I have a movieclip that loads dynamic news items from xml data, thus, the \_height of the movieclip is going to be variable. How would I set up a scroll bar that will scroll all the way down to very bottom of the movie clip but not be too short or go to far? I can find the length of the dynamic movie clip by this script: var scrollPaneHeight = (RootNode.childNodes.length) \* 160 160 is the heigth (including seperator) of each news item. For example the movie clip with 4 news items would end up with a \_height of 640. I masked the movie clip and made a scroll bar graphic so the part I am confused on is the scrolling equation. I know how to setDrag and all of that but it seems that my scroll bar either scrolls to far or too short when I change the number of news items. I checked out all the tutorials I could find on kirupa and other sites but they seem way too involved for what I want to do and I wasn’t able to adapt the code. Any help would be appreciated.
