Verlet Integration is a physics simulation method commonly used for soft-body dynamics, ropes, and cloth simulation. I implemented this technique in GameMaker by developing a 2D physics library that simplifies setting up these simulations. The library includes expandable classes for basic objects, helper classes for force fields and connectors, an example implementation, and a wireframe mode for debugging. By chaining multiple simulated objects together, it’s possible to create dynamic and visually interesting structures for decoration or gameplay features.

I originally developed this library as part of a small game project but later decided to release it publicly on itch.io, where it gained significant popularity. Seeing interest from other developers, I refactored the code to improve its structure, readability, and maintainability while also adding better documentation and examples. The updated library now includes helper functions for features like force fields and textured cloth / ropes, making it more versatile and user-friendly. To encourage collaboration and further improvements, I made the project open-source on GitHub, allowing anyone to contribute and expand upon it.

I included this project to showcase how I approach developing an open-source library for other developers. It follows a clear structure, is well-documented, and comes with an example implementation.
