    XML problem, please help :(

    Hi guys,

    I just starded working with AS3 and want to make my personal website with images in background. Now, I'm having one image... but I want to have more images in random order... Maybe my code can help. I tried everything... but I get stucked... I know I should use Math.random, but no progress

    Access of undefined property _id.
    Access of undefined property _id.
    Access of undefined property listLoader.
    Access of undefined property stImage.


    Here is my code:
    XML.ignoreComments = false;
    XML.ignoreProcessingInstructions = false;
    var _xml:XML;
    var _xmlLdr:URLLoader = new URLLoader( new URLRequest("dat/xml/bg.xml") );

    listLoader.addEventListener(Event.COMPLETE, gotList);

    function gotList(evt:Event):void {
    var xmlData:XML = _xml.Data.child("dat");
    var numImages:Number = _id.length();

    var stImage:String = _id[Math.floor(numImages*Math.random())].toString();
    }
    _xmlLdr.load(new URLRequest(stImage));

    Well, like the error messages say, you did not define listLoader or _id. You did define stImage, but you declared it as a local variable in gotList, so it is undefined outside that function.

    I vave tried with this, but still nothing

    Code:
    var _xml:XML;
    var _xmlLdr:URLLoader = new URLLoader();
    _xmlLdr.load(new URLRequest("XML_NOTES.xml"));
    _xmlLdr.addEventListener(Event.COMPLETE, _xmlLded);
    
    function _xmlLded(e:Event):void {
        var loader:URLLoader = e.target as URLLoader;
        _xml = new XML(loader.data);
    }
    function getRandomItem():XML {
        var elementsCount:int = _xml.length();
        var randomIndex:int = Math.floor( Math.random() * (elementsCount-1) );
        return myXML[randomIndex];
    }



    This is my original code, but it is showing only 1 image in background. initFnc is making me so problems


    Code:
    import caurina.transitions.*;
    var mc;
    function _ovrFnc(e:MouseEvent) {
    	Tweener.addTween(e.target, {alpha:0.5, time:0.5});
    }
    function _outFnc(e:MouseEvent) {
    	if (!e.target._mdwn) {
    		Tweener.addTween(e.target, {alpha:1, time:0.5});
    	}
    }
    function _prsFnc(e:MouseEvent) {
    	if (mc!=undefined) {
    		mc.buttonMode=mc.mouseEnabled=true;
    		mc._mdwn=false;
    		Tweener.addTween(mc, {alpha:1, time:0.5});
    	}
    	MovieClip(root)._bgImg._go(_dta[e.target.i]._pth,_dta[e.target.i]._pthx,_dta[e.target.i]._pthxx,_dta[e.target.i]._typ);
    	mc=e.target;
    	mc._mdwn=true;
    	mc.buttonMode=mc.mouseEnabled=false;
    	Tweener.addTween(mc, {alpha:0.5, time:0.5});
    }
    //------------
    var _dta:Array=new Array();
    function _initFnc() {
    	var _id=_xml.Data.child("dat");
    	var _tot:Number=_id.length();
    	for (var i:Number=0; i<_tot; i++) {
    		var _btn:_btnMc=new _btnMc();
    		_btn.x=-(i*14);
    		_btn.y=-11;
    		_btn.i=i;
    		if (i==0) {
    			_btn._mdwn=true;
    			_btn.buttonMode=_btn.mouseEnabled=false;
    			Tweener.addTween(_btn, {alpha:0.5, time:0.5});
    			mc=_btn;
    		} else {
    			_btn._mdwn=false;
    			_btn.buttonMode=_btn.mouseEnabled=true;
    		}
    		addChild(_btn);
    		//-----
    		_btn.addEventListener(MouseEvent.MOUSE_DOWN,_prsFnc);
    		_btn.addEventListener(MouseEvent.MOUSE_OVER, _ovrFnc);
    		_btn.addEventListener(MouseEvent.MOUSE_OUT, _outFnc);
    		//-----
    		_dta.push({_typ:_id[i].@type,_pth:_id[i].@path,_pthx:_id[i].@path2,_pthxx:_id[i].@path3});
    	}
    	MovieClip(root)._bgImg._go(_dta[0]._pth,_dta[0]._pthx,_dta[0]._pthxx,_dta[0]._typ);
    }
    //------------
    XML.ignoreComments = false;
    XML.ignoreProcessingInstructions = false;
    var _xml:XML;
    var _xmlLdr:URLLoader= new URLLoader();
    function _xmlLded(e:Event) {
    	try {
    		_xml = XML(e.target.data);
    		_initFnc();
    	} catch (e:Error) {
    		return;
    	}
    }
    _xmlLdr.addEventListener(Event.COMPLETE,  _xmlLded);
    _xmlLdr.load(new URLRequest("dat/xml/bg.xml"));

    Please format your code with [code] tags. It's pretty unreadable as is.

    In the first code from your last post, myXML is undefined. It looks like you might have meant _xml. Also, you should not subtract 1 from elements count in the random line, since that means that the last element will never be selected.

    In the second, I don't know what you're trying to do. But that's at least partially because you have not provided the XML that's being operated on, the error messages you are receiving, or what _bgImg or _go are.

    Also, what's with all the underscores? Those are some ugly identifiers.

    OK, I have fixed code and this is working with this code

    Code:
    var _xml:XML;
    var _xmlLdr:URLLoader = new URLLoader();
    _xmlLdr.load(new URLRequest("dat/xml/bg.xml"));
    _xmlLdr.addEventListener(Event.COMPLETE, _xmlLded);
    
    function _xmlLded(e:Event):void {
        var loader:URLLoader = e.target as URLLoader;
        _xml = new XML(loader.data);
    	_initFnc();
    }
    function getRandomItem():XML {
        var elementsCount:int = _xml.length();
        var randomIndex:int = Math.floor( Math.random() * (elementsCount) );
        return _xml[randomIndex];
    }
    But it is always showing me only first image :S It is still not random. And my xml is
    Code:
    <DynamicWeb>
    <!--
    	type - static or dynamic
    -->
    	<Data>
    			<dat type="static" path="dat/Images/Bg/001.jpg"/>
    			<dat type="static" path="dat/Images/Bg/002.jpg"/>
    			<dat type="static" path="dat/Images/Bg/003.jpg"/>
    			<dat type="static" path="dat/Images/Bg/004.jpg"/>
    	</Data>
    </DynamicWeb>

    Nothing ever calls getRandomItem.
