✨ Overview

Pi-Script (Pixel Script) is a lightweight scripting language inspired by Python and implemented in C. It is designed for simplicity, performance, and creative experimentation within a 128×128 pixel virtual environment.

Pi-Script is ideal for:

• 🎓 Educational use
• 🎨 Creative coding
• 🕹 Retro-style graphics experiments
• 🌐 Embeddable web playgrounds
• 🧩 Lightweight scripting integration in C projects

🖥 Pi Shell

<p align=""> <img src="./images/shell.gif" alt="Pi Shell Demo" width="300"/> </p>

Pi Shell is the native desktop runtime environment for Pi-Script.

It provides a lightweight development workflow for running Pi-Script locally with:

• 🧠 Interactive script execution
• 📁 File-based project support
• ⚡ Fast native performance
• 🛠 Integrated graphics window
• 🧩 Ideal for game development and experiments

Run scripts directly:

run <script-name>.pi

Pi Shell extends Pi-Script beyond the browser, turning it into a practical creative coding tool for real desktop development.

🐍 Pi-Script In Action — Snake Game

<p align=""> <img src="./images/snake.gif" alt="Snake Game in Pi-Script" width="300"/> </p>

A complete Snake game built entirely in Pi-Script.

This example demonstrates:

• 🎮 Game loop implementation
• 🕹 Keyboard input handling
• 🧠 State management
• 🎨 Real-time rendering with pixel() and draw()
• ⚡ Smooth performance inside the 128×128 virtual console

The Snake game proves that Pi-Script is capable of building fully playable retro-style games with clean and minimal code.

Try it in (snake.px):

• 🌐 Online Playground
• 🖥 Pi Shell (native build)

🧪 Example

// Pi-Script example
clear(12)

for y in 0..127
    for x in 0..127
        if ((x + y) % 10 == 0)
            pixel(x, y, 6)

draw()
