Is there an API to query all entities around a position in special radius?

I'm learning ECS. And need query all other entities around target entity.

Through loop all entities and check their position is in the circle or not, which can work. But if there exist API, I think that will be better.

Thanks.

Someone correct me if I'm wrong, but I don't think such an API exists. You might be interested in this, though: https://github.com/laundmo/bevy-spatial

I'm doing that with rstar, maintaining list of entities and their positions in a separate rtree.

Thank you.
