How do I execute callback functions dynamically by passing a function in as an argument to another function?
Look at this example:
Code:
package {
public class myClass extends MovieClip {
public function myClass(callback) {

My web application pass a javascript object to flex application using addCallback function.
when the flex application is in modal dialog in safari browser, the object in the flex application is null and when I open the flex application just in a new window, the object is passed correctly. But, I need the showmodaldialog to show the flex application.
The flex code:
ExternalInterface.addCallback( "handleEvent", handleEvent );
override public function handleEvent( event:Object ):Object {
Alert.show(String(event)); .....
I have a global function that does some stuff with a LoadVars in it.I 90% of the cases, the onLoad reference of the LoadVars is the same, but I sometimes need to do something else when the LoadVars is loaded.Is there a way to pass a function reference to a function so that I could do something like that :
[AS]
_global.function myFunction(maybeFunction)
{
myLoadVars = new LoadVars();

Well I want to set up a function that will calculate the x position of where my MovieClip's instance name will go. Here is the code i currently have.
function xBtnPosition(btnName: String, btnXpercentage: Number):String
{
var xFinalPosition: String = -(((btnName.width * btnXpercentage) / btnName.scaleY));

I saw a post that touched on this, but I thought it deserved a thread of its own for explicit verification. It seemed that some of the resident geniuses here had given the thumbs-up to passing your whole doc or app class to a function. Please correct me if I'm wrong, as this sounds convenient but I assumed it would cause heart attacks and CPU meltdowns.
EXAMPLE: Say I have an app class that controls my entire game (or slideshow), and it has an ENTER_FRAME scrolling function that's 50 lines long with tons of conditionals so I want to take it out and make it an external file. I pop it into a new .as file but now all my variables are out of scope. I could pass them each individually, but there are so many it's impractical. So my question is: good or bad practice to pass the entire class?

For a game I'm attempting to develop, I am writing a resource pool class in order to recycle objects without calling the "new" operator. I would like to be able to specify the size of the pool, and I would like it to be strongly typed.
Because of these considerations, I think that a Vector would be my best choice. However, as Vector is a final class, I can't extend it. So, I figured I'd use composition instead of inheritance, in this case.
The problem I'm seeing is this - I want to instantiate the class with two arguments: size and class type, and I'm not sure how to pass a type as an argument.
Here's what I tried:
public final class ObjPool
{
private var objects:Vector.<*>;
public function ObjPool(poolsize:uint, type:Class)

View 2 RepliesI'm trying to define this function so I can pass the CardButtons sprite to the Add Cards function. It "works" but there's one problem: the CardButtons sprite used in the function is determined by the value of i at the time of the function call (or in other words, the value of i when I click the sprite).
I want the sprite passed to be literally the value of CardButtons[i] at the point when the function was defined.
CardButtons[i].addEventListener(MouseEvent.CLICK, CardFunctions[i]= function(){ AddCards(CardButtons[i],PlayerHand[player-1][PlayerHand[player-1].len gth-1]);});
Is there a way I can do this, or is there a better way to do what I'm trying to do?
I guess for further example:
I want CardFunction[0] to store the AddCards function with the value of CardButtons[0] passed, it should NOT be dependent on the value of i.
I need to pass a variable to a function inside a function. However this parameter (i) seems not to be passed (to function ...onRollOver). This is required to attach a textfield to a movieclip (reading the adress and showing it as a tooltip).

var attachElecCity = mc_map.mc_places.attachMovie("Plant",

How do I keep the cycles active, and also call a function at the end of each cycle/tween? Right now I can remove the soundHammer call back and the tween will continue to cycle, and if I remove the cycle soundHammer is called properly, but obviously it doesn't cycle anymore.
Lets say I add a callback function to be run every frame the AS2 way.
Code:
this.onEnterFrame = myFunction;
If I add another enter frame listener, will this replace the old one, or add to the old one, so both functions will run when frames are entered? And how do I remove these listeners?
I'm working with arrays in AS3 and some of the utility functions described in the livedocs such as filter() or some() would be very useful to me, if only I could pass parameters to them...
Actually, I cannot find a single example of the use of these functions with custom parameters passed to their callbacks. Everywhere, it is always used with constants ! E.g. on this page: [URL]
var arr:Array = new Array();var totalElements:uint = 100;for(var i:uint = 0; i<totalElements; i++) { arr[i] = Math.round(Math.random()*100);}function isLargerThan90(element:*, index:int, arr:Array):Boolean { return element > 90;}var highestNumbers:Array = arr.filter(isLargerThan90);trace(highestNumbers);
What I need is a kind of "isLargerThan" function with "90" as an argument's value, not as a constant. Something like
function isLargerThan(element:*, index:int, arr:Array, param:Object):Boolean { return element > (param as Number);}I find it very odd that I cannot find no mention of the way to do this on the whole WWW, because that makes these utility functions absolutely helpless in many many cases and programming with arrays a real pain...
When you call a method of a class inside a callback function, you can not use this object.To call the method, in javascript, I declare that variable, assign this to that, and use that inside the callback to call the method of this.In actionscript, do I have to do the same way as I do in javascript?The following code is the example to use that to call a method inside callback.Are there more simple way in actionscript?

import caurina.transitions.Tweener;
class Scanner extends MovieClip
{
public var Scanner00_mc:MovieClip;
public var Scanner01_mc:MovieClip;

Makes sense as for the sequence, what doesn't make sense is why Tweener fail to loop back to the "fade" function ? They are suppose to be calling each other in an astable/blinking manner.
I suspect it's a scope problem but I don't know how to fix this, it seems AS2 Class doesn't know that there is a fade function within itself after the second Tweener call.
I rarely use NetStream or any video in my projects, but someone I email with was wondering this, and I have no earthly idea.
Is there any reason why the NetStream's "onMetaData" event cannot be listened to using addEventListener, but instead requires you to use a callback function?
Is it faster, avoiding the overhead of events? Is it to prevent more than one listener being attached?
There is some way to make a tweet from an AS3 app, passing a message and a url to tweet, and executing a callback if the tweet was succesfully posted?

I'm currently working with soundmanager2 in an IE/flash context (not html5). The issue is that audio playback of mp3 content does not occur for the following case where the 'onload' callback function is defined as null OR as a function that does almost nothing.
[Code]...
I don't think this is possible, but is there a way to validate the arguments a callback accepts. For example someone passes me callback "mycallback", I want to assert it accepts an argument String.
public function addHandler(handler : Function) : void{
//pseudo code
Assert.functionAcceptsArguments(handler, String);
}
whenever I try to call the removeMovieClip function in a callback handler, it just doesn't work! Maybe I'm tired, or I've just missed something this is apparantly obvious. In my code exert below, is just a simple script that attaches a movie clip to stage (square_mc) and creates a duplicate instance. When the component button is clicked, I want the original movie clip to be deleted, but nothing happens!
Code:
this.attachMovie("square", "square_mc", this.getNextHighestDepth());
square_mc.duplicateMovieClip("square_mc2", this.getNextHighestDepth(),
{_x:50}) var listener:Object = new Object;[code].............
it seems to me that when you use laco tweens and callback a function, you can't pass data in that function, because the function won't wait until the tween is finished but is being carried out right away. For instance, I want to tween movieclip MC:

Would I be able to get that function executed in the Flash application?
make function execute only once per second in ActionScript 2.0? As always I'll start from example to explain my problem...I have aprox. 15 buttons on my stageand all of them are calling the same function, but with different arguments. This function executes some effects, that lasts for 1 second. If someone will click on that buttons more often, than once per second, that will look horribleI can disable that button, what was pressed, but this will not solve the problem, be cause someone in a hurry can click another button
