Tweening question

when a tween such as this is placed into a frame; does the MC it refers to need to be in the frame or is it called from the libary?

 new Tween(one_mc, "_x", None.easeNone, one_mc._x, 0, 120, false);

If it does need to be placed in the frame, is there a way to avoid this by calling from the libary… via AS?

thanks, i hope i have made myself clear :smiley:
