Step 3: Actionscript explanation.

This is the movieclip event handler. It says anytime this movie clip is on the stage and the mouse moves run the code between the {}.

onClipEvent (mouseMove)

Here I set the values of the two variablesxmousepos1 and ymousepos1. I named those variables in a way that would hopefully make it easy for me and you to track them later on in the actionscipt should something go wrong. I could of named those variables lilsmoochy and misstwiggy if I had wanted, and the code would still work the same. _xmouse and _ymouse are what I call reserved words (from my COBOL programming days), the actionscript reference calls them elements or properties. They hold the value of the x and y coordinates of the mouse, as do my two variables now that I have set them equal to the _xmouse and _ymouse values.

xmousepos1 = _xmouse;
ymousepos1 = _ymouse;

Below I use a conditional statement (if statement) to tell flash to do something if the condition is met. The && is the "and" operator. Meaning ymousepos1>ymousepos2 plus xmousepos1>-347 plus xmousepos1<-282 must ALL be true before executing the below code. Above I tell you what ymouse and xmouse are equal too, so you should be able to see what is going on below.

if (ymousepos1>ymousepos2 && xmousepos1>-347 && xmousepos1<-282)

This is the code used if the above conditional statement is true. _root is a reserved word that tells flash to go to the root level of the movie to retrieve the following. Scrollclip is the name of the movieclip instance we want to target. nextframe() is a action that moves the movie to the next frame and stops. So here we are telling our navigation (scrollclip) to move to the next frame.

_root.scrollclip.nextFrame();

That is the core of the code. There is more actionscript that I did not talk about, but if you understand the code I have talked about up to this point then you should have no problem. The remaining script is nearly the same other than switching the signs around.
