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++) {

I have this code:
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, in ActionScript, an event is dispatched:
foo.addEventListener("some event", someHandler);
foo.dispatchEvent(new Event("some event"));
At what point are the event handlers executed?
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?
Simple example:
_movieClipClassVariable = new MyCustomSpriteSubclass();
_movieClipClassVariable.addEventListener(MouseEvent.CLICK, function(event:Event):void {
trace(this); //gives 'global'
});
What about memory usage and garbage collection objects with anonymous handlers? Is declaring handlers as class method better?

View 4 Replies I have a movie clip that contains several movie clips, only one of which should be shown at a time. Which one is shown, depends on what buttons the user selects.Having trouble with the syntax for passing the argument in a button to the function that controls the tweening of the clips. (When I hard code the references into the function, it works, so I know the basic function is ok).There's a clip called 'slide1_mc' which contains various MC's to be shown based on user selection (in this case, using 'system' clip as the first one already showing). Here's the code in the parent clip of that item:
Code:
var currSection = slide1_mc.system_mc;
function changeSection(newSection):Void {
TweenLite.to(currSection,.3,{_yscale:200, _xscale:200, _alpha:0});
[code]....
Here's one of serveral buttons that will control the content to be seen:
The code in the button is:
Code:
var changer = slide1_mc.software_mc;
smallButton.onPress = function() {
_parent.changeSection(changer);
};
So - the initial part of my function works so I know my 'external' initializing of "currSection" is working (that clip is zooming/fading out)... but then the clip that I want to fade in isn't doing anything.

i have a music jukebox, with ten buttons. in the first keyframe, of the main timeline, a put a function that will be used for every button to load the mp3 to play. The problem, is that when i pass the arguments on each button to call the function, the "filme" and "som" arguments are lost.
here is the function:
function carregaSom(filme, som, url, msg1, msg2, tempoComeco){
_root.createEmptyMovieClip(filme, 1)

Is it possible to pass arguments "by reference" instead of "by value". I know it's possible in almost every programming/scripting language I came across until today, but I didn't find any hint for doing it in Actionscript For those who don't know what "by reference" means: If you want to pass a Number to a function, say
Code:
var mynumber:Number = 5;
calculate(mynumber);
and you change the value of the argument inside the function, e.g.
[code]....
then the call to calculate normally does NOT change the value of mynumber because you have passed mynumber "by value", which means the value of mynumber has been copied to the num argument. This means mynumber is 5 all the time.Now sometimes u want to be changing arguments given to a function inside the function, and this is where u will normally use references. Passing mynumber "by reference" would mean that after calling calculate the value of mynumber will be 6...I know complex Objects like MovieClips are passed by reference. But how to do it with simple DataTypes like Number, Boolean etc.?

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)

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:
addEventListener(Event.ENTER_FRAME, function() : void {
controls.elapsed = stream.time;
});
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.

'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.

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;

What would be the appropriate script to link the .swf i make to the "onPress" command?
View 5 RepliesYou can do this:
PHP Code:
public function (args ...)
To take in any number of arguments. Is it possible to then give the content of that args array to a new function:
PHP Code:
public function bla (args ...){
pleh( changeArrayIntoArgs(args) );
}
So that that would be the same as just passing arguments manually. lets say bla got 3 arguments:
PHP Code:
bla(v,vv,vvv);
So that bla then executes:
PHP Code:
pleh(v,vv,vvv);
I've drawn a pretty button in Flash and given it the Class name PausePlayButton. It extends PlayerController, which allows it to toggle on and off and control whether a MovieClip is playing or not.When I instantiate it, I want to pass a reference to the MovieClip it controls into the contructor so that PlayerController has access to the MovieClip's public methods. However, I can't pass a reference into the constructor of PlayerController, unless I can pass it into the constructor of the symbol itself and call super. But where is that constructor? How do I give the button a reference to another object?
