Child mc scale

Hi, I’m trying to figure out a formula/calculation that would keep the scale of a child mc constant(visually) while its parent is scaled. As things sit in flash normally, a child mc inherits the deformations of its parent. So if the parent is scaled to 200%, the child is as well (visually scaled to %200). Thing is, if u check the properties of the child when its parent is scaled, it still thinks it is at %100.

I’m trying to do this so that I can have icons on a zoomable map that stay the same size no matter the zoom level. Tried using localtoglobal, but it suffers from a similar problem.

Any idea what the formula would be?
eg: parent._xscale = 100 / child._xscale=100
parent._xscale = 200 / child._xscale=50

etc –

thanks
