    myMovieClip._alpha

Description

Property; sets or retrieves the alpha transparency (`value`) of the movie clip specified by `MovieClip`. Valid values are 0 (fully transparent) to 100 (fully opaque). 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 with the `_alpha` property set to 0.

Example

The following statements set the `_alpha` property of a movie clip named `star` to 29.6875% when the button is clicked (there are 128 levels of alpha mapped on a range of 0-100):

    on(release) {
    	star._alpha = 30;
    }
