rapier VS nakama

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.)

To add more detail on the recent work on the ZHeap storage engine. We (Heroic Labs) sponsored work for the Cybertec team to bring it up to date with latest improvements and changes with Postgres' pluggable storage engine:

you can do that, but for what platform? html5? windows? android?, the most easiest way is use firestore a service from firebase (offer a free tier), it is the easiest way not the better, other way is use a service like nakama that is more professional and something in the middle can be mmm pocketbase or supabase.

I recommend the backend solution called Nakama since you’re using Godot: https://heroiclabs.com/

You could create all this yourself, or you can use existing solutions which handle all this (and much more I didn't mention). One that I'm aware of that works with Godot is Nakama. They have a paid hosting option, or you can host the application yourself.

I read using nakama server for this is convinient. https://heroiclabs.com/

Does anyone have recommendations on what to use? I've done a bit of research and found https://heroiclabs.com/. It's a bit unclear to me if it actually supports server side state because it talks about 'hosts' a bit, but I think it does...and it seems like you can host it yourself to avoid the $600 a MONTH! pricetag. But any other recommendations? Has anyone used heroic before?
