public _yscale : Number

Sets the vertical scale (percentage) of the movie clip as applied from the registration point of the movie clip. The default registration point is (0,0).

Scaling the local coordinate system affects the _x and _y property settings, which are defined in whole pixels. For example, if the parent movie clip is scaled to 50%, you set the _x property to move an object in the movie clip by half the number of pixels that it would if the movie were at 100%.

Example

The following example creates a movie clip at runtime called box_mc. The Drawing API is used to draw a box in this instance, and when the mouse rolls over the box, horizontal and vertical scaling is applied to the movie clip. When the mouse rolls off the instance, it returns to the previous scaling.

this.createEmptyMovieClip("box_mc", 1);
box_mc._x = 100;
box_mc._y = 100;
with (box_mc) {
    lineStyle(1, 0xCCCCCC);
    beginFill(0xEEEEEE);
    moveTo(0, 0);
    lineTo(80, 0);
    lineTo(80, 60);
    lineTo(0, 60);
    lineTo(0, 0);
    endFill();
};
box_mc.onRollOver = function() {
    this._x -= this._width/2;
    this._y -= this._height/2;
    this._xscale = 200;
    this._yscale = 200;
};
box_mc.onRollOut = function() {
    this._xscale = 100;
    this._yscale = 100;
    this._x += this._width/2;
    this._y += this._height/2;
};
