changed (mostly new). yarn typecheck 0 errors,
yarn test 341/341 green.
Run eslint --fix across src/ to clear ~1900 mechanical lint errors
surfaced by the @typescript-eslint v8 + react-hooks v7 + react-compiler
upgrade in the React 19 modernization PR.
Issues fixed automatically:
- brace-style (Allman): try/catch one-liners reformatted to multi-line
- indent: tab-vs-space and depth corrections
- semi: missing trailing semicolons
- no-trailing-spaces
No semantic changes. Remaining 701 errors are real-code issues
(set-state-in-effect, rules-of-hooks, no-unsafe-* type checks) that
need manual per-file review.

Adopt React 19 idioms across the codebase. The runtime was already on
react@19.2.5 but no React 19 APIs were in use.
- forwardRef -> ref-as-prop in 7 layout/component files
(NitroInput/Button/ItemCountBadge/Card×5/InfiniteGridItem,
ToolbarItemView, AvatarEditorIcon)
- <Ctx.Provider> -> <Ctx> in 6 contexts (CatalogAdmin, FloorplanEditor,
UiSettings, GridContext, NitroCardContext, NitroCardAccordionContext)
- Native <script> hoisting for Turnstile, ExternalPluginLoader, GoogleAdsView
(React 19 dedupes by src; removes manual document.head.appendChild +
module-level promise caches)
- React Compiler enabled at build time via babel-plugin-react-compiler
in vite.config.mjs (target: '19'), plus eslint-plugin-react-compiler
in lint mode
- Global <ErrorBoundary> + <Suspense> in src/index.tsx using
react-error-boundary, with LoadingView as fallback
- BackgroundsView migrated to use(promise) as a demonstrator pattern
for Suspense-driven config loading
- ESLint react setting bumped 18.3.1 -> 19.2; legacy
@typescript-eslint/ban-types replaced with no-restricted-types
(the old rule was removed in @typescript-eslint v8)
- Refresh public/configuration/{asset-loader,bootstrap}.js to match
current write-asset-loader.mjs output
Phase 3 (login forms -> useActionState/useFormStatus) deferred:
LoginView is 1623 lines with lockout + Turnstile + heartbeat
interleaving; safer as its own PR.

Redesign the floor plan editor with side-by-side layout featuring:
- Real-time isometric 3D preview that updates as tiles are drawn
- Vertical height gradient selector with COLORMAP colors
- Area counter showing total and walkable tile counts
- Zoom controls (+/-) on the 2D canvas
- Simplified single-row toolbar
- Wall height control in the preview panel
