I've taken an interest in 2d physics engines after working on multiple Unity 2d platformers, so I decided to make my own physics engine! I already have a sweet spot for Pixijs as a rendering engine, since I made my first few jam games with it. At heart, it's not a framework, so I wanted to contribute to it by making a plugin that works seemlessly and does all you want a 2d physics engine to do.

I know a few integrations of pre-existing 2d physics engines have already been done with PixiJS, like Matterjs and Box2D, but I don't like the idea of having to sync the renderer and the physics simulation. Making the physics use PixiJS's DisplayObject transform is a lot more intuitive overall, and avoids problems where the 2 are out of sync, while also probably being faster and more memory efficient (don't quote me, I didn't benchmark it).

There are also a few things I'm unhappy about, like those engines not being maintained and Matter.js's circles not being real circles, but overall it's mainly just an excuse to program something myself for funsies.
