# Wowngeon Code Architecture
## Overview
The Wowngeon roguelike game has been refactored into a modular architecture with clear separation of concerns between frontend and backend components. Recent major improvements include fixing critical movement bugs, implementing auto-start functionality, and resolving duplicate event handler issues.
## Recent Major Bug Fixes and Improvements
### 🎯 Movement System Overhaul
**Problem**: Players were skipping over tiles when moving through hallways, especially when approaching from certain directions.
**Root Cause**: Double event handler registration caused duplicate keydown events, leading to rapid-fire movement commands.
**Solution**:
- Added `_initialized` flags to prevent multiple initializations of InputHandler and SocketHandlers
- Implemented 100ms movement throttling on both client and server sides
- Enhanced movement validation and debugging with comprehensive logging
- Fixed module initialization order in `index.html`
**Result**: Players now move exactly one tile per keypress with no skipping.
### 🚀 Auto-Start System Implementation
**Problem**: Game was hanging on "waiting for server..." screen instead of starting immediately for testing.
**Root Cause**: Missing `SocketHandlers.init()` call in `index.html` meant client couldn't receive `game_start` events.
**Solution**:
- Added proper SocketHandlers initialization to HTML document ready function
- Implemented auto-start that sends "enter" command 500ms after connection
- Enhanced server-side auto-start to immediately begin games in DEBUG_MODE
- Improved error handling and connection flow
**Result**: Games now start instantly for faster development and testing.
### 🔧 Code Architecture Improvements
**Problem**: Monolithic code structure made debugging and maintenance difficult.
**Solution**:
- Split frontend JavaScript into focused modules (ui.js, socketHandlers.js, inputHandler.js)
- Added initialization protection to prevent duplicate module setup
- Enhanced logging with emojis and timing information for easier debugging
- Maintained backward compatibility while improving code organization
**Result**: Much cleaner, more maintainable codebase with improved debugging capabilities.
## Backend Architecture
### Core Classes
#### `Player` (/player.js)
- Manages player state and position
- Methods: `moveTo()`, `isAt()`, `getState()`, `setState()`, `reset()`
- Properties: x, y, hasKey, hasTreasure
#### `Monster` (/monster.js)
- Manages monster state and AI behavior
- Methods: `moveTowardPlayer()`, `hasCaughtPlayer()`, `getState()`, `setState()`
- AI Features: Smart pathfinding toward player, collision detection
#### `DungeonGenerator` (/dungeon.js)
- Handles procedural dungeon generation using ROT.js
- Methods: `generate()`, `getRandomRoomCenter()`, `isFloorTile()`, `isWallTile()`
- Features: Room placement, entrance/exit/treasure positioning
#### `Game` (/game.js)

# 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. The player requests to enter (and optionally pay an entrance fee), and then waits for the next block to be mined. When the next block is found, the player is placed in the dungeon and must escape before the next block is found. If they fail to escape, they die and lose their entrance fee. There is a singular monster and treasure in the dungeon. If the monster catches the player, they die. If the player finds the treasure and manages to escape, they could win 3x or 5x instead of just 2x for escaping sans treasure. The game is designed to be played in a web browser, making it accessible to a wide audience.
The game is built using Node.js for the backend, with Express and Socket.io for real-time communication. The frontend is developed using HTML5, CSS, and JavaScript, with ROT.js for rendering the dungeon and managing game mechanics. The Wownero blockchain is integrated via RPC calls to monitor block height and handle transactions.
### 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 monster 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
- **Chat system**: Players can communicate in real-time during gameplay
- **View other players' game states**: Spectate other players' dungeons in real-time
### 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
