Watch and be amazed at my awesomeness :P
I made a scrolling background. But this one doesn't use clones or pen, this uses the mosaic effect to turn one costume into many! You can see that by pressing the stop sign. The sprite will turn back into one BIG version of the same thing. :) You can use this without credit! Go inside and backpack the sprite! All that I ask is that you tell me if you use it so that I know :) If I forgot to explain something or you want a better explanation, (I don't know if I can help with that, but I will try my best) please tell me. How it works: The code first needs to know the dimentions of the costume. It then takes those dimentions and figures out how many of itself across it will take to cover the whole screen at once. The mosaic effect is used to turn the sprite into the number of itself required. Lastly, since there is now a lot of tiny versions of the original, the sprite gets very big to make the small ones the same size as it was at the beginning. And tada! Now you have a scrolling background with just ONE costume and no pen or clones!
