Actionscript 3 Flash ActionScript 3.0卸载SWF

所以我想在加载第二个SWF之前卸载第一个SWF 当我加载SWF时，我的问题是第二个SWF与第一个SWF堆叠 当我从第二个SWF返回到第一个声音播放时，也会叠加 第一个SWF的动画仍然可以在第二个SWF上看到

1.SWF代码：

var pausePoint:Number = 0.00;
var aPlaying:Boolean;
var soundChannel:SoundChannel = new SoundChannel();
var sound:Sound = new Sound(new URLRequest("home.mp3"));

soundChannel = sound.play(0,999);
aPlaying = true;    
    var loader:Loader = new Loader();
    addChild(loader);
    
    btnInfo.addEventListener (MouseEvent.CLICK, loadInfo);
    function loadInfo(event : MouseEvent): void{
        removeChild(loader);
        loader.unloadAndStop();
        var SWFRequestInfo:URLRequest = new URLRequest("2nd.swf");
        loader.load(SWFRequestInfo);
        addChild(loader);
    }

var loader:Loader = new Loader();
addChild(loader);

btnBack.addEventListener (MouseEvent.CLICK, loadBack);
function loadBack(event : MouseEvent): void{
    removeChild(loader);
    loader.unloadAndStop();
    var SWFRequestBack:URLRequest = new URLRequest("1st.swf");
    loader.load(SWFRequestBack);
    addChild(loader);
}

2.SWF代码：

var pausePoint:Number = 0.00;
var aPlaying:Boolean;
var soundChannel:SoundChannel = new SoundChannel();
var sound:Sound = new Sound(new URLRequest("home.mp3"));

soundChannel = sound.play(0,999);
aPlaying = true;    
    var loader:Loader = new Loader();
    addChild(loader);
    
    btnInfo.addEventListener (MouseEvent.CLICK, loadInfo);
    function loadInfo(event : MouseEvent): void{
        removeChild(loader);
        loader.unloadAndStop();
        var SWFRequestInfo:URLRequest = new URLRequest("2nd.swf");
        loader.load(SWFRequestInfo);
        addChild(loader);
    }

var loader:Loader = new Loader();
addChild(loader);

btnBack.addEventListener (MouseEvent.CLICK, loadBack);
function loadBack(event : MouseEvent): void{
    removeChild(loader);
    loader.unloadAndStop();
    var SWFRequestBack:URLRequest = new URLRequest("1st.swf");
    loader.load(SWFRequestBack);
    addChild(loader);
}

有解决这个问题的办法吗

更新2 //main.swf

    const FIRST:int = 1;
const SECOND:int = 2;
var current:int;
var loader1:Loader = new Loader();
var loader2:Loader = new Loader();
addChild(loader1);
addChild(loader2);
addEventListener(LoadEvent.LOAD_SWF, loadSWF);
trace("first Load");
loader2.visible=false;
loader1.visible=false;
loader1.load(new URLRequest("1.swf"));
loader1.visible=true;
current=FIRST;

function loadSWF(event:LoadEvent):void
{
    if(current == FIRST){
        current=SECOND;
        loader2.load(new URLRequest(event.url));
        loader2.visible=true;
        trace("loader2 Loaded");
        loader1.unloadAndStop(true);
        loader1.visible=false;
        trace("loader1 Unloaded");
    }
    else{
        current=FIRST;
        loader1.load(new URLRequest(event.url));
        loader1.visible=true;
        trace("loader1 Loaded");
        loader2.unloadAndStop(true);
        loader2.visible=false;
        trace("loader2 Unloaded");
    }
    
}

1.swf

2.swf

LoadEvent.as

package  {
    import flash.events.Event;  
    public class LoadEvent extends Event {
        
        public static const LOAD_SWF:String = "LoadSWF";
        
        public var url:String;
        
        public function LoadEvent(type:String, url:String,bubbles:Boolean=true, cancelable:Boolean=false) {
            super(type,bubbles,cancelable);
            this.url=url;
        }    
        
        public override function clone():Event
        {
            return new LoadEvent(type,url,bubbles,cancelable );
        }

    }
    
}

制作第三（主）SWF，用于加载/卸载第一和第二SWF。当您单击

btnBack

或

btnInfo

时，您可以发送一些事件。您可以在主SWF中捕获此事件，卸载当前SWF并加载下一个SWF

更新

这是主SWF的代码：

const FIRST:int = 1;
const SECOND:int = 2;
var current:int;

var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadedHandler);
addChild(loader);
loadFirst();

function loadedHandler(event:Event):void
{
    loader.content.addEventListener(Event.CLOSE, closeHandler);
}

function closeHandler(event:Event):void
{
    if (current == FIRST)
    {
        loadSecond();
    }
    else if (current == SECOND)
    {
        loadFirst();
    }
}

function loadFirst():void
{
    if (loader.content)
    {
        loader.unloadAndStop(true);
    }
    current = FIRST;
    loader.load(new URLRequest("1st.swf"));
}

function loadSecond():void
{
    if (loader.content)
    {
        loader.unloadAndStop(true);
    }
    current = SECOND;
    loader.load(new URLRequest("2nd.swf"));
}

下一个代码将从MouseeEvent中的第一个和第二个SWF发送。单击处理程序：

dispatchEvent(new Event(Event.CLOSE));

更新#2

const FIRST:int = 1;
const SECOND:int = 2;
var current:int;

var loader1:Loader = new Loader();
var loader2:Loader = new Loader();
loader1.contentLoaderInfo.addEventListener(Event.COMPLETE, loaded1Handler);
loader2.contentLoaderInfo.addEventListener(Event.COMPLETE, loaded2Handler);
addChild(loader1);
addChild(loader2);

loadFirst();

function loaded1Handler(event:Event):void
{
    loader1.content.addEventListener(Event.CLOSE, closeHandler);
    loader2.visible = false;
}

function loaded2Handler(event:Event):void
{
    loader2.content.addEventListener(Event.CLOSE, closeHandler);
    loader1.visible = false;
}

function closeHandler(event:Event):void
{
    if (current == FIRST)
    {
        loadSecond();
    }
    else if (current == SECOND)
    {
        loadFirst();
    }
}

function loadFirst():void
{
    if (loader1.content)
    {
        loader1.unloadAndStop(true);
    }
    current = FIRST;
    loader1.load(new URLRequest("1.swf"));
    loader1.visible = true;
}

function loadSecond():void
{
    if (loader2.content)
    {
        loader2.unloadAndStop(true);
    }
    current = SECOND;
    loader2.load(new URLRequest("2.swf"));
    loader2.visible = true;
}

更新#3

const FIRST:int = 1;
const SECOND:int = 2;
var current:int;
var loader1:Loader = new Loader();
var loader2:Loader = new Loader();

loader1.contentLoaderInfo.addEventListener(Event.COMPLETE, loader1Compl);
loader2.contentLoaderInfo.addEventListener(Event.COMPLETE, loader2Compl);

addChild(loader1);
addChild(loader2);
addEventListener(LoadEvent.LOAD_SWF, loadSWF);
trace("first Load");
loader2.visible=false;
loader1.visible=false;
loader1.load(new URLRequest("1.swf"));
loader1.visible=true;
current=FIRST;

function loader1Compl(event:Event):void
{
    loader2.unloadAndStop(true);
    loader2.visible=false;
    trace("loader2 Unloaded");
}

function loader2Compl(event:Event):void
{
    loader1.unloadAndStop(true);
    loader1.visible=false;
    trace("loader1 Unloaded");
}

function loadSWF(event:LoadEvent):void
{
    if(current == FIRST){
        current=SECOND;
        loader2.load(new URLRequest(event.url));
        loader2.visible=true;
        trace("loader2 Loaded");

    }
    else{
        current=FIRST;
        loader1.load(new URLRequest(event.url));
        loader1.visible=true;
        trace("loader1 Loaded");
    }

}

你能给我一些简单的代码让事件监听器卸载当前的SWF吗？很抱歉，响应太晚了，我仍然不知道如何在子SWF运行时通过单击子SWF上的按钮来运行主函数？在子SWF

dispatchEvent（new event（event.CLOSE））中调度事件。接下来，在主SWF
loader.content.addEventListener（event.CLOSE，closeHandler）中捕获该事件。您知道用参数加载dispatchEvent（）的方法吗。。如果我想运行许多SWFYE，我想我需要参数。使用自定义事件。
