In as3, I am adding event listener and then attaching the anonymous function to it:[code]Now this whole piece of code is looped n times. Now, I have n myBoxes and whenever I roll my mouse over the box, it should alert the name. But, what I see is that the last value of count is used by each box. How can I pass parameter or value to the anonymous function? ( as roll over , I believe, expects only one variable)

I'm having some trouble passing parameters with a function that is itself being passed as a parameter.In my application code I'm instancing that class five times:they are buttons in a menu.In that class, I've got an onRelease handler that does a number of things when a button is released, one of which is to invoke a function that is defined in the application level of the code.My problem is that I don't know how to send the function parameters.In my StandardButton class I have:
class StandardButton extends MovieClip
{
/* define properties */[code]..........
The function is successfully being "sent" to the StandardButton class, but without any parameters.How can I send parameters to the class instance with the way I've got this architected.
I'm just looking for clarification on the passing of a parameter and why/how it works.
In this example, it looks like you create a parameter to be passed in called 'evt', but I don't see it used anywhere in the function. [code]...
Forgive me for this stupid noob question but I want to call a function (loadList) that originally gets triggered after a mouseevent from another function (addToXML) that does not have an event.
The loadList function takes info from a XML var, sticks it into an array which then gets loaded into a tile list and that is working fine.
The addToXML function when called adds elements to the XML var after which I want to call the first function with the event parameter so it refreshes the items in the tile list.
I know it can do this by creating a new array and loading that into the tile list in the addToXML function, but it be much simpler to just recall the function.
I have tried things like
Code:
addToXML.addEventListener(Event.COMPLETE, loadList);
but all the event constants I have tried give me error messges like "1061: Call to a possibly undefined method addEventListener through a reference with static type Function."
Getter functions allow obj.meth syntax instead of obj.meth(), I'd like to create an anonymous one of these to return from another function. function get ():Object { } is invalid syntax. I don't suppose Flex offers an easy way to get this functionality, if it's even possible?
View 2 Replieshow to pass parameter to eventListener function.[code]
View 1 RepliesIŽd like to know how could use the Timer class extended.IŽm trying to pass a parameter to the constructor function, so I can use it inside the listener.
HereŽs example:
[CODE]
package { import flash.utils.Timer import flash.display.DisplayObject public class ChangeColorTimer extends Timer { public static const CHANGE_COLOR:String = "changeColor"; public var obj:DisplayObject public function ChangeColorTimer(delay:Number, repeatCount:int, obj:DisplayObject ) { super(delay, repeatCount) this.obj = obj } } }
[/CODE]
That was the ChangeColorTimer that extends Timer.Now, IŽd want to know how would I use ChangeColorTimer.I thought it was the same as using Timer.IŽve tried this:
[CODE]
public function changeColor(mc:MovieClip):void { var colorTransform:ColorTransform = new ColorTransform() colorTransform.color = 0xEE0000 mc.transform.colorTransform = colorTransform var changeColorTimer:ChangeColorTimer = new ChangeColorTimer(400, 1, mc) changeColorTimer.addEventListener(ChangeColorTimer.CHANGE_COLOR, setNormalColorListener) changeColorTimer.start() } private function setNormalColorListener(e:Event):void{ trace("called") }
[/CODE]
I called changeColor, but, I donŽt get "called" in the output from the setNormalColorListener listener.
i want to pass by reference so i can use this variable outside the function.
What im doing is creating a global variable such as var cont:int; and then in a eventListener like enter_frame (stage.addEventListener..) calling a function called "mover", this function modifies "cont" value and i just want to print this value modified. The issue is i cant pass the value by reference just by const :S. The function is void, but if i change it to return int, its useless because each time i call the function, the value i want to return its created each time with a new value, beacuse i need to declare it so.. I read i can use a var such as Object but i really dont get it (im used to c++ i have to say)
Is there any way to pass parameters to mc.onRelease?

I need to do this from elsewhere on the embedding HTML page using JavaScript.

Does this require a listener in Flash that listens for the call, excepts "foo" and then calls the flashFunction and passes "foo" to it?
Can this be called directly without a listener?

I have a custom component written in action script (no UI). I am instantiating this component in an mxml file which is present in a library project. The custom component has a constructor which takes one argument. The library project is used in some other web project from where i pass a variable to this mxml file.[I have linked source of the web project to source of library.].
I have a static variable in my library project which holds the reference of the current object of the project. I need this static variable in order to use properties present in the mxml file. I am unable to use the property sent from the web project in the constructor of the custom component, but able to use the same in some other function present in the custom component.
I'm using an HTTP request to download a image in binary format. When the downloading is complete, I want to process it, but I also want to pass the image's ID to the complete handler function.
[Code]...
For example:
for(var i:int=0; i<someArray.length; i++)
{
var loader:Loader=new Loader();
loader.load(new URLRequest("http://testurl.com/test.jpg"));
[Code]....
The second paramter (i) for imageLoaded is always 1, I guess because i no longer exists and is defaulting to 1. Is it possible to get that second paramter to be evaluated when the load is started rather than on complete?
I have this class ('Scheduler.as'):
[Code]..
So as you see in your test-run the first two calls work fine, the one that calls a function that takes no parameters and the one that takes one parameter. The problem is when I need to pass more than one parameter! Solving the issue: Well, I know it'd be solved if I could simply retain the ...args as is, and pass it on to the this.m_function.call call. Another way, maybe is to have some sort of a foreach loop which would feed the designated ...args when the time comes, yet again, how would I refer/pass it?

I have an event listener with an anonymous function literal, rather than a function reference. What I am trying to figure out is how to remove that event listener.Obviously, I need a reference to the anonymous function, so the two functions are ===. But, something is going wrong... it just doesn't work, ad this situation doesn't generate any feedback to tell me what might be wrong.There is some good info here, but not a clear explanation.

I need to be able to use param value out of the function, because a I need to perform a switch with this value, since the function wich receives de param value is an anonymous function I dont know how to do to get the value from outside the function because a dont have a reference name to the function so, the normal way to return a value is not going to do the job.
I am trying to play an MP3 File in Flash Lite 2.1 (I'm using Flash 8 to develop it). The filename of the MP3 file is imported from an XML file.Here is a copy and paste from the help file on how to do this:
// create a new Sound object
var my_sound:Sound = new Sound();
// If the sound loads, play it; if not, trace failure loading.
my_sound.onLoad = function(success:Boolean) {
[code]....
When I test this code on its own, it does work fine for me. However, I want the above to be executed inside a function that does a number of other things...
Here is a sample of what I'm trying to get working.
function myMusic() {
// create a new Sound object
var my_sound:Sound = new Sound();
// If the sound loads, play it; if not, trace failure loading.
[code]....
I think it's got to do with the fact that once I put it inside a function you are nesting functions (there is a function call from the onLoad event).
I tried changed the line:
my_sound.onLoad=function(success: Boolean) {
to
my_sound.onLoad=myFunctionName(parameters go here)
and then I created a funciton called myFunctionName but I wasn't sure how to send the sound object or what parameters the function should have or how to get the .start() method to work inside the new function.
up.addEventListener(MouseEvent.CLICK,
function clickFunc(event:MouseEvent):void
{
revealSpinner(event,51.42,1,spinner);
[Code].....
The above code adds a listener to a couple of MC's. Originally the methods were anonymous but I have named them clickFunc() in order to try an reference them in my remove listener.
Here is my remove listener code. Both of these snippets are in separate functions. The add listener method is called before the remove method.
up.removeEventListener(MouseEvent.CLICK, clickFunc );
down.removeEventListener(MouseEvent.CLICK, clickFunc);
As soon as I publish the movie I get this error:
1120: Access of undefined property clickFunc.

View 1 RepliesI'm trying to differentiate anonymous functions like:
function() { trace("WOO"); }
from the other ones ('named'?) like
var _FUNC:Dynamic = function() { trace("WOO"); }
The reason I want to do that is because I can't compare between two anonymous functions, because they are two different ones.
var _TEST:Dynamic = function(a:Dynamic):String {
var _TESTA:Dynamic = function() { trace("WOO"); };
var _TESTB:Dynamic = _FUNC;
return (a == _TESTA) + ", " + (a == _TESTB);
}
If I run _TEST(_FUNC);, I'll get back "false, true". Even though they are the same function, they are NOT the same object.Is there a way to compare those such that functions that they are the same if they perform the same task? Is there a way to serialize functions? So that maybe I can compare the serialized representations and see if they share the same 'code'.
In c++ if I have a function that takes a class I have defined elsewhere as a parameter like so:void moveto(CPoint2D point) { ... }I can invoke it and pass along data to it like this:moveto(CPoint2D(0,0));basically creating the object and invoking it's constructor to be passed to the functionIs there an equivalent to this in AS3?if I have a function like this:function initialize(min:Point, max:Point): void { ... }how do I do something along the lines of :initialize(Point(0,0), Point(10,10))This throws an error im assuming because it thinks I want to cast something to a point and the notation I found earlier to do something similar only seemed to work if using the basic Object class.

I'm new to AS3, and can't figure out why this loop isn't behaving the way it "should."
[Code]...
How can I give each anonymous function a reference to each object represented by f, rather than a simple reference to f each time? Specifically, why is it that each copy of the anonymous function gets bound to a single reference to f? How (I should say why) exactly does AS3 differ from JavaScript in this regard?
