The Scrolling Script

When i make a script i like everything to be centralized in one location. The following script should all go into the container clip's object actions box. Just right click on the "container" clip and go to script.
Here it is your moment of zen...
// ok here is the load event handler
// diff_y is the total amount that the scrollbar can move the
// bound_box is a movie clip that surrounds everything. its just a clear box
// next line we set bounds to the bounding area of the bound_box clip 
// getBounds() returns 4 variable yMin yMax xMin & xMax 
// they are the bounding area that well use for a lot of stuff
// top is the highest amount the scrollbar can go
// bottom is the lowest
// updateScrollbar() is the function for setting the content clip to the right spot
// "scroller._y - top/diff_y" is a percent of the scroll bar's position we multiply it by the amount we can scroll of the content
onClipEvent (load) {
	diff_y = bound_box._height-scroller._height;
	bounds = bound_box.getBounds(this);
	top = bounds.yMin+(scroller._height/2);
	bottom = bounds.yMax-(scroller._height/2);
	function updateScrollbar () {
		content._y = -(((scroller._y-top)/diff_y)*(content._height-bound_box._height));
	}
}
// this detects if you clicked on the scroller it starts a drag with the
// scroller to be from the "top" which we defined earlier to the "bottom"
// we then set scrolling to true
onClipEvent (mouseDown) {
	if (scroller.hitTest(_root._xmouse, _root._ymouse)) {
		startDrag ("scroller", false, scroller._x, top, scroller._x, bottom);
		scrolling = true;
	}
}
// here we stop the drag and set scrolling to false
onClipEvent (mouseUp) {
	stopDrag ();
	scrolling = false;
}
// every frame it sees if your scrolling then it updates the position of the
// content clip by calling out function we made in the load handler
onClipEvent (enterFrame) {
	if (scrolling) {
		updateScrollbar();
	}
}

that code does not include the "throwing" functionality ill add that another day
