To quickly convert a coordination in one movieclip to another movieclip, you can use the following function:

import flash.geom.Point;
 
function transCoord(coord:Point, from:MovieClip, to:MovieClip):Void {
        from.localToGlobal(coord);
        to.globalToLocal(coord);
    } 

This can come in handy for example when you need to move a movieclip to another movieclip that is not in the same container mc.
