xpbd collider gen 😄

[shnewto]

hello! this looks like fantastic crate, thanks for all your work on it!

I'm the maintainer of the crate bevy_rapier_collider_gen and I'm starting in on a bit of work to make it an also xpbd collider crate, but my own experience with xpbd is really limited in comparison to rapier and I could use some pointers ❤️ ❤️

I have a draft PR up where I'm tackling things incrementally, the current state is not much more sophisticated than a search and replace bevy_rapier2d with bevy_xpbd_2d and then fixing what the compiler's had to say. But that's gotten me pretty far!

https://github.com/shnewto/bevy_rapier_collider_gen/pull/11

things I could use advice/help on specifically:

• setup / usage in the example. there were some things I needed to do in rapier that I'm not sure yet how to do in xpbd (or if i even need to at all), i.e. .add_plugins(RapierPhysicsPlugin::<NoUserData>::pixels_per_meter(1.0))
• heightfields. i've tried playing with different values for the scalar parameter but i haven't been successful getting it to work for me. any pointers there would be really appreciated

thanks for any guidance you've got to offer!

note about heightfeilds, I was able to get the collider I was looking for using Collider::from(parry::SharedShape::heigtfeild) so no blockers there, would still be curious to know what I'm getting wrong though. thanks for including that advanced strategy section in the docs!

wrt setup/usage the physics could definitely use tuning for the example to be something besides little sprites flying everywhere because their universe's gravity's is confused 😆 but that's not really a blocker for my progress either

@Jondolf thanks for the quick heightfield update! no more questions about how to use!

I went ahead and pulled the trigger on the rename / new crate but made an issue in case anyone's interested in helping tune the xpbd colliders example
