ActionScript 2.0 :: CS3 Detect Variable Change
Nov 7, 2010
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?

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).

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.

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?).

So I'm trying to detect if a variable has been changed by a swf loaded into another swf.What I'm doing is when a thumbnail is clicked on the child swf I want it to fire a function on the main swf. I can get the model to trace out when the value was changed inside of the child swf by itself but when i load it into the main swf I can't get the onModelChanged event to fire off.Container swf as
ActionScript Code:
package {
import flash.display.MovieClip;

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.

I'm creating a board game which has 3 variables, p1Move, p2Move and activePlayer.
p1Move and p2Move store the p1 and p2 location on a game board. activePlayer stored who's turn it is at the moment.
I am loading a value in from a text file which changes the value of move. This all works fine when i designate a player directly:
ActionScript Code:
p1Move = [insert variable name],
but i want to designate dynamically based on who's turn it is.
Something like this:
ActionScript Code:
_root["p"+activePlayer+"Move"] = Number(this.varAmount);
so that flash changes the value of p1Move (or p2Move depending on who's turn it is) to varAmount. varAmount is the variable being read from the textfile.
Hopefully that all makes sense. Basically i want flash to change the variable associated with the active player only.

I have one swf file that containes a mc using an easing function to move an arrow around. That mc has the instance named myruler. The arrow moves based on the value of a variable named "y". This swf also has a mc that I use as a container to load movies into. The movies that are loaded into the container mc have buttons that I would like to use to change the value of the variable "y" in the movie clip named myruler found in my base swf. Did that make sense? [code]...

Can I detect a change to a variable (a data string)?
I am making a AS2 SWF (player level 7) with a combobox page navigation. I have a page name variable that I am changing from outside of the SWF with Director and Authorware using (I believe) FlashVars. The variable (internally) is set by default during SWF initialization. The external variables values allowed are always one of the combobox's data field values. The combobox default variable is not always index positon 0 (zero). Or the order of the data either. The variable can get changed internally by the nav combobox used for navigation independent of the external variable. - this works When the shared nav var is changed from the external source, the combobox needs to change to the match the corresponding combobox's data variable. This is what I am trying to do. I can change the combobox setting programatically (index) but not get it to recognize it as a change event. Or tell it programatically
Can the combobox be selected by the data variable or is the only option to use the index (and loop through index values to match variable to data field)?
And update the combobox selection (and as a result the nav page) by triggering a change event programatically?
Detecting the var change cleanly without the OnEnterFrame trick is my goal - if it even works in the version I have to use (flash palyer 7).
