Modifiers Signature Description
Methods inherited from class Object
_alpha (MovieClip._alpha property)
public _alpha : Number
The alpha transparency value of the movie clip. Valid values are 0 (fully transparent) to 100
(fully opaque). The default value is 100. Objects in a movie clip with _alpha set to 0 are
active, even though they are invisible. For example, you can still click a button in a movie clip
whose _alpha property is set to 0. To disable the button completely, you can set the movie
clip's _visible property to false.
You can extend the methods and event handlers of the MovieClip class by creating a subclass.
Example
The following code sets the _alpha property of a dynamically created movie clip named
triangle to 50% when the mouse rolls over the movie clip. Add the following ActionScript
to your FLA or AS file:
this.createEmptyMovieClip("triangle", this.getNextHighestDepth());
triangle.beginFill(0x0000FF, 100);
triangle.moveTo(10, 10);
triangle.lineTo(10, 100);
triangle.lineTo(100, 10);
triangle.lineTo(10, 10);
triangle.onRollOver = function() {
this._alpha = 50;
};
