Flash :: Actionscript On Change Handlers

Feb 3, 2010

I have a text box (dynamic) whose value is being changed by javascript using the setVariable method. Bascially I'm now stuck in getting the flash application to recognise when the text box value has been changed, onKeyUp etc.. do not seem to work. The below code works if the user types in to the box, but if it is changed via JS it does not pick up the change, therfore not populating my variables. What Listener should i be using?

Flash :: Best Way To Handle EventListeners/Handlers For 1000 Buttons?

Aug 18, 2011

I'm working on a game where users can win buttons/badges as awards. I estimate there will be around 500 awards, in all.I want to allow the users to sell their duplicate/unwanted badges to the bank and buy new ones from the bank.I am showing the badges in multiple awards frames. Below the badges, I show the count, along with a "Buy" and "Sell" button.My question is: What's the best way to handle SO MANY buy & sell buttons? Is there a way around coding 1000 eventListeners and 1000 eventHandlers?

One possible solution is to name my buttons, incrementally, like "buy_mc1", "buy_mc2", etc. Then do a loop to create listeners for this["buy_mc" + i]. However, I would then have to make VERY sure that I link these back correctly to the awards.Currently, I have an "award_mc" field in my database, which stores the name of the movieclip in my .fla. From that, I can access related assets, like the count field, like: this[db.award_mc + "_count"].txt.Unfortunately, this method does not lend itself well to looped access.Maybe I can create an array of movieclip names that are in synch with the buy/sell buttons. For example:

myArray = {aMissionAward, anotherAward, ubernessAward};

My buttons would be: buy_0, buy_1, buy_2, etc.

When someone clicks a button, I can link buy_2 to "ubernessAward", then look for "ubernessAward" on the database.How can I get the number from the button, though? Even if I can loop through setting up the eventListeners, will I have to set up individuatl eventHandlers to process the correct index number? I was not able to get this to work with buttons on the stage. Apparently, buttons are a static class. MovieClips are dynamic, so I was able to get this to work by using MovieClips. Here's what I did:

Added 3 MovieClips to the stage.
Named them "mc0", "mc1", and "mc2".

Add this AS3 code:

for (var i:Number=0; i<3; i++)
{
this["mc" + i].addEventListener( MouseEvent.CLICK, onMcClick );[code]....

From here, I can tie the awardKey to an array of MovieClip names. Then, I can use the MovieClip names to read my database.This is why I come to Stack Overflow, FIRST, when I have a problem. :)

Flash :: Flex - Setting Up Dynamic Images And Event Handlers For Each In Builder

Aug 26, 2010

How can I add a set of dynamic images and then add event handlers to each that trigger a different event? My scenario is that I have a remote service that grabs a set of data (ArrayCollection) that has a className, classID and classDescription. I would like the images to have event handlers that trigger a new panel display that would show the "classDescription" for the particular class that is clicked. My problem is figuring out how to retrieve the proper set of data and adding the images properly to the panel.

ActionScript 3.0 :: Firefox - Turn Off The Mouse Event Handlers In Flash Applications

Feb 17, 2010

I'm now convinced there is some sort of mechanism built into Firefox that seems to turn off the mouse event handlers in flash applications on the html page when the user scrolls the page or does any other sort of mouse interaction with the web page itself. This issue does not arise in IE (go figure that one) or chrome, but does seem to arise in Safari as well. I'm sure theres probably something I need to do to the html to make sure the flash mouse events are always active and superseding whatever mouse events are built into the browser. At first I thought it might be because the one nav bar i did was rather complicated with lots of layers and AS on multiple frames, but when I did a much more simple navbar with only 1 frame of AS, i still run into the same issue.

ActionScript 2.0 :: Using The OnKeyUp Handlers?

Feb 17, 2009

I've been using this site for a while and this is my first post. Recently, I've had some trouble using the onKeyUp handlers. It's really strange and I'm not sure whether it's a bug in the way I've lay out my code or the player itself.

But, whenever I used getAscii() or getCode() methods of using the keys to basically make stuff move, the first second of movement is really jittery. It'll move, pause still, then move properly. I don't get why though, it's the same code I've used in the same layoutof (Key.isDown(Key.etc...)) codes and those worked fine.

ActionScript :: When Are Event Handlers Executed

Jun 23, 2009

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".

Actionscript 3 :: What Is 'this' In Anonymous Event Handlers

Jul 3, 2010

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?

ActionScript 3.0 :: Pass Parameters To Event Handlers?

Jul 23, 2011

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)

Flex :: Unit Testing Event Handlers

Jul 24, 2009

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?

ActionScript 3 :: Using Anonymous Functions As Event Handlers?

Dec 12, 2010

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?

Actionscript 3 :: Deal With Same Method Body In Different Handlers?

Aug 23, 2011

I have a method fired on mouse down:

private function setGender(e:MouseEvent):void
{
check.visible = true;[code]...

The same method body is shared by another method fired on a keyboard Event (so, it takes a keyboard Event for argument). Which is the best way to deal with situations like this one? I would like to have only one method.One way could be to create a new method called by the two event handlers (even if, if I need to use e.target, it can change according to the type of event and other variables, so I should eventually create a method that takes e.target as a parameter). This creates three methods...Would it be possible to change for example e:MouseEvent with a parent of MouseEvent and KeyboardEvent?

Actionscript 3.0 :: Event Handlers Counter Acting Each Other?

Mar 19, 2011

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.

Code: Select allHome.lnk1.addEventListener(MouseEvent.CLICK, clickHandler, false, 0, true);
function clickHandler(e:MouseEvent):void {

ActionScript 2.0 :: Event Handlers For Dynamically Created Mc's?

Sep 27, 2005

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.

protected function myDataGrid_creationCompleteHandler(event:FlexEvent):void

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?
