I'm using the stage object to align multiple MC's. My question is how do I affect a MC's position if I want to have it be centered on both axis but 100px away from the bottom margin instead of the top relative to the size of the window?

here's my positioning code:

code:

navBar._y = Stage.height;
navBar._x = Stage.width/2;
tpShadow._x = Stage.width/2;
tpShadow._y = 6;
idol2._y = Stage.height/2;
idol2._x = Stage.width/2;




Also if i'm using an empty MC to load external swf's, do the external swf's have to have AS for positioning as well or do I position the empty MC in the base movie?

Thanks,

Nick
