ActionScript 3.0 :: Duplicate AddEventListener Assignments?
Oct 26, 2009
Is there any harm in registering an object with the same event and handler multiple times, without first removing the listener? It appears that Flash either overwrites the event subscription or ignores duplicates. What I'm trying to avoid is having to use if/else and boolean variables to make sure duplicate event subscriptions don't occur.
I've attached a sample fla... which I'm aware looks useless, though it illustrates my point. It loops through the timeline a few time and makes the addEventListener call a few times. Clicking on the button only calls the handler once, despite the multiple assignments. So it appears to be safe and Flash doesn't throw an error, I just wanted to know if there's some sort of garbage-collection-like issue

If I have an object that calls
addEventListener(Event.ENTER_FRAME, update);
addEventListener(Event.ENTER_FRAME, update);
will that add 2 listeners?

I posted this question yesterday, with no responses, hoping for better luck today for such a vague problem. Pretty much, I have animated mc buttons, that over the course of the website interaction (various transitions) move around the site area. Unfortunately, after doing their big transition once or twice, they are animating to previous frames actionscript... in other words, if my btnA is in a differenct position due to these transitions, when I click it, it animates "from it's previous position"... does that make sense? Is there anything I can do to be sure that all previous code is dropped for the current frame code? seems odd, but there must be a way to do this cleanly?

I need to make a flash website for one of my assignments, but whenever Im try and make something, none of my action script is compiled.Ive done up a test file that it 2 frames, with a stop(); function on the first frame, no other action script. I get no errors, however it just continues to loop through all the frames. Here's the .fla:
[URL]
Another interesting this is I can type gibberish into it and I dont get any compiler errors....its as if it doesnt even look at my actionscript. Even if i purposely put and error in, nothing at all...
It has to be something Im doing when working, as i can open up other files that Ive made in my class and publish them without this problem happening...I can even edit them a bit, but after a short while of editing (im not sure when) then suddenly this problem appears in them.

Probably a lack of knowledge on my part (no, definitely...), but how do I go about loading dynamic text fields from an array, using dynamic variable naming?
for(j=0; j<count; j++){
this["contacts_mc.nameText"+j+".text"] = inputArray[j][0];
}
"nameText0", "nameText1", etc are the instance names of dynamic text fields in the contacts_mc movie clip, which is on the root level of my timeline.I get no return at all when tracing the target dynamic text field as trace(contacts_mc.nameText1.text), for example. Dynamic naming examples I've come across don't seem to work here - perhaps a difference in how dynamic text fields are assigned?

the situation | an instance of the DateChooser component reads an xml file which houses info for homework assignments and their due dates. if there is a due date, make sure that date is highlighted on the DateChooser component. from what i've been told, the xml file stores urls which will tell if there is s/thing due on a particular date. the xml file | very simple, has an <activity> element with a 'date' attribute, i.e.
[Code]...
my remaining questions | What needs to happen as soon as the xml file is loaded? i.e. do i call a function which parses the xml data and puts it into an array? then the DateChooser component iterates thru the array looking for boolean values noting if there is an activity or not and if so, on which day. if it finds one, it sets its highlight property to true for that particular day. i'm setting up the xml file correctly.

My problem is that when I click the letter movieclip it does create the duplicate as it should and it starts to drag the duplicate mc. However, when I release the clip it doesn't stop dragging? I realized that if I put onMouseUP event instead of onRelease it actually does stop dragging when I release the mouse. I would, however not like to use the onMouseUP event if possible.

I am having problems dupliating a movie clip. I can make a duplicate from an original but when I edit the duplicate it also modifies what is in the original. (I am just changing the text, thats the only difference between the 2) How come it effects both clips when I only change one?

I have a custom ActionScript class:
package EntityClasses
{
import mx.collections.ArrayCollection;[code]....
And I want to bind these values to textBoxes, so that when user types information to the textBoxes it is populated in the class too. Is Flex 3 bidirectional so that marking the class with [Bindable] I can bind the values to a textbox for example?This is my mxml file in which I try to bind the class:
import mx.rpc.events.ResultEvent;
import EntityClasses.CompanyInfo;
[Bindable][code].....
The flex compiler shows me this kind of warnings: Data binding will not be able to detect assignments to "company".

I am trying to make an interactive flash application that works by detecting mouse overs and clicks on various buttons/movie clips and then moves to the appropriate part of the time line. But I am having an issue when I use more than one addEventListener in any one frame. I have attached the code for one such frame below. When I comment out the addEventListner and the other code relating to the followBall function this works fine and directs the user to frame Inlet_Valve_Open_Frame but now only the followBall function is working and when i try to click on the Inlet_Valve_Button movie clip nothing happens.
Can someone please help. I have never read all the help files on the adobe flash CS3 as i don't have time and i have built this code up based on examples i have found online. I wanted to include my fla file but it's to big 6Mb. But i have attached the swf so you have an idea what i am doing.

If in a situation, the addEventListener is being assigned more than once for same actionwhat will happen then? Suppose on frame 5 there is ample_btn.addEventListener(MouseEvent.CLICK...... ... and when user navigates the application/site it comes on frame 5 again and again. Will the addEventListener be applied more than once on that button? If yes then what will happen on clicking on that button? will the associated function be called more than once now?

I have made the flash file into CS3 and simplified the idea a bit. Basically I want to click the box on the right to start playing the song and the spectrum and then if I click it again it will stop playing the song and the spectrum then if I click it again it will start playing again ect ect. I could not upload the song.mp3 cause the file size was too big you will have to replace it with another mp3 in the root of the folder and name the mp3 song.mp3.

I have created a scrolling bar menu. All the buttons in the menu work except for the last two. When I place a trace statement within the function it definitely is listening to all the buttons except for the last two. All instances are named correctly. Can the size of the scroller be contributing to why the addEventListener is not working?

I have this map I'm creating in Flash. You click on a state, then you can click on an icon to view a tooltip/popup of some information. What I was trying to do was instead of creating new functions and event listeners for every different icon is to use a for loop...but it's not going so well.[code]...

I currently have a .swf file that is nested into another .swf file. In the parent SWF file I use a UILoader to load the other .swf file. uiLoader.source = "data/child.swf";- In the child SWF file I have stage.addEventListener(KeyboardEvent.KEY_DOWN,keyPressedDown); and when I run it on it's own, it works perfectly; but when I run child.swf through parent.swf stage.addEvent... give me a null reference exception. Is the stage part of what is causing the issue?, and if so, is there a way to fix this?

I want to add a series of event listeners. they work fine in individual lines of code:
ActionScript Code:
home.addEventListener(MouseEvent.CLICK, route);
resume.addEventListener(MouseEvent.CLICK, route);
portfolio.addEventListener(MouseEvent.CLICK, route);
contact.addEventListener(MouseEvent.CLICK, route);
but when i use this loop, i get a 1006 error, "value is not a function":
ActionScript Code:
var buttonNumber:Number;
var buttonName:Array=new Array("home","resume","portfolio","contact");
for (buttonNumber=0;buttonNumber<4;buttonNumber++) {
buttonName[buttonNumber].addEventListener(MouseEvent.CLICK,route); }
is there something obvious that's wrong with my last line in that loop? i've narrowed it down to the part where I call the array value. but after that - I'm at a loss!

I have a for loop that loads a variety of movie clips that I want to have function as buttons. From what I've read adding an event listener is the way to go but I'm not sure how in this case. I've searched online and found a few articles that come close to what I need but not quite. Can't I just tack on an event listener for a mouse click on these objects and have it run a function I have defined elsewhere?Also in said function what code would I need to use to reference the button that was just clicked, would this. work?

I need to add an event listener to a music player script, but the button it is listening to is in a completely different timeline, and layer. (see the attached file for a crude diagram).
How to I reference this in the actionscript in the music player? Each time I try, it disables all other listners in the music player, and outputs a message; Error #1010: A term is undefined and has no properties.
