bevy_prototype_lyon VS rapier

I am writing a 3D game, and I would like to have a radial (or "pie") menu render over-top the user's current view of the game world. Bevy UI seems exclusive to rectilinear elements, so I have been writing my own using the bevy_prototype_lyon library to draw the annular sector element, and then using bevy UI text nodes to write the text.

You should also check out bevy-prototype-lyon. Very nice to work with

It works rather smooth considering that I didn't put much time into it yet, mostly using bevy_prototype_lyon for the rendering, did create some helping logic to make the entity creating and updating easier to manage (any update to the shapes after creation need to replace it with a new one, so can be quite tedious), also some super basic layouting for grids and docking views.

I use bevy_prototype_lyon to create shapes https://github.com/Nilirad/bevy_prototype_lyon

Ok, so this uses https://rapier.rs/ which is very cool

Rapier, alongside https://nalgebra.org/ (which it uses underneath) has seriously good documentation and some advanced features like cross-platform determinism (something made hard by the way floating point differs between platforms)

Code examples: see examples2d, examples3d-f64 and examples3d directories

What are the pros and cons compared to something like Rapier? When should one use Bevy XPBD instead of Rapier, or vice versa?

Still using Rust in a browser-based multiplayer party game I'm working on! I'm using Actix Web for the backend and rapier2d to handle my game's physics. I'm looking to make some more connections amongst the developer / gaming community through my game down the line.

I have noticed that Rapier 0.17 contains a RopeJoint struct, which constrains maximum distance between two dynamic bodies. It doesn't seem to have found its way into bevy_rapier3d yet so I haven't understood whether it supports (half of) my use case, and looking at the code (https://github.com/dimforge/rapier/blob/master/src/dynamics/joint/rope_joint.rs) I really cannot see how it is actually implemented and how I could extend it to also set a minimum distance, but this may be a place to start.

I was also frustrated with the kcc, so I opened a PR that fixes most of my issues: https://github.com/dimforge/rapier/pull/446

Likewise, see the js bindings of Rapier.

Maybe check out how Rapier does it. Rapier is likely the most advanced physics engine in Rust. (Though Embark Studios is doing some crazy stuff with ML physics.)
