Does creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?
View 1 RepliesI am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.
View 3 RepliesI am wrapping my brain around OOP in AS2. I am making two posts on two different subjects. My question here is: when should I use local instance variables, and when should I attach new properties to the instance object? (Feel free to correct my terminology.) Let's say I have a class for a scrolling background, which scrolls when I mouse over its edge. I want to put these values somewhere:
1) How wide is the border in which a mouseOver makes it scroll? This is basically a semi-constant I set it up once and keep it the same, unless the user changes it in an options menu to make the border wider or narrower. Call this scrollBorderWidth.
2) How fast is the background scrolling now? I want to track this so I can smoothly change the scroll speed over several frames. This is often changed. Call this scrollSpeed.
It seems I have two ways I can store and access these values and darned if I know which is better practice. METHOD A: Make them local variables in the class, so the scrolling background instance has them as local vars. I set them up thusly:

How to trigger a custom jQuery event from Flash, passing some data through event object?
View 2 RepliesI have a button which is an instance of a "button1" class. The button is instantiated by an instance of the"introScreen" class which is instantiated by the "screenHandler"class. I'm not sure how to attack getting an instance(the "button1" instance ) to dispatch an event heard by its grand parent(the "screenHandler"instance). My main confusion is getting an instance to transmit a specific event like the name of the screen to switch to. Can I specify a custom event in an instance?
View 2 RepliesWhen I use MouseEvent.MOUSE_OUT the target is [object MovieClip], but when I use MouseEvent.ROLL_OUT I get [object Bildspel] - and Bildspel is my class. The thing is that when I use ROLL_OUT I'm not able to delete the targets ENTER_FRAME event.

Alright, I've looked online at a bunch of different collision tutorials but they don't explain what I'm looking for. I want object A to hit object B and then execute a function via to a Event listener.
View 1 RepliesI want to listen for a custom event dispatched from the document class in a custom subclass. For example, let's say in the document class I have:
ActionScript Code:[code]....
So that the subclass will trace 'Event from document class received' when the 'customEvent' event from the document class is listened by the eventlistener. However, the output is only 'customEvent dispatched', meaning it wasn't heard in the subclass.
i created couple instances of movieclip with some simple animation inside, want it to animate when mouse is over, and animate backwards when mouse is out.[code]it works better, only one instance move, but if i move mouse over second instance before first one finish moving back to the first frame (and remove listener), again both instances animate together, like they are using the same timeline.
View 3 RepliesHow do you disable only the MOUSE_OVER event for a an instance of the Button class in AS 3?
MyButton.Mouse_OVER = null ;
Will not work as it is not a writable property.
MyButton.enabled = false
Will not work as that disables the entire Button and that is not what I want.
How do I access an object (in this case a button) within an instance of a movie clip on the stage?Basically I want to listen for a button (but_1) within the movie clip instance (menu_bar_1) which is set on the stage of my main movie.I want to use that same movie clip in several different parts of the main file, and each time the button will play a different sound.

I'm fairly experienced with Flex 4, but I still haven't needed frameworks yet (I like to do everything myself) and don't want to use them either, I know it's advantages and have learned how to use one of them, but still, no.
How can I dispatch an event in the main application and have a component inside a popupmanager to react to that event? All this dispatching the event within the main app and NOT aiming it to the popupmanager or the component instance, I want to be able to fire the event and not care about who gets it or if anyone reacts to it at all so if that is possible then I wouldn't care about keeping track of said popups.
I already dispatch an event from the component and receive it in the main application by bubbling the event and therefore being agnostic of each other, now I want it backwards.
Is it possible to access the type of object being interacted with so I can create a new instance of the same object? So for example in the code below I have the movieclip myItem. After it's clicked it is removed from stage and then moved to the inventory. When I click on it there, is it possible to create a new instance of mcItemToDuplicate using the event information parameters? (while allowing myItem to be where it is).
My code looks something like this:
public function moveclip() {
var myItem:mcItemToDuplicate = new mcItemToDuplicate();
stage.addChild(myItem);

I've been searching this forum and googling for quite some time, and I haven't been able to come up with anything. Anyway, here's a description:I have an array that has multiple instances of the same movie clip. I add them to the stage and then add an eventListener to each one.I have that working fine. The problem is, I'd like to add a filter to them and remove an eventListener once the eventHandler has been activated. However, I have no way to know which instance set off the eventListener. Is there any way I can pass that information into the eventHandler function? Or is there any way I can access the parent from the evenHandler itself? [code]
View 3 RepliesI was wondering if I had say 10 buttons and I wanted to add them to one event listener, is there a way to set up an array and attach them all to one event listener to cut down on code?
View 1 RepliesI need to find an instance of a movieclip that is on my flash file. It is really big and uses a lot of memory. It says on the number of times used that there is one instance of the object on the flash file, but I can't find it. I thought I deleted them all but there must be one left. How do I go about finding it? It's a really large flash file with many layers, and I don't want to just delete the library file. Is there any way I can find where the object is placed in my file?

View 10 RepliesIf I pass a MovieClip through as an argument in the constructor for a class I am writing, how do I create a new instance of that MovieClip from within the class?
The MovieClip has a custom class name that is unknown to the class I am writing, it is simply passed through as a MovieClip.
I tried:
Code:
_class = Object(mc).constructor;
_mcArray[i] = new _class;
I have a graphic or movie clip as an example which is a water bottle. An what I wanna do is that depending on what is the user response, in my case is how long the person is doing some activity, depending on that I want flash to generate a number of graphics/movie clips on the screen. As example the person says that takes 6 minutes doing "x" activity, so as a response of a button click which says "generate consumption", it generates on the screen how many water bottles he has consumed for that range of time doing that activity, for example each minute is 2 water bottles, so it has to generate 12 water bottles on the screen when the user press "generate consumption".

removing object instance from memory.I have created a class that move objects(movie clip) on stage. and on fram 1 i created 100 instances of this class using loop. now when user click on movie clip it should be remove from stage as well as from memory. using removeChild() it is removed from stage but it is not removed from memory. for testing i use initialy only one instance to check my code and when click it is removed from stage but not from memory. here is the code
// this code is on frame 1

i used delete and assigning null and GC but nothing works. any one who knows how to remove the object instance from memory I applied every thing but object instance is still in memory (because there is a trace in fall class which continuously running and i guess the object still exist in memory)
I`m having a silly problem with adding instance of an object to the stage two or more times. For example, this don`t work:
Code:
var temp0:SomeClass = new SomeClass();
this.addChild(temp0);
this.addChild(temp0);
Well, I know that one instance is one instance and two objects of the same class on the stage would be two instances, but still, it is what I need.
is it possible to dynamically change one instance of an object without effecting the others? I've created an input text field in the library and when the user hits the "add text" button, it adds an instance of the input text field to the display list. They can then format the text how they wish (color,alignment,etc..). When they hit the "add text" button again, a new instance of the input text field is added to the display list, but when they try to format the new input text field, all of the fields are effected. How do I get around this?
View 2 RepliesI mean the value returned by:
trace(e.target.name); (tried on a MouseEvent object)
or
trace(myTextField.name); (on a textField object).
In my Flash application, I notice that tracing the name of an event object returns "instance26", indicating that this is the 26th (or 27th depending on the base of indexing) object created since the app initialized. Basically what I'm curious about is, firstly, is this instance value subject to change when the app is ported to other platforms (if different versions of the Flash player process instructions in a different order or fashion) and secondly, how can I find what object contains "instance0" or (if the instance indexing begins at base 1), "instance1"?
i'm going in trouble with instance names, classes, methods, and addChilded object...
that's my code:
- i have a class that (everytime the function is called by the timer) add an object(class "Monster") to the stage.

I also tried to avoid the problem changing my point of view; so i inserted the hitTestObject test into the loop for each ( var enemy:Monster in army ) but the same problem occurred, i have a lot of balls that doesn't have an instance name (or they have all the same one).
This is what i created until now [URL]
