Appears where? With javascript you generally set up an array of the items to randomize, randomize the array or its counters and then use document.write to write a line or two of html containing the code to do whatever it is you normally would just have html for ex:

<OBJECT CLASSID="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" 
CODEBASE="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0" 
HEIGHT="120" WIDTH="770" ALIGN=""> 
<script type="text/javascript">

swfFiles= new Array()
swfFiles[0]='zap.swf'
swfFiles[1]='golf.swf'
swfFiles[2]='pinball.swf'

function random(n) {
  return Math.floor((Math.random() % 1) * n);
}

Array.prototype.shuffle = function() {var i = this.length;
  while(i--) {this.swap(i, random(i + 1));}
};
Array.prototype.swap = function(x, y) {
  var t = this[x]; this[x] = this[y]; this[y] = t;
};
//End Randomizing Unit

swfFiles.shuffle()

document.write('<param name="movie" value="'+swfFiles[0]+'">'
</script>
<PARAM NAME="quality" VALUE="high">  

<script type="text/javascript">
document.write('<embed src="'+swfFiles[0]+'"')
</script> 
quality="high" 
pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" 
type="application/x-shockwave-flash" 
height="120" width="770"></embed>   
</object>

Put that on your page where normally you would have the plain call for the flash, each time the page loads, it should display a random flash from the array. You can add as many items to the array as you like. Untested (should work though) and could use work to make it degrade well for non javascript enabled browsers.

I have it so there is 10 games per page. I am going to save it as a .js file. Will the code be affected any way?

[jscheuer1]

Well, if you take a look at what I've written, there are two scripts inserted inside of an object element/embed element pair which are mostly just plain HTML. If you use external .js files in place of the two scripts and you know the basics of how to do that, then there should be no problem (assuming the code works as it is now). My advice is to try it out first as written, to see if the concept works. I have some ideas on refining it but, it would be pointless to go ahead unless we get it working 'as is' first. Again, if you think you know what to do, go ahead, enjoy. You are aware that about half of what I wrote is just the plain HTML used to display a flash movie, aren't you? Only the parts that have:

<script type="text/javascript">

</script>

around them are javascript. And, for all I know (I'm not real up on flash yet) you may need a different HTML syntax to call a flash game (as opposed to a movie).

[jscheuer1]

Ok, I wrote one that I know works with flash 'movies'. The first one had a few bugs. If the syntax for a game is different we can change that later. I also added code for non javascript enabled browsers. Its values need to be edited like normal HTML flash tags. In the script, some editing of the parameters (like quality or align) may be needed to suit, others may need to be added for your particular purposes. I really hope you know how to write normal flash HTML object/embed code.

<script type="text/javascript">

swfFiles= new Array()
//Set Flash sources, widths and heights
swfFiles[0]=['zap.swf', 770, 120 ]
swfFiles[1]=['golf.swf', 770, 120 ]
swfFiles[2]=['pinball.swf', 770, 120 ]
