I am trying to make a sliding menu whose speed is responsive to \_xmouse (slow at the center and fast at the sides…) does it need to exist in two pieces? the problem is that it seems impossible to define 0(zero) as anything but just that… does this make sense to anyone?

if you are trying to make the center 0 but the 0 is located at the top left you could use:
[AS]
center = this.\_width/2;
[/AS]
then calculate speed by finding the distance between the mouse and center ie
[AS]
speed = abs(center-\_xmouse)/10;//less than 10 equals faster
[/AS]
hope that helps,
Shawn
