# UNO Bot Integration - Implementation Summary
|
||||
|
||||
## ✅ What Has Been Implemented
|
||||
|
||||
### 1. Game State Export System ✅
|
||||
|
||||
**Location:** `/client/src/utils/gameStateBuilder.js`
|
||||
|
||||
The game now exports a comprehensive JSON state object at every turn containing:
|
||||
|
||||
```json
|
||||
{
|
||||
"game": {
|
||||
"isOver": false,
|
||||
"winner": null,
|
||||
"currentTurn": "Player 2",
|
||||
"turnNumber": 15
|
||||
},
|
||||
"currentCard": {
|
||||
"code": "5R",
|
||||
"type": "number",
|
||||
"value": 5,
|
||||
"color": "R",
|
||||
"colorName": "red",
|
||||
"displayName": "5 red"
|
||||
},
|
||||
"player2": {
|
||||
"cards": [...], // Full hand with playability info
|
||||
"playableCards": [...] // Only cards that can be played
|
||||
},
|
||||
"botContext": {
|
||||
"canPlay": true,
|
||||
"mustDraw": false,
|
||||
"actions": [...] // Available actions
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Card Parsing Utilities ✅
|
||||
|
||||
**Location:** `/client/src/utils/cardParser.js`
|
||||
|
||||
Comprehensive card parsing functions:
|
||||
- `parseCard(cardCode)` - Convert card codes to detailed objects
|
||||
- `isCardPlayable(cardCode, currentColor, currentNumber)` - Check if playable
|
||||
- `getPlayableCards(hand, currentColor, currentNumber)` - Filter playable cards
|
||||
|
||||
**Card Format Support:**
|
||||
- Number cards: `0R`, `5G`, `9B`, `3Y`
|
||||
- Skip: `skipR`, `skipG`, `skipB`, `skipY`
|
||||
- Reverse: `_R`, `_G`, `_B`, `_Y`
|
||||
- Draw 2: `D2R`, `D2G`, `D2B`, `D2Y`
|
||||
- Wild: `W`
|
||||
- Draw 4 Wild: `D4W`
|
||||
|
||||
### 3. Automatic Game State Logging ✅
|
||||
|
||||
**Location:** `/client/src/components/Game.js` (lines ~169-199)
|
||||
|
||||
Added `useEffect` hook that:
|
||||
- Monitors all game state changes
|
||||
- Logs simplified state to console: `🎮 UNO GAME STATE (Simplified)`
|
||||
- Logs full state to console: `🤖 FULL GAME STATE (For Bot)`
|
||||
- Logs formatted JSON: `📋 JSON for Bot API`
|
||||
- Emits state via Socket.IO event: `botGameState`
|
||||
|
||||
### 4. HTTP API Endpoints ✅
|
||||
|
||||
**Location:** `/server.js`
|
||||
|
||||
#### GET `/api/game/:roomCode/state`
|
||||
Retrieve current game state for a room.
|
||||
|
||||
**Example:**
|
||||
```bash
|
||||
curl http://localhost:5000/api/game/ABC123/state
|
||||
```
|
||||
|
||||
**Response:**
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"gameState": { /* full state */ },
|
||||
"timestamp": "2026-01-25T10:30:00.000Z"
|
||||
}
|
||||
```
|
||||
|
||||
#### POST `/api/game/:roomCode/action`
|
||||
Submit bot action (play card or draw).
|
||||
|
||||
**Example:**
|
||||
```bash
|
||||
curl -X POST http://localhost:5000/api/game/ABC123/action \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"action":"play_card","cardCode":"5R","chosenColor":null}'
|
||||
```
|
||||
|
||||
### 5. Socket.IO Events ✅
|
||||
|
||||
**New Server Events:**
|
||||
- `botGameState` - Receives and stores game state from Player 2
|
||||
- `botAction` - Receives action from bot
|
||||
- `requestGameState` - Bot requests current state
|
||||
- `botActionReceived` - Forwards HTTP actions to game
|
||||
|
||||
### 6. Documentation ✅
|
||||
|
||||
Created comprehensive documentation:
|
||||
- **`BOT_INTEGRATION_GUIDE.md`** - Full integration guide (38KB)
|
||||
- **`BOT_QUICK_REF.md`** - Quick reference for developers
|
||||

## 🔄 Example Bot Decision-Making
|
||||
|
||||
Here's how Miku bot would play:
|
||||
|
||||
```python
|
||||
import requests
|
||||
import time
|
||||
|
||||
class MikuUnoPlayer:
|
||||
def __init__(self, base_url, room_code):
|

self.game_state = response.json()['gameState']
|
||||
return self.game_state
|
||||
|
||||
def is_my_turn(self):

return self.game_state['game']['currentTurn'] == 'Player 2'
|
||||
|

"""Simple AI decision"""
|
||||
playable = self.game_state['player2']['playableCards']
|
||||
|
||||
if not playable:
|
||||
return {'action': 'draw_card'}
|
||||
|
||||
# Strategy: Play highest value card
|
||||
best_card = max(playable, key=lambda c: c.get('value', 0))
|
||||
|

colors = {}
|
||||
for card in self.game_state['player2']['cards']:
|

|
||||
colors[card['color']] = colors.get(card['color'], 0) + 1
|
||||
chosen_color = max(colors, key=colors.get) if colors else 'R'
|

## 🐛 Known Issues & Solutions
|
||||
|
||||
### Issue: Node 25.3.0 Compatibility
|
||||
**Problem:** PostCSS subpath export errors with react-scripts 4.x
|
||||
|
||||
**Solution:**
|
||||
```bash
|
||||
# Use nvm to switch to Node 18
|
||||
nvm install 18
|
||||
nvm use 18
|
||||
```
|
||||
|
||||
### Issue: Old Lockfile Warnings
|
||||
**Problem:** npm warns about old lockfile format
|
||||
|
||||
**Solution:** This is cosmetic, doesn't affect functionality
|
||||
```bash
|
||||
npm install --legacy-peer-deps # If needed
|
||||
```
|
||||
|
||||
### Issue: Security Vulnerabilities
|
||||
**Problem:** 193 vulnerabilities in client dependencies
|
||||
|
||||
**Solution:** These are in dev dependencies and don't affect runtime security. For production, consider upgrading react-scripts to v5.x

## 📊 Testing Checklist
|
||||
|
||||
### Manual Testing
|
||||
- [ ] Start server: `npm start` in `/uno-online`
|
||||
- [ ] Start client: `npm start` in `/uno-online/client` (requires Node 18)
|
||||
- [ ] Create game in browser
|
||||
- [ ] Join as Player 2
|
||||
- [ ] Open browser console (F12)
|
||||
- [ ] Play some cards
|
||||
- [ ] Verify console logs show:
|
||||
- `🎮 UNO GAME STATE (Simplified)`
|
||||
- `🤖 FULL GAME STATE (For Bot)`
|
||||
- `📋 JSON for Bot API`
|
||||
- [ ] Copy JSON from console
|
||||
- [ ] Verify it has all necessary fields
|
||||
|
||||
### API Testing
|
||||
```bash
|
||||
# Get room code from game UI (e.g., "ABC123")
|
||||
|
||||
# Test GET endpoint
|
||||
curl http://localhost:5000/api/game/ABC123/state
|
||||
|
||||
# Test POST endpoint (draw card)
|
||||
curl -X POST http://localhost:5000/api/game/ABC123/action \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"action":"draw_card"}'
|
||||
|
||||
# Test POST endpoint (play card) - use actual card from your hand
|
||||
curl -X POST http://localhost:5000/api/game/ABC123/action \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"action":"play_card","cardCode":"5R","chosenColor":null}'
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 💡 Design Decisions
|
||||
|
||||
### Why JSON State Export?
|
||||
- **Structured:** Easy for LLMs to parse and understand
|
||||
- **Complete:** Includes all information needed for decisions
|
||||
- **Debuggable:** Can be logged, saved, analyzed
|
||||
- **Flexible:** Can be extended without breaking compatibility
|
||||
|
||||
### Why HTTP API + Socket.IO?
|
||||
- **HTTP:** Easy for external bots (Miku) to poll
|
||||
- **Socket.IO:** Real-time updates for active players
|
||||
- **Hybrid:** Best of both worlds
|
||||
|
||||
### Why Store State on Server?
|
||||
- **Stateless Bot:** Bot doesn't need to maintain connection
|
||||
- **HTTP Access:** Can query state via simple GET requests
|
||||
- **Scalable:** Can add caching, Redis, etc. later
|
||||
|
||||
### Why Parse Cards Client-Side?
|
||||
- **Immediate:** No round-trip to server
|
||||
- **Reusable:** Utility functions can be used elsewhere
|
||||
- **Testable:** Easy to unit test card logic

||||
|
||||
### For Understanding the System
|
||||
1. Read: `BOT_INTEGRATION_GUIDE.md` - Complete overview
|
||||
2. Read: `BOT_QUICK_REF.md` - Quick reference
|
||||
3. Check: `/client/src/utils/gameStateBuilder.js` - See state structure
|
||||
|
||||
### For Implementing Miku Integration
|
||||
1. Review: `BOT_INTEGRATION_GUIDE.md` sections:

|
||||
## 📝 Notes for Miku Bot Developer
|
||||
|
||||
### Important Considerations
|
||||
1. **Polling Frequency:** Don't poll too often (recommended: 2-3 seconds)
|
||||
2. **Error Handling:** Game might end, player might disconnect
|
||||
3. **Card Validation:** Always check `playableCards` array
|
||||
4. **Wild Cards:** Must provide `chosenColor` for W and D4W
|
||||
5. **UNO Button:** Bot should detect when it has 2 cards
|
||||
|
||||
### LLM Prompt Tips
|
||||
- Include current card prominently
|
||||
- List playable cards clearly
|
||||
- Mention opponent's card count
|
||||
- Keep rules concise
|
||||
- Request JSON response format
|
||||
|
||||
### Discord Integration Ideas
|
||||
- Embed with game state
|
||||
- Color-coded cards (emoji)
|
||||
- Real-time updates
|
||||
- Win/loss tracking
|
||||
- Personality-based responses
