Building a Ping-Pong Game from the model on Raspberry Pi Pico | Implementing Class & State Models
Welcome to the second part of our Ping-Pong game series! In this video, we bring the design to life by implementing the *class and state models* created in the previous tutorial. Using the power of *Object-Oriented Programming* and the **PicoLibrary GitHub repository**, we’ll develop a fully functional Ping-Pong game on the **Raspberry Pi Pico**.
This step-by-step guide walks you through writing Python code to realize the relationships and behaviors we outlined in the design phase. Learn how to utilize pre-built classes and create custom ones to handle game mechanics like paddle movement, ball physics, collision detection, and scoring.

🔑 *What You’ll Learn:*
Translating *UML class and state models* into Python code.
Utilizing classes from the *PicoLibrary* for efficient development.
👉 [PicoLibrary GitHub Repository](https://github.com/jitsengupta/PicoLi...)
Writing custom classes for:
Paddle and Ball behavior
Game Controller logic
Score tracking and game state management
Implementing *state transitions* for gameplay (Start, Playing, Game Over).
Deploying the game to the Raspberry Pi Pico for a live demonstration.
