Tutorial Description - In this tutorial I am hoping (yes hoping) to teach you to do complicated collision. Now this tutorial is teaching advanced detection. If you have never worked with collision detection before I would recommend taking a look at Kirupa's Tutorial. It will get you started on the right track.
Now that you are familiarized with collision detection let's take a look at what this tutorial will help you accomplish.
The purpose of this tutorial is to teach you a slightly different method of collision detection than just simple hitTest. We will use a method that involves outlining the perimeter of an object with many smaller movieclips (the size depends completely on how much detail you desire) and individually checking those clips. You can see that I didn't use very much.
