Click by Click: Loading a Random Flash Movie
See Full Version: This is a shortened click by click version of a: Full Length Tutorial
This tutorial will show you how to load a random Flash Movie onto your web page. Every time a user returns to your page a new Flash Movie will display. This can be used to make your site look fresh and dynamic or to deliver different messages or ads campaigns.
I sometimes use this system to deliver Flash Movies in the head section of the pages in this site. It is very powerful as the same Flash Movie can be used to control all the pages on the site. If I want to change the Flash Movies that are displayed I simply delete my current group of Flash Movies and replace them with the new ones. If I want to change the number of random Flash Movies that are displayed all I need to do is change a single line of ActionScript and upload the new version. That single change may take only a few minutes but it will effect thousands of pages on the webwasp site. There is no need to change any HTML on individual pages.
The ActionScript used in this tutorial is very simple and consists of only four lines. So for those of you wary of ActionScript, don't worry.
For this tutorial you'll be making something like this:
Example: Download the Flash file Beg 042
To change the Movie press your Browser's Refresh button (F5).
Note: I have loaded a series of 6 Flash Movies. The Flash Movies are displayed at random so occasionally the same Flash Movie will be displayed twice in a row. Obviously the more Flash Movies in your series, the less likely they are to repeat.

Step One: Getting the Movies Ready
It is best (although not essential) if your Flash Movies are all the same size. Otherwise you may get some unexpected results.
How Many Movies?
You will need to collect together a number of Movies. How many is up to you. It is even possible to have only 1 and add more at a later date.
You will need to place them all into a single folder on your computer.
Naming the Movies
Name all your Flash Movies numerically from 1. Do not use names like 01.
Step Two: Setting up the Master Flash Document
Step Three: Creating the ActionScript
// Sets the number of Flash Movies in the random sequence
// IMPORTANT: Set this number to how many Flash Movies you have
var myMovieSequence = 6;
// Creates the random number:
var myRandomNumber = Math.floor(Math.random()*myMovieSequence)+1;
// Creates the full Flash Movie name like: 1.swf
var myMovieName = myRandomNumber + ".swf";
// Loads the random Flash Movie:
Important: In Test Mode if you have not saved your Flash file into the same folder as your Flash Movies your movie will not work. When you upload your files to the Internet then the HTML page must be in the same location as the Flash Movies and the location of the Master Flash Movie becomes irrelevant. If you want to use your Flash file in multiple web pages and load Flash Movies form one location you will need to specify an absolute address like this:
var myMovieName = "http://www.yourwebsite.com/movies/" + myRandomNumber + ".swf";
