I have just added a menu screen to my game and I get the following error:
ActionScript Code:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

I have this in my constructor:

The problem is I get Error: Error #2094: Event dispatch recursion overflow. Why does removechild keep getting called if this.parent does not exist? Why doesn't removing event listeners work?
I found this code for a contact form at[url]...and it dynamically creates input fields and buttons. I didn't like the dynamically drawn submit and reset buttons, so I added my own MCs(my 'buttons') to the stage.I tried modifying the code and took out the dynamically drawn buttons..However, I cant figure out how to add Event Listeners to the buttons which exist on the stage--Im getting undefined errors...[code]...
View 2 RepliesAs part of a very large project, I want the ability to set stage level event Listeners.
This works very easily with MouseEvent s but I can not seem to get it to run properly with KeyboardEvents. Having google'd this issue I have found very little on the subject. Mostly noobish type questions of syntax and so forth, but I have seen comment of people claiming to have it work for them.
To ensure no issues with any other code, I have made a blank project and blank .as file, with only the event listener code:
[Code]....
Click events are always captured and traced correctly, without fail. Pressing keys appears to do nothing. If however you mash the keyboards very very quickly, one or two key events will trigger sporadically.
I think I have been generating duplicate Event Listeners behind the scenes which is causing me some problems.
I like to find out what Listeners are in existence at a single moment. My code is long so it is hard to go line by line to isolate the issue. It would be faster if I knew what Listeners are were activated.
I create a stage keyboard event listener in an externally loaded swf such as:
Code:
stage.addEventListener(KeyboardEvent.KEY_DOWN, onDown);
My question is how and where I should remove this event listener? I have added an unload event handler to the external swf like this:
Code:
this.loaderInfo.addEventListener(Event.UNLOAD, unloadHandler);
The unloadHandler code looks like this:
Code:
private function unloadHandler(event:Event):void {
stage.removeEventListener(KeyboardEvent.KEY_DOWN, onDown);
}
When the container swf unloads the external swf, unloadHandler() gets called, but with the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
Where should the keyboard event be removed?
i am making a simple game i want to be able to add an keyboard event lisnter within the class constructor. However i am having trouble. i undertsand you have to pass the stage through a listed display object property stage? anyway i am getting errors that do not recognise my event listener keyboard event.

I'm adding and removing stage event listeners I am relatively new to AS 3 and have been building a liquid layout site unfortunately I do not have a strong grasp of classes and have been doing all of my scripting on the main timeline with encapsulated script within MC's.
basically I am calling on the same functions over and over and those are mostly resize functions which I have added StageEventListeners on the appropriate frames to listen for resize events on that stage now as of now I have literally dozens of these scattered about the site. when testing my site things are running fairly smoothly however I keep getting error messages in my output window that go a little something like this.

I have 22 buttons (each named buttoni where i is a number between 0-21...e.g. button0, button1, button2) that I've created and artfully arranged on the stage in my .fla file. The document class for the .fla file is People.as, and in People I'd like to give each button a rollover and click event listener, but I can't figure out how to refer to them using a loop.
Here's my code, which obviously doesn't work:
ActionScript Code:
private function initButtons() : void {
for (var i:int = 0; i<numSquares; i++) {
var thisButton : String = "button" + i;

I found this code for a contact form at msinghinteractive easy-to-use-flash-as3-contact-us-form-class and it dynamically creates input fields and buttons. I didnt like the dynamically drawn submit and reset buttons, so I added my own MCs(my 'buttons') to the stage. I tried modifying the code and took out the dynamically drawn buttons..However, I cant figure out how to add Event Listeners to the buttons which exist on the stage--Im getting undefined errors...The fla is directly associated to a main.as class which just determines the parameters of the .as class it is tied to -to set the size of the Contact form.This is the entire class:
Code:
package{
import classes.*;
import flash.display.*;
[code]....
where btn is the instance name of my submit button MC.My problem is that because my buttons exist on the stage I dont know how to add Event listeners within that class---or rather doing that doesnt work because the listeners are throwing that undefined property errors--I gave them instance names...
I am creating a site with lots of big scrollable text-boxes in it. Each text-box object contained some text, and two buttons to scroll up/down with. The scroll buttons each had an event listener so the text moved when you clicked them.
These text-boxes were stacked on-top of each other with all except one having an alpha of 0. If I wanted to change which text-box is active I move it to the front and call a small TweenLite animation.
To the left (outside of the text-box objects) I have an object similar to a menu. It also has about 12 or so event-listeners (one for every button).
This turns out cause A LOT of lag an it's very troublesome for my laptop to run it. reduce the number of event-listeners on the stage and also the amount of text-boxes.
What I was thinking was to add the text-boxes using AS so I only have 1 on the stage at a time but I couldn't figure out how to do it. I also thought it might be better to just use 1 big event-listeners and from mouseX and mouseY decide which button the user is trying to push.
I have a movieClip on stage, inside is a dynamic textfield, and I have set mc.scaleY = 0;
Code:
mc.scaleY = 0;
mc.buttonMode = true;
mc.mouseChildren = false;
And suddenly everything above and below (on the whole stage) where the movieClip actually is receives mouse, I can see by the button mode. But it only happens with dynamic text, not static.
I have attached the example:
I have a loop which creates a bunch of movieclips and sets them on the stage.As I create each one I attatch an eventListener to it.My problem is that when the eventListener fires, the function it calls always works on the first mc added to the stage, not the one that fired the listener.How do I fix this?Here's a bit of the code:
Code: Select allfor (var i:int=0;i<numOfItems;i++) {
item = new Item();
//etc etc[code].....
In AS3 on Android is it bad from a performance perspective to attach mouse event listeners to individual sprites rather than to the stage? I am writing an app for an Android phone using AS3 in Flash Builder. The app has multiple screens that respond to user touch. The screens are arranged in a hierarchy and show list data so that when you click on an item in a list you are presented with a new screen with a new sub list on it.
I have been using an event listener to detect mouse / touch input and based on something I read that indicated that performance is much better if you keep the number of objects you are listening to to a minimum I have attached the mouse listeners from each screen to the stage object.
This all works fine but I am finding that as I move between screens (and they get popped or pushed onto the dislay stack) I have to keep track of alot of adding and removing listeners to the stage object. If I don't then windows higher up the hierarchy than the current screen keep receiving mouse events.
If I used listeners attached to sprites in each window then when the window was removed from the display even though it is kept in memory (ready to be popped back when a child window is closed) it won't receive any mouse events....
Performance doesn't seem to be impacted using listeners directly on sprites when using my HTC phone to test with, however I obviously don't know what it will be like on other phones. Does anyone have any experience either way or a view on the best approach?
I want to make a static function that I can use in all the custom classes.It should be some kill(); function that would remove the object from the stage as well as removing its event listeners. I made it in Document class, and it didn't work. Here's the code:
ActionScript Code:
public static function kill(e:DisplayObject)

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?
An odd thing is happening for me, my eventlisteners only fire off once then they seem to stop working.
This thing is a movieclip that slides up the parent movieclip and another movieclip within mc slides it down. They only work once.
ActionScript Code:
slider.up.addEventListener(MouseEvent.MOUSE_UP, activateSlider);
slider.down.addEventListener(MouseEvent.MOUSE_DOWN, activateSlider2);
var frameBoolean:Boolean = false;

Environment: I am using Flash CS3 and targettting my application for Flash Player 9, I have installed Flash Player 10 on my machine. I am getting a flash player 10b.ocx error, which causes into crash of the browser. I am loading a bunch of images in this application. (20-30 at a time). using Loader class.
I have three questions: Is it the flash player error causing the browser to crash or something in my code is wrong?what possibly can go wrong in AS3 code to cause this error if it is not a flash player error?What could be the possible resolution for the same?
i managed to get my photogallery up and on my site but i'm having a problem. It loads a few of the pictures but then it quits working. After it quits working and i close the browser it gives me this error:
iexplore.exe - Application Error
The instruction at "0x10005f6c" referenced memory at "0x10005f6c". The memory could not be "read".
Click on OK to terminate the program You can go to [URL].. and try for yourself. Under the Pictures of Iraq page it should only load up till the 3rd picture. Anything after that and it quits working. Somebody please help me fix this.
I have tried to work my way through it.I can't understand why my button actions are causing an output error,the first two on this keyframe work just fine, but when I add the third it causes this error...

Here is the script
stop ();
function clickFunction(evt:MouseEvent):void {
gotoAndPlay(87, "Scene 1" );[code]........
Like I said, sg_btn and ak_btn work, but az causes the error...They are all on the same keyframe, dont know if that matters
I have a flash file and am using google's suggested method for as2 event tracking like so:
getURL("javascript:pageTracker._trackEvent('Refferal', 'Join', 'Benefits for HCAs/APs');");
The problem is that instead of silently communicating, pageTracker._trackEvent() appears to return a boolean value. Every time I click the button which this is located on I leave the page I was on and end up on a page that just contains the word "true".how to get around this? It makes the flash unusable.
I am a flash amateur. I have a movie clip in frame 1. The movie clip is a series of images that is similar to Apple's wait mouse cursor. I have written the following script hoping it will act as a preloader.
Code:
var total:Number = stage.loaderInfo.bytesTotal;
do {
var loaded:Number = stage.loaderInfo.bytesLoaded;
} while (loaded<total);
gotoAndPlay(3);
But, I get this error in the output window. Error: Error #1502: A script has executed for longer than the default timeout period of 15 seconds. All I can see is the preloader, but frame 3 is never loaded.
I am trying to use ZendAMF to do remote method calls to a MySQL database from Flash and I keep recieving the NetConnection.Call.BadVersion error.
My Server is working correctly. Apache 2.2.14
My PHP is working correctly. PHP 5.2.11
My Database is working. MySQL 5.0
My first problem was a security error in Flash. If you try to run a local SWF from the Flash IDE to a web service online, you'll get a security warning which will throw the BadVersion error. However, the security error won't show up if you 'TEST MOVIE' so it took me a while to realize that. I changed my testing process to remove this variable. I am now able to implement my php class code successfully using AMFPHP, which essentially rules out my class as the issue (I think). It seems to be a problem with the Zend implemntation of AMF.
I have followed a tutorial from Lee Brimlow here: [URL]. I was unable to get this to work locally, and I've moved my content onto a web server and can call the Class and Method from my SWF. I've used Charles to view the response. When I go to validate the response in Charles I get this:
Validator: Failed to Parse XML Document.
Reason: An invalid XML character (Unicode: 0x0) was found in the CDATA section.
Line: 65 Column: 87
Can it be handled in PHP?
Here is my ZendAMF code:
<?php
error_reporting(E_ALL|E_STRICT);
ini_set("display_errors", "on");
ini_set("include_path", "./frameworks");
require_once 'Zend/Amf/Server.php';
require_once 'Animal.php';

I have a movie that loads swfs into a loader within and MC on the main file/stage. The code within the movie clip housing the loader is (NOTE: I worked up an simplified fruits/veggies example to work out issues, I am not a fruit/veggie expert or anything):
[Code]....
That repeats every time either button is clicked after that. NOTE: I tested this after removing the preloader code(and moving the frames around to remove the blank first frame) in the external swfs and it worked fine jumping back and forth between them. I have already plugged away at this solving a series of issues to get to this point and I have the feeling this is a pretty simple fix, but I am not sure whether I should be looking in the external swf file itself or in the loader code in the main file to solve it.
