I would like to know if there is a way to watch / listen to variables or object properties using the eventDispatcher class ? I checked tutorials about this class and I understand basics but I really don't see how to do this..
I know the existence of the watch() function, but I heard its possible to use eventDispatcher instead...
How can I 'watch' for changes in the _width, scroll, maxscroll properties other than onEnterFrame / setInterval etc. Btw. I tryed <object>.watch but found this in the AS ref:
"Generally, predefined ActionScript properties, such as _x, _y, _width, and _height, are getter/setter properties and cannot be watched with Object.watch(). "
Why do I need this? Im making a dynamic textfield with a scrollbar that will display loaded text, but here's the catch. The site is on a single frame, and has a button that uses a resizeTo() function (a Flash extension) on the textfield and changes it's _width value. So thats why I need to update these values for the scrollbar to be accurate.
I'll try to explain my problem as simple as possible So, I have class A (main class) and class B, and I need these to communicate with each other.

This gives me the error: Access of undefined property RNDMCOLOR... but, I made it public, so it should be accessible by other classes right? Apparently, no I have also tried to type the string "rndmColor" directly into the eventDispatcher and listener, and that gets rid of the error, but the chooseColor function is never called. So what the heck am I doing wrong? How do I make variables accessible from other classes if public doesn't do it?
I am making a fighting game in Flash and while I have everything running, I am missing something: a victory/loss screen.Logically,I know how to do it:
if character.hp < 0
{
character.dead = true;
dispatchevent("death", event)
}
My problem is that I have no idea as to how to code it. I know I will use two classes and my two .fla files (unless I am wrong).I have two .fla files that are in play here: the Menu.fla file and the Arena.fla file. Menu.fla contains the entire navigation of the game, options, character selection screens, etc. and when it is time for the player to engage in battle, it loads the Arena.fla file, which contains only the backgrounds (depending on the selected stage) and for now is set to a length of one frame only. For Arena.fla, the real action happens in my classes, but logically, I would only need HP.as and Character.as.
In Character.as, I have declared the following variable:
var isDead:Boolean = false; //is character dead?
In HP.as, believe I should have the following:
if(currentHp<0)
{
currentHp = 0;
character.isDead = true; //declared as var `character:Object;`
EventDispatcher.dispatchEventListener("playerDead", playerDead);
}
And finally, in Arena.fla, I want to be able to detect the above-mentioned eventlistener and simply move on to a second frame which will display a message in the style of "PLAYER ONE HAS WON" or "PLAYER ONE HAS LOST" with a button that will allow me to go back to the character selection screen. This is the first part in which I am stuck: how do I detect the dispatched event listener in my main .fla file?
Secondly, if the player clicks on the "CONTINUE" button, which displays regardless if the player has won or lost, how can my Menu.fla (which loads the Arena.swf) detect this click event, unload the game, and go back to the character selection screen?
I have several classes with some eventListeners in my project that interfer with each other. I.e. i have a mouseclick event that is not triggered, when i have another class with init events running at the same time. when i remove that other class, the mouseclick event is triggered correctly.
now i am not 100% sure, but i think the solution to this has something to do with EventDispatcher.can anybody please tell me if that is correct and how i can add EventDispatcher to my code without recoding everything?
Is it possible to add a "watchdog" to a variable so that it fires an event if that variable changes value?
I know that I can have a loop testing every frame, but that seems unelegant.
im getting really frustrated because i can not watch any of the NHL videos on [url]......i have the latest FLASH plugin but i just get a black screen when trying to view a video. Im running vista.
View 2 Repliesi'm Creating a Game and Watch style game. Now with these games the everything works off keyframes so I've been trying to create a character that spawns in(he will first flash in over a couple of key frames, then on labeled keyframes are animations of him holding objects), then depending on a chance it will spawn either 1 or the other power up. Then you can go up to him and collect the item, he will disappear. here is some code for the idea i have for spawning, but how can i then call upon random outcomes between the two options that are 'labeled' inside the class. basical four keyframes of him flashing then four of him with a jug labeles "oil" then four of him with food labled "kabab". is it possible?

For some while I am researching on dispatching Events on AS2 which can bubble as it happens in AS3. This is not the first time in this world and I hope you all know how to do it in AS2. My issue is not on addEventListener but the removeEventListener which is not removing that particular event from that object.Cause the handler argument in the mx.events.EventDispatcher is throwing undefined where that should be [type Function]. At the time of registering on addEventListener it is registering the handler as [type Function], but it throw undefined on removeEventListener method.

Considering the above code if for example I want to broadcast the event of onLoad of xml to different listeners objects with the scope of movieClip in which the xml object is declared, so that later mcs from the library can be attached dynamically.However this approach does not seem to work.
Theory question, more than anything.
Code:
var page = _root["pageinstance"+num]; //num is a variable,
page_li:Object = new Object(); // page_listener object
page_li.onPageLoad = function() {
trace("hey, look, the page loaded");
page.display();

The code is much more complex than this, but thats the skeleton of it. Anyone, my question to you is that I need to use this over and over again, for each time the user presses a button. My problem is that Flash seems to have trouble when I try visiting a page I've already been to, because the events don't properly execute. I've tried page.removeEventListener(); and delete page_li; but both seem to be ineffective. Basically, how can I whip the slate completely clean, so that the next time when Flash goes over this code, it executes properly?

View 6 Repliesi have a class called "RandomErrorClass" that extends Error:
Code:

public function RandomErrorClass() {

my understanding is that the second class, the one that throws the error, will have to extend the EventDispatcher class. is that right? but it already has to extend the MovieClip class. my questions: Does the movieClip class already inherit from the EventDispatcher class? if so, i won't have to implement the IEventDispatcher interface, will I?
Why can't I watch youtube videos on my laptop? It's brand new. I can go to the website and the video loads just fine. It starts to play but then shortly after it quits. The monitor flickers and then goes black. I don't think it's the Adobe Flash player.

View 1 Repliesi have 5 submit buttons for example. When each submit button is clicked, a portion of the application is done. When all 5 portions are completed(or when 5 variables == true) I want something to happen.As of right now, on my submit buttons I am checking to see if all variables are true like so...
Code:
mySub.onPress = function(){

Is there a way to "watch" these variables, and when all are true do something, instead of having these conditions on my submit buttons?
