Ok, I don't think I am communicating or/either comprehending correctly... "it needs to be simultaneous just as far as the atom state-change is concerned"
How do I do this? Once the atom is derefenced I would have access to the structures but I need to know how to make sure my code does not sequentially update them one at a time. Obviously, I do not want to write something that updates the enemies and, after the enemies are fully updated, the bullets get updated. I need something that updates enemies while updating the bullets, at the same time. Maybe a code example would help?
