Preloading Shared Libraries - Page 4

Large shared libraries 2

Because of the library being loaded as if it were part of the presentation, we can also check if it is downloaded completely or not using preload functionality.

Here's how to set up myLibrary.swf.

In the actions layer on frame 5 add the following code:

/* check if this file is downloaded completely
compare the filesize with the amount of loaded bytes*/

if (this.getBytesTotal() == this.getBytesLoaded() ){
	// when loaded
	//tell myMovie.swf to play
	_level0.play()
	//goto empty frame
	gotoAndStop("empty");
}else{
	//go back to frame 1 if not loaded completely yet
	gotoAndPlay("start")
}

This is basic preloading functionality. It'll check if myLibrary.swf is completely downloaded using getBytes functions. If it is.. it'll tell myMovie.swf to continue (by calling _level0.play()) and tell itself to go to an empty frame.. If it is still downloading, the movie will jumpback to the frame named 'start' (which is the first frame) and play again.
