are you looking for a Class or just framescript?

Also, is this for use in Flex or Flash?

and what is your data source you plan on using to hold the values of the image file names? (Web Services, XML, Remoting, Text file, etc)

if you are publishing for Flash Player 9, then you should use the Loader Class...

if you are publishing for version 8, you should use the MovieClipLoader class.

but basically, you start off with an array of your data...

var imgList:Array = new Array();
imgList.push("image1.jpg");
imgList.push("image2.jpg");
imgList.push("image3.jpg");
imgList.push("image4.jpg");
imgList.push("image5.jpg");

then you use the Loader class to pull in the image you want...

but first you need to select a random number from that array...

so you can use this...

var selectedImg:String = imgList( (Math.round(Math.random*5)) - 1 );

(you might check the syntax on that one)

so you have a reference to a random image, and not you just need to use the loader class to pull in that image...

here is a link about the Loader class:

something like this maybe:

function selectImage()
{
      var rn:Number = Math.floor(Math.random()* imgList.length );
      var selectedImg:String = imgList[ rn ];
      // put code here to load the selected image...
}

myButton.addEventListener(MouseEvent.MOUSE_DOWN, selectImage);


 

by: rascalpantsPosted on 2007-07-11 at 12:31:58ID: 19465896

forgot to mention that the posted button code is to be used with this array:

var imgList:Array = new Array();
imgList.push("image1.jpg");
imgList.push("image2.jpg");
imgList.push("image3.jpg");
imgList.push("image4.jpg");
imgList.push("image5.jpg");
