Two related changes from the latest feedback:
1) Hand is now the FIRST button in the toolbar (left of the
'Modalita disegno' label), matching where users typically
look for a pan affordance in painting / mapping editors.
2) The hand and the brush buttons form one exclusive tool
group: picking any brush (SET / UNSET / UP / DOWN / DOOR)
- or select-all / square-select - clears pan mode. No more
'I clicked SET but the canvas keeps panning'. Same goes
the other way: clicking the hand stays sticky, and while
it's active the brush highlights are visually de-selected
even though state.brush.action still holds the last brush
(so the user gets it back the moment they pick a brush
again).
Implementation: replaced the toolbar's onTogglePanMode prop
with an imperative setPanMode(next: boolean) =>. Every other
tool's onClick calls exitPan() first; the hand calls
setPanMode(!panMode) directly. data-active and the border
highlight on the brush + square-select buttons now require
!panMode so the visual state mirrors the gesture state.
No reducer changes - panMode stays a canvas-level UI flag.
Two related polish improvements after the swatch-column → vertical-
slider swap.
Slider
- Wider track (18 px, was 14 px) for a more comfortable click area
with the same on-screen footprint.
- Min / max chips above and below the rail (HEIGHT_BRUSH_MIN /
_MAX) so users know which end is high and which is low without
hovering to discover.
- Thumb now uses a warm amber radial gradient (#fff7c4 → #facc15
→ #ca8a04) on a dark brown border with a soft drop shadow + inset
highlight, instead of the flat yellow disc. Hover adds a white
ring; drag swaps it for a darker ring — clear gesture feedback.
- Track gains a hover/drag glow (inset white seam + amber outline
via boxShadow) so you can tell the slider has focus before you
even click.
Hand tool (canvas pan)
- New FloorplanToolbar button (FaHandPaper, sticky toggle, emerald
fill when active) ties to a new state lifted into
FloorplanEditorView. When the hand is active, plain left-click
+ drag pans the canvas instead of brushing tiles. Cursor flips
to grab / grabbing accordingly.
- FloorplanCanvasSVG's isPanGesture predicate becomes:
middle-mouse OR Shift+left-click OR (panMode && left-click).
Shift / middle still work whether or not the hand is on so power
users keep their muscle memory.
- No change to the reducer (panMode is a canvas-level UI flag, not
a brush action — keeps state/types tight).
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.
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
