Actionscript 3 :: When Does Local SharedObject Triggers Event Handlers Added Via AddEventListener
Jan 26, 2012
Could someone explain when does local SharedObject triggers event handlers added via addEventListener?I have tried and it doesn't trigger, after flushing.For example i have two object.swf both in separate browser tabs.I'm adding data inside object.swf on one tab and want event to be triggered in object.swf from another tab.Is it possible with native functionality and without remote type of SharedObject?Ofc i could write infinite loop and check local storage for changes, but it's the last solution i would like to implement.I was reading docs and played with example over there, but it doesn't trigger event, even if it is added before flushing.[code]
I'm using FLCS4 (AS3) and I've built a very basic site, simple pages on various frames. Three of the frames/pages contain video components that auto-play a flv clip.What I'm asking is it possible to know when the video clip is finished and at that point display a button.(So the user cant proceed forward until the video clip is finished playing){captive audience, so to speak}Anyways, is this possible, if so; how do I approach it?
Is there a way that i can access Local SharedObject using a swf from the net.
For example, i have a .swf that creates SharedObject running locally on my desktop computer.. But when i'm somewhere else, i need to access some of the shared objects in my desktop, is that possible?
I have a website where under a single domain (and in a single folder on a web server) - two flash movies are stored: MOVIE1.SWF and MOVIE2.SWF Is it possible to access local SharedObject set by MOVIE1 by MOVIE2? What I do:
My Flex app uses local SharedObjects. There have been incidents of the Flash cookie getting corrupt, for example, due to a plugin crash. In this case SharedObjects.getLocal will throw an exception (#2006).
My client wants the app to recover gracefully: if the cookie is corrupt, I should replace it with an empty one. The problem is, if SharedObject.getLocal doesn't return an instance of SharedObject, I've nothing to call clear() on. How can I delete or replace such a cookie?
I'm doing a small webapp where I want to use a fairly small amount of Local Storage for SharedObjects.The challenge is to cater to all visitors, including those that might have turned down their local storage allowance to 0 bytes (inactivated).Now, what happens is that the first flush method call triggers the local storage dialog box.In the case that the user has inactivated local storage, I don't want to ask them to raise it - instead I want to avoid using SharedObjects for the remainder of the session.I haven't found a way to test for the capacity of the local storage. What I can find is the size property of the SharedObject class. This doesn't work however as it only reports a size greater than 0 if there has already been an object written to this application domain.
it loads an external .swf file and is supposed to play it. I've added an event listener to run when the file is loaded. The function it calls moves the video to the bottom most layer so the buttons still show and then plays the file. The problem is the event listener never triggers.
I ask because I caught this at the end of an Adobe developer guide:
Notice that some properties are assigned to the [AsyncToken] after the call to the remote service is made. In a multi-threaded language, there would be a race condition where the result comes back before the token is assigned. This situation is not a problem in ActionScript because the remote call cannot be initiated until the currently executing code finishes.
But I could not find any information on what they meant by "currently executing code".
I noticed that in anonymous event handler this is referenced to global, not my class. I know that I can use outer referenced variables (because it creates closures), but how to get right this context?
My project has a target object (center of stage) and a moveable object, which is created each time a user presses "Enter". Each movable object is identified as part of an array (i.e., object[i]), and a new line (i.e., line[i]) is dynamically drawn from the center of the newly created object to the center target object.
Basically, as the object is dragged around the screen the line is to stay connected to the target object. Therefore, that specific line for that object being moved must be redrawn using a drawLine function inside the event handler. My issue is how to get line[i] to be identified within the even handler? (Using AS3 coding)
How should I comment an event handler param?I mean, should I comment event handler param?Example:TimerMessage class extends Timer.TimerMessage class, has a setMessage method, which stores a text message whithin its public var 'message'.in usage:
var timer_message:TimerMessage = new TimerMessage(1000, 1) timer_message.setMessage('hello') timer_message.addEventListener(TimerEvent.TIMER_COMPLETE, displayMessage)
What methods do you use to unit test event handlers, particularly if they require information from the event (such as mouse coordinates, or the target of the event)? Is the most common practice to just refactor the behavior into a method that does the lifting while the handler just extracts information from the event, or are there effective ways to simulate event dispatch in FlexUnit or Fluint?
I came to AS3 from JS world, and I should confess that anonymous functions are my weakness. I tend to use them everywhere. Now, coming to AS3 I've heard and read in lots of places, that AS and Flash are enormously bad at handling garbage collection, that one should empty, dispose and remove all event handlers and objects manually to avoid weird and unexplainable memory leaks and crashes. Not sure what part of this is true, but I would like to follow best practices right from the beginning. How bad is idea of using anonymous functions as event handlers? Consider for example a code like this:
Ccontorls.elapsed is the setter, which apart from setting current play time for video player, updates the whole UI, and stream is NetStream object, which streams the actual video. There are lot's of other places where anonymous function may make code cleaner and more intuitive. Check the following code for simple fade-in effect for the control bar:
public function showControls() : void { var self:Controls = this; if (!visible) { visible = true; fadeTimer = new Timer(30, 10); [Code] .....
I totally like how it looks and fits into the code, but I'm concerned about leaks. While Event.ENTER_FRAME handler probably would never become harmful in this form, what about timer listeners. Should I remove those listeners manually, or they will be removed automatically, as soon as I set fadeTimer = null ? Is it possible to remove listeners with anonymous functions properly at all?
i have an odd issue and i know almost nothing about AS3 so im a complete noob please bare with me. I am working with a template .fla for a page flip but i am using a different navigation system for the flipping of the pages. I have worked through all the errors and output problems and i can get the system to work but the moment i try to use other event handlers for the same item it completely blows up the main script to make the page flip that is required. No errors, output problems etc, it just doesn't work. So here is the code.
Is there a way to achieve what i'm trying to do here? Obviously it doesn't work this way because only the last event handler is activated and the first one is ignored.
trying to create a menu dynamically from an array. I know there is a way to circumnavigate the issues i am having by making another array with linkNames in it (i think), but im trying to understand why this isnt working. Check this out.
Code: var playerArray:Array = ["THIERY","FIGO", "RONALDINO", "WAYNE"]; var contents:MovieClip = this.createEmptyMovieClip("contents", this.getNextHighestDepth());[code]....
'currItem.currVar', in my eyes, should be assigned the value of 'i' at that time in the loop, then move on to the next currItem right? Tracing 'currItem' traces 'menuItem. menuItem'+i to the output window fine, so im assuming that currItem is indeed a reference to a unique clip to which assign an action. The catch is, its not assigning the action I want, its assigning the value of 'i' at the end of the loop to all currVar's.I recently read a post explaining this conumdrum, stating that "variables are not "burnt" into functions when they are placed there. They will reflect the variable, where ever it may exist at the time it was requested, not at the time the function using that variable was defined," but in this case,since I am assigning the value of 'i' to anothing variable inside my dynamic movieClip.
I'm trying to rewrite a procedural ActionScript program as an OOP one: in the procedural version I set up event handlers for movieclips on the stage with a loop and it worked fine.However, when I put these event handlers in a class definition, it's no good. Simplified version below, which is just supposed to make a sound when the user clicks on the boxclass definition:
class Event_stuff { var nLpCntr1:Number = 0; var nNumberOfChoiceBoxes:Number = 3;wrong use of terminology
Say I have an array with 4 string elements that are 4 different urls. On the stage I have 4 movieclips that I want to have listen for a CLICK event. When the user clicks a button, the navigate to one of the 4 urls.I can loop through the buttons and add and event listener to each:
Code: private function applyPlankLinks():void { for (var i:uint = 0; i<numberOfPlankBtns; i++) {
Im tyring to turn a Movie Clip into a classic button - roll-over to display text, roll-off and text goes away, click and go to frame of animation. Each works on its own but when I put all 3 on the same Movie Clip (Tick1) each succeeding event listener seems to erase the previous one. Here is the code:
var txtField:TextField = new TextField(); Tick1.addEventListener(MouseEvent.CLICK, GoToStart); Tick1.buttonMode = true;
Is there a way to achieve what i'm trying to do here? Obviously it doesn't work this way because only the last event handler is activated and the first one is ignored.

I'm simply trying to apply the function to the two handlers in the beginning of the first line: this.txtbtn_edegem.onRelease and this.btn_edegem.onRelease
I'm making a piece of flash used for a website banner, previously i've had very little experience with action scipt as i've made various animations only having to use simple functions such as "stop()" and i've made a never ending scrolling menu also, but now i want to have an event that "onPress" a small animation is played where the mouse clicked the banner. What would be the appropriate script to link the .swf i make to the "onPress" command?
I have a wheel that the user can spin by flicking it with a mouse (think wheel of fortune). It needs to trigger an event once the spinning has finished depending on what section of the wheel it has landed on. I can get it to trigger an event but it triggers every time the wheel passes the hitTest object, not just when it is done. I've attached a sample of it.
var service:HTTPService = new HTTPService(); if (search.Location && search.Location.length > 0 && chkLocalSearch.selected) { service.url = 'http://ajax.googleapis.com/ajax/services/search/local'; service.request.q = search.Keyword;

I want to pass the search object to the result method (onServerResponse) but if I do it in a closure it gets passed by value. Is there anyway to do it by reference without searching through my array of search objects for the value returned in the result?
When does the event listener for "itemEditBegin" get added and removed? Is this essentially the same as:
<mx:DataGrid id="myDataGrid" creationComplete="myDataGrid_creationCompleteHandler(event)" /> protected function myDataGrid_creationCompleteHandler(event:FlexEvent):void {
[Code]...
Basically, I'm wondering where I should add "myDataGrid.addEventListener" if I want to do it programmatically? Should it be in the creationComplete listener function of the object itself, or perhaps in the creationComplete listener function for whatever parent object it resides in?
Code: function checkButton(buttonHit:MovieClip) { if (buttonActive == true) { buttonHit.onPress = function() {[code].........
I've built a carousel that moves a set amount with button presses, and when the movement stops the item at the front of the carousel enlarges and becomes a button. However, when the carousel is moved to the next item, the previous still stays behaves like a button. Is there any way to remove the event handler from the movieclip?
After figuring out that removeMovieClip won't work on objects with negative depth numbers, I've run into another stumbling block in some menu generation code I'm working on.For the most part, my menu code is complete, and functional. However I've been trying to clean up some of the display methods to make it a nicer and smoother interface.
When you rollover a menu item, a submenu appears. This submenu consists of a number of items. Let's pretend we have this MAIN MENU > SUBMENU > ITEM 1, ITEM2, ITEM 3.ITEM 1, ITEM2, and ITEM 3 are nested in SUBMENU. For example, the full path for ITEM 1 is _level0.mainmenu.submenu.item1.
SUBMENU itself consists of a background object and the item objects. The items all have event handlers assigned to them. onRollOver highlights a selection, onRollOut unhighlights the selection, onRelease jumps to the appropriate Movie Clip.
What I would like to do is assign an onRollOut event to SUBMENU that collapses the menu on a mouse roll out event. It works, however, when I do this, the event handlers of the nested ITEMs become nonfunctional. Is it not possible for parent and child movie clips to both have onRollOut events assigned to them? Or is there something else I'm missing?
I'm having trouble figuring out how to create onRollover handlers for movieclips loaded with loadClip. I can attach event handlers to the container clip, but not the child clips within it (the grandchildren). I'm using MX2004 / AS2.The parent clip just doesn't seem to "see" any grandchildren. It doesn't seem to be a paths issue, and I'm working in an onLoadComplete function to make sure everything's loaded first. The goal is to be able to change what happens on rollover with data pulled in (via Flash remoting) to the parent clip.
