Horiz/Vert/Univ Scroller

A Scroll class that supports scrolling of the background of your world. It uses the size of the background image supplied to set the scrolling limits of your world. The methods used for performing the scrolling return any amounts of changes in the scrolling offsets so that actors can be scrolled to those amounts..

It is fairly well documented; at least, to the point where it should be clear as to how to implement the engine into another scenario.

Future update may include a method to scroll the actors as well; however, doing so may make things more complicated than I wanted.

I think that the example of the car traversing 'rugged' terrain is more helpful to me than the scrolling world is, as I am (or was) trying to make a game where I needed that kind of car.

@MatrixWorld : Yes, slow while scrolling. That is because this scrolling engine scrolls the "universal" image, which, because of its size, means a lot of cpu activity. My Scroller class (found by way of my "Scrolling Tutorial" scenario, can be used to scroll only actors, which would pretty much solve that issue. Search "Scrolling Tutorial" to locate.
