After reading a post on another site about a dearth of "scripted movement" tutorials, I realized how true that observation was. When was the last time you saw a comprehensive tutorial that outlines the basics on how to use programming to move an object across the stage? How about something more complex such as changing directions, varying speed, moving in both x and y directions, and more. This tutorial and a series of subsequent tutorials will explain all this and more.
