Ok, here is what I have,  
I have a basic square and a wavy line graphic on the stage. Now all I want is to animate a mask unveiling the line. Kinda like the line draws itself. I’m just not sure of how to go about it. I would love to do this with actionscript, but not sure about that either.  
Anyhelp would be greatly appreciated.  
THanks

basically (your ? is kinda vague)::

maskClip is set to mask wavy\_LineStuff ,

maskClip contains shapeClip,

shapeClip is made up of whatever shape you need to define the “reveal” area

shapeClip has the moves built in to it…or it moves within maskClip

…tweens will do it but for more complex activity you’ll need to explore scripted movement
