**([FMX04] problem)**  
Hi,  
I have been messing around with various actionscript I found online for the last week but still can’t seem to get working what i need.

I have two versions at the moment as follows:

1. Flash (with actionscripting) randomly load images from an external XML file.

2. Flash (with actionscripting) passes variables via HTML page to randomly load images.

Number 1 works, number 2 doesnt. The code is pretty similar, however instead of using the XML file I’m trying to pass the variables using flashvars in the HTML code.

## Working version: [http://new.stralia.com.au/bourgies/flash/flash1.html](http://new.stralia.com.au/bourgies/flash/flash1.html) (currently a 20 second delay before change of image) Actionscript from 1:

/_define two arrays, fill the “main” array with the instance names of the moieclips on the stage._/  
xmlData = new XML();  
xmlData.ignoreWhite = true;  
xmlData.onLoad = loadXML;  
xmlData.load(“images.xml”);  
function loadXML(loaded) {  
if (loaded) {  
xmlNode = this.firstChild;  
image = [];  
total = xmlNode.childNodes.length;  
trace(“total=” + total);  
for (i=0; i\<total; i++) {  
image\* = xmlNode.childNodes\*.childNodes[0].firstChild.nodeValue;  
trace(“p=”+(i+1));  
eval(“p”+(i+1)).loadMovie(image\*);  
trace(“image=”+image\*);  
}

main = [p1, p2, p3, p4];  
side = [];  
//define space to keep track of the last visible item.  
nowVisible = {};

//make every mc in the array invisible  
for(var i=1; i\<main.length; i++){  
//main\*.\_visible=false;  
main\*.\_alpha=0;  
}

}  
}

//define a shuffle prototype.  
Array.prototype.skuffle = function(){  
var toReturn = [];  
for(var i=0; i\<this.length; i++){  
Math.round(Math.random()) \> 0 ? toReturn.push(this\*) : toReturn.unshift(this\*);  
}  
return toReturn;  
}

/_Alpha fade prototype_/  
MovieClip.prototype.fadeTo = function(value, speed) {  
this.onEnterFrame = function() {  
this.aV = Math.floor(value-this.\_alpha);  
this.aV ? this.\_alpha += this.aV/speed : (this.\_alpha=value, delete this.onEnterFrame);  
}  
}  
/_define a function to pick the next item from the array & return it,  
filling the side array back up with a different order when it gets emptied._/  
function getNext(){  
side.length \> 0 ? null : side = main.skuffle();  
var toReturn = side.shift();  
return toReturn;  
}  
/_define an interval function_/  
function nextImage(delay){  
trace(“nextimage”);  
//nowVisible.\_visible = false;  
//nowVisible = getNext();  
//nowVisible.\_visible = true;

nowVisible.fadeTo(0,2);  
nowVisible = getNext();  
nowVisible.fadeTo(100,10);

## } //start it up. nextInterval = setInterval(nextImage, 20000);

## images.XML file contents:

## \<?xml version=“1.0” encoding=“utf-8” standalone=“yes”?\> \<images\> \<pic\> \<image\>[http://new.stralia.com.au/bourgies/images/banners/banner\_flashimages.jpg](http://new.stralia.com.au/bourgies/images/banners/banner_flashimages.jpg)\</image\> \</pic\> \<pic\> \<image\>[http://new.stralia.com.au/bourgies/images/banners/banner\_(1)flashimages2.jpg](http://new.stralia.com.au/bourgies/images/banners/banner_(1)flashimages2.jpg)\</image\> \</pic\> \<pic\> \<image\>[http://new.stralia.com.au/bourgies/images/banners/banner\_flashimages3.jpg](http://new.stralia.com.au/bourgies/images/banners/banner_flashimages3.jpg)\</image\> \</pic\> \<pic\> \<image\>[http://new.stralia.com.au/bourgies/images/banners/banner\_flashimages4.png.jpg](http://new.stralia.com.au/bourgies/images/banners/banner_flashimages4.png.jpg)\</image\> \</pic\> \</images\>

Non-working version: [http://new.stralia.com.au/bourgies/flash/flash2.html](http://new.stralia.com.au/bourgies/flash/flash2.html)

Actionscript from 2:  
Using the following flashvars data in the HTML page:  
\<param name=“flashvars” value=“totalimages=4&image1=http://new.stralia.com.au/bourgies/flash/banner\_flashimages.jpg&image2=http://new.stralia.com.au/bourgies/flash/banner\_flashimages2.jpg&image3=http://new.stralia.com.au/bourgies/flash/banner\_flashimages3.jpg&image4=http://new.stralia.com.au/bourgies/flash/banner\_flashimages4.jpg” /\>  
---------------------------------------------------var total = int(totalimages);  
this.totalImages.text = total;  
image = [];  
for (i=1; i\<=total; i++) {  
image\* = eval(“image”+i);  
eval(“p”+i).loadMovie(image\*);  
}  
main = [p1, p2, p3, p4];  
side = [];  
//define space to keep track of the last visible item.  
nowVisible = {};

## //make every mc in the array invisible for(var i=1; i\<main.length; i++){ //main\*.\_visible=false; main\*.\_alpha=0; } //define a shuffle prototype. Array.prototype.skuffle = function(){ var toReturn = []; for(var i=0; i\<this.length; i++){ Math.round(Math.random()) \> 0 ? toReturn.push(this\*) : toReturn.unshift(this\*); } return toReturn; } /_Alpha fade prototype_/ MovieClip.prototype.fadeTo = function(value, speed) { this.onEnterFrame = function() { this.aV = Math.floor(value-this.\_alpha); this.aV ? this.\_alpha += this.aV/speed : (this.\_alpha=value, delete this.onEnterFrame); } } /_define a function to pick the next item from the array & return it, filling the side array back up with a different order when it gets emptied._/ function getNext(){ side.length \> 0 ? null : side = main.skuffle(); var toReturn = side.shift(); return toReturn; } /_define an interval function_/ function nextImage(delay){ trace(“nextimage”); //nowVisible.\_visible = false; //nowVisible = getNext(); //nowVisible.\_visible = true; nowVisible.fadeTo(0,10); nowVisible = getNext(); nowVisible.fadeTo(100,10); } //start it up. nextInterval = setInterval(nextImage, 5000);

Any help would be most appreciated.
