feat: Colyseus authoritative server + invite-code lobby

Browse Source 
- Replace socket.io relay with Colyseus 0.15 authoritative server
- GameRoom with GameState schema (players, units, resources)
- Pure TS services: CombatResolver, EconomyService, PathfindingService, UnitManager
- POST /api/create-room → 4-char invite code
- React/MUI LobbyScreen: Create (shows code + START GAME) / Join by code
- ColyseusClient: joinOrCreate/join by room type = invite code
- Nginx: static assets direct, all else proxied to Colyseus (WS upgrade)
- Content-hashed JS bundles for Cloudflare cache-busting
- 1-player lobbies: START GAME button bypasses 2-player wait

# Debug UI - Entity Spawner
**Created:** 2026-05-24 01:48
**Author:** Hermes (game-designer profile input)
**Status:** Plan ready for review
---
## Goal
Add a debug UI panel to the Restitution game that allows developers to spawn entities (infantry, tanks) with selectable teams (Russia, Ukraine) at arbitrary map locations.
---
## Current Context
### Architecture
- **Frontend:** React 18 + Material-UI for UI overlays
- **Game Engine:** Phaser 3.55.2
- **Entity System:** FSM-based entities with states (IDLE, MOVING, SHOOTING, DYING)
- **Teams:** "Good Guys" (Ukraine) vs enemy container (Russia)
### Existing Components
- `src/components/app.jsx` - Main React app, mounts Phaser game
- `src/components/topBar.jsx` - Top navigation bar (MUI)
- `src/scenes/Map_Player.js` - Main game scene, creates initial infantry
- `src/entities/base-units/` - Entity classes (infantry, tank, team variants)
### Available Entities
```
infantry.js (base class)
├── ukrainian-infantry.js
├── russian-infantry.js
tank.js (base class)
├── ukrainian-tank.js (likely exists)
└── russian-tank.js (likely exists)
```
### Current Issues to Fix First
1. `interface.js:247` - `targetTile` is undefined when spawning infantry
2. `GetTilesWithinShape` error - tilemap type mismatch (orthogonal expected)
---
## Proposed Approach
### Design Principles (from game-designer profile)
- **Immersion-first:** Debug tools should feel like a "command console" not a dev menu
- **Minimal UI intrusion:** Collapsible panel, keyboard toggle (F3 or `)
- **Team clarity:** Clear visual distinction between Russia/Ukraine spawns
- **Quick iteration:** One-click spawn, drag-to-place workflow
### UI Component Structure
```
src/components/
├── debugPanel.jsx (NEW) - Main debug UI panel
├── entitySpawner.jsx (NEW) - Entity selection + spawn controls
└── teamSelector.jsx (NEW) - Russia/Ukraine toggle
```
### Integration Points
1. **React ↔ Phaser Communication**
- Expose `window.restitution` (already done in app.jsx)
- Add scene methods: `spawnEntity(type, team, tile)`
- Use React state to track selected entity/team
2. **Phaser Scene Methods**
```javascript
// In Map_Player.js
spawnEntity(entityType, team, tileXY) {
// entityType: 'infantry' | 'tank'
// team: 'ukraine' | 'russia'
// tileXY: {x, y} tile coordinates
}
```
3. **UI Toggle**
- Add keyboard listener in `interface.js` for debug panel toggle
- Panel overlays game canvas (z-index above Phaser)
---
## Step-by-Step Plan
### Phase 1: Fix Existing Bugs (Prerequisites)
- [ ] Fix `interface.js:247` - add null check for `targetTile`
- [ ] Fix tilemap error - verify map is orthogonal in `Map_Player.js`
- [ ] Rebuild and verify game loads without console errors
### Phase 2: Phaser Scene API
- [ ] Add `spawnEntity(type, team, tile)` method to `Map_Player.js`
- [ ] Add `getTileAtPointerXY()` helper for click-to-spawn
- [ ] Create entity factory function to handle team variants
### Phase 3: React Debug Components
- [ ] Create `debugPanel.jsx` - collapsible MUI panel
- Toggle with F3 key
- Position: bottom-right corner (out of camera way)
- Semi-transparent background
- [ ] Create `entitySpawner.jsx` - entity type selector
- Dropdown: Infantry, Tank
- Sprite preview when hovering
- [ ] Create `teamSelector.jsx` - team toggle
- Radio buttons: Ukraine (blue) / Russia (red)
- Visual color coding
### Phase 4: Integration
- [ ] Wire React state to Phaser via `window.restitution.scene`
- [ ] Add click handler: when panel open, clicks spawn entities
- [ ] Add keyboard shortcut (F3) to toggle panel visibility
- [ ] Add spawn confirmation (particle effect or sound)
### Phase 5: Polish
- [ ] Add spawn counter (total entities spawned this session)
- [ ] Add "Clear All Enemies" button for testing
- [ ] Add entity list (click to select existing entities)
- [ ] Add FPS counter toggle (Phaser built-in)
---
## Files to Change
### New Files
```
src/components/debugPanel.jsx
src/components/entitySpawner.jsx
src/components/teamSelector.jsx
src/styles/debugPanel.css
```
### Modified Files
```
src/components/app.jsx - import debug panel, add toggle state
src/scenes/Map_Player.js - add spawnEntity() method
src/phaserClasses/interface.js - add F3 keyboard handler
src/index.js - wire up debug panel to React tree
```
---
## Tests / Validation
### Manual Testing
1. Open game, press F3 - panel appears
2. Select "Infantry" + "Russia" - click on map - Russian infantry spawns
3. Select "Tank" + "Ukraine" - click on map - Ukrainian tank spawns
4. Spawn 50+ entities - verify no performance degradation
5. Toggle panel off/on - state persists
### Console Checks
- No React warnings about uncontrolled components
- No Phaser errors about missing textures
- Socket connections still work (no regression)
---
## Risks & Tradeoffs
### Risks
1. **Performance:** React re-renders during gameplay could cause stutter
- Mitigation: Use `React.memo()` on debug components, debounce state updates
2. **Input conflicts:** F3 might conflict with browser devtools
- Mitigation: Make keybinding configurable, add ` key as alternative
3. **Production leak:** Debug UI accidentally shipped to prod
- Mitigation: Wrap in `process.env.NODE_ENV === 'development'` check
### Tradeoffs
- **Option A: Full overlay UI** (proposed) - Rich UX but more React/Phaser sync complexity
- **Option B: Phaser-only debug menu** - Simpler integration but less polished, no MUI components
- **Option C: Browser console commands** - Zero UI but poor UX (`window.spawn('tank', 'russia', x, y)`)
**Recommendation:** Option A with environment gate for production.
---
## Open Questions
1. **Should debug UI be in production builds?**
- Hidden behind console command? Completely stripped?
2. **Spawn location precision:**
- Click-to-place (tile precision)?
- Drag-and-drop (pixel precision)?
3. **Entity limits:**
- Cap max spawned entities to prevent crashes?
- Add warning when exceeding N entities?
4. **Multiplayer sync:**
- Should spawned entities sync over socket.io?
- Or debug spawns are local-only for testing?
---
## Next Steps
1. Review this plan with Kay
2. Get game-designer profile feedback on UX flow
3. Implement Phase 1 (bug fixes)
4. Implement Phases 2-5 iteratively
5. Test on deployed environment
