Why this event listener stops listening?

• [noob] Help understand why the event listener continues even after the withdrawal.

  Hey again,

  I'll try to do my best to explain. I can get this to work properly, but I'd like to understand why what I did before was not working.

  I have a little trouble understanding why an event listener continues listening to even after that I delete it. I have a facility where a Parent MovieClip ("CampScene") is established and an event listener is added to the look for a function ("walkUpToCampfire") to see if a condition is true ("comingFromAx is true", that won't be true until later).

  If it is true, an animation plays, an event listener is added to see if the animation is made and if it's an event listener is added to listen for a click ("campScene.goToAx") to a new animation to play and other events. (It won't be true until later.)

  If this isn't true (which is the situation that I work with at the start), the event listener said listening for a click on "campScene.goToAx" is implemented immediately. The function following removes the event listener, so it is supposed to stop listening to a click and let an animation play throughout.

  The problem is a continuous click to be listened to and if you keep clicking on the reboot of animation every time, which is what I don't want to happen.

  --------------------------------------

  I'm able to resolve the problem by adding the line "campScene.removeEventListener (Event.ENTER_FRAME, walkUpToCampfire)"; or in mouseEnabled affecting false for "campScene.goToAx", but I try to understand what is happening.

  It is, even if I'm deleting the listener ("campScene.goToAx") in a function ("goToAxScene"), "campScene.addEventListener (Event.ENTER_FRAME, walkUpToCampfire)"; continues to wait for a mouse click, unless it is removed also?

  Again, I am trying to understand how it works.

  --------------------------------------

  This should be all ACEs. Of course, I would like to know if you need more information. (I can post the FLA / AS files if need be.)

  check the label to see if axScene must appear
  campScene.guyAtCampScene.addEventListener (Event.ENTER_FRAME, addScene);
  }
  

  Your best bet to solve why things happen is to make use of the trace function.  In this case, you may have a trace run every time this listener can addedand any time it is deleted.  In this way, you should be able to see if it was added in after he deleted.  If there are several places where it is added, then adjust your tracks to indicate which line is involved as well.

• Why Event.ENTER_FRAME cause this code to stop working? Is there a better alternative?

  I programmed the code according to a table of buttons

  can be dragged on the screen when either:

  var buttons: Array = [button1, button2, button3];

  for (var i: uint = 0; i < buttons.length; i ++)

  the buttons [i] .addEventListener (MouseEvent.CLICK, alignButtons)

  alignButtons function (e: Event)

  {

  for (var i2:uint = 0; i2 < buttons.length; i2 ++)

  if(Buttons[I2]!=e.Target) {buttons [i2] .x = e.target.x ;}

  }

  for (var i3:uint = 0; i3 < buttons.length; i3 ++)

  keys [i3] .addEventListener (MouseEvent.MOUSE_DOWN, buttonDrag);

  function buttonDrag (e: Event)

  {

  e.target.startDrag ();

  e.target.addEventListener (MouseEvent.MOUSE_UP, buttonDrop);

  function buttonDrop(e:Event)

  {

  e.target.stopDrag ();

  }

  }

  It works pretty much I want to it works, except for the fact that I have to click the mouse to update the screen. However, when I change the first "MouseEvent.CLICK" to "Event.ENTER_FRAME" event listener code goes haywire. Is there an another event listener that I use here?

  Due to what seems to be an incomplete set of braces, it is difficult to tell how much nesting you have there, but it should be none.  Each listener and handler function must be able to stand on its own.  You should not have to put all the functions inside a loop.

  With the CLICK event listener is unnecessary if you have a MOUSE_DOWN and a MOUSE_UP because a followed MOUSE_DOWN to a MOUSE_UP is a CLICK.

  If your goal is to have the buttons all are linked together around x-wise, so that you can do is assign a MOUSE_MOVE event listener at the same time you run the startDrag and use its event handler for button positions.  When you stopDrag, you also remove the MOUSE_MOVE listener.

  The extent of why things go haywire when you change using an ENTER_FRAME, you must show the code when it is in this form so that any error is obvious.

• Why add a listener for an Event object?

  Hello

  
  

  I just read something that I do not understand in a book and, of course, I need help...

  
  

  stage.addEventListener (MouseEvent.MOUSE_DOWN, clicSouris);

  function clicSouris (pEvt:MouseEvent): void
  {
  var positionX:Number = pEvt.stageX;
  var positionY:Number = pEvt.stageY;
  monDessin.graphics.moveTo (positionX, positionY);
  pEvt.currentTarget.addEventListener (MouseEvent.MOUSE_MOVE, bougeSouris);
  }

  function bougeSouris (pEvt:MouseEvent): void
  {
  var positionX:Number = pEvt.stageX;
  var positionY:Number = pEvt.stageY;
  monDessin.graphics.lineTo (positionX, positionY);
  pEvt.updateAfterEvent ();
  }

  
  

  My question is what appens when I add an event listener for the event of the object? And why it does this?

  
  

  Following the logic with the AS3 display list, I thought that only Classes that inherit from flash.display.InteractiveObject might react to events from mouse (or keyboard).

  
  

  You can subscribe itself in any event an event? Am I wrong?

  
  

  Can someone explain to me this point because I'm really confused!

  
  

  Thank you!

  Basically function clicSouris is in itself an event listener and has pEvt as event event object argument.

  When you call .currentTarget pEvt it refers to the current object where the pEvt event is dispatched.

  Event.target and Event.currentTarget will always return the interactive objects where the event is currently being distributed.

• listen to this device has stopped working

  "To listen to this device'-> 'reading through this device' randomly stopped working.

  I had it works perfectly for a week and then I have to restarted and it has stopped working. I was using onboard speakers that has a stereo mix and stereo mix parameters used to send audio to my USB headset for I can get the sound from the speakers and my helmet.
  Listen to this device does not work on my stereo or even mix my microphone to try to listen to it on any audio device.
  I tried to restore my computer to a point to where he was working, because I think that this was due to an update of windows. I also tried to uninstalled the audio drivers and the installation of new, install the 'old', everything.

• ActionScript 3 - several variables for event listener.

  OK, I have a question (of course this is the reason why I'm here).  I put emphasis on PHP a lot lately and just had a customer who requires an MP3 play several songs so I had to whip on my rusty actionscript skills.  I have the complete player and it does not work as you wish.  The downside is that there are several pieces.  I use separate functions for each song and separate event listeners.  My main question is there a way to combine these functions into one and just use the event listener to pass another variable to functions?  Here is a sample of one of the code for Song1.  I would like to do so anywhere there is Song1 in the code, I can make a variable so I can put for example (Song2, Song3, Song4, etc..)  In this way, I can have one or two functions to manage all the songs instead of having to copy, paste and then search and replace.

  Thanks for the help!

  // Song 1
  var Song1:Sound = new Sound();
  pbSong1.source = Song1;
  //pbSong1.visible = false;
  var Song1Loaded:Boolean = false;
  
  pbSong1.addEventListener(Event.COMPLETE, Song1LoadComplete);
  btnSong1Play.addEventListener(MouseEvent.CLICK, Song1Play);
  btnSong1Stop.addEventListener(MouseEvent.CLICK, Stop);
  
  function Song1Play(event:MouseEvent) {
       if (Song1Loaded == true) {
            sndchnlMain.stop();
            sndchnlMain = Song1.play();
       } else {
            pbSong1.visible = true;
            Song1.load(new URLRequest("media/music/Song1.mp3"));
       }
  }
  
  function Song1LoadComplete(event:Event) {
       trace("Size of file: " + Song1.bytesTotal);
       Song1.close();
       Song1Loaded = true;
       if(sndchnlMain) {
            sndchnlMain.stop();
       }
       sndchnlMain = Song1.play();
       pbSong1.visible = false;
  }
  

  You can code

  function SongPlay(event:MouseEvent) {var songNum:int = Number(event.currentTarget.name.split(btnSong).join("").split("Play").join(""));      if (SongLoaded) {  // use one booleanSongLoaded=false;           sndchn.stop();  // use one soundchannel
           sndchn = this["Song"+songNum].play();
       } else {
            pbSong1.visible = true;
            this["Song"+songNum].load(new URLRequest("media/music/Song"+soundNum+".mp3"));
       }
  }

• Keyboard event listener does not work in the browser

  Is there a reason why a keyboard event listener would not work if the flash is embedded in an HTML element? The rest of my game runs well in the background, but I can't launch the movieClip "nextCar." My code is below, if that makes a difference...

  goNow function (event: KeyboardEvent): void {}
  thisOtherKey = event.keyCode;
  If (thisOtherKey == 32) {}
  nextCar.gotoAndPlay (2);
  parkingQue.play ();
  tent ++;
  }
  }
  stage.addEventListener (KeyboardEvent.KEY_DOWN, goNow);

  This is perhaps a silly question, but have you tried to click on your swf file once it opens in the browser and then try the keyboard controls?

  I don't know any problems that may cause debugging workwhen event listeners, but not in a browser.  So I think that maybe your just not well centered on the swf.

• event listener confusion

  I tried not to do something weird with eventListeners to date. I have a movieclip with several images I use on him attach a textfield. problem is that I have an eventlistener for when the mouse rollsover the movieclip to go to section 3 of the movieclip.
  
  Here's my function
  function doOver(evt:Event) {}
  evt.target.gotoAndStop (2);
  }
  
  However, it is throwing the error
  
  ReferenceError: Error #1069: property selected flash.text.TextField found on and there is no default value.
  at Menu_fla::MainTimeline/doOut()
  
  What is causing the textfield object to take it all at once and how she stop. When I trace the evt.target - it's my movieclip.

  Hi bluegenie_Sa,
  the event.target always refers to the hurried istance the event, in your case the istance textField. But if you want to refer to the movieclip containing the textfield in the listener function, you must use evt.currentTarget instead of evt.target. Because of event bubbling... but it's a long story... clearity evt.target always refers to the component that sent the event. evt.currentTarget refers to the distance that is listening for this event.
  I hope this could help ya!
  Bye!

• Problem adding an event listener

  I'm new to Flex, but I try to learn to use with Apollo. I can't understand how to add an event listener for my component MX:HTML. (I think that this component is only for Apollo, but I can't seem to work for event listeners components!)
  
  When the MXML file begins to run, it adds the event listener:
  
  htmlcontent.addEventListener (PropertyChangeEvent.PROPERTY_CHANGE, golink);
  
  It should call the golink() function every time htmlcontent.location change (the URL of the HTML component), but it does not work.
  
  The program compiles, but never runs golink(). Why it won't work? Is there another way to add event listeners?
  
  Function of the event:
  private void golink(e:PropertyChangeEvent):void
  {
  ShowMessage ("goLINK!");
  If (textinputurl.text! = htmlcontent.location)
  {
  ShowMessage ("goLINK!");
  textinputurl. Text = htmlcontent.location;
  getCurrentCard;
  }
  }
  
  HTML element:
  < mx:HTML id = "htmlcontent" x = "0" width = "100%" y = "0" height = "100%" location = "main.html" visible = "true" / > "

  See the documentation for the component html again. I think it's locationChange is the event you want. I just looked at this component today, but don't have the documentation in front of me now. But I remember reading something like this. The propertyChange event is very generic; you are looking for something specific.

• ERROR: Adding an event listener to a button in the main scenario

  I'm trying to get a simple script to work temporarily to show features. This file is a menu.swf file that loads below content.swf.
  
  There are 4 buttons on the main timeline and a stop at frame 40. On the same layer that my button is and frame 40, I have this code under actions. dineContent is the instance name of the button that I am referencing.
  
  However, I get access error 1120 property undefined.
  
  I know that I can add an event listener to an instance name. I have to create a film about all these buttons and then reference the instances of button inside the movie?
  

  I started playing with a bit more and found the solution.

  SOLUTION:
  in the property inspector to my instance of dineBtn named "dineContent", there is a contextual list under the "instance of: _" txt where you can choose between the track as button or Menu item.

  You must use the track as Menu item. the default value is button.

• Add the HTTPService call event listener

  Hi, I use a HTTP service in my flex application.
  My HTTPServeice connects to an XML file:
  
  
  < mx:HTTPService
  ID = 'myResults '.
  ' URL =' http://localhost/myResults.xml '
  resultFormat = "e4x".
  result = "resultHandler (Event)" / > "
  
  the data in the XML file are constantly changing (the structure remains the same, but changing the actual data in the structure of the XML), so I am refreshing my HTTPService results every 5 seconds:
  
  [Bindable]
  public var myDataFeed:XML;
  
  private function initApp (): void
  {
  var timedProcess:uint = setInterval (refreshResults, 5000);
  }
  
  private function refreshResults (): void
  {
  myResults.send ();
  }
  
  private void resultHandler(event:ResultEvent):void
  {
  myDataFeed = event.result as XML;
  }
  
  
  My problem is that sometimes the XML file needs more than 5 seconds to load / refresh the data (as it is quite heavy) etc... that is why I want to implement some sort of event on the HTTPService listener to notify the application when the results have been refreshed so I can limit / 5 seconds refresh taking place until the previos refresh is complete etc...
  
  is it possible - to an event listener for an HTTPService to know when it has finished refreshing results to an XML file?
  
  Thank you
  Jon.
  

  Instead of having a timer object runs the service every 5 seconds let the service itself run itself once the result is successful.

  Both in the
  private void resultHandler(event:ResultEvent):void {}
  myDataFeed = event.result as XML;

  couple options-
  1. call the service again... maybe build a kind of late here.
  2. run another object that has a delay, then runs the service
  I work late here because put the send here will keep your communications with your server constantly active.
  myResults.send ();
  }

  All you need to do is run this service on the initialization of the application and will continue to call itself.

  However, I think you may have a fundamental problem with two approaches that your communication with the server is constant. If you need to make other calls to the server, for example to save data or fill out another form, you need to manage your connections.

• How can I create an event listener for the change of variable shared or similar?

  Hello

  I have a 'big' 6 devices communicating measurement system via the TCP protocol. The system is designed to use REST (the representative State transfer) with JSON (JavaScript object notation).

  Now, I need to add labview program to this environment. I've implemented a solution to 'work' with the help of this forum. Thank you for this! Now, I need to do better (currently no timestamps, large delays, etc.).

  I currently have a web service deployed using http-get as input. My web service .vi is just passing the web entrance to shared variables that are then questioned in real measurement program. Reason is that when I put the measurement program directly to the web service, it does not (something about rights and dependencies). Measurement program includes one third of the owners (Instron) drivers. Also I would not direct access via the network to our mechanical testing device potentially dangerous.

  Now, I want to change the message from the web services .vi commensurate .vi. Currently I have a loop of 10ms to query for changes in the shared variable. Is there a better way to do this? I thought create a listener to the shared variable change events.

  In addition, if you have any ideas (preferably, working code example) how to make the interface between labview and TCP-JSON I would really appreciate it.

  BR,

  Juha

  Currently in LabVIEW, the only way to create an event listener or event NSV is to use the DSC toolkit.  Most of the time the DSC is a very expensive tool that simply encapsulates the functionality that is built into the motor of the PSP and OAS and which is accessible to anyone who can program in LabWindows/CVI.

  http://zone.NI.com/reference/en-XX/help/370051P-01/CVI/libref/cvicnvcreatesubscriber/

  If you want to collaborate, I would like to create a small library of LV that would create a base SV events using a vi LV reminder or possibly passing return user LV event which is how works the DSC toolkit.  I asked OR several times to explain how do this and they're very tight discreet about it.  I guess that they do not want to give users LV less reason to buy the DSC.
