Actionscript 3 :: Loops And Event Listeners?

Apr 13, 2010

I have an array that returns multidimensional data from an mysql database, when this is collected the createNews function creates the user interface. The problem I am having is the loop is iterating quicker than the UI is being created, is there a way to use event listeners with loops so it only continues after my function has completed its work?

ActionScript 3.0 :: Event Listeners Added In Loops?

Aug 5, 2009

I'm trying to set up a simple button navigation system with a for loop that pulls a mc out of the library "i" number of times, adds it to the stage, then adds an event listener to it with a unique function name -- something like "onClick1, onClick2, etc", but with onClick[i] somehow in the loop instead.

var btnArray:Array = new Array();
for (var i:uint = 0; i<6; i++){  var myBtn:btn = new btn();  btnArray.push(myBtn);  addChild(btnArray[i]); btnArray[i].x = i*50+50;

Actionscript 3.0 :: Buttons Event Listeners And For Loops

Jun 20, 2010

I want to say that everything I code and work with is created through a main class and added to the stage through actionscript, the stage is completely empty before running.I've got a button in my library, and I create 8 of them and add them to the stage. I also add them to an aaray which i then compare in a for loop to add an event listener to them. I do it this way because they all run the same function. Each of the 8 buttons has a variable which is unique to that specific instance which I will use to do execute different sections of the function that gets called when I click one of the buttons.[code]

ActionScript 3.0 :: Button MovieClips Loops - MouseOut Event Listeners

Apr 20, 2009

I have a button that is a movie clip that is set up with animations triggered with MOUSE_OVER and MOUSE_OUT event listeners. The glitch is that once the mouse is over the button ... each ensuing pixel that the mouse is moved, loops the animation again. That probably didn't make a whole lot of sense, so I posted the file on my test site [URL]. You have to drag your mouse slowly across the button to see this. The bottom part of the button works as I'd expect. When you roll over the text at the bottom of the button, everything functions as it should. The looping problem starts when you roll over the image portion of the button. For some reason it considers each consecutive pixel rolled over to be a new event and consequently triggers the "over" animation again.

The code I have is below. I've commented out the MOUSE_OUT function for now. There is also a screenshot at the above link of my Layers palette for the button clip in question. I put a "stop" label at each frame that has an action so you see the actions used.
oneBedButton_mc.buttonMode = true;
oneBedButton_mc.addEventListener(MouseEvent.MOUSE_OVER, overEffect);
//oneBedButton_mc.addEventListener(MouseEvent.MOUSE_OUT, outEffect);
function overEffect (e:MouseEvent) {
oneBedButton_mc.gotoAndPlay("over");}
function outEffect (e:MouseEvent) {
oneBedButton_mc.gotoAndPlay("out");}

ActionScript 3.0 :: Adding Event Listeners To MovieClips - Arrays And For Loops

Jan 31, 2010

I'd like to add event listeners to movieclips (already on the stage), whose names are called from an array one by one, into a for loop.

Code:
// there are 4 movielcips on the stage with name a1 - a4.
// create array
var Bro:Array = ["a1","a2","a3","a4"];
// for loop
for ( var i:Number = 0; i < 4; i++) {
// Add event listener to array values to buttons.
Bro[i].addEventListener(MouseEvent.ROLL_OVER, roll, false, 0, true);
//execute this function on rollover
function roll() {

ActionScript 3.0 :: Can Event Listeners Only Be Added To The Class Which Dispatched The Event

Sep 3, 2009

Can event listeners only be added to the class which dispatched the event? I ask because I want to have the logic for the listener on the main class, and the action is dispatched on click from a thumb which is instantiated in a scroller class. Kinda like this:

ActionScript Code:
pseudo code:
class main {
main() {

[code]....

This doesn't work. Why can't the main class listen for an event on the thumb class?

ActionScript 3.0 :: Add Event Listeners Between Classes?

Mar 11, 2009

So I've gotten into using my own as Classes, and have an interesting question.
My main swf calls a php script that gets data from a mysql database which is returned as XML. Part of that data that is retrieved is a filepath to a jpg image. It then takes that filepath and other information, and passes it to my external class, the "news story" class.

All fine and good. Then, the "news story" class uses a loader to load that image along with some text, organize it, and voila, you've got your own very pretty "news story". (I'm extending the MovieClip class here, though I suppose it doesnt matter)

Now, my main swf uses this component to load multiple of these "news stories". The problem is, theres that load time for the image. The main swf is loading them all one at a time, because they are putting each one together on their own.

The key here is that it be dynamic. So, since we don't know how much text is in each "news story", we also therefore don't know it's height. What I'm doing is creating each story in the main swf, pushing it into a "news story" array, adding an event listener to each ones' loader, and when the event listener is triggered, I want it to go to the 'add content' function where it sets the news story's Y value based off the position and height of the previous story that was added (stacking them, obviously). This makes sense, because otherwise it'd add them all on top of each other and it'd be a jumbled mess.

The problem is, the event listener is on the loader object INSIDE the component actionscript. So, how do I figure out which news story to set the Y value for? Because the eventlistener is listening to the loader, not the class. I hope this makes sense AT ALL. Here is the code:

Quote:

while (fancy shmantzy conditions)
{
/*creates the news story and passes xml data to it (filepath, etc)*/
storyBlock = new StoryBlock(a bunch of parameters);
subCBArray.push(storyBlock); //array that stores each news story info

In AS2 you could add an onRelease to multiple buttons like this:

onebutton.onRelease = anotherbutton.onRelease = lastbutton.onRelease = function() {
//do something when either button is pressed;
}

Is there something similar possible in AS3 using addeventlistener? Besided copying the same addeventlistner line for all individual buttons?

ActionScript 3.0 :: References And Event Listeners?

May 17, 2010

Lately I've been twitching in the back of my head wondering just how many references to objects that I'm making, and whether or not they are getting GC'd or not.My question in this sense refers to event listeners and whether or not they are removed in certain cases where you get rid of an object. Two examples:

First, and I think this one is an easy one... when you create an object that adds an event listener to itself INSIDE it's own methods (e.g. this.addEventListener(e:Event, function)), when you REMOVE that object (this), do it's event listeners disappear too? I can only say yes, because they are referencing THAT object and are INSIDE that object.

So I think that question answers itself (but I'd love to know if the truth says otherwise).

But secondly, if you add an event listener to an object from a sibling or parent object, and then remove the object, does that event listener stick around, therefore maintaining a reference to that object and keeping it in memory? And is that the concept that people keep referring to of 'weak' event listeners? E.g. someChildObject.addEventListener(e:Event, function)Also, are event listeners by default strong or weak?

And I am assuming that 'yes', it DOES keep the reference. Which, if you are a n00b programmer like me, you probably are all like, 'aww sh*t damn, how am I supposed to make sure that my objects are getting thrown in the garbage collector's mouth of goodness every once in a while?

ActionScript 3.0 :: Using Multiple Event Listeners

Jul 1, 2009

I have a movielcip (A) class in which I have used a Tween class effect on a child movieclip (B) scrollRect. The (B) Movieclip in turn has several movieclips whose have tween class effect being executed on thier child movieclips.the tweens are all unique to each movieclip and the event listeners are taken off once completed.This works all well and good in FLASH IDE..My problem arises when I try to view this in a browser on a Windows XP.[code]

What is happening in most cases it that the animation appears to "stick" but i think what may be happening is the listening or removal of the event listeners. The animations are left incompleted.Is there any rule of thumb when using multiple event listeners?[code]the effect disables and re-enables the buttons when its done.... then the listeners are removed.each one with the exception cretes its own unique tween (obviously this is a custom class built as each clip)

Flash :: Why Are Event Listeners Firing More Than Once

Jun 14, 2010

In my Flash project I have a movieclip that has 2 keyframes. Both frames contain 1 movieclip each.

frame 1 - Landing
frame 2 - Game

The flow of the application is simple:

User arrives on landing page (frame 1) User clicks "start game" button User is brought to the game page (frame 2) When the game is over, the user can press a "play again" button which brings them back to step 1

Both Landing and Game movieclips are linked to separate classes that define event listeners. The problem is that when I end up back at step 1 after playing the game, the Game event listeners fire twice for their respective event. And if I go through the process a third time, the event listeners fire three times for every event. This keeps happening, so if I loop through the application flow 7 times, the event listeners fire seven times. I don't understand why this is happening because on frame 1, the Game movieclip (and I would assume its related class instance) does not exist - but I'm clearly missing something here.

I've run into this problem in other projects too, and tried fixing it by first checking if the event listeners existed and only defining them if they didn't, but I ended up with unexpected results that didn't really solve the problem.

AS3 :: Flash - Removing The Event Listeners?

Dec 17, 2010

I have a basic question about manually removing event listeners in actionscript 3.If I have a function like:

private function doStuff(event : Event):void
{
//let them save
var f:FileReference = new FileReference();

[code]...

How do I remove the event listeners when the saveDone function is called? Normally I just change the "add" to "remove" like:

f.removeEventListener(Event.COMPLETE,saveDone);

However, f is a local variable, and I can't get to it after the doStuff function ends.

private function saveDone(ev:Event){
f.removeEventListener(Event.COMPLETE,saveDone);

Actionscript 3 :: When To Remove Event Listeners

Jan 23, 2011

How do you know when you should remove event listeners? For example, I know that if I have a TimerEvent listener, I can safely remove that event when I have stopped and / or deleted my timer. Or, if I have a display object on the stage, and I remove it, I can safely remove any event listeners associated with the display object.

ActionScript 3.0 :: Event Listeners And Overlapping MC's?

Feb 1, 2009

Im sure this has been asked a million times, so forgive me but I cannot seem to find an answer or my search query is wrong. I am using Tweener for animation.

I have 2 MC's on my stage. I have an event listener for my main MC (MOUSE_OVER, MOUSE_OUT) that triggers Tweener to animate another MC on top of the main clip. The problem is that when it overlaps the listener no longer works, and tried to execute the MOUSE_OUT. I understand why its not working, I just cant find a solution. Here is the code and a simple FLA.

ActionScript Code: import caurina.transitions.Tweener;
square.addEventListener(MouseEvent.MOUSE_OVER, RollItIn, false, 0, true);
square.addEventListener(MouseEvent.MOUSE_OUT, RollItOut, false, 0, true);
function RollItIn(evt:MouseEvent):void {

ActionScript 3.0 :: Event Listeners Only On MovieClip

var nome:String = e.target.name;
TweenMax.to(curs,1 ,{y:contMain.getChildByName(nome).y + 23});
}

This code moves a cursor calculating the y coordinate depending the moviclip that is mouse overed. Now the movieclips have some textfields so when i mouseover the movieclips all works ok but when i mouseover the textfield i receive a #1009 error.
