Should we be using Avian instead of Rapier?

[onkoe]

Our project currently uses bevy_rapier3d to provide physics in-game, but lightyear seems to integrate only with the avian crate.

Do y'all strictly recommend using avian with lightyear? Does it provide special functionality, such as lag compensation, automatically with avian when compared to bevy_rapier3d? (I wasn't able to find much documentation on lag compensation - it appears to be usable as a plugin for Avian only!)

Thank you for the incredibly useful project - this project has single-handedly led to rapid development of our FPS game! :)

I am less familiar with rapier so I won't be able to provide an answer.
I've done all my testing with avian because it has a lot of community momentum + all its logic is ECS-based so it's easy to specify custom ordering between lightyear systems and avian systems!

Btw I was working on a FPS prototype here: https://github.com/cBournhonesque/sixdof
but it's not updated to lightyear 0.21

Good luck on your project, keep me posted on discord :)

Will do! Thank you for the fast response!

It appears that some core components of bevy_rapier3d cannot be replicated, so you're limited to spawning them on both the client and server, then hoping each behaves correctly.

I expect to switch to Avian soon to avoid any nonsense in advance. But... I might just stay to see if I can get it working...
