* feat(editor): shelf placement validity box + sync tool for positioned presets Give the generic move tool a green/red footprint box for shelf placement, matching the GLB item cursor, and drop the vertical-arrow CursorSphere for shelves. Box colour comes from canPlaceOnFloor; an invalid (red) drop is refused unless Shift forces it, and R/T play the rotate sfx. Re-sync the box transform on node change so a re-armed clone isn't left at the previous rotation/position. Extract the box wireframe geometry helpers into a shared placement-box-geometry module reused by the item coordinator and the new declarative PlacementBox component. Export the Tool type so host apps can set the active tool for a positioned preset.

Formatting only — no behavior change. Also exclude **/next-env.d.ts from biome: Next regenerates it (double quotes + semicolon) on every build, so biome kept reformatting it into a perpetual dirty diff. Ignoring it lets Next own the file. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
@pascal-app/core
Core library for Pascal 3D building editor.
Installation
npm install @pascal-app/core
Peer Dependencies
npm install react three @react-three/fiber @react-three/drei
What's Included
- Node Schemas - Zod schemas for all building primitives (walls, slabs, items, etc.)
- Scene State - Zustand store with IndexedDB persistence and undo/redo
- Systems - Geometry generation for walls, floors, ceilings, roofs
- Scene Registry - Fast lookup from node IDs to Three.js objects
- Spatial Grid - Collision detection and placement validation
- Event Bus - Typed event emitter for inter-component communication
- Asset Storage - IndexedDB-based file storage for user-uploaded assets
Usage
import { useScene, WallNode, ItemNode } from '@pascal-app/core'
// Create a wall
const wall = WallNode.parse({
points: [[0, 0], [5, 0]],
height: 3,
thickness: 0.2,
})
useScene.getState().createNode(wall, parentLevelId)
// Subscribe to scene changes
function MyComponent() {
const nodes = useScene((state) => state.nodes)
const walls = Object.values(nodes).filter(n => n.type === 'wall')
return <div>Total walls: {walls.length}</div>
}
