ActionScript 3.0 :: Detect URLRequest Variable Change?
Nov 21, 2009
I'm using AS3 to get variables from a plain text file. The variables are loaded, and assigned as a variable in Flash.
Code:
var checkNew:Timer = new Timer(2000);
checkNew.addEventListener(TimerEvent.TIMER, reConnect);
checkNew.start();
[Code].....
So basically as you can see here, the gamertag is loaded from a plain text PHP file and converted into a variable. What I need to be able to do is tell whether or not that variable has changed (ex. 1 changed to 2).

I this code a setup a button that calls a url request from another variable and that works fine:
var venue_www:String = "http://www....1";
var venue_url:URLRequest = new URLRequest(venue_www);
function venue_Click(event:MouseEvent):void {
navigateToURL(venue_url);
vInfo.highlight1.alpha = 1;
} vInfo.venue.addEventListener(MouseEvent.CLICK, venue_Click);
But later on I have a function that changes the venue_www variable among other details. But my button won't update with the new url variable. I've actually also already removed the event listener and re-added it through the script, for whatever its worth.
function setInfo1() {// one for each venue
if (currentVenue=="ATL") {
venue_www = "http://www.....2";
}}

I have a flash movie being loaded inside a parent movie. Inside the loaded movie is a variable called lvl, and its refered to as loadedmovie.lvl in the parent movie.
So if i'm wondering what the lvl is in the loaded movie, I just use loadedmovie.lvl to get the variable.
But I want to know when this variable CHANGES. How am I able to detect when this lvl variable changes? Inside the loaded movie, it's been set to change almost every frame in the movie, but I'm not going to call a function inside every frame of that movie to find out when it changes.
how do I detect a variable change and then make it call a function?

how do you detect change in a _global variable?
This following is the code I am using which watches for change. (only the local variable)
ActionScript Code:
// Declaring the variable
myVar = "AtoF";
// Callback that will be triggered every time there is a change
[Code]....
I use _global to declare the global variable and its not working with this code.

I was recently asked to create a podcast system which grabs a URL from a certain text file and plays it within the document. It's fairly simple, and I have finished programming it.However, a lot of its users have been viewing the content through mobile devices. They saved it to their device and it crashes if there is no network connection.My question is how to detect a network connection error through URLRequest, and then respond with a function.

Quite simply what should the code look like to include four URLRequest buttons in the same Actions keyframe. I'm working on a slideshow so the actions layer spans four frames. I've tried using four separate keyframes but no luck.

So, i've got an request that returns variables count i0 i1 i2 etc.
I'd like to put them in an array.
var imagecount = evt.target.data.count;
for(var i = 0; i < imagecount; i++) {
image[i] = evt.target.data.["i"+i];
[Code]....
I'd just like to use the i loop number as the variable name. What is the syntax in doing so?

how to pass a variable from FLASH to PHP?I'm trying to upload an image through the URLRequest and pass a unique name for each file.( I want to store the name elsewhere and need flash to know the name of the file.)
Since I'm using the request.data for the ByteArray of the image, I read that I can't use the URLVariables to pass any other variables.
It is almost working, except for the filename.AS3 function calling the request and query string:
Code:
function uploadTheImage(GuidName:String):void
{
//create image
var stage_snapshot:BitmapData = new BitmapData(imgprev.width, imgprev.height);
stage_snapshot.draw(imgprev);

[Code]...
lately i've associated a class file (.as) to my movie and immediately after, when publishing the movie i got the following error message: 1046: Type was not found or was not a compile-time constant: URLRequest. as well as a couple of other related error messages: 1180: Call to a possibly undefined method URLRequest. 1180: Call to a possibly undefined method navigateToURL. when i remove the link to the class file, the problem goes away. also, i have checked the class file for mentioning of "URLRequest" and nothing is there.

Well basically what I want to do is have my code figure out that a variable has changed value and then call a function to store that value in my class.I have a component with a text box in it that displays a value gotten from either typing in the box or moving a slider. I then need the last value (where they stop sliding or typing) to be stored in my class

I have been banging my head against a brick wall regarding the following problem which must be very simple to fix, just can't see the answer.I have a class assigned to a movieclip called canvas. The class is called drawClass. I have called the instance of canvas on the stage 'drawingCanvas'.When I trace "drawingCanvas" I get object drawClass] which is fine. Tracing drawingCanvas.name gets me the instance name 'drawingCanvas'.This is a String variable.Basically what I am trying to do is pass the MovieClip name to another class. In my example the class 'toolBar', which can then interact with the MovieClip.
The problem is passing 'drawingCanvas.name' results in a String, so I get an error saying :TypeError: Error #1034: Type Coercion failed: cannot convert "canvasArea" to flash.display.MovieClip.I can't for love or money find a way to convert a String variable to a MovieClip variable! I have the name of the MovieClip, I just need to tell the toolbar class. But I can't find a way of doing this as the instance on stage is an object of drawingClass, not a MovieClip (unless MovieClips with attached classes are not treated as standard MovieClips?).

I'm building a simple 360 degree image rotation effect using single frames and forward and back buttons. I'm new to AS3 and have managed to create functioning buttons... (so my code may be a bit odd!)But now I also want to advance frames by clicking and dragging on the image itself (or on an invisible button sat on top of the image).Although there are some threads here which have asked the same thing, I don't understand how they were answered. My code is below, and the file I am practising with is on:URL...At the moment if you click on the image area it will advance but as there is no code detecting mouse direction, it just goes forward. Can anyone help me understand how to implement a simple direction detection and then use this to decided whether to advance or go backwards.[code]

I have XML that looks like this:
<question>
<type_elt>
<opt_out_flag />
</type_elt>
</question>
type_elt is not an element name; it might be <single>, <multiple> or something else, determined at runtime. How, given this, can I detect the presence of the opt_out_flag element?
I tried this (where xml refers to the question element):
if (xml.*.opt_out_flag) {
do_something();
}
but even in cases without opt_out_flag the above expression returns true. Obviously I'm missing something, but what is it?

At run time, Is it possible to detect the 'Connection Speed of the user' and change the way my preloader works? Say If the user is on a Dial up connection then play the initial 50% of the movie that has been loaded while loading the remaining 50% in background, If the user is on DSL or cable then load the entire 100% movie and so on.
