This issue is a declaration that we will add a physics engine eventually. It will not happen soon, but rather slowly over time.

Here are my thoughts:

Yes Mach will provide physics eventually, but no ETA on this yet. I only plan ~2 minor versions (about 1 year) in advance. I will add Physics to the long-term section of the roadmap.

As for what is good today, it depends on what you are making..

3D: ODE is a great 3D physics engine with an official C API, and may be what I would reach for

3D: Bullet Physics is the old tried-and-true, but it is C++ and doesn't have any official C API

3D: Jolt Physics is the up-and-coming contender in the space, but it is C++ and doesn't have a C API. zig-gamedev has bindings to it.

2D: Box2D 3.0 is being worked on these days, which is being written in C instead of C++ like the old version - https://box2d.org/posts/2023/01/starting-box2d-3.0/

My intention is to slowly over time add more collision logic to mach.math and then physics engine logic as well. If you need something immediate which is an extensive/comprehensive physics engine, you'll probably need to pick something above.
