As posted in #announcements I've cut a first release of cljbox2d. This is a library I put a bunch of work in a bit over a year ago, but haven't really touched since then. The story is: my nephew wanted to make a game, so I started teaching him some Clojure and Quil, and started looking into how to add some more game-enginy capabilities to Quil. That's how cljbox2d came about. Then it turned out it had (for reasons) be a browser based game, so I made cljbox2d cljc compatible. In the end we ended up making a point-and-click adventure game, for which you really don't need any physics, and I went with Pixi.js instead, which became another wrapper libary (lambdaisland/puck). But I'm still really happy with cljbox2d, and the API is infintely nicer to deal with than the original (j)box2d.

The point-and-click game became https://invasie-van-de-robots.rocks/

@plexus this is great and works (using clojure2d as a renderer, instead of quil)! One minor request: is to possible to make Vec2 also Seqable (to be able to call seq, first, second on it) not only Indexed?

probably, see https://github.com/lambdaisland/jbox2d . I had to fork jbox2d in order to implement these clojure interfaces, and I don't remember how I did the deploy the clojars 🙈

seems very little has changed upstream at first glance, so that's good

But I can figure that out again, I guess I just used maven directly. PR welcome! see https://github.com/lambdaisland/jbox2d/commit/267c0ea5fe49c78e71735f5be57c34aecbc39c32

Good!

very cool that you got it working with clojure2D as well! if you have a sample (maybe a gist?) it would be great to link to in the README

Sure! I'll push it in 30 minutes (working on pyramid example, just got hit by non seqable vector). It will be a part of clojure2d-examples repo.
