🎯 Build an AI Shooting Game Using Hand Tracking (Python + OpenCV + MediaPipe)

🎯 Build AI Shooting Game Using Hand Tracking

In this tutorial, we build a real-time AI Shooting Game using Python, OpenCV and MediaPipe. You control the crosshair using your index finger and shoot by pinching your thumb and index finger together.

---

📦 Install Required Libraries

pip install opencv-python mediapipe

---

🧠 How The Game Works

• Camera detects your hand
• Index finger controls crosshair
• Thumb + index pinch triggers shoot
• Flying disc moves across screen
• Hit disc → Score increases
