MovieClip.getBytesTotal()

Availability

Flash Player 5.

Usage

my_mc.getBytesTotal() : Number

Parameters

None.

Returns

An integer indicating the total size, in bytes, of my_mc.

Description

Method; returns the size, in bytes, of the movie clip specified by my_mc. For movie clips that are

external (the root SWF file or a movie clip that is being loaded into a target or a level), the return

value is the size of the SWF file.

You can extend the methods and event handlers of the MovieClip class by creating a subclass. For

more information, see “Assigning a class to a movie clip symbol” in Using ActionScript in Flash.

Example

The following example uses the _framesloaded property to start a SWF file when all the frames

are loaded. If all the frames aren’t loaded, the

_xscale property of the movie clip instance loader

is increased proportionally to create a progress bar.

Enter the following ActionScript in Frame 1 of the Timeline:

var pctLoaded:Number = Math.round(this.getBytesLoaded()/

this.getBytesTotal()*100);

bar_mc._xscale = pctLoaded;

Add the following code to Frame 2:

if (this._framesloaded<this._totalframes) {

this.gotoAndPlay(1);

} else {

this.gotoAndStop(3);

}

Place your content on or after Frame 3. Then add the following code to Frame 3:

stop();
