Wowngeon

A blockchain-based roguelike dungeon crawler built on the Wownero network.

Project Overview

Wowngeon is a web-based roguelike game that integrates with the Wownero blockchain for a unique gaming experience. Players enter a randomly generated dungeon with the goal of escaping before the next block is discovered on the network.

Key Features:

• Blockchain-linked gameplay: Players enter when one block is found and must escape before the next block (approximately 5 minutes in Wownero)
• Permadeath mechanics: If a player fails to escape before the next block is found, they die
• Random dungeons: Each game features procedurally generated maps using ROT.js
• Monster AI: Evade monsters as you navigate the dungeon
• Treasure hunting: Find treasure for bonus rewards
• Wownero integration: Players pay an entrance fee (10-100 WOW) and can win rewards

Technology Stack:

• Backend: Node.js with Express and Socket.io
• Frontend: HTML5, CSS, and JavaScript with ROT.js for rendering
• Blockchain: Wownero RPC integration for block monitoring and transactions

File Structure

Server Files

index.js
The main server file that handles HTTP requests, WebSocket connections, game lifecycle management, and blockchain monitoring. Coordinates the entire application.

game.js
Contains the Game class and logic for dungeon generation, player movement, monster AI, field-of-view calculations, and game state management.

user.js
Manages user registration, authentication, game association, and payment tracking. Maintains a registry of all active users.

dbcalls.js
Handles database operations for storing user data, game history, and payment records.

rpccalls.js
Contains functions for interacting with the Wownero blockchain via RPC, including checking block height and verifying transactions.

Client Files

html/index.html
The main HTML file served to clients, containing the structure for the game UI and chat interface.

html/js/game.js
Client-side game logic handling keyboard input, rendering the game state using ROT.js, and managing socket communication.

html/styles/stylesheet.css
Styling for the game interface, ensuring proper layout and visual appeal.

html/js/rot.js
The Roguelike Toolkit library that provides dungeon generation, field-of-view calculations, and display capabilities.

To-Do List

High Priority

• Fix monster collision detection to properly end game when monster catches player
• Improve chat system to correctly broadcast messages between all clients
• Add visual indicators for block time status (when you're in danger)
• Implement proper payment verification through Wownero RPC
• Add score tracking and leaderboard functionality

Medium Priority

• Improve monster AI with more sophisticated pathfinding
• Add multiple dungeon layouts and difficulty levels
• Implement different monster types with varying behaviors
• Create persistent user accounts with game history
• Add sound effects and basic animations

Low Priority

• Implement additional power-ups or items in the dungeon
• Add achievements system
• Create detailed statistics tracking
• Optimize performance for mobile devices
• Add difficulty settings with corresponding reward multipliers

Running the Game

1. Install dependencies: npm install
2. Configure Wownero RPC settings in config.js or environment variables
3. Start the server: node index.js
4. Access the game at http://localhost:3000

Development Mode

The game includes a DEBUG_MODE setting that simulates block discovery every 30 seconds for easier testing. Set DEBUG_MODE = true in index.js to enable this feature.
