Actionscript :: Switching Back Into Previous Function From Event Handler Function?
May 13, 2010
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?

I have a function with some if and else...if statements in a particular frame. In this assessment program, the user goes to other frames, then evaluates several variables at the end. If the user gets more than 3 wrong, the user goes back to the scenarios that were missed (i.e., a particular frame label). When I have tested this program, I can get back to the right frame/scenario, but a particular button's function won't work. Is there something where I need to "reset" this function the second time the user goes through it because it remembers what was done the first time?

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.

Does anyone know if there is a way to get the name of the function that my code is running inside?
Code:
_btn.onPress = function () {
trace(something);
}
this would then output "onPress" or something like it...

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'm trying to get a quick replay command, "pressing space returns the scene to the previous frame".
[Code]...
The current function returns me to a previous frame (40), however the event does not stop, rather it keeps on adding new events ontop of each other once it returns to main frame. The main frame being where the actionscript is executed.

I'm trying to make a CustomLoader class that extends another class.In the contructor of my CustomLoader, i need to call super(myLoader:Loader) where myLoader is a Loader object. Problem is I need to listen to the complete event of the loader before passing it or i'll get an "Error #1009: Cannot access a property or method of a null object reference". but if i put super() in a handler function i get an "Error 1007: A super statement can be used only inside class instance constructors."
Here's part of my code:

public class CustomLoader extends ParentClass

I'm trying to start a function from within a click handler that is being triggered when I load some XML, just like this:
Code:
function LoadSomeXML(e:Event):void {
thumbContainer_mc.addEventListener(MouseEvent.CLICK, thumbClick);
} function thumbClick(event:MouseEvent):void {
startImgSlider();
} function startImgSlider():void {
trace("ok, now you reached 'startImgSlider()' function !!!");
}
The problem is that I cannot reach the startImgSlider() function with the code above. How to do it right. Has something to do with the scopes?

I am having problems with a ChangeWatcher.Everything seems to be set up correctly.The canWatch method returns true, the isWatching method returns true and if I query the return value of the getValue method I get the correct information, including changes. But for some reason the handler function just doesn't fire.

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.

I've created a button (type: MyButton) with two child, a text (TextField) and a image icon (type: MyIcon). Then I've append an eventlistener mouse_click on my button. As soon as I click on the text, the e.target on the handeler function is recognized of MyButton type. Otherwise, if I click on the image icon (child of button) the e.target is MyIcon type, instead of MyButton. How can I prevent this? I need all click to be recorded on the button, where I've stored some attributes I need on handler function.

whenever I try to call the removeMovieClip function in a callback handler, it just doesn't work! Maybe I'm tired, or I've just missed something this is apparantly obvious. In my code exert below, is just a simple script that attaches a movie clip to stage (square_mc) and creates a duplicate instance. When the component button is clicked, I want the original movie clip to be deleted, but nothing happens!
Code:
this.attachMovie("square", "square_mc", this.getNextHighestDepth());
square_mc.duplicateMovieClip("square_mc2", this.getNextHighestDepth(),
{_x:50}) var listener:Object = new Object;[code].............
