494 ActionScript classes
Example
The following example uses
_framesloaded
and
nextFrame()
to load content into a SWF
file. Do not add any code to Frame 1, but add the following ActionScript to Frame 2 of the
Timeline:
if (this._framesloaded >= 3) {
this.nextFrame();
} else {
this.gotoAndPlay(1);
}
Then, add the following code (and the content you want to load) on Frame 3:
stop();

nextFrame function
,
prevFrame function
,
prevFrame (MovieClip.prevFrame
method)
onData (MovieClip.onData handler)
onData = function() {}
Invoked when a movie clip receives data from a MovieClip.loadVariables() or
MovieClip.loadMovie() call. You must define a function that executes when the event handler
is invoked. You can define the function on the Timeline or in a class file that extends the
MovieClip class or is linked to a symbol in the library.
This handler can be used only with movie clips for which you have a symbol in the library
that is associated with a class. If you want an event handler to be invoked when a specific
movie clip receives data, you must use onClipEvent() instead of this handler. The latter
handler is invoked when any movie clip receives data.

Example
The following example illustrates the correct use of
MovieClip.onData()
and
onClipEvent(data)
.
The symbol_mc is a movie clip symbol in the library. It is linked to the MovieClip class. The
first function below is triggered for each instance of symbol_mc when it receives data.
The dynamic_mc is a movie clip that is being loaded with MovieClip.loadMovie(). The code
using dynamic_mc below attempts to call a function when the movie clip is loaded, but it
doesn't work. The loaded SWF file must be a symbol in the library associated with the
MovieClip class.
