So I am generally new to programming, and understand the tutorial pretty well. I understand the stars and spaceship. The animation part is a little confusing but I'll get to that later.

So I want to make the map on the game many times larger.  The window should stay focused on the ship. This is a start. From here I want to add a minimap, some bad guys (saw a post somewhere about this one), powerups, and whatever else I get to. So my problem is how to draw a larger map.

I opened up cptnruby to see how the map was generated and how the window behaves. I assume its in Map.draw.  I barely understand whats going on here and am hoping for a little more explanation. Some other examples would be much appreciated too if possible.

@height.times do |y|
      @width.times do |x|
        tile = @tiles[x][y]
        if tile
          @tileset[tile].draw(x * 50 - 5, y * 50 - 5, 0)
        end
      end
    end

I get this part. For each tile you loaded form the txt, draw it in the right place. My question here is if this means that each image, in this case Image.load_tiles, has an inherent draw function. Anyways any help would be appreciated. Just try and steer me in the right learning direction.
