Flash :: AS2: Call Method When New Property Is Set
Feb 7, 2012I have a dynamic Class and what I would like to do is call a method everytime a property is appended to the class during run-time.

If I have a .mxml file that has a method in it and a public property, can I have the method execute whenever the property changes.
<?xml version="1.0" encoding="utf-8"?>
<mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
[Code].....
In another .mxml file I have added this .mxml file like so:
<viewComponents:MyViewComponent myProperty="{myVariable}" />
To my knowledge, there are 3 options:1 - parent.publicPropertyOrMethod.2 - using static vars/methods.3 - dispatching events.Under best practise for OOP development, which is the "best" method? Are there any more?I dislike #1 and never use it as it and can easily descend into hideous parent.parent.parent references that are easily broken. #2 has it's own problems whereby attempting to get/set instance variables doesn't always work through a static function (I am yet to completely understand this). #3 is great for triggering methods (I use this the most) but sucks for altering class properties and suchlike.

I need to get a javascript var in my Flash application. I like to be able to just set a variable in the javascript (client constraints) rather than define a function.
Can this be done? I am trying to use the ExternalInterface.call()
AS:
ExternalInterface.call("function(){return window.someVar}", null);
JS:
var someVar = "Test";
This does not work and I suspect it is because the ExternalInterface.call() does not like the anonymous function.
I am getting this error: 1180: Call to a possibly undefined method startWorld.but the method startWorld is defined as you can see in attachment.
View 4 Replieswhy this is not working.I have an application with a new class I just created. The class loads, but will not call it's own internal function.
package com.parkerandkent.components.classic.photogallery {
import caurina.transitions.Tweener;
import flash.display.MovieClip;[code]....
"Test 2" will not fire here.And I get this error message:
CallTag.as , Line 10 1180: Call to a possibly undefined method init.
I have a class. I can call the constructor (initialize the class), and the constructor can then call a function/method inside it's own class (so I know it works), but when I try to call the same function/method myself from the instance of the class I just initialized, I get an error.

How to make it workable? Anyone faced with such error?
I'm looking for a way to call a method for ALL children elements of a DataGroup from the DataGroup. The problem is that when using the creationComplete event to call a method of a child that method is only called once for every itemrenderer (child) object. after the item was drawn once. now i want the children component to call a function everytime the datagroup containing it changes its data. Using "updateComplete" or "dataChange" inside the children (itemrenderer) component would work, BUT "updateComplete" and "dataChange" is called everytime i change the view (e.g. scroll my list) - thats not what i want.

View 2 RepliesFor example, if an application uses class, method, or property which is supported only by Flash Player10.When you run the application on Flash Player9, what will happen? Flash Player will be crashed? Or Flash Player will show you a message screen to upgrade your Flash Player? Or the application will normally run and will ignore the part which uses the unsupported class, method, or property? Or the application will cause a runtime error when the unsupported class, method, or property are called?
View 2 RepliesI have an issue with my eventListeners with the URLLoader, but this issue happens in IE, not in FF.
public function getUploadURL():void {
var request:URLRequest = new URLRequest();
request.url = getPath();[code]....
The issue is that my getBaseURL gets executed automatically after I have executed the code at least once, but that is the case only in IE. What happens is I call my getUploadURL, I make sure the server sends an event that will result in an Event.COMPLETE, so the getBaseURL gets executed, and the listener is removed. If I call the getUploadURL method and put the wrong path, I do not get an Event.COMPLETE but some other event, and getBaseURL should not be executed.
That is the correct behavior in FireFox. In IE, it looks like the load() method does not actually call the server, it jumps directly to the getBaseURL() for the Event.COMPLETE. I checked the willTrigger() and hasEventListener() on _loader before assigning the new URLLoader, and it turns out the event has been well removed.
I simplified my code. To sum up quickly: in FireFox it works well, but in IE, the first call will work but the second call won't really call the .load() method; it seems it uses the previously stored result from the first call.

I'm still learning AS3.0 OOP, I think that this can't be done with this method. I think I have to make a new Class that extends 'Bitmap', add the prop there, and then in the Main.as make a new instance of that class, point to the target Bitmap, and run the method in the extended 'Bitmap' class (?).
This AS3 function works for normal methods and getter methods:

I am supposed to be doing a project for an animation class of mine. Our professor wants the following- He wants us to create an animated movie clip on the main time-line. Then on a separate layer we can have 2 buttons with some code. One button will stop the animation from playing and the other will get it to play. I have created my animation on one layer and buttons on another layer. Then I have a 3rd layer named actions for my action script. I made sure to give instance names to all my objects. My problem is I go to test movie and I get the following errors for each button I press.

I've got on main timeline (on frame 10) buttons, when I click one of them it goes to its currentLabel"". On curerntLabel at frame20 "racerButton" where I've got some tweening. At currentLabel "boardButton" at frame30 I load external swf. The problem I've got is when I press any button everything works fine. But when I first press button "boardButton" at frame30 the ext.swf shows up fine, but when next I click the button "racerButton" at frame20 the tweening doesn't work there and it gives me error

I have a drag drop routine, with the dropTarget consisting of a sprite with a label containing text on it. The problem is that depending on the mouse cursor position on the item being dragged, the drop registers either with the intended target Sprite, or with the textField of the Label on the Sprite.Is there a neat way of finding out what class the drop target is? My attempt gives me the following error.
