The ability to perform a physics spherecast instead of just a raycast.

This is a very useful method to as it avoids needing multiple ray casts to check bounding boxe, that still end up less complete.

Could be implemented something like this

Other cast shapes would be nice, but might be costly and complex, cast sphere is generally cheaper and simple afaik.

So a more comprehensive and expandable version might be

If the latter aproach was taken more shape types could be added later, so more complex but maybe more future proof.
