Hello everyone,

I've been developing a 2D physics engine for general-purpose use for about three years. Currently, it supports both rigid body and soft body dynamics, and I plan to add fluid dynamics soon. Of course, I also have many improvements and optimizations planned for the future.

Some technical details:

• It uses Verlet integration.
• For BroadPhase, I'm currently using Sweep and Prune (S&P) because I've been very satisfied with its performance. In the future, I plan to combine it with my Spatial Hashing solution.
• For rigid body dynamics, I use a position-based approach, just like in soft body dynamics, rather than an impulse-based one. I also have some promising prototypes that yield better results in terms of stability and performance, and I hope to implement them over time.

Although I'm not an active forum user, as someone who has been interested in physics engines for years, I've found a lot of valuable information and inspiration here. I would have felt uneasy if I hadn't shared this with you, the dedicated game developers.

I welcome all feedback, both positive and negative. Rest assured, I don’t take criticism personally; on the contrary, I see all feedback from fellow game developers as a valuable contribution.

Thank you!
