Hi HN,I made crashcat, a lightweight 3D physics library for JavaScript games and creative websites.Existing WASM physics libraries you can find on npm today are performant, but sometimes you just want a little capsule guy to run around on a mesh without downloading a ~3mb WASM file. They often require manual memory management, which feels a bit alien in JavaScript and is easy to mess up.My view on WASM is becoming: go all in, or all out. Having physics state in WASM and game state in JavaScript is an architectural wart. Just build a C++ or Rust engine if you want the best result! But if you want something simple in JS, crashcat can serve that better.Some existing pure JavaScript libraries so

As a business in show hn launch, Crashcat – Lightweight 3D physics for JavaScript is listed here with the public details available about it.

Its current recorded stage is Show HN launch.
