here is the code from my game so far 
public class Waluigi extends Spieler

    int ySpeed;

Please see my Scroller Class Demos scenario. It has a link to the Scroller class codes used in the demos. There is also my Scrolling Tutorial scenario, if you want to try a build a scrolling system yourself.

The tutorial describes an Actor following type, which can be easily modified to scroll only horizontally. To assist with your codes, you will need to show what you did. You should have an unmodified Scroller class added to your project, a reference to a Scroller object in your scrolling World subclass (with a Scroller object assigned to it);, and an act method in that world that controls what the Scroller object does. Show world class codes for further assistance.
