CollidingEntities not being automatically added

[spectria-limina]

The CollidingEntities component is not being automatically added to my Colliders.

Not sure why; don't have a minimal repro at the moment. Could be that they don't have RigidBody or other physics components?

This is expected behavior after #541, to reduce unnecessary memory usage and iteration. In general, it's not desirable to have CollidingEntities for every single collider, since it's not needed by anything internally, and I imagine in most applications you only need to read it for specific entities anyway.

In Bevy 0.15, this would be elegantly solved with required components. For example, if you wanted every character to have CollidingEntities, you could make it a required component for your Character component.

If you still do want every collider to have CollidingEntities, you can use register_required_components to insert it automatically for colliders.

app.register_required_components::<Collider, CollidingEntities>();

Ah, this is my fault then. Sorry bout that!
