I have a swf that has key listeners listening for specific key strokes. This works fine until I load the .swf using the loader class. Do key listeners still work within loaded .swfs? Do I need to do something to the event bubbling phase?

View 8 RepliesI'm trying to dynamically load different MovieClips based on user input. Several of those clips have embedded url link symbols. How can I add event listeners to the url links if the dynamically loaded MovieClip does not have an instance name? Seems like I can (right?) apply an instance name when the clip is loading, but the event listener doesn't compile because the name is not there yet, so that seems out.
View 5 Repliesi made a SWF which contains a loader which loads any SWF file passed to it... the problem I'm encountering is that for some SWFs, some event listeners doesn't fire anymore... my own SWF file (which contains the loader) doesn't really have any other element except for the Loader object and so I cannot understand what seems to be preventing the loaded SWF (loaded by my Loader) from receiving some mouse events
it seems that the for the SWF where I'm having this problem, the listener seems to be tied up to a location in the stage or somewhere else, and so whenever I resize, the listeners is not responding on the right place, for example, the button appears on a certain position but the listener's hit test or whatever the SWF is using to detect the mouse click is positioned somewhere else
I've created a drop down list and populated it with dynamic buttons. (I made a DropDown_btn class with a dynamic text field in it and then filled the button text from an xml file). On rollover I tint the button blue and then set the tint back to black on rollout. When you click on the button I'd like it to stay blue until a different button is clicked.
I thought on CLICK I'd run a function like this:
ActionScript Code:
function removeRollover(evt:MouseEvent):void {
evt.target.transform.colorTransform=c;
evt.target.removeEventListener(MouseEvent.ROLL_OUT, btnOut);
evt.target.removeEventListener(MouseEvent.ROLL_OVER, btnOver);
}
...and then I need to addEventListeners back to any button that doesn't have them and set that button back to black. I could do this by looping through an array of the buttons but I can't figure out how to access them as objects.
I also gave them each a property of "buttonValue" when I loaded them so I can access event.currentTarget.buttonValue (which in this case is a number from 1-5) but once again I can't figure out how I might leverage this information.
I have two components in my movie,how to write out the code for the listeners.Is it possible to write one listener that listens for changes in both components or do I have to write a separate listener for each? How would this look like written out?

I'm trying to take full advantage of the movieClipLoader along with listeners. But my callbacks aren't getting triggered. Inside one function I loadClip, when onLoadComplete happens I set the onRelease function. Within that onRelease I call another function ("cdPress") that also loads bigger images inside a clip.None of the callbacks in the cdPress function are working. The function is being called successfully, but the "onWhatever" callbacks are not.

function someFunction(){
cdListener.onLoadComplete = function(target_mc) {

I think this is in the wrong forum... sorry! Should be AS3) I am trying to dynamically create listeners using metadata from a list of instance names in an array. Here is my code:
[Code]...
So I've gotten into using my own as Classes, and have an interesting question.
My main swf calls a php script that gets data from a mysql database which is returned as XML. Part of that data that is retrieved is a filepath to a jpg image. It then takes that filepath and other information, and passes it to my external class, the "news story" class.
All fine and good. Then, the "news story" class uses a loader to load that image along with some text, organize it, and voila, you've got your own very pretty "news story". (I'm extending the MovieClip class here, though I suppose it doesnt matter)
Now, my main swf uses this component to load multiple of these "news stories". The problem is, theres that load time for the image. The main swf is loading them all one at a time, because they are putting each one together on their own.
The key here is that it be dynamic. So, since we don't know how much text is in each "news story", we also therefore don't know it's height. What I'm doing is creating each story in the main swf, pushing it into a "news story" array, adding an event listener to each ones' loader, and when the event listener is triggered, I want it to go to the 'add content' function where it sets the news story's Y value based off the position and height of the previous story that was added (stacking them, obviously). This makes sense, because otherwise it'd add them all on top of each other and it'd be a jumbled mess.
The problem is, the event listener is on the loader object INSIDE the component actionscript. So, how do I figure out which news story to set the Y value for? Because the eventlistener is listening to the loader, not the class. I hope this makes sense AT ALL. Here is the code:
Quote:
while (fancy shmantzy conditions)
{
/*creates the news story and passes xml data to it (filepath, etc)*/
storyBlock = new StoryBlock(a bunch of parameters);
subCBArray.push(storyBlock); //array that stores each news story info

In AS2 you could add an onRelease to multiple buttons like this:
Code:
onebutton.onRelease = anotherbutton.onRelease = lastbutton.onRelease = function() {
//do something when either button is pressed;
}
Is there something similar possible in AS3 using addeventlistener? Besided copying the same addeventlistner line for all individual buttons?
Lately I've been twitching in the back of my head wondering just how many references to objects that I'm making, and whether or not they are getting GC'd or not.My question in this sense refers to event listeners and whether or not they are removed in certain cases where you get rid of an object. Two examples:
First, and I think this one is an easy one... when you create an object that adds an event listener to itself INSIDE it's own methods (e.g. this.addEventListener(e:Event, function)), when you REMOVE that object (this), do it's event listeners disappear too? I can only say yes, because they are referencing THAT object and are INSIDE that object.
So I think that question answers itself (but I'd love to know if the truth says otherwise).
But secondly, if you add an event listener to an object from a sibling or parent object, and then remove the object, does that event listener stick around, therefore maintaining a reference to that object and keeping it in memory? And is that the concept that people keep referring to of 'weak' event listeners? E.g. someChildObject.addEventListener(e:Event, function)Also, are event listeners by default strong or weak?
And I am assuming that 'yes', it DOES keep the reference. Which, if you are a n00b programmer like me, you probably are all like, 'aww sh*t damn, how am I supposed to make sure that my objects are getting thrown in the garbage collector's mouth of goodness every once in a while?
Is it possible to check if an event listener already exists
like at some point in the code I write:

I found this code for a contact form at[url]...and it dynamically creates input fields and buttons.

View 2 RepliesI have a movielcip (A) class in which I have used a Tween class effect on a child movieclip (B) scrollRect. The (B) Movieclip in turn has several movieclips whose have tween class effect being executed on thier child movieclips.the tweens are all unique to each movieclip and the event listeners are taken off once completed.This works all well and good in FLASH IDE..My problem arises when I try to view this in a browser on a Windows XP.[code]
What is happening in most cases it that the animation appears to "stick" but i think what may be happening is the listening or removal of the event listeners. The animations are left incompleted.Is there any rule of thumb when using multiple event listeners?[code]the effect disables and re-enables the buttons when its done.... then the listeners are removed.each one with the exception cretes its own unique tween (obviously this is a custom class built as each clip)
If you have multiple event listeners running, is there any way to remove all of them at once rather than one at a time?

I have an array that returns multidimensional data from an mysql database, when this is collected the createNews function creates the user interface.

In my Flash project I have a movieclip that has 2 keyframes. Both frames contain 1 movieclip each.
frame 1 - Landing
frame 2 - Game
The flow of the application is simple:
User arrives on landing page (frame 1) User clicks "start game" button User is brought to the game page (frame 2) When the game is over, the user can press a "play again" button which brings them back to step 1
Both Landing and Game movieclips are linked to separate classes that define event listeners. The problem is that when I end up back at step 1 after playing the game, the Game event listeners fire twice for their respective event. And if I go through the process a third time, the event listeners fire three times for every event. This keeps happening, so if I loop through the application flow 7 times, the event listeners fire seven times. I don't understand why this is happening because on frame 1, the Game movieclip (and I would assume its related class instance) does not exist - but I'm clearly missing something here.
I've run into this problem in other projects too, and tried fixing it by first checking if the event listeners existed and only defining them if they didn't, but I ended up with unexpected results that didn't really solve the problem.
How do I define my own event listeners in AS3?
View 3 RepliesI have a basic question about manually removing event listeners in actionscript 3.If I have a function like:
private function doStuff(event : Event):void
{
//let them save
var f:FileReference = new FileReference();
[code]...
How do I remove the event listeners when the saveDone function is called? Normally I just change the "add" to "remove" like:
f.removeEventListener(Event.COMPLETE,saveDone);
However, f is a local variable, and I can't get to it after the doStuff function ends.
private function saveDone(ev:Event){
f.removeEventListener(Event.COMPLETE,saveDone);
}
How do you know when you should remove event listeners? For example, I know that if I have a TimerEvent listener, I can safely remove that event when I have stopped and / or deleted my timer. Or, if I have a display object on the stage, and I remove it, I can safely remove any event listeners associated with the display object.

Im sure this has been asked a million times, so forgive me but I cannot seem to find an answer or my search query is wrong. I am using Tweener for animation.
I have 2 MC's on my stage. I have an event listener for my main MC (MOUSE_OVER, MOUSE_OUT) that triggers Tweener to animate another MC on top of the main clip. The problem is that when it overlaps the listener no longer works, and tried to execute the MOUSE_OUT. I understand why its not working, I just cant find a solution. Here is the code and a simple FLA.
ActionScript Code: import caurina.transitions.Tweener;
square.addEventListener(MouseEvent.MOUSE_OVER, RollItIn, false, 0, true);
square.addEventListener(MouseEvent.MOUSE_OUT, RollItOut, false, 0, true);
function RollItIn(evt:MouseEvent):void {

How do you set up a funtions to run only when two or more listeners have been activated?For example: if one listener is waiting for a file to be loaded and another one is waiting for a display object to fade out.I want to get the object starting to load but also want to start the image on the stage to fade out at the same time.I want a new image to start to fade in but not before the new image is loaded and the old image has faded.
