Sure! Here's an example of a simple Billiards game implemented as a single HTML file:
This HTML file sets up a canvas element and defines a `Ball` object constructor function. It creates three balls with different positions, sizes, and colors. The balls are animated by updating their positions and redrawing them on the canvas in a loop with an animation frame request. The resulting scene resembles a simple billiards game.
You can save this code in a text file with a `.html` extension and open it in a web browser to play the game. The balls will bounce off the edges of the canvas, giving a basic physics simulation effect.
