## Completed
|
||
|
||
### Phase 0: Project Setup ✅
|
||
- [x] Game Design Document (`synthesis-gdd.md`)
|
||
- [x] Engine analysis and tech stack selection (`engine-analysis.md`)
|
||
- [x] npm project + dependencies (Phaser 3, bitECS, TypeScript, Vite, Vitest)
|
||
- [x] TypeScript strict config
|
||
- [x] Vite config (HMR, chunk splitting)
|
||
- [x] Phaser config (1280x720, pixel-art, arcade physics, top-down)
|
||
- [x] BootScene with title screen
|
||
- [x] Cursor rules (6 rules: project context, agent workflow, ECS, chemistry, Phaser, data)
|
||
- [x] Implementation plan (`IMPLEMENTATION-PLAN.md`)
|
||
- [x] Progress tracking (this file)
|
||
|
||
### Phase 1: Chemistry Engine ✅
|
||
- [x] 1.1 Types and interfaces (`src/chemistry/types.ts`)
|
||
- [x] 1.2 Element data — 20 real elements (`src/data/elements.json`)
|
||
- [x] 1.3 Element registry with lookup by symbol/number (`src/chemistry/elements.ts`)
|
||
- [x] 1.4 Reaction engine — O(1) lookup, condition checking, failure reasons (`src/chemistry/engine.ts`)
|
||
- [x] 1.5 Reaction data — 34 real reactions (`src/data/reactions.json`)
|
||
- [x] 1.6 Compound data — 25 compounds with game effects (`src/data/compounds.json`)
|
||
- [x] 1.7 Unit tests — 35 passing (`tests/chemistry.test.ts`)
|
||
|
||
### Phase 2: ECS Foundation ✅
|
||
- [x] 2.1 World setup — bitECS world + time tracking (`src/ecs/world.ts`)
|
||
- [x] 2.2 Core components — Position, Velocity, SpriteRef, Health, ChemicalComposition (`src/ecs/components.ts`)
|
||
- [x] 2.3 Movement system — velocity-based + bounce (`src/ecs/systems/movement.ts`)
|
||
- [x] 2.4 Phaser ↔ bitECS sync bridge — polling-based, creates/destroys/syncs sprites (`src/ecs/bridge.ts`)
|
||
- [x] 2.5 Entity factory — createGameEntity/removeGameEntity (`src/ecs/factory.ts`)
|
||
- [x] 2.6 Health/damage system — damage, healing, death detection (`src/ecs/systems/health.ts`)
|
||
- [x] 2.7 Visual test — 20 colored circles bouncing at 60fps, GameScene (`src/scenes/GameScene.ts`)
|
||
- [x] Unit tests — 39 passing (`tests/ecs.test.ts`)
|
||
|
||
### Phase 3: World Generation ✅
|
||
- [x] 3.1 Tilemap system — canvas tileset with per-pixel variation + Phaser tilemap (`src/world/tilemap.ts`)
|
||
- [x] 3.2 Biome data — Catalytic Wastes: 8 tile types (`src/data/biomes.json`)
|
||
- [x] 3.3 Noise generation — simplex-noise, seeded PRNG (mulberry32), deterministic (`src/world/noise.ts`)
|
||
- [x] 3.4 World generator — elevation noise → base terrain, detail noise → overlays (`src/world/generator.ts`)
|
||
- [x] 3.5 Resource placement — geysers on acid-shallow zones, mineral veins on ground (`src/world/generator.ts`)
|
||
- [x] 3.6 Camera — WASD movement, mouse wheel zoom (0.5x–3x), bounds clamping (`src/world/camera.ts`)
|
||
- [x] 3.7 Minimap — canvas-based 160x160 overview, viewport indicator, border (`src/world/minimap.ts`)
|
||
- [x] Unit tests — 21 passing (`tests/world.test.ts`)
