Falling Sand in Java (Swing)

This is a simple "falling sand" simulation written in Java using Swing for the GUI. The project was inspired by the famous YouTube channel "Coding Train", which featured a similar simulation built with a JavaScript graphics library. Unlike the JavaScript version, which could rely on built-in physics and rendering, this Java version required implementing the sand physics logic from scratch.

About

I translated the core ideas from the JavaScript code to Java, and at the time, I was only familiar with Swing for building graphical user interfaces, so that's what I used here.

How it works

• Click or drag the mouse to place colorful sand particles.
• The sand falls and interacts with other particles, simulating gravity and basic physics.
• The simulation runs in real-time with a simple animation loop.

Getting Started

1. Clone or download the repository.
2. Compile the Java files in the src directory.
3. Run the App class to start the simulation.
