From e24ed4153297d4745f085e5c298426965eb58ca7 Mon Sep 17 00:00:00 2001 From: robotica4us-collab Date: Sat, 21 Mar 2026 16:06:51 -0500 Subject: [PATCH] fix(issue-4): replace hardcoded BLOCKING_TYPES with metadata-driven ITEM_METADATA (#20) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(issue-4): add missing solid floor props to BLOCKING_TYPES Audited all furniture types defined in furnitureDefaults.ts and geometry.ts (ITEM_FOOTPRINT) against BLOCKING_TYPES in navigation.ts. Added five previously missing solid floor props: - water_cooler: freestanding floor appliance, agents pathfound through it - server_terminal: floor-standing terminal in the server room - dishwasher: floor appliance in the kitchen area - easel: floor-standing art-room prop - beanbag: floor seat large enough to obstruct walking paths Also adds a unit test asserting every newly-added type is correctly blocked in the nav grid, and that non-solid desk decorations (keyboard) remain free. * refactor(nav): replace hardcoded BLOCKING_TYPES with metadata-driven ITEM_METADATA Previously, buildNavGrid() maintained a hardcoded BLOCKING_TYPES set in navigation.ts. The issue #4 fix added the five missing solid props directly to that set, but this approach is brittle — every new furniture type requires a separate PR touching navigation.ts to stay correct. This rework introduces ITEM_METADATA in geometry.ts (alongside the existing ITEM_FOOTPRINT record) as the single source of truth for per-type navigation properties: export const ITEM_METADATA: Record Each item type explicitly declares blocksNavigation: true/false. The five props fixed in issue #4 (water_cooler, server_terminal, dishwasher, easel, beanbag) retain their blocking status. Unknown types default to false, so future decorative items never accidentally block navigation. Changes: - geometry.ts: add ITEM_METADATA export (64 type entries) - navigation.ts: remove BLOCKING_TYPES set; add itemBlocksNavigation() helper that reads ITEM_METADATA[type]?.blocksNavigation ?? false; update buildNavGrid() to call it - tests/unit/navigation.navBlockers.test.ts: retain original 5 solid-prop tests; add metadata-driven test suite covering: all blocking types from metadata, all non-blocking types from metadata, runtime-added type with blocksNavigation:true, and unknown-type safe fallback All 10 tests pass; lint clean; only pre-existing TS2367 (issue #13) remains. * test(navigation): add extended nav blocker tests (issue #4) Additional tests for buildNavGrid and astar pathfinding: - Adjacent blocking items create a continuous impassable wall - Blocking item near grid edge/boundary causes no out-of-bounds errors - Full pathfinding integration: astar routes AROUND a cabinet placed between start and end (not just that cells are blocked) - desk_cubicle explicitly does NOT block — confirmed via ITEM_METADATA - door explicitly does NOT block — agents must walk through doors --------- Co-authored-by: Neo (subagent) --- src/features/retro-office/core/geometry.ts | 74 ++++++ src/features/retro-office/core/navigation.ts | 48 +--- tests/unit/navigation.navBlockers.test.ts | 232 +++++++++++++++++++ 3 files changed, 316 insertions(+), 38 deletions(-) create mode 100644 tests/unit/navigation.navBlockers.test.ts diff --git a/src/features/retro-office/core/geometry.ts b/src/features/retro-office/core/geometry.ts index 6b5a7ec..70c55c4 100644 --- a/src/features/retro-office/core/geometry.ts +++ b/src/features/retro-office/core/geometry.ts @@ -97,6 +97,80 @@ export const getItemBaseSize = (item: FurnitureItem) => { };
