FMX Scripted masks...need advice and help

Hi everyone. So I have a client who is IN LOVE with this site:

http://www.palazzoversace.com/

(intro is terribly long).

I was just getting ready to start tweening and wondered if there’s a way to script masks to do the same thing easily…NOT on mouse drag, but on the click of the button. I found a nice tutorial which will make a similar thing happen when you drag the mouse. But when I tried to target x and y the whole thing fell apart.

I’m fairly new to AS, but I’m more than willing to give it the ol’ college try if it’ll keep my file size down.

Any help/advice would be greatly appreciated. Told the client I’d ask around and get back to them.

Thanks!
