AS3 button firing off multiple times if clicked fast only

ok so, i wrote this code:

import flash.events.Event;
import flash.display.MovieClip;
import flash.display.Loader;
import flash.net.URLRequest;
import flash.events.MouseEvent;
import flash.display.Stage;

stop();

var loader:Loader = new Loader();
var defUrlReq = new URLRequest("indexCoontentLoad.swf");
var urlRequest:URLRequest = new URLRequest();
var myLoadedSwf:MovieClip = null;
var swfStage:Stage = this.stage;

/////////////// INITIATE LOADERS /////////////// 

loader.load(defUrlReq);

/////////////// START MAIN HANDLER FUNCTION ///////////////

/////IMPORT DEFAULT SWF /////
loader.contentLoaderInfo.addEventListener(Event.INIT, loadedHandler);
function loadedHandler(event:Event){  

    myLoadedSwf = event.target.content;
    addChild(myLoadedSwf);

    trace(myLoadedSwf);

    myLoadedSwf.gotoAndPlay("intro");
    trace("STEP 1 -- ext def swf loaded");
}
///////END IMPORT. ///////////////


///// START LISTENERS AND THEIR FUNCTIONS /////

load1.addEventListener(MouseEvent.CLICK,btn4Clicked);
load2.addEventListener(MouseEvent.CLICK,btn4Clicked);
load3.开发者_Go百科addEventListener(MouseEvent.CLICK,btn4Clicked);

///// END LISTENERS /////


///// START FUNCTIONS /////

function btn4Clicked(e:MouseEvent):void { //-- START btn4Loaded
        if (e.target == load1 || e.target == load2 || e.target == load3) {
            myLoadedSwf.gotoAndPlay("outro");

            removeChild(myLoadedSwf);

            urlRequest = new URLRequest(e.target.name+".swf");
            loader.load(urlRequest);
            addChild(myLoadedSwf);
        }

}

and it works, once clicked, it does what it has to do. Ofcourse, me trying to break it, i found that if i click the buttons fast, it will re-import the external swfs causing me to have multiple instances of the external swf.

so in short, if i click like normal(slow ) ie like a person that clicked to view a section etc, then its fine, if i click fast or repeated clicking ie like a person that double clicks etc, then the problem occurs.

any ideas how to fix this?

thanks in advance.

edit*** heres a link to test file to show what i mean http://www.somdowprod.net/4testing/flash/tst

When you set doubleClick to enabled on your movieclip, this will work. The Flash runtime will thencheck for you if it is a double click and only trigger your method once. If you want to listen for the double clicks, you can by changing the event handler.

mySprite.doubleClickEnabled = true;
mySprite.addEventHandler(MouseEvent.CLICK, onClick);

Good luck.

You could try adding a boolean variable that is set to false. Once the .swf is loaded then change that variable to equal true. Then don't let the swf be loaded unless it is set to false. That way it'll only be allowed to be loaded once.

var isLoaded:Boolean = false;
function btn4Loaded(e:Event):void 
{ //-- START btn4Loaded
   if(!isLoaded)
   {
       if (e.target == load1 || e.target == load2) {
            myLoadedSwf.gotoAndPlay("outro");

            removeChild(myLoadedSwf);

            urlRequest = new URLRequest(e.target.name+".swf");
            loader.load(urlRequest);
            addChild(myLoadedSwf);
            isLoaded = false;
        }
    }

} // end btn4Loaded.
