# 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.
## 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)
- Main game logic coordinator
- Uses Player, Monster, and DungeonGenerator classes
- Manages game state, FOV calculation, and entity interactions
- Methods: `movePlayer()`, `moveMonster()`, `getState()`, `updateFOV()`
### Supporting Files
- `user.js` - User management and game instantiation
- `index.js` - Server entry point and socket handling
- `dbcalls.js` - Database operations
- `rpccalls.js` - Wownero blockchain integration
## Frontend Architecture
### Modular JavaScript Components
#### `ui.js`
- UI utilities and visual helpers
- Functions: `scrollChat()`, `updateBlockHeight()`, `updateFocusIndicator()`
- Manages teletype animations and browser detection
#### `socketHandlers.js`
- All WebSocket event handlers
- Events: connect, game_start, game_update, game_over, etc.
- Clean separation of network communication logic
#### `inputHandler.js`
- Keyboard and form input management
- Handles WASD/arrow key movement, chat input, focus management
- Event delegation for game controls
#### `game.js` (frontend)
- Core game rendering and client-side state management
- ROT.js display integration, FOV rendering, entity drawing
- Maintained original structure for compatibility
### HTML Structure
- `index.html` - Streamlined main page that loads modular components
- `index_original.html` - Backup of original monolithic structure
## Key Improvements
### Backend Benefits
1. **Modularity**: Clear separation of Player, Monster, and Dungeon logic
2. **Maintainability**: Each class has single responsibility
3. **Testability**: Individual components can be unit tested
4. **Extensibility**: Easy to add new entity types or game mechanics
### Frontend Benefits
1. **Reduced Complexity**: 471-line index.html reduced to ~80 lines
2. **Code Organization**: Related functionality grouped into logical modules
3. **Reusability**: UI and input handlers can be reused/extended
4. **Debugging**: Easier to locate and fix issues in specific modules
## File Structure
```
/wowngeon/
├── Backend Classes
│ ├── player.js # Player entity and state
│ ├── monster.js # Monster AI and behavior
│ ├── dungeon.js # Procedural generation
│ └── game.js # Main game coordinator
├── Backend Support
│ ├── index.js # Server and socket handling
│ ├── user.js # User management
│ └── ...other files
└── Frontend
├── index.html # Clean modular HTML
└── js/
├── game.js # Core game rendering
├── ui.js # UI utilities
├── socketHandlers.js # Network communication
├── inputHandler.js # Input management
└── ...libraries
```
## Migration Summary
- ✅ Backend modularized into Player, Monster, DungeonGenerator classes
- ✅ Frontend split into logical modules (UI, Socket, Input handlers)
- ✅ Removed unused files (game_refactored.js, displayManager.js, etc.)
- ✅ Maintained full game functionality and compatibility
- ✅ All game mechanics verified working (movement, FOV, collision, treasure)
## Testing Verification
- [x] Server starts without errors
- [x] Game initialization works
- [x] Player movement functional
- [x] Monster AI and collision detection operational
- [x] Treasure collection working
- [x] Frontend modules load correctly
- [x] All socket events properly handled
The refactored codebase is now much more maintainable and follows modern software engineering practices while preserving all original game functionality.

# 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)
- Main game logic coordinator
- Uses Player, Monster, and DungeonGenerator classes
- Manages game state, FOV calculation, and entity interactions
- Methods: `movePlayer()`, `moveMonster()`, `getState()`, `updateFOV()`
### Supporting Files *(ENHANCED)*
- `user.js` - User management and game instantiation with improved socket ID mapping
- `index.js` - Server entry point with movement throttling, auto-start, and enhanced debugging
- `dbcalls.js` - Database operations
- `rpccalls.js` - Wownero blockchain integration
## Frontend Architecture
### Modular JavaScript Components
#### `ui.js`
- UI utilities and visual helpers
- Functions: `scrollChat()`, `updateBlockHeight()`, `updateFocusIndicator()`
- Manages teletype animations and browser detection
#### `socketHandlers.js` *(MAJOR UPDATES)*
- All WebSocket event handlers with initialization protection
- Events: connect, game_start, game_update, game_over, etc.
- **NEW**: Auto-start functionality for testing (sends "enter" after 500ms)
- **NEW**: `_initialized` flag prevents duplicate handler registration
- **FIXED**: Proper initialization order ensures events are received
- Clean separation of network communication logic
#### `inputHandler.js` *(MAJOR UPDATES)*
- Keyboard and form input management with movement throttling
- **NEW**: 100ms movement cooldown prevents rapid-fire commands
- **NEW**: `_pendingMove` system prevents movement overlap
- **FIXED**: Duplicate event handler prevention
- Handles WASD/arrow key movement, chat input, focus management
- Enhanced debugging with movement timing logs
#### `ui.js`
- UI utilities and visual helpers
- Functions: `scrollChat()`, `updateBlockHeight()`, `updateFocusIndicator()`
- Manages teletype animations and browser detection
#### `game.js` (frontend)
- Core game rendering and client-side state management
- ROT.js display integration, FOV rendering, entity drawing
- Maintained original structure for compatibility
### HTML Structure *(UPDATED)*
- `index.html` - Streamlined main page with proper module initialization order
- **FIXED**: Added missing `SocketHandlers.init()` call to prevent auto-start hanging
- **IMPROVED**: Clean document ready structure ensures proper initialization sequence
- `index_original.html` - Backup of original monolithic structure
## Key Improvements
### Backend Benefits
1. **Modularity**: Clear separation of Player, Monster, and Dungeon logic
2. **Maintainability**: Each class has single responsibility
3. **Testability**: Individual components can be unit tested
4. **Extensibility**: Easy to add new entity types or game mechanics
5. **Movement Validation**: Server-side throttling and validation prevents cheating
6. **Debug Capabilities**: Comprehensive logging for troubleshooting
### Frontend Benefits
1. **Reduced Complexity**: 471-line index.html reduced to ~80 lines
2. **Code Organization**: Related functionality grouped into logical modules
3. **Reusability**: UI and input handlers can be reused/extended
4. **Debugging**: Easier to locate and fix issues in specific modules
5. **Movement Reliability**: Throttling prevents duplicate commands and tile skipping
6. **Auto-Start Testing**: Instant game start for development and testing
