LoaderClassAlternate

Package:
Class:
Inheritance:
biz.flashscript.utils
public class LoaderClassAlternate
Sprite
The LoaderClassAlternate class allows loading movies and bitmaps, all objects usually loaded with the Loader class. The difference to other loader classes is that two Loader objects are created, which allow overlapping animations. Use the constructor new LoaderClassAlternate() to create a new LoaderClassAlternate object and add parameters as desired.

public function initLoader(myURL:String, loadFinished:Function, myTarget1:Object, myTarget2:Object)

Parameters

  • myURL:String ____ The url for the object to load.
  • loadFinished:Function ____ The name of the function for the completed event.
  • myTarget1:Object ____ One of the Loader objects ("urlLoader1").
  • myTarget2:Object ____ The second of the Loader objects ("urlLoader2").
progressLoader ():void  method
public function initLoader(myURL:String, loadFinished:Function, myTarget:Object)

  • myURL:String ____ The url for the object to load.
  • loadFinished:Function ____ The name of the function for the completed event.
  • myTarget:Object ____ The Loader object to do something with.
Examples
Create a new fla file and name it LoaderClassAlternExample.fla. Place the fla in the same folder as the biz folder. Put a Button component on the stage and delete it. Have two images of your choice ready. Then create an Actionscript file, name it LoaderClassAlternExample.as and place this script.
