GameScroll is a library|system to make game with scroll in a easy way. It adds a lot of functionality and functions specially to make easier the developing of games and other stuff.

GameScroll SVN repository

Using GameScroll, you create a scroll (or various), then you and “views” (Regions) to display it on the screen. ONE scroll, multiple views. Think in a Regions as a windows through you see a piece of the map.

GameScroll work with two regions, one knows as “Display Region”(DR), the other as “Move Region”(MR) and a “camera”. MR is inside DR. You can move the camera inside the move region without moving the scroll, when the camera is out of the move region, the scroll move to fit it inside, else if you have reached a map border.

You could also put various Regions working on the same “scroll”, for example for a 2Players-game. See an example of a screen:
