This commit fixes several issues in the core state management:
1. Fix deleteNodesAction recursive call issue
- Previously, the function recursively called get().deleteNodes()
inside the set() callback, which could cause state inconsistencies.
- Now collects all descendant IDs first in a separate pass, then
deletes them all in a single batch operation.
2. Fix memory leak in use-scene temporal tracking
- Module-level variables (prevPastLength, prevFutureLength,
prevNodesSnapshot) persisted across store re-creations.
- Now cleared in unloadScene() to release stale node references.
- Added clearTemporalTracking() helper function.
3. Remove unused variable in wall-system
- Removed debug variable 'useFrameNb' that was declared but never used.
4. Fix requestAnimationFrame in updateNodesAction
- Previously used RAF without cleanup, causing multiple queued
callbacks when updates happened rapidly.
- Now uses a single tracked RAF with cancellation support.

@pascal-app/core
Core library for Pascal 3D building editor.
Installation
npm install @pascal-app/core
Peer Dependencies

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>
}
