ActionScript 3.0 :: Return Variable From Eventlistener Called Function
May 2, 2009
I have a function inside of a class which is called by an event Listener I need access to a variable inside the function after the eventListener has been called. The variable name i need is stream and the function it lives in is called NetStreamxx. I tried to return stream but i don't know how to access the returned value here is the code
create and send a variable called "return." But that conflicts with a word used in actionscript.[code]is there anyway to work around this naming conflict?
I'm using an AMF service that was built by someone else. Basically what happens is that some info is passed to the AMF service and it returns true or false.I want to be able to pass in various info to the a function that calls the AMF service(submitTracking) and then get the true or false value returned in onResultSubmit to be passed back to submitTracking.
var screen:String; var buttonnumber:String; function submitTracking(screen:String, buttonnumber:String) {
I have a set of Cue Points in an FLV I'm playing. It's an interactive quiz, so the idea is that flash will change a variable, theAnswer, to a different letter depending on which question it is. The answer to question 1 is B, question 2 is D, etc. Either the cue point event listener isn't working, or else it is working and Flash isn't declaring the variables. 1120: Access of undefined property theAnswer. I literally can't find a single problem with my code. I have an almost identical Event Listener further down which works.
I have a number of nodes that are plotted on stage. I want to display the value of each node when hovering over the node (using the Tooltip class). [code]...
why my variable does not get updated when I try to modify it from an event listener function? for example in the code below _resultXmlList will be null if I try to get it from getXml I think there is no access to member variables from an event listener.
So I've got a function that does several things: It creates video cue points, loads content & executes a function based on those cue points, and finally, sets the eventlistener for the video.
The problem I'm having (after tracing it out) is that the variables within the function seem to be stored as an 'array-like' deal. In other words, the variables output as they should when initially clicked. Next time the code executes, it outputs the newest variable values then IMMEDIATELY the first variable values. This output 'builds' and builds but ultimately the content never dynamically changes as it always ends up loading the first content that was loaded very first time out. I'm *guessing* it has something to do with the event listener being re-instantiated? Tried modifying where I add the listener to no avail.
Any thoughts?
Code: function vidPlay(vidName) { swfText.gotoAndStop(1); // mc1 to load external data & play a function swfText._alpha = 100;
[Code]....
I still haven't been able to figure this one out. My best guess is something to do with the eventlistener being re-instatiated each time the function is called, but I'm not sure. Again, it seems to either be 'storing' the variables in a backwards array somehow (first variable is stored and accessed last at all times) or maybe somehow it's creating multiple instances of the eventlistener and the variables are being pulled from the first iteration of it.
I am trying to add a Paypal Buy-It-Now button to my Flash site.The basics are simple enough:
this.cmd = "_s-xclick";this.hosted_button_id = "1234567"; this.getURL( "https://www.paypal.com/cgi-bin/webscr", "_blank", "POST" ); ...however, one of the button parameters to post is called 'return'.
I have an MC object called with linkage to be treated as a class in the library,part of the code is what follows (what is relevant to this problem):[code]If I drag and drop the object from the library onto the stage to instantiate it and call the function from within the object, then there is no problem, and the code is executed with no problem. In the main movie clip, I want to create an instance of this class with code, add it to stage and call this function with the following code:[code]
Through the use of flags I have confirmed that we in fact enter the function setTable, and that this error is produced once I try to reference the cardArray.I do not declare the array outside that function because I need other functions in that MC to be able to see it. Relocating the declaration does not solve the problem, because then the interpreter advances to the lines where I reference other functions declared in the MC (which I want in there), and the same problem arise: it has not yet seen the declaration of functions like the custom shuffle function for arrays
I am trying to make a simple mp3 player using flash. The songs are loaded using an XML file which contains the song list. The following code is inserted into a new keyframe.
The problem over here is in the nextSong() function. I am unable to preserve the value of currentIndex. Although I am incrementing currentIndex every time the function is called, but the value remains unchanged.
I'm not sure exactly what's going on here (maybe I'm not understanding how the timeline executes?).
I have a game that has the menu in the first frame, the game in later frames. When the game is won, the user is able to click to return to the menu. Using trace(), I've found that the click reads, and it starts to execute the actions that have been written in the 1st frame. But, when it gets to the line that adds an event listener to a button on the stage using solo.addEventListener(MouseEvent.CLICK,goSolo) (solo is the name of the button on the screen), it returns:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
The line executes just fine when the whole thing initializes, so I don't know why it's not working when it restarts. Is the code getting read before the stage is populating when I return the user to the main menu using gotoAndPlay(1) from the click listener? It doesn't make a difference if I use gotoAndStop(1). What's a good workaround?
Or is it because the button is in a layer lower than the actions? (I've always put my actions in the highest layer, and don't remember ever having this problem before). But why then would it still work at the very beginning but not with the restart?
I'm trying to create a custom function called "turnOn" with (name) as the function variable(?is that how I should refer to it?). This function is an if/else statement that will be called through an on(release) button event.
The if has a bunch of && conditions, if true gotoAndStop on frame two of specified movie clip. But I'm trying to write it put it in a function so that I don't have to put all this code on every single button. So i'm using the "name" function variable to specify the movieclip that should be affected by button action, but it won't work.[code]...
Use Flash CS5 (and AIR, though this does not seem like it would be AIR related) in Win XP 64 I have a MovieClip symbol in my library with the identifier 'Puzzle10Piece10' with the following actionscript attached to frame 1 of the only layer with the following actionscript:

This runs contrary to my understanding of the pre-compiler and code execution order. In my way of thinking, any reference creation and related memory allocation is made when the object is instantiated, and indeed that allocation, unlike C depends not on code order (declaration before use), though this is an order that would satisfy even the C pre-compiler. If I understand the Flash compiler at all, it's not even a question of 'code order'... the symbol is pre-compiled such that for it to exist... for it to be instantiated, the variable would exist before the function would even be 'available' to be called internally or externally. Is my thinking way off, or is this a bug?
I have an AS3 program that calls a function multiple times. The function must return multiple variables, so I created a class for the function to declare an object containing all of these variables. For example, here's my class:
package { public class PER { [Code].....
Let's say the calling program calls the function, which returns the variables into data_set1 (where data_set1 depends on input variables arg1, arg2, arg3) using:
var data_set1:PER = function_name(arg1, arg2, arg3);
The calling program does some stuff, then calls the function again, but returns the variables into a new variable name, data_set2:
var data_set2:PER = function_name(arg4, arg5, arg6);
My intention is that data_set1 and data_set2 are different (e.g. not linked together).
My question is, given that arrays are passed by reference, will data_set1 be modified to agree with data_set2 upon the 2nd function call? Why or why not?
I have been making an image gallery and I want to add an image text to bottom margin of every image which heights differ from one another. I am loading images in Loader.as. That's why I have to use the following script to get the height of the first image from the Loader.as:Main.as:
public var textbox:Textbox= new Textbox(); public var imageText_tf:TextField = new TextField(); imageContainer.addEventListener("imageLoaded", function(e:Event):void{
I have a "var counter:Number;" that changes when a function runs I need to know when that variable changes and what it has changed to so another function can use it
I'm trying to setup something like Aspect Oriented Programming in Actionscript 3, basically the only thing I need to be able to do is something like this:
Is is possible to attach an EventListener to a function? Such that if at any point in a function's execution an Event is Dispatched the EventHandler will get fired?
i've been at this for days, how do I get xmlData to load information outside of the function LoadXML? I'm willing to donate to the person who can get me something that works or this to work. I desperately need this.
I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):
I have three functions and I want to play them one by one when each of them completes the tasks inside. How can I add an eventlistener to a function to check if it is finished?So the following is the example:
function generateIdeaBalloons():void { var ideas1:MovieClip = new idea1 (); ideas1.x = 480; ideas1.y = 248; container.addChild(ideas1); TweenLite.to(container.ideas1, 1, {delay:0.5, x:50, ease:Quart.easeOut});}
I want to use tweenlite to tween a navui_mc onto stage when I rollover another mc. Once navui_mc has completed the tween, I want to ad an MOUSE_OUT eventlistener to navui_mc, so that when I mouse off this mc is tweens out.The function call at the end of the tween seems to work as it is tracing that it has completed, but i dont think I can have the eventlistener in a function?
I have a main menu of buttons which alpha is set to 0 when you go to another page. I've made the button-menu fade in again when you return to the page. When you click on a button I want the buttons to disappear again, and I dont want the fade in to continue. This is my code:
function fadeIn(mc):void { var nNum:Number = 0; var myTimer:Timer = new Timer(50,21);
Code: function enableButtons():void { for (var i:uint=0; i<40; i++)
[Code]...
I have 40 buttons on the stage. Their names are contained in the Array musicGrid. What I'm trying to do with this code is attach an EventListener to each button so that it will call the function mgMouseBehavior with a parameter to identify the button. For example, I want the button at musicGrid[0] to call the function mgMouseBehavior(0). I want the button at musicGrid[32] to call the function mgMouseBehavior(32), and so on.
However, if you try to add parameters to mgMouseBehavior in the addEventListener, for example:
I'm trying to execute a fucntion by calling it through an event listener I can't call it directly seems to be out of scope or un intialized or something. I've had luck calling variables in this manner but have never tried to call a function. Can I do it through the event?
I am trying to make a subclass of flash.display.Loader, which should do something when the loader completes loading the content. So I do addEventListener(Event.COMPLETE, onComplete) on my loader subclass. But this Eventlistener is never called. Is this supposed to happen? Can't I use an Eventlistener on the class that dispatches the event? My code looks like this: public class MyLoader
