There are several scrolling worlds, look at danpost's Scrolling Super World or Busch2207's ScrollWorld .

You can use 'setLocation' using negative coordinate values after adding it to the world. And if you want the starting screen to still show it, add a 'super.act();' statement immediate after resetting its location.

So would it be like addObject(new Actor(), 25, 25); then in the Actors constructor setLocation(-300,-300);

No. You cannot set the location of an actor in its constructor. The actor is not considered created until the constructor has completed and the actor cannot be placed into the world until the actor has been created. You would follow your 'addObject' line with the 'setLocation' line, one right after the other. But in order to do that, you will need a reference to the actor being created. The following breaks up your 'addObject' line to acquire a reference:

Actually, there is a 'fillScrollingBackground' method that will do that for you.

With the scrolling world, if you were to break it up into a graph how would it be displayed. I mean like if u wanted a building in the top right of the scrolling world,not the viewable world what would be the coordinates. Its a 1,000 x 1,000 px wide scrolling world with a viewable area of 450 x 400

If your scrolling area was 1.000 x 1.000, then your main actor would spawn at (500, 500) in scrolling coordinates; which is equivalent to (225, 200) in viewable coordinates. The difference in these coordinates is what you would subtract from scrolling coordinates to get world coordinates Spawning an object at (750, 100) in scrolling coordinates would be placed at (475, -200) in world coordinates.

For any (scrollingX, scrollingY), the world coordinates would be (scrollingX-(1000-450)/2, scrollingY-(1000-400)/2) or (scrollingX-275, scrollingY-300). (0, 0) would then be (-275, -300) in world coordinates.
