Flash :: AS3 - Get The Name Of The Object In An Event Handler Function?
Dec 17, 2011
Below is my AS3 code:
[Code]...
If I run add('movie123'). How do I get the string 'movie123' in the enter_frame_handler function? UPDATE This forum post (Click Here) describes the issues I am having but doesn't provide the solution I am looking for. Luckily @kapep provided a simple solution that solved the issue.
The above code works most of the time but my concern is what happens if timer gets garbage collected? Is it possible that onTimerComplete will never fire because there are no other references to timer? I know timer has an internal list of handlers but that won't keep it from being GC'ed i think.
I need to return to my original function after capturing an event (downloading something) with another function. The original function needs to return a value, which depends on the downloaded data. So, I'd like to pause original function for the time needed for the download and the eventhandler function to complete it's work, and resume it afterwards.
The obvious way is to set a flag value (both the original function and the eventhandler are within the same class) and make the original function check it until the eventhandler function changes the flag. But that would be wasteful, and my AS is slow enough already:) [other parts of the application utilise some heavy graphics]. Is there another way? Like an event that gets captured "in the middle" of the function? Or some other form of flow control?
Is there a way to get the handler(s) function(s) of an event listener?
I'm trying to find a way to remove them without knowing what they are.
For example:
ActionScript Code: if (mc.hasEventListener(MouseEvent.CLICK)){ // this object has a MouseEvent.CLICK listener mc.removeEventListener(MouseEvent.CLICK, null ); }
Instead of null, I was hoping to find some function that retrieves the handler function.
I want to call the same event handler function with a click and also with a custom event. the problem is the event type that needs to be passed to the function. Is there are generic event type that can be used to call the function from both places?
Code: menuBtn.addEventListener(MouseEvent.CLICK, menuOpen ); function menuOpen(event:MouseEvent){
Ok, I have 2 buttons on the stage. Each button does almost the same thing, so I want to create a single function, and each button calls that same function (we'll name that function "Navigate")... however, the function will need to end up doing something different dependant on which button was clicked.So, previously, in AS2, I would've added some code onto the buttons themselves with on(release) methods, like so:
Code: // Define the Navigate function function Navigate(myLabel){
Trying to migrate my way of thinking from AS2 to CS4/AS3. Ok, I have 2 buttons on the stage. Each button does almost the same thing, so I want to create a single function, and each button calls that same function (we'll name that function "Navigate")... however, the function will need to end up doing something different dependant on which button was clicked. So, previously, in AS2, I would've added some code onto the buttons themselves with on(release) methods (see CODE EXAMPLE 1) So, each button effectively calls the Navigate function, and passes a different frame label to the function. Now, I'm trying to recreate this functionality in AS3. As you all know, on(release) has been done away with (still don't know why), but we now have to use event handlers, so I'm trying to figure out a way to pass a different frame label argument to the Navigate function. Currently I can achieve that by using a switch statement to test which button was clicked, and act accordingly (see CODE EXAMPLE 2).
I created an array with movie clips now how can i target one movie clip with event handler function . so that when i clicked on one movie clip a message should be displayed
I have an action listener :myText.addEventListener(TextEvent.LINK,linkClickHandler); As according to this, i need to write an event handler function seperate to handle the text link event.Now my requirement is i need to write that function in the same line isntead of giving its name.ie, something like mytext.addEventListenet(TextEvent.LINK, function(event: TextEvent) {....code comes here....});
can i do like this in AS3.What will the syntax for this if possible.Also i want to know, wether i can pass one more extra param to the event handler other than event which is the default parameter.
I have a Tree, which has an itemRenderer. On the itemRenderer, driven by the XML conditions, objects are created dynamically and added as a children to nodes. These new objects shall trigger an event handler ( some click events mostly ). How do I pass the event handler to the tree and later to the dynamically created new objects inside itemRendere?
I have an event listener for a custom event type. This custom event overrides the clone method as required.In this event listener I want to dispatch an instance of a different type of event... a different custom event instance altogether. It also overrides the clone method as required.The problem is I'm getting a type coercion error: TypeError: Error #1034: Type Coercion failed: ...I do not know what is trying to do the casting. My code is:
/* elsewhere in a method */ addEventListener(GestureEvent.GESTURE_SCALE, handlePinched); /* the event handler */
I seem to be having a recurring problem attaching events to a button i have created within 2 other movieclips.I get the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
So it looks like it can't find the button, in order to attach the event listener. The question is why? I am attaching a similar event to a button on the main timeline and that works fine. So it looks like a scope issue, but I am referring to it properly.
I have written a framework that facilitates RPC calls between AS3 and PHP 5 called FlashMOG. I recently got a forum request that has introduced a pretty bizarre question regarding access control. This will be a lot easier to discuss if you have access to the FlashMOG 0.3.1 client source which is here:
[code]...
The basic idea is that I have a FlashMOGService class which has an RPCSocket member that it may share with other FlashMOGService objects. The idea is that you can create two distinct FlashMOGService objects and have them both connect to the same host/port via socket. I use my special RPCSocket class for two reasons:
1) Let developers use one port but separate functionality into two distinct services...a form of multiplexing i guess
2) RPCSocket adds functionality to the standard Socket class that works to serialize and unserialize data and get it where it needs to go. The essence of the problem here is that created a class with a FlashMOGService object as a member and has tried to assign a private method of his class as an event handler to the FlashMOGService object:
[Code]....
My initial thought is that this should be fine because it's all done within the class. However, when I consider the monkey chain that results in this function being called, it seems almost logical that it wouldn't work. The problem is that the browser freezes when a socket message arrives that tries to call the service's client method, _service.client.firstClientMethod. This client firstClientMethod is attempted when data arrives from the server on the Socket (an RPCSocket, actually). The RPCSocket class deserializes the socket data and extracts an array with a service name, a method name, and an array of arguments. It looks into its own private class variable (an array of services using the RPCSocket) and tries to invoke whatever function was assigned thusly:
[Code]....
I'm guessing there's some kind of infinite loop going on to check access control for the various intertwined classes.
I'm trying to find a way that I can control how a flash movie handles the click event from the HTML page outside the movie.
I run a website where we have advertising space for Flash Ads provided by our customers which, when clicked, open their own website in a new browser window (i.e. target='_blank') - however this causes us a few issues:
1.) We want to track the success of their ads, so we give them a custom URL that their ad should link to instead of linking directly to their site. This URL logs the click before redirecting the browser to the customer's website.
2.) Often the flash files we get use GetUrl() which seams to trigger the popup blockers in IE 7 & 8.
These two points mean we have to provide them with the custom URL for them to include in their flash ad, and/or tell them how to set up the movie to handle the clicks in a way that doesn't trigger the IE popup blocker, and this doesn't make it as seamless as it should be to place an ad on our site.
So, what I'm trying to do is find a way that I can reference the Flash movie object with JavaScript (or similar), and set the click event to open up a specified URL - so if the customer's flash movie doesn't have the right URL set in it, or is triggering IE's popup blocker it doesn't matter because when we display it, we can modify the event handler to use the correct URL and to open up their website without tripping any popup blockers.
I am having an issue with a class I'm working on. I currently load an image as a bitmap and store its data into regState:BitmapData so that I may make new instances of that image later on. When I test if I can use the loaded data at a later time with my newBitmapIntance() function, it says that regState is null. I'm lost as to why this is the case, since it works flawlessly to create an instance of itself in my loadContent() function.
Class so far For reference: package { import flash.display.MovieClip;
Alright, I've looked online at a bunch of different collision tutorials but they don't explain what I'm looking for. I want object A to hit object B and then execute a function via to a Event listener.
Any thoughts on a good way to accomplish something along the lines of
var request:URLRequest = new URLRequest("http://myurl.com"); var loader:URLLoader = new URLLoader(); loader.addEventListener(Event.COMPLETE, function(event:Event):void { System.setClipboard(loader.data); });
It seems as if System.setClipboard() isn't available inside an event handler (which makes at least some sense given what I know about Flash security).get it to work? or block on the URL load so that I can then call setClipboard() in the main event flow?
I am writing a program that needs to go to a random frame after clicking a button. However, the program also needs to start on a random frame. When I call the function at the start of the program it gives me an 1120: Access of undefined property event error. The function is originally written as followed:
function randomMatchedTrial(event:MouseEvent) { ... lots of code that probably doesnt matter, but let me know if it does... }
the program starts by calling the function as followed:
randomMatchedTrial(event)
Can event handler functions be called outside of the event listeners they are handling?
I have what seems to be a simple task, yet I cannot seem to figure it out. I am busy creating a project in ActionScript 3, and while I am fairly fluent in ActionScript 2, I am being stumped a bit here.
I have a simple dynamic text field inside a button object. This text field has the name of txt_title. I have attached event handlers to change the alpha of the buttons when they are hovered over, however I also want to change the value of the text field within the button, when hovered over. My event listener looks like follows:
Is it possible to grab an event, hold it in a class property, do some action, then, when that action is complete, dispatch an event and then retrieve the original event.target in the listener?I am trying to avoid using a custom event for now, as it is giving me massive amounts of heartburn when dispatching it from a loaded SWF.Here is some code (that doesn't work)what I am attempting to do:
I am able to stash the event in a class variable, and then access it later, but the cherry on the icing would be to get it from the event fired withing tweenHandler() in my example above.
Edit: Well,it doesn't look possible.I am currently storing the retrieved event in a property _event and then getting it at a later time when I need it.This seems to work, but isn't wonderful.
I'm trying to add a custom callback handler to a NetStream client in a p2p application. The problem is, when I add such a handler, the NetStream Client doesn't function as it did before. It seems the NetStream.client object is changed. I know the default object is this. But changing the client to this doesn't solve the problem.The remoteControlStream, is the incoming stream. And the localControl stream is the stream being publishedThis is the localControlStream that's being send by the peer, and received as remoteControlStream:
private function initLocalControlStream():void{ localControlStream = new NetStream(nc, NetStream.DIRECT_CONNECTIONS); localControlStream.addEventListener(NetStatusEvent.NET_STATUS, localControlHandler); localControlStream.publish(myPeerID+"control");[code]...
The onPeerConnect method of the localControlStream doesn't get called when I connect when the above handler is added. When I remove the that handler, the onPeerConnect method gets called.
How would I make an image I load using AS3's loader class into a button with an event handler on it? Below is what I have started. And below that is my error I get when I click the message.
AS:
//call function that starts loading my image callButtons(); function callButtons():void {

the error I am getting when I click the spanish.png on the stage is: ArgumentError: Error #1063: Argument count mismatch on MyVideoPlayer_CS4_fla::MainTimeline/playSpanish(). Expected 0, got 1.I NEEDED TO ADDED evt:MouseEvent
is it possible to determining what object calls a function based on an event listener? for example, i have 2 buttons on stage that call the same function when they are clicked. i'd like the function to determine which button was the sender.
I'm adding event handlers to dynamically created movies. The event handler is not active and the cursor does not change to a finger over the clip Here is the applicable code.
Code: function loadSubNav():void{ //Load Thumbnails
