I'm a university student and I have this Assignment where the screen is supposed to go one step down for every 10th ball from the cannon.
It is a clone of the game Puzzle Booble.
public void scrollDown(int fields) { int n = getWorld().getObjects(Actor.class).size(); for(int i=0; i<n; i++) { Actor a = getWorld().getObjects(Actor.class).get(i); a.setLocation(getX(), getY()- fields); } }
