Wowngeon is a browser-based roguelike that synchronizes dungeon runs with Monero (XMR) and Wownero (WOW) block timing. The backend is a Node.js/Express server with Socket.IO for realtime play, optional payment enforcement, and automated payouts.
|
||||
|
||||
## Overview
|
||||
|
||||
Wowngeon is a web-based roguelike game that integrates with Monero (XMR) and Wownero (WOW) networks for a unique crypto-gaming experience. Players enter randomly generated dungeons with the goal of escaping before the next blockchain block is discovered. The game features three distinct game modes with optional payment integration.
|
||||
- Multiplayer dungeon crawler rendered in the browser
|
||||
- Three game modes with configurable pricing and payouts
|
||||
- Optional crypto payments with automatic subaddress management
|
||||
- Centralized error handling, rate limiting, and memory management
|
||||
- Jest coverage for wallet RPC interactions, payment flow, security checks, and game helpers
|
||||
|
||||
## Game Modes
|
||||
|
||||
### 🆓 **FREE Mode**
|
||||
- Unlimited free play
|
||||
- No payments required
|
||||
- Full game features available
|
||||
The unified payment config exposes two monetized modes. They map to the legacy identifiers still exposed over the socket and REST APIs.
|
||||
|
||||
### 💰 **PAID_SINGLE Mode**
|
||||
- Pay per game (default: 0.005 XMR)
|
||||
- 2x payout for successful escape
|
||||
- 3x payout for escape with treasure
|
||||
- Automatic payouts to user addresses
|
||||
| Legacy Identifier | Unified Key | Description | Default Cost¹ | Default Payout |
|
||||
| --- | --- | --- | --- | --- |
|
||||
| `FREE` | n/a | Payments disabled. Runs never require a wallet or address. | n/a | n/a |
|
||||
| `PAID_SINGLE` | `direct` | Per-run charge. Requires a confirmed payout address unless `DIRECT_REQUIRES_ADDRESS=false`. | 1 WOW (1e11 atomic) | 2× escape, 3× escape+treasure |
|
||||
| `PAID_CREDITS` | `credits` | Credit bundles; each run consumes one credit. Mixed mode allowed when `ALLOW_MIXED_MODE=true`. | 10 credits for 5 WOW (small bundle) | Credits only (payouts disabled) |
|
||||
|
||||
### 🎫 **PAID_CREDITS Mode**
|
||||
- Buy 10-game credit packages (default: 0.05 XMR)
|
||||
- Play 10 games with purchased credits
|
||||
- No individual payouts (credits consumed)
|
||||
¹ Atomic amounts use 11 decimal places (Monero/Wownero standard). Update `DIRECT_GAME_PRICE` or `CREDITS_PACKAGES` to change pricing. Config changes take effect when the snapshot refreshes or the process restarts.
|
||||
|
||||
## Payment System Features
|
||||
## Payment System
|
||||
|
||||
### 🔍 **Automatic Address Detection**
|
||||
- Paste XMR/WOW addresses directly in chat
|
||||
- Automatic regex-based detection with confirmation
|
||||
- Security warnings about clipboard viruses
|
||||
- Two-step confirmation process for safety
|
||||
- **Wallet RPC service** (`walletRPCService.js`): Handles subaddress creation, monitors payments, and batches payouts. Errors are wrapped in typed exceptions for consistent handling.
|
||||
- **Game Mode manager** (`gameModeManager.js`): Applies payment configuration, validates player state, and coordinates payouts.
|
||||
- **Payment handlers** (`paymentHandlers.js`): Manages request lifecycle, socket notifications, and queue integration.
|
||||
- **Environment validator** (`config/environmentValidator.js`): Rejects unsafe payment configs and falls back to `FREE` mode when necessary.
|
||||
- **Address detection** (`network/addressManager.js`): Parses XMR/WOW addresses shared in chat and requests confirmation before storing them.
|
||||
|
||||
### 💳 **Wallet-RPC Integration**
|
||||
- Subaddress generation for payments
|
||||
- Real-time payment monitoring
|
||||
- Automated payment confirmations
|
||||
- Batch payout processing
|
||||
If the wallet RPC service or configuration is unavailable the backend automatically downgrades to `FREE` mode so players can still start games.
|
||||
|
||||
### 🛡️ **Security & Reliability**
|
||||
- PostgreSQL database with comprehensive schema
|
||||
- RPC failover system (primary/fallback endpoints)
|
||||
- Graceful degradation to FREE mode if payment system fails
|
||||
- Extensive error handling and logging
|
||||

|
||||
## Payment Flow
|
||||
- Amounts are specified in atomic units (1 WOW = 1e11) unless otherwise noted.
|
||||
- Leave wallet credentials unset to enforce `FREE` mode; payments require RPC access.
|
||||
- `CREDITS_PACKAGES` must be valid JSON encoded as a single-line string. Adjust the bundle list to match your pricing model.
|
||||
- The legacy `GAME_MODE`, `SINGLE_GAME_PRICE`, and `CREDITS_PACKAGE_PRICE` variables remain for compatibility but are ignored when `PAYMENT_MODES` is set.
|
||||
|
||||
### PAID_SINGLE Mode
|
||||
1. User requests to play paid game
|
||||
2. System generates Wallet-RPC payment request
|
||||
3. User completes payment (0.005 XMR default)
|
||||
4. Game starts after payment confirmation
|
||||
5. Automatic 2x or 3x payout on successful escape
|
||||
## Payment Flow Summary
|
||||
|
||||
### PAID_CREDITS Mode
|
||||
1. User purchases 10-game credit package (0.05 XMR default)
|
||||
2. Credits added to user account after payment
|
||||
3. Each game consumes one credit
|
||||
4. No individual payouts (credits are the value)
|
||||
**`PAID_SINGLE`**
|
||||
1. Player requests a paid run.
|
||||
2. Server creates a subaddress and returns the payment details.
|
||||
3. Wallet RPC monitors the subaddress and signals confirmation.
|
||||
4. Game starts; payouts run after successful completion.
|
||||
|
||||
### Address Detection Workflow
|
||||
1. User pastes XMR/WOW address in chat
|
||||
2. System detects address via regex pattern matching
|
||||
3. Security warning displayed about clipboard viruses
|
||||
4. User confirms address in two-step process
|
||||
5. Address saved for automatic payouts
|
||||
**`PAID_CREDITS`**
|
||||
1. Player buys a ten-run bundle.
|
||||
2. Credits are recorded in the database on confirmation.
|
||||
3. Each game consumes one credit; no automatic payouts occur.
|
||||
|
||||
## Game Controls & Features
|
||||
|
||||
- **WASD** or **Arrow Keys**: Move player through dungeon
|
||||
- **Enter**: Enter dungeon when block timing allows
|
||||
- **Chat**: Commands and communication (with address detection)
|
||||
- **Real-time Multiplayer**: See other players and chat in real-time
|
||||
- **Blockchain Integration**: Game timing tied to block discoveries
|
||||
**Address confirmation**
|
||||
1. Player pastes an address in chat.
|
||||
2. Regex detection flags the message and issues a warning.
|
||||
3. Player confirms; the address is persisted for payouts.
|
||||
|
||||
## Testing
|
||||
|
||||
The payment system includes comprehensive test coverage:
|
||||
Run the Jest suite from `src`:
|
||||
|
||||
```bash
|
||||
# Run address detection tests
|
||||
cd test
|
||||
node test_address_detection.js
|
||||
```
|
||||
|
||||
Test suite covers:
|
||||
- XMR address pattern matching (95 characters, starts with 4/8/A/B)
|
||||
- WOW address pattern matching (97 characters, starts with W)
|
||||
- Invalid address rejection
|
||||
- Regex boundary conditions
|
||||
|
||||

## 🤝 Support & Contributing
|
||||
|
||||
### **📚 Documentation**
|
||||
- **Architecture**: See `REFACTORING_SUMMARY.md` for detailed technical architecture
|
||||
- **Security**: Review security test suite in `/test/security.test.js`
|
||||
- **Examples**: Check environment configuration in `.env.example`
|
||||
- **Components**: Each module includes comprehensive inline documentation
|
||||
|
||||
### **🧪 Development & Testing**
|
||||
```bash
|
||||
# Run comprehensive test suite
|
||||
npm test
|
||||
|
||||
# Test individual components
|
||||
node -c src/network/rateLimiter.js # Rate limiting
|
||||
node -c src/network/connectionHandler.js # Connection management
|
||||
node -c src/game/gameManager.js # Game lifecycle
|
||||
node -c src/utils/memoryManager.js # Memory management
|
||||
|
||||
# Security testing
|
||||
node test/security.test.js # SQL injection prevention
|
||||
```
|
||||
|
||||
### **🔍 Monitoring & Debugging**
|
||||
- Component-level statistics available via WebSocket commands
|
||||
- Comprehensive logging with configurable debug levels
|
||||
- Health check endpoints for production monitoring
|
||||
- Memory usage tracking and cleanup reporting
|
||||
Tests cover payment handlers, wallet RPC error propagation, security rules, movement logic, and integration flows. Additional manual scripts live under `test/` for browser debugging and lighting verification.
|
||||
|
||||
**The payment system is designed to be robust, secure, and user-friendly while maintaining the core gaming experience even when payment features are unavailable. The 2025 refactoring ensures enterprise-grade reliability, security, and maintainability.**
|
||||
## Monitoring and Operations
|
||||
|
||||
- Rate limiting metrics and in-memory cleanup stats are exposed through server logs and debug views.
|
||||
- Optional health endpoints provide game counts, queue length, and rate limiter state.
|
||||
- Structured error handling ensures failed wallet or RPC calls return consistent payloads and are logged with context.
