I want a hp bar that when the hp percentage level drops the y position of the mask in a movieclip drops so that the health bar decreases verticaly in size. My Hp bar will be, in the final one, a weird shape, not square/rectangle. But the mask seems to stay still. Is this because its inside quite a few movie clips(stage\>health\_orb\>health\>mask)? I’ve seen this sucessfuly working. Anyone got an alternative or soloution. Thanks. If you need the file just ask 😉
