👾 Enemy System

• LGBT Enemy Fly: Animated enemy using lgbtbase_1.png and lgbtbase_2.png
• Dual Attack Modes:
  • Charge Attack (Even Scores): Enemy locks onto your position, shows warning line, winds up, then charges at high speed
  • Bullet Attack (Odd Scores): Shoots rainbow bullets that bounce off walls
• Heart Pattern: After charging, enemy flies in a heart-shaped pattern before exiting
• Alternating Sides: Enemy attacks from left and right alternately

🌈 Rainbow Bullet System

• Physics-Based Bouncing: Bullets bounce off walls with realistic physics

👄 Mouth Detection Features

• Bullet Eating: Open your mouth to catch and destroy bullets for +1 bonus point
• Speed Boost: Mouth openness directly controls movement speed (1x - 3x)
• Visual Feedback: Green circle shows mouth detection area when active
• Real-time Display: On-screen speed multiplier indicator

🚀 Performance Optimizations

• GPU Acceleration: OpenCL backend for DNN face detection
• 120 FPS Target: Smooth gameplay on powerful hardware
• Full Resolution Detection: PROCESSING_SCALE = 1.0 for maximum accuracy
• Every-Frame Detection: DETECTION_INTERVAL = 1 for zero lag
• Optimized Collision: Efficient hitbox calculations

🎯 How to Play

Starting the Game

cd src
python main.py

Controls

Action	Control
Move Up/Down	Move your head vertically
Move Left/Right	Move your head horizontally
Speed Boost	Open your mouth wide (up to 3x speed)
Eat Bullets	Open mouth when bullet is near (+1 point)
Toggle Fullscreen	Press F11
Restart Game	Click "Restart" button when game over
Exit	Press ESC or close window

Gameplay Tips

1. Position your face in the center of the camera view
2. Good lighting improves face detection accuracy
3. Open your mouth wide to move faster when dodging
4. Catch bullets with your mouth for bonus points
5. Watch for warnings - red dashed line means charge attack incoming!
6. Odd vs Even scores - Different enemy attack patterns

🎨 Game Mechanics

Enemy AI Behavior

• Score 1+: Enemy activates

• Even Scores (2, 4, 6...):

  1. Enemy enters from side at target height
  2. Shows warning line (1 second)
  3. Winds up (pulls back)
  4. Charges at locked position
  5. Flies heart pattern
  6. Exits to opposite side

• Odd Scores (1, 3, 5...):

  1. Enemy hovers at far edge
  2. Shoots 1 rainbow bullet
  3. Waits 1 second
  4. Slowly exits

Collision System

• Player Hitbox: 50% of sprite size (forgiving)
• Bullet Hitbox: 40% of radius (tight but fair)
• Mouth Eating: 120% of mouth radius (generous)
• Pipe Collision: Pixel-perfect mask detection

Scoring

• Pass Pipe: +1 point
• Eat Bullet: +1 bonus point
• Progressive Difficulty: Pipe speed increases with score

⚙️ Configuration

Edit src/main.py to customize:

# Performance Settings
FPS = 120                    # Target frame rate
PROCESSING_SCALE = 1.0       # Face detection resolution (0.5-1.0)
DETECTION_INTERVAL = 1       # Frames between detection (1-3)

# Gameplay Settings
PIPE_SPEED_BASE = 4          # Initial pipe speed
PIPE_SPACING_FACTOR = 0.1    # Pipe spacing (lower = more space)
BUG_ANIMATION_SPEED = 4      # Wing flapping speed

# Mouth Detection
MOUTH_DARK_THRESHOLD = 70    # Pixel darkness (60-80)
MOUTH_OPEN_RATIO = 0.10      # Openness trigger (0.05-0.20)
BASE_SPEED = 100             # Base movement speed
MAX_SPEED_MULTIPLIER = 3.0   # Max speed boost

🐛 Troubleshooting

Camera Not Working

• Close other apps using the camera (Zoom, Teams, etc.)
• Try changing cv2.CAP_DSHOW to cv2.CAP_ANY in main.py

Low FPS / Laggy

• Lower FPS to 60
• Increase DETECTION_INTERVAL to 2 or 3
• Reduce PROCESSING_SCALE to 0.8

Face Detection Issues

• Improve lighting in your room
• Adjust camera position (face should fill 30-50% of frame)
• Increase confidence threshold in code (line ~354)

Mouth Detection Not Working

• Better lighting on your face
• Adjust MOUTH_DARK_THRESHOLD (try 60 or 80)
• Lower MOUTH_OPEN_RATIO to 0.08
