Buoyancy Support

[JackJ30]

Does godot-jolt support buoyancy? I haven't found any reference to it on the readme. Anyone know more about this?
Thank you

No, there's no support for buoyancy right now.

I haven't really looked into what would be required to support this, but from a quick glance it seems like it's just about exposing Jolt's Body::ApplyBuoyancyImpulse method somehow. I'm not entirely sure where you would expose this though, since there's no way to add this to the existing RigidBody3D node, and no way to add "static classes" to serve as helper functions either, as far as I'm aware.

It might be more appropriate to introduce a new type of node, like a JoltFluidVolume3D or something, that does the necessary query every tick to see which bodies it overlaps and applies the buoyancy accordingly.

I'll think about it for a bit, but I can't say if/when it would be implemented.

I have a commit at tjpotts/godot-jolt@60e2720 which implements a JoltBuoyancyRigidBody3D. I'd be happy to submit a PR if this is something you think is worth merging.
