在Flash（AS3）中使用“加载程序”加载其他SWF文件后，删除SWF文件

Question

I am trying to load multiple swf files. But the problem is that whenever I load them (back and forth; vice-versa), my file keeps on slowing down. I looked a solution from the internet, such as using "unload" and "removeChild" but I can't get a clear solution and I don't know where to put it. Any help is very much appreciated..Here's my code on how I load my swfs:

MainMenu.swf:

//***************CLICK GALLERY*********************//
Gallery_btn.addEventListener(MouseEvent.CLICK, Gallery);

function Gallery(event:MouseEvent):void{

    var ldr1:Loader=new Loader();
    ldr1.load(new URLRequest("Gallery.swf"));
    addChild(ldr1);

}

Gallery.swf:

//***************CLICK QUIT******************//
Quit_btn.addEventListener(MouseEvent.CLICK, Quit);

function Quit(event:MouseEvent):void{

    var ldr1:Loader=new Loader();
    ldr1.load(new URLRequest("MainMenu.swf"));
    addChild(ldr1);
}

Answer 1

You need to use removeChild and remove every listener. You can unload swf by calling unload on your loader or unloadAndStop.
