Flash - Listener Functions Not Acting As Closures?
Jun 8, 2011
Reference objects on stage/frame from document class. AddFrameScript seems to do what I need it to, except for one thing. In the function I'm passing to be added as a frame script, I want to dynamically create some event listeners for buttons, but variables I want closed over the listener functions aren't behaving as expected -- they all end up having the last assigned value of the variable rather than the value it had when the function was defined, as if different scope rules are in effect than normal:
addFrameScript(node_frame - 1,
function() {
stop();
question_txt.text = node_question;
answers_xml = node_xml.answer;
[Code] .....
But then afterward, if I click any of the three buttons, they all trace:
3A
Do frame scripts observe different (dynamic rather than lexical?) scoping or something?

Code:
trace("Hello!");
I'm up late coding and I've come to a halt here's why:
I'm looking (desperately) for something that will explain why my "public class marquePage" is not working properly. I don't have access to the actual file right now - on a friend's computer - but i'll try and make this clear, here it goes :
Code:
// example : (having declared the namespaces at package level and embedded the pictures in separate classes "photosMP", etc)
public var ceNom:Namespace;
public var cetteListe:Array = [photos, dessins, livres, maous];
[Code].....
Somehow, the event listener doesn't want to know about namespaces... in fact, everything comes up ok except that when you click on any of the bookmarks (cetMP), nothing happens at all

why can't we set vars for functions of a Event Listener. To be more specific, this is my code:
Code:
package
{
import flash.display.MovieClip;

Basically what I want to do is call a function attached to an event listener, without the event actually happening - for example:I have a function that is attached to Event.RESIZE.I would like to call that function from time to time, but this function of course requires an Event argument, so attempting to just call the function throws an error that it expects 1 argument and got none.

I have what I think is a scoping issue with a listener. I have a movie clip which contains several picture management functions. I want to add a listener to it so that the next image loads before it is processed. Where do I put the listener - In the MC or in the root? At the moment, I have it in the MC but it does not run the function. I created a test function in the root which runs the listener no problem.

I am currently having a mc in my library use a class. The mc is duplicated and put on the stage. Inside the class the mc gets a rollover state. Problem is that, although the rollover listener and function 'works', any action that is given is applied to all objects linked to that class.
Code:
Select allpublic class cities extends MovieClip {
private var theStage:*;
public function cities(cityid:int, cityname:String, mymc, ref:*) {
theStage=ref;
this.alpha=.85;
this.buttonMode=true;
[Code] .....
So pretty much on rollover on one of the mc's makes them all alpha = 1 and rollout makes them all alpha = .85 instead of the one being rolled over. It does make sense I guess because they are all calling that same function I think. I also tried referring to the specific mc (mymc) instead of the parent and this.

ave anyone run into a SWF acting differently when loaded in IE8? I just finished a banner/header for a client that is working perfectly except when loaded in IE8, here is what is happening...

Basically my masks are not being loaded on init()... I'm loading external XML so I'm thinking it might have something to do with that.

I have a MC(image) in the center of my screen, and have two buttons, one on right and one on left side of that MC. I want to scroll (image is like a menu) that MC left or right on mouse events, down or over. So, I just want to change MCs X value while holding mouse button on buttons or just hovering over them. I have managed to do that, but it's only moving by one value I have entered after a mouse event. Here's a piece of code I did.
buttonL1_btn.addEventListener(MouseEvent.MOUSE_OVER, buttonL1Pressed);
function buttonL1Pressed(event:MouseEvent):void{
var temp:int = 0;
var temp1:int = 0;

I have this weird thing happening with flash and a dynamic textfield. Basically, someone rolls over a marker on a map, and a tooltip pops up with a dynamic textfield. The textfield is set to multiline=true and wordwrap = true, and I defined a specific width of 160 pixels.
The problem is, some of my text is jumping to the next line, some of it is just getting cut off. So if I have a line like "The Cat Jumped Over the Box", On one line I will see "The Cat Jumped" and on the next line I would see "the Box". It looks like it is masking out the "over" line and not pushing it to the next line.
It's not doing this for everything, just some longer lines. This is a really weird bug and I have tried for 8 hours to get this fixed. Has anyone ran into this problem before?

why the getDefinitionByName function works with "com.foo.Bar" and gives error with "com.foo.Rab"?My only clue is that the class com.foo.Bar was created before importing the project to Flash Builder 4.5 for PHP (4.5.1 namely).
My question is very specific, in fact you could try for yourself if you had FB4.5.1, a prior version of the same program, and a lot of time. Obviously I'm hoping to find someone who have experienced this particular issue or any related issue with similar functions.

Im adding lot of simple functions to prototypes of top level objects ( Object , Array , String ...) and have 2 questions :
Is possible to add functions to top level's classes in compile-time ?
If not , is there a way to allow this functions to compile ? I dont like to turn off strict mode
ex:
string.removeWhiteSpace();
string.sliceStr("." , "end");
textField.scrollBottom();
this return compile-time error , cause there is no such function , i have to write it in braces :
string["removeWhiteSpace"]();
string["sliceStr"]("." , "end");
textField["scrollBottom"]();
and i like to aviod it )

Here is the problem:
var p:int = 0;
var n:Number = 0;
n = 32.999999999999999;
p = Math.floor(n);
trace(p); // returns 33
n = 32.11111111111111;
p = Math.floor(n);
trace(p); // returns 32
I would expect both of these to return 32. I have searched, and it seems this is an unreported bug in AS3. Or ... am I doing something wrong?

i've been playing around with this dynamic ribbon effect for some days now. It was made in Actionscript 2.0 for Flashplayer 6, now i need to change the Flashplayer to 8, because i made some other scripts which needs the new features in the new player.
But for some reason the animation is acting strange when i change the player. It is like it misses out just a tiny bit of the code, or some function. It is acting like it is stuck in the upper left corner all the time.

i have an odd issue and i know almost nothing about AS3 so im a complete noob please bare with me. I am working with a template .fla for a page flip but i am using a different navigation system for the flipping of the pages. I have worked through all the errors and output problems and i can get the system to work but the moment i try to use other event handlers for the same item it completely blows up the main script to make the page flip that is required. No errors, output problems etc, it just doesn't work. So here is the code.
Code: Select allHome.lnk1.addEventListener(MouseEvent.CLICK, clickHandler, false, 0, true);
function clickHandler(e:MouseEvent):void {
switch(e.currentTarget)

This must be a very basic question, but I'm lost on it.The premise is simple. OnRollOver button 'A' gets color 'X', onRollOut button 'A' gets color 'Y', onRelease button 'A' gets color 'Z'.Now, ofcourse, when a button gets pressed, it gets a highlight color. But as soon as the user rolls out, the onRollOut part kicks in a changes the color back to 'Y', while it should remain at 'Z' as long as no other button is clicked.This is a very basic problem, but I'm still asking. Is there a way to solve this easily? Do I need to start using booleans and if statements to fix this?

I have an image which i am attaching, it is the white portion of the image( i saved it on a black background so it is easy to see, but it is on a transparent background saved as a gif and imported to flash). When my for loop runs, i am trying to position this image on stage programatically, but it seems as it is not doing it right. It scales the image, and positions some all over the place.I wanted the images (8 of them) to appear in 2 colums each one spaced out evenly, but it fails to do that. The movie clip holds the image below. Also since it is a irregular shape, it seems to make the edges look really rought.
1) Why is the for loop generating these images all over the place like that?
2) Would it be more ideal to draw this shape with flash, rather then using a gif image? Is such a shape even possible to draw?This is the code:
import fl.transitions.*;import fl.transitions.easing.*;import flash.events.TimerEvent;
var imageLoader:Loader;
var xmlData:XML;[CODE]............

I'm attaching as many instances of a MC as my xml child nodes length.So basically never know how many of them would be on the stage.Each MC receive actions to perform, nothing fancy and it basically works.But what I want to do is to know when the user has clicked once on any mc so this latter gets 'not enabled' until another MC instance gets clicked. (so my previous MC instance gets enabled, it acts like radio buttons )The point is I know how to do it when the total of instances is defined.I also know the basics of a loop , but I cannot figure how to set up a "toggle" to gets this 'radio button group behaviour

I am trying to change the position of a movie clip which is acting as a menu and loading other swfs onto the stage. The problem is, is that the movie clip is also animated and when an swf is loaded the movie clip appears underneath the loaded swf. What method I should use to change the hierarchy of this movieclip.
