Controlling ActionScript 3.0 movie clips
Each MovieClip object has a timeline, and also includes properties and methods for
controlling the playhead and working with frames and scenes.
Many properties and methods of the ActionScript 1.0 and 2.0 MovieClip class are present as
properties or methods of the ActionScript 3.0 MovieClip class. Some are inherited from a
superclass. For example, the
name a few, are valid for the MovieClip class because it extends the DisplayObject class.
However, some properties that had names that begin with the underscore character, such as
, , , have been renamed without the underscore in ActionScript 3.0. Also, the
_x _y _root
, ,
_xmouse _xscale _ymouse
, and .
mouseY scaleY
The MovieClip class includes methods and properties for controlling the movie clip. The
following properties let you monitor the total number of frames and scenes in a movie clip
and monitor information about the frame and scene at the current playhead position:
,
currentFrame currentLabel
The following methods let you control the playhead for the movie clip:
,
gotoAndStop() nextFrame()
.
stop()
For example, the following code moves the playhead to the first frame of the current scene of
the MovieClip object:
myMovie
myMovie.gotoAndPlay(0);
For more information on these and other properties and methods, see the MovieClip section
of the ActionScript 3.0 Language Reference.
You can set the frame rate for all movie clips in an application using the
of the Stage object.
In contrast to ActionScript 1.0 and 2.0, a loaded SWF file in ActionScript 3.0 can be a
MovieClip object, an AVM1Movie object, or a Sprite object. However, in ActionScript 3.0
you can control the timeline only of a MovieClip object. Sprite and AVM1Movie objects do
not include timeline-related methods and properties.
