While i was doing a little AS2.0 project i made this MultiImageLoader class.
This class will load multiple images for you and it will dispatch events.
*NOTE: This class uses the EventDelegate from the asapframework.
———-
USAGE:
var multi:MultiImageLoader = MultiImageLoader.getInstance();
multi.addEventListener( MultiImageLoader.IMAGE_START , onImageStart );
multi.addEventListener( MultiImageLoader.IMAGE_PROGRESS , onImageProgress );
multi.addEventListener( MultiImageLoader.IMAGE_COMPLETE , onImageComplete );
multi.addEventListener( MultiImageLoader.MULTILOADER_COMPLETE, onMultiComplete );
multi.store( “img/img_01.png”, photoContainer_01 ); //Image address and image holder.
multi.store( “img/img_02.png”, photoContainer_02 );
multi.store( “img/img_03.png”, photoContainer_03 );
multi.startLoad();
Events:
- MultiImageLoader.IMAGE_START ;
- MultiImageLoader.IMAGE_PROGRESS ;
- MultiImageLoader.IMAGE_COMPLETE ;
- MultiImageLoader.MULTI_START ;
- MultiImageLoader.MULTI_COMPLETE ;
