Is there method that gets called just before object destroyed? So I can override it.
Like
protected override function beforeDestuction():void
{
trace("This object is about to be destroyed!");
}
I wonder is anyone can look at this code and tell me why calling the removeSelectedChild works when called from the same document, but returns the following error when called from the child document/component.
"ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller."
<?xml version="1.0" encoding="utf-8"?>
[Code]...
I would like to know the internals of that method, in other words what exactly happens when I call that method. If someone can explian it with a list 1,2,3... would be great. including events..
and the addElement method too, if is possible.
I am having some trouble with my flash application not calling a web service when displaying through a web server.
When I open the html page that embeds the flash file in my browser directly from the hard drive i.e the absolute path to the file. The flash file loads up calls the web service and displays the value returned from the web service.
However, when I open the html page through the web server i.e through localhost the flash file also loads up, but it breaks when calling the web service...it is as if the web method isn't being called.
Is this a problem with flash or maybe the web server configuration? I have changed my flash global security settings and everything to include my testing folder.
I'm trying to add the pop function to a button in flex 4. But I keep getting an error call to undefined method when I try to use it, but it's a built in function isn't it?
<s:Button x="405" y="410" label="Undo last" width="85" click="data.pop()" id="undo"/>
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'm working on a animation for a charity and i need to make some birds fly around the stage randomly, and change _xscale depending which direction they are moving.I have an if() statement to check if the new destination point is smaller or bigger than the current _x position of each bird. This works perfectly, but when i use the continueTo() method, that if() statement isnt being called.here is the code for the birds.
function flight(){
for (var i=0; i<birds; i++){
var bird:MovieClip = attachMovie("crane","crane"+i,i+1);[code]....
Anyway, I have a game with keyboard input and mouse input, and after certain mouse inputs I want to set the focus back to the stage in order to continue listening for keyboard events. I have a simple method in the document class:
Code:
private function setCommandLineFocus( e:MouseEvent=null ):void
{
if( theCommandLine )[code]....
Where "theCommandLine" is a movieclip which gets attached, and is where I send the keyboard events to.
The problem I'm having is this: When the method gets called in internet explorer, it sets the keyboard focus to the URL bar, so you type stuff in, and then hit enter and it reloads the damn page.
I try to do preloder in Flex for my project written in Flash. I make this with the help of this site link text My Flash project have next source in main class called Game
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDown);
stage.addEventListener(KeyboardEvent.KEY_UP, keyUp);
private function keyDown(event:KeyboardEvent) {

Flex application work but Flash application does not react to button presses
how I can make preloader and work buttons together
I've got this issue implementing the Factory method. Following is the snippet of the the main chart class which calls ChartFactory's method to attain the proper object. I Type Cast chartobject so as to be able to call the Show method; I am apprehensive about that as well.
container = new VBox();
container.percentWidth = 100;
container.percentHeight = 100;
super.media.addChild(container);
chartObject = new ChartBase();

What is the best route for an artist to take, when it comes to Flash? Is illustrator the best, since it doesn't use pixels, rather vectors? I had someone draw me something in photoshop, and when I resize it to make it much smaller than its original size, it looks like garbage, and you can see the pixels. Regardless if I resize it in photoshop (gimp) or flash, it looks like garbage if it is reduced in size. I have not dealt with alot of art in flash, so wondering what the best way around this is, besides having the artist draw everything to scale, since the scale is dynamic.

I have a flex application which use DragManager.When I'm loading this application into flash application and trying to use drag'n'drop functions - I get an error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at mx.managers::CursorManagerImpl/showCurrentCursor()
at mx.managers::CursorManagerImpl/setCursor()
at mx.managers.dragClasses::DragProxy/showFeedback()
at mx.managers.dragClasses::DragProxy/mouseMoveHandler()
But, when I simply run a flex application (not loding it into a flash one) everything works properly.
I've noticed that using stage.addChild(obj)(i.e. creating objects on the fly) can slow down frame rates.I was told by several sources that one way to speed up a flash game engine (or any animation where instances are generated as you progress), is to reuse objects in what is known as object pooling.
First of all a bit of background:The game engine I'm working on can be found at: http:[url]....Most objects (i.e. bullets, particles, enemies...) are exported for actionscript, each with a set of actions that are performed each frame, and another set of actions upon being created.Each class has an array called instanceList, which keeps track of all objects currently within play.The main timeline contains an event.ENTER_FRAME function mainActions(event:Event):void, that loops through each of the instances and performs the actions associated wit11h each.It goes through each instance of each class by going through the static array instanceList().
Now what I plan to do is:Have a seperate static array for each class, called inactiveInstances,which keeps track of deleted objects.Introduce a function for adding the objects back to the stage (with the nesscessary variables reset), to give the impression of a new object being created.When objects are destroyed:Should they be removed from the stage and readded latter e.g. removeChild(obj2)/addChild(obj1)? e.g.
Code:
public function instance_destroy()
{
parent.removeChild(this)
//Remove all refferences and listeners[code].....
Ok, so i'm making a game using AS2 (AS3 confuses me even more than AS2) and so far it's going great, but i want it to move to the next level (or maybe a shop between levels) when all the enemies are destroyed... I have Code: Select allenemies = 15; for the amount of enemies on stage. I have Code: Select allif (explode) {this.removeMovieClip(); to get rid of the enemy and i have Code: Select allif(enemies == 0) {gotoAndPlay(3) } to take it to the next frame. I want to know how to update it so when an enemy is removed the original code of enemies = 15 gets updated, meaning when they are all gone it will go to the next frame

i want this clip unloaded (destroyed) when ANY other link is clicked. This clip is an empty container clip that will be generating child clips that will each be loading thumbnails for images. Obviously i need to destroy the parent clip to remove all children without looping, etc.
This movie clip ("TL") is created in a keyframe that is the stopping point of an animation. When a user clicks the Portfolio link from the menu, the menu hides itself, and then goes to a frame label where actionscript awaits. Once there, the AS tells the submenu movie to animate (play). The submenu then plays and stops when it hits a certain frame (the one with the 'stop();' code, lol), and that frame then contains actionscript that generates the Gallery Thumbnails' parent container ("TL"), via:
var TL:MovieClip = createMovieClip("TL",60);
and GT then creates movie clips for thumbnails to be contained in via:
TL.createEmptyMovieClip('Thumb' + i,TL.getDepth() -1);
All this works so far. Now, to get rid of the clip when any other button is clicked, i tell the gallery movie to play again, which alphas it out of sight. So, on the NEXT frame of the timeline AFTER the frame which the TL and children are created is where i need to place the actionscript to unload/remove them. The problem is that there is no method for this! It seems that all the methods for removing / unloading clips only apply to clips that were duplicated or instatiated from loading external files or attaching instances from the library...I need to remove this "TL" clip, and can't figure out how.
Code:
_root.mcMenuGalleryAnimation.attachMovie("thumbsList","TL",60);
TL._x = -300;
TL._y = 0;[code]....
OK, from what I know actionscript in Flex runs asynchronously. I need the ability to run a method in a loop synchronously. Consider this code:

This is not my exact situation as it is a bit more complicated to explain here. There is an abstract class and several custom view objects derived from it. Some of the views are dependent on others being completed first but I cannot seem to order them in the correct order. TIMERS are not an option. Probably not explaining this correctly.
If I have movieclips called "test1", "test2" and "test3" in the _root, I can use:
for(i = 1; i <= 3; i++){
_root['test'+i]._x = 100;
}
How do i use the "_root['mc']" selection method if all my test mc's are in another mc called layout.I have tried this but got a syntax error.
for(i = 1; i <= 3; i++){
layout.['test'+i]._x = 100;
}
I'm new to flex and actionscript. I'm trying to create a small flex app that has multiple states, but if I have nested containers, it looks like some of the objects are not getting initialized when I expected them to be, even when I have the creationPolicy set to "all."I've reduced the issue to a small example, with a commented block showing when it does work.sing the existing code, I get this error: "TypeError: Error #1009: Cannot access a property or method of a null object reference at main/init()" and the event handlers are not installed.If I instead use the commented block, which has the Panel and VBox elements removed, it does work.I know I could add a click attribute to the mxml elements, but this is just a simplified example, and I'm more interested knowing why the objects are not initialized when the app loads.

Here is my main code:
[Code]....
I run my code, it will give me a "Cannot access a property or method of a null object reference" error. I double checked, I realized when the program run until the component file up to the accessing dataGridData variable, that dataGridData variable is null at that time. That is probably flex initiate the component file before it send or get the xml data from server in main. Which cause the variable is still null at the mean time.
I have this custom class which extends EventDispatcher
private var assetsManager:AssetManager;
And this running on creationComplete
GeneralUtils.parentComponent = this;

I'm getting 1009 errors on the second line. I've been looking at this for a while and can't figure out what it can't find. The OnAssetsLoaded function is there.
