I want to use a for loop to insert a horizontal line of rocks as a border. How can i do this from the world class? I would need to get the actor’s width and height from the world class right? They have to all be at the same height, and right next to each other

Yes. You can get the dimensions of a rock before the loop: 
Actor rock = new Rock();
int wRock = rock.getWidth();
int hRock = rock getHeight();
int y = this.getHeight()-hRock/2;
for (int x=wRock/2; x<this.getWidth(); x+=wRock) {
    addObject(new Rock(), x, y);
}
This should put them along the bottom of the screen as a border.
