| vertical location of the mouse pointer | read-only |
The floating-point _ymouse property indicates the vertical location of the mouse pointer's hotspot, relative to the coordinate space of mc. If mc is a main movie, _ymouse is measured from the Stage's top edge. If mc is an instance, _ymouse is measured from the instance's registration point. To obtain a consistent _ymouse coordinate that is always measured relative to the Stage, use _root._ymouse.
Placing the following code on a clip causes it to follow the mouse pointer's vertical position, relative to the Stage (the clip moves up and down in a straight line):
onEnterFrame = function () {
this._y = _level0._ymouse;
}
