This is the Pen Version of the Block Scroller... A few people have asked how I did scrolling in Badly drawn racers, here's a very cut down simplistic version of what I do. Press SPACE to show and hide the bars. This time instead of creating clones we're just moving a single sprite around, changing it's costume and stamping it based on the "map" in this case it's the blocks variable. This is probably a simpler method but it means you don't get the hi resolution graphics from using clones. As you can see, when we don't have the bars in place it looks quite bad! And you see the blocks smoothly move left before jumping back to their original position. When they jump back the costume is changed to the next one in the list. By pressing space and showing the bars you can see how the illusion of scrolling occurs. Ask any questions around this if I've not explained things well! Cheers, Rob
