i have movieclips that i assign y positions for. But not x. They just repel eachother, so i dont tell them to go to a set x position.

I want to make the movieclip rotate to so it points in what ever direction it is going. How can i do this without setting an x ?

i know how to do i using this,

var dx:Number = \_xmouse - mc.\_x;  
var dy:Number = \_ymouse - mc.\_y;  
var angle:Number = Math.atan2(dy, dx);

mc.\_rotation = angle \* 180 / Math.PI;

but as i said, i dont know what its new x will be???
