Currently to make levels I make images by pixel with color coordinated sprites to go along with it.

    int w = image.getWidth();

    int h = image.getHeight();

    for(int xx = 0; xx < w; xx++){

        for(int yy = 0; yy < h; yy++){

            int pixel = image.getRGB(xx, yy);

            int red = (pixel >> 16) & 0xff;

            int green = (pixel >> 8) & 0xff;

            int blue = (pixel) & 0xff;



            if(red == 255){

                handler.add_entity(new Box(xx * 32, yy * 32, 32));

            }

            if(blue == 255){

                handler.add_entity(new Box(xx * 32, yy * 32, 32));

            }

            if(green == 255){

                handler.add_entity(new Box(xx * 32, yy * 32, 32));

            }

            if(red == 0 && blue == 0 && green == 0){

                handler.add_entity(new Box(xx * 32, yy * 32, 32));

            }



        }

    }

But I ended up wanting to make a Binding of Issac style of dungeon generation with the same method, so I ended up making a seed generator that makes a seed such as "B-184923" which all refer to file names, "B" being a layout of rooms and a number being a room to be placed in the layout spots which are the green boxes.

What would be the best way to place the rooms (that are determined by color) in a pattern that refers to a file like the system I tried.
