In this one, I'm going to show you how to decrease the scroll speed and make the scrolling move smoother.
Let's go to our root directory and let's open the index.fla file. Now we open our action script panel (F9) and we go to line 54. The only thing we need to do is decrease that value from 100 to maybe 25. You are free to play.
That's it! Hope it's easy enough! :D
