That's what shirokuma is trying to tell you there are tutorials which have that very feature in them so if you take a look at them you can see how they are done.
Are you looking for something like this? (I have a little error in there somewhere so the blocks don't seem to be lining up perfectly, but I don't want to spend anymore time on it in case it's not what you're looking for.)
