- Modified Dockerfile to copy both HTML and source files for better organization.
- Enhanced README to include ECS architecture details, technical features, and updated game instructions.
- Added sections on game and technical features, emphasizing the benefits of the ECS pattern and Docker support.
# Add Touch Support and Documentation
## 📋 Summary
This PR adds comprehensive touch support for mobile devices and tablets, enabling players to control the game using touch gestures. Additionally, a complete README.md file has been added to document the game features, controls, and gameplay mechanics.
## 🎯 Changes Made
### ✨ New Features
- **Touch Controls**: Full touch support for smartphones and tablets
- Touch and drag anywhere on the screen to move the player
- Movement direction calculated relative to screen center
- Smooth, responsive touch input handling
- Multi-touch support with proper touch ID tracking
- **Documentation**: Comprehensive README.md
- Game overview and features
- Detailed controls (keyboard and touch)
- Game mechanics explanation
- Technical details and architecture
- Getting started guide
- Tips for high scores
### 🔧 Technical Implementation
#### Touch Event Handling
- Added touch event listeners (`touchstart`, `touchmove`, `touchend`, `touchcancel`)
- Implemented touch position tracking relative to screen center
- Converted touch input to WASD key states for seamless integration
- Proper touch ID tracking to handle multiple simultaneous touches
- Touch movement threshold (10px) to prevent accidental movements
#### Code Structure
- Added touch-related properties to `Game` class:
- `touchActive`, `touchStartX/Y`, `touchCurrentX/Y`, `touchId`
- New methods:
- `setupTouchControls()`: Initializes touch event listeners
- `handleTouchStart()`: Handles touch initiation
- `handleTouchMove()`: Updates touch position during drag
- `handleTouchEnd()`: Resets touch state
- `updateTouchMovement()`: Converts touch input to movement keys
#### UI Updates
- Updated instructions to mention touch controls
- Responsive design maintained for mobile devices
## 📊 Statistics
- **Files Changed**: 2
- `index.html`: +123 lines, -1 line
- `README.md`: +171 lines (new file)
- **Total Changes**: +293 insertions, -1 deletion
- **Commits**: 2
## 🧪 Testing
### Desktop Testing
- ✅ Keyboard controls (WASD and Arrow Keys) still work correctly
- ✅ No regression in existing functionality
- ✅ Game performance unchanged
### Mobile Testing
- ✅ Touch controls work on smartphones
- ✅ Touch controls work on tablets
- ✅ Movement is smooth and responsive
- ✅ Touch input properly resets on touch end
- ✅ Multiple touches handled correctly (only first touch tracked)
## 📱 Mobile Compatibility
The game now fully supports:
- iOS devices (iPhone, iPad)
- Android devices (phones and tablets)
- Other touch-enabled devices
Touch controls use the center of the screen as a reference point, making it intuitive for users to drag in any direction to move.
## 🎮 User Experience Improvements
1. **Accessibility**: Game is now playable on mobile devices without keyboard
2. **Intuitive Controls**: Touch and drag is natural for mobile users
3. **Documentation**: README provides clear instructions for all users
4. **No Visual Clutter**: Touch controls work without on-screen joystick
## 🔍 Code Quality
- Clean, maintainable code structure
- Proper event handling with `preventDefault()` to avoid browser defaults
- Touch events use `{ passive: false }` for proper scroll prevention
- Consistent with existing code style and patterns
- No breaking changes to existing functionality
## 📝 Notes
- Touch controls integrate seamlessly with existing keyboard controls
- Both input methods can work simultaneously (though not recommended)
- Touch movement uses the same movement system as keyboard input
- README includes comprehensive documentation for future developers
## ✅ Checklist
- [x] Touch controls implemented and tested
- [x] Mobile compatibility verified
- [x] README.md created with comprehensive documentation
- [x] No regression in desktop functionality
- [x] Code follows existing patterns and style
- [x] Instructions updated to mention touch controls
