The #gamedev world now has a new FREE & open source 3D physics engine... Box3D.
It's from Erin Catto, creator of Box2D, it's light weight C, portable and feature rich and already being used in the S&Box engine.

New recording and replay feature added to Box2D. Uses determinism to exactly reproduce the simulation for your game. Debug your game with all details including ray casts and other queries. Deterministic rollback too.

Replay
Replay is a new system I developed for Box2D. The main goal is to allow users to send me files I can use to reproduce bugs. Because Box2D is open source, I can rarely run a user’s game or see their co...

We've added 2 new Box2D scripting examples! ⚙️
🟢 Box2D Sensor Toggle - useful for dynamic trigger/collision behavior
↔️ Box2D Prismatic Joint - useful for controlled linear movement along an axis

Wow, I love Dart's native assets feature! 💙
I just finished completely rewriting Forge2D from being a Dart port of Box2D to embedding Box2D v3 directly instead (wasm for web). It's about 20x more efficient now and we can easily stay up to date with new Box2D updates. 🔥

time to stop being a pussy myself. im gonna attempt writing my own 2d physics engine
"but mores you can use box2d with gamemaker" yeah except gamemaker's implementation is kind of limited. i want FULL control. and for that, i have to get balls deep myself

i lowkey miss the era when indie games were all experimenting with physics and shit. newer indie games don't have the balls to let the janky physics engine take the control. pussies

Fast CCD without ghost collisions (Box2D-inspired) by Jondolf · Pull Request #996 · avianphysics/avian
Objective
Fixes #990.
Currently, Avian relies heavily on Bepu-style speculative collision with an unbounded speculative margin. This has two major problems:

Do you need slippery ice, bouncy rubber, heavy stone, or sticky mud in your physics game?
Or maybe a bridge, chain, trap, or rope, made from bodies connected with revolute joints?
We’ve added two new Box2D scripting examples for Defold!
