randomly looping swf files continuously

Recommended Posts

Hi - I'm new to using greensock (and actionscript) and am trying to play around with some code I found. It originally loaded several swf files and looped through them continuously  - I'm trying to randomize it.  I have created an array and added code to shuffle through the array, but I'm stuck trying to integrate it into the looping files.  I'm pretty sure I have to do something with the loaderIndex, but I'm not sure what.

 

Any help would be great - thanks.

 

Code:

 

progress_mc.scaleX = 0;

var loaderIndex:Number = -1;
var currentLoader:SWFLoader;
var urls:Array = ["SWF0.swf","SWF1.swf","SWF2.swf"];
var swfs:LoaderMax = new LoaderMax({onComplete:completeHandler,onProgress:progressHandler,onChildComplete:childCompleteHandler});

// Loop through urls and create a queue of swf loaders
for (var i:Number = 0; i < urls.length; i++)
{
    swfs.append( new SWFLoader(urls, {container:container_mc, autoPlay:false}) );
}
urls.sort(randomSort);


function randomSort(a:*, b:*):Number
{
    if (Math.random() < 0.5)
    {
        return -1;
    }
    else
    {
        return 1;
    }
}

function progressHandler(e:LoaderEvent):void
{
    progress_mc.scaleX = e.target.progress;
}

function childCompleteHandler(e:LoaderEvent):void
{
    trace(e.target + " loaded");
    e.target.content.visible = false;
}

function completeHandler(e:LoaderEvent):void
{
    trace("all swfs loaded");

    progress_mc.visible = false;

    initCurrentLoader();
    addEventListener(Event.ENTER_FRAME, trackSWFPlayback);
}


function initCurrentLoader()
{
    loaderIndex++;

    if (loaderIndex == swfs.numChildren)
    {
        //reset back to 0 if the last swf has already played
        loaderIndex = 0;
    }

    //dynamically reference current loader based on value of loaderIndex
    currentLoader = swfs.getChildAt(loaderIndex);

    //make the content of the current loader visible
    currentLoader.content.visible = true;

    //tell the current loader's swf to to play
    currentLoader.rawContent.gotoAndPlay(1);
}

function trackSWFPlayback(e:Event):void
{
    //trace(currentLoader.rawContent.currentFrame);
    //detect if the loaded swf is on the last frame
    if (currentLoader.rawContent.currentFrame == currentLoader.rawContent.totalFrames)
    {
        trace("swf done");
        //hide and stop current swf
        currentLoader.content.visible = false;
        currentLoader.rawContent.stop();
        //set up and play the next swf;
        initCurrentLoader();
    }
}

load_btn.addEventListener(MouseEvent.CLICK, loadSWFs);

function loadSWFs(e:MouseEvent):void
{
    load_btn.visible = false;
    swfs.load();
}

Have you tried sorting the urls before creating the loaders and appending them to the LoaderMax?

urls.sort(randomSort); // do this first

// Loop through urls and create a queue of swf loaders
for (var i:Number = 0; i < urls.length; i++)
{
    swfs.append( new SWFLoader(urls[i], {container:container_mc, autoPlay:false}) );
}

Hi - thanks, yes that did help loop the files, but didn't quite achieve what I wanted, and now I look at the code I realise I'm tackling what I want to do the wrong way, so I'm going back to the drawing board!
