`my_mc``.hitArea`

#### Returns

A reference to a movie clip.

#### Description

Property; designates another movie clip to serve as the hit area for a button movie clip. If the `hitArea` property does not exist or is `null` or `undefined`, the button movie clip itself is used as the hit area. The value of the `hitArea` property may be a reference to a movie clip object.

You can change the `hitArea` property at any time; the modified button movie clip immediately takes on the new hit area behavior. The movie clip designated as the hit area does not need to be visible; its graphical shape, although not visible, is hit-tested. The `hitArea` property can be read out of a prototype object.
