Pong  (YesodScript Tech Demo)

This is a small, complete Pong game as a working showcase of YesodScript: a custom scripting language designed to drive game logic from plain text scripts on top of a very thin C# host layer.

What you can play

• 1 Player: face a simple AI opponent  
• 2 Players: local head-to-head on one keyboard  
• Serve, score, pause, and return to the menu  
• Light "game juice": hit feedback, UI motion, and sound

•   [2]  2 Players
•   [Esc] Quit

In-game

•   Player 1:  W / S
•   Player 2:  Up / Down arrows
•   [Space]  Serve / Confirm
•   [Esc]    Pause

Pause

•   [Esc] Resume
•   [Enter] Quit to Menu

About YesodScript

YesodScript is a lightweight scripting language with its own VM for engine-agnostic projects in C#.

It is also usable as a NuGet package for .NET 8.0 and above (YesodScript.Engine)

This demo shows it handling real game concerns:

• game state and variables  
• control flow (jumps, labels, calls)  
• input branching  
• frame timing and waits  
• rendering hooks (sprites, text, tweens)  
• audio triggers  

Assets and scripts ship beside the executable, so the demo is both a game and a readable example of how the language is meant to be used. You can also fully mod the game without even touching the Github source code or rebuilding the executable.
