From ba687ea13000c110f2a145017d67f838d7ee5d2b Mon Sep 17 00:00:00 2001 From: tiennm99 Date: Tue, 21 Apr 2026 22:40:53 +0700 Subject: [PATCH] feat(game): wilting tomato mechanic replaces static light MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Static guards now emit a Manhattan aura that shrinks by 1 per turn until harmless (clamped at -1 to keep solver state finite). Level data schema change: 'static' guards now take 'initialRadius' instead of 'litCells'. All 27 static-guard entries migrated in one pass. L1 and L2 redesigned with real forced-zigzag walls — solver path is now 20 moves (vs Manhattan 14), so players must move AWAY from the goal to reach it. L2 adds three wilting tomatoes parked on the zigzag path as a gentle intro to the mechanic. Tests: +3 new tests on StaticGuard wilting behavior; all 70 tests pass. --- docs/code-standards.md | 2 +- docs/codebase-summary.md | 5 +- docs/game-design.md | 14 +-- src/lib/game/guards.js | 39 ++++++-- src/lib/game/guards.test.js | 30 ++++++- src/lib/game/level-manager.js | 2 +- src/lib/levels/levels.js | 165 ++++++++++------------------------ 7 files changed, 116 insertions(+), 141 deletions(-) diff --git a/docs/code-standards.md b/docs/code-standards.md index e31b0db..5efc585 100644 --- a/docs/code-standards.md +++ b/docs/code-standards.md @@ -278,4 +278,4 @@ audio.toggleMute(); - [ ] Pixel color semantics (`--guard-*` CSS vars ↔ `NNTV.guard*`) kept in sync when modifying theme - [ ] Any edit to `src/lib/levels/levels.js` runs `npm run test:solvability` and passes - [ ] L12 remains unsolvable (solver asserts this — never "fix" it) -- [ ] No guard's `litCells` entry overlaps a wall cell in the same level +- [ ] No blinking-guard `litCells` entry overlaps a wall cell in the same level (static guards use initialRadius auras, not litCells) diff --git a/docs/codebase-summary.md b/docs/codebase-summary.md index a49919b..c9bb8fc 100644 --- a/docs/codebase-summary.md +++ b/docs/codebase-summary.md @@ -103,7 +103,7 @@ NNTV is a turn-based stealth puzzle game built with Svelte 5 and Vite 6.x.
