I've searched through various tutes on here, and other sites.
I know how to make a background scroll, but wondered what your best / most efficient way of creating one is...?

briefly, I'm using this
code:

bgd._y - vy;


where vy velocity of the backround scroll...

I know its not much harder than that really, but what's the best way to keep your hero centered as well, without lumping your hero and background in one 'world' clip?
