I forgot something...true.
Change it to something like:
var scrollRatio = scrollBar.slider._y / scrollBar.scrollTrack._height;
var heightToScroll = currentChild._height -
currentChildContainerMask._height;
if(heightToScroll < 0) {
heightToScroll = 0;
}
currentChild._y = - scrollRatio * heightToScroll;
Where currentChildContainerMask._ height is the height of the Mask that is
masking your currentChild, or simply the height of the outline that is
representing the visible area of your currentChild as its being scrolled.
So basically heightToScroll is equal to the height of your currentChild that
is invisible to the user, it's the part you want to be able to scroll for.
Hope that helps :)

Well, it's giving me more consistant results across my different clips, but
it's
scrolling too far, leaving whitespace at the bottom. Any ideas?
Logically, I think the scrollRatio must be too high, because it's scrolling
further than it should.
I've added an offset because the top of the scrolling area is not the top of
the
screen.
var offset = 108;
var scrollRatio = scrollBar.slider._y / scrollBar.track._height;
currentChild._y = (- scrollRatio * currentChild._height) + offset;
I'll write some code to make the offset dynamic later.
