The editor never requested occupied tiles, so tiles holding furniture
were indistinguishable from empty floor and could be edited/voided.
- request GetOccupiedTilesMessageComposer when the editor opens
- handle RoomOccupiedTilesMessageEvent -> SET_OCCUPIED_TILES
- new Tile.occupied flag (kept separate from `blocked`/void): occupied
tiles render with a distinct marker and are protected from PAINT/
ERASE/ADJUST and brush-to-selection edits
- occupied is purely informational and never changes the saved tilemap
(no accidental voiding of floor under furni)
Tests: reducer cases for SET_OCCUPIED_TILES + edit protection; container
test asserts the occupied event is non-destructive on save; route the
canvas pointer test through elementFromPoint (jsdom has no getScreenCTM).
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.
