How would one pick every object in a container on-hit? e.g. to flash all of the sprites of a composite object to imply damage.
* Using spriter animations.
* All sprites are members of a container, as automatically created on import.
* Collision box has also been added to said container.
* Collision boxes are also members of a family, which triggers the on-hit event.
So I can pick the collision box on-hit, but how do I get from there to picking all of the sprites in its container and apply some visual effect to them?
