TypeError: Error #1009: Cannot Access A Property Or Method Of A Null Object Reference

TypeError: Error #1009: Cannot Access A Property Or Method Of A Null Object Reference
i created a preloader following the gotoandlearn.com tutorial, exactly as it is:


Code:
var l:Loader = new Loader();
l.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loop);
l.contentLoaderInfo.addEventListener(Event.COMPLETE, done);
l.load(new URLRequest("particles.swf"));

function loop(e:ProgressEvent):void {
var perc:Number = e.bytesLoaded / e.bytesTotal;
percent.text = Math.ceil(perc*100).toString();
}

function done(e:Event):void {
removeChildAt(0);
percent = null;
addChild(l);
}
and then i tried compiling it, and i get this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at particles_fla::MainTimeline/particles_fla::frame1()

particles file runs fine as a standalone, but not with the preloader
anyone knows what could it be?

TypeError: Error #1009: Cannot Access A Property Or Method Of A Null Object Reference
Hey,
Can anyone help me with this problem? I'm trying to make a little project for my studies, and i'm trying to create a little flash movie but I keep encountering a "TypeError: Error #1009".

So far i've come across with no problems until the point I added a new Listner onto the actions, which is for a button. Once I run the movie I came across with this problem:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at gallery_fla::MainTimeline/gallery_fla::frame1()


Code:
var currentColor:Number;

goCP.addEventListener(MouseEvent.CLICK,goCpanel);
btNext.addEventListener(MouseEvent.CLICK,goNextFrame);
btPrev.addEventListener(MouseEvent.CLICK, goBack);
changeColor.addEventListener(MouseEvent.CLICK, colorChange);
go.addEventListener(MouseEvent.CLICK,go1);

function go1(event:MouseEvent):void {
gotoAndStop(1);
}


function goCpanel(event:MouseEvent):void {
gotoAndStop('cpanel');
}

function goNextFrame(event:MouseEvent):void {
nextFrame();
}

function goBack(event:MouseEvent):void {
prevFrame();
}

function colorChange(event:MouseEvent):void {
var colorTransform:ColorTransform = gal.transform.colorTransform;
currentColor = cpColor.selectedColor
colorTransform.color = currentColor;
gal.transform.colorTransform = colorTransform;
gotoAndStop(1);

TypeError: Error #1009: Cannot Access A Property Or Method Of A Null Object Reference
First let me introduce myself. I'm Niassa and I'm pretty new to all of this. I did some basic Flash development way back in Flash 4, but didn't get into AS much at all. I have some basic OOP knowledge (C++, VB and a smidge of Java) so I'm not completely lost. This error I keep getting, however, is frustrating me like crazy, especially since I'm nearly copying it from a tutorial on this very thing (works great in the tut, not-so-much in my actual programming).

All I'm trying to do is basically get this movie clip to act as a button. When it is clicked I want it to go to the first frame of a different scene (in this instance it's the next scene, but I don't know that it will always be the next scene). I'm using the gotoAndStop function for this. The name of that frame is "Two" and the name of the scene is "Mid1." When I click on the movie clip, I get this error:

TypeError: Error #1009: Cannot Access A Property Or Method Of A Null Object Reference
I have kind of a problem with my loading external swf into my main swf... It works absolutely fine with any first movie I load to view its content and then unload... However when I try to load another movie I get the error message below. But my swf still loads and everything!
Since I'm learning AS3 I wanna understand the reason for that message and keep my code super tidy.

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at ExternalMovie1_fla::MainTimeline/stopScroll()

ExternalMovie1_fla being the swf I just loaded to view the content and then unloaded...

Also, here below is the code I use, see if I can add/correct anything. Or would it come from the way I load up my external movies?


ActionScript Code:
/** Load Function **/
swf1BTN.addEventListener(MouseEvent.CLICK, clickButton);
function clickButton(myevent:MouseEvent):void {
    var myrequest:URLRequest=new URLRequest("ExternalMovie1.swf");
    var myloader:Loader=new Loader();
    myloader.addEventListener("UnloadMe", unloadFunction);
    myloader.load(myrequest);
    stage.addChild(myloader);
    myloader.x=62;
    myloader.y=340;
}

/** Unload Function **/
function unloadFunction(event:Event):void {
    // event.target is the loader reference.. so cast it as Loader
    Loader(event.currentTarget).unload();
}

Then I have this code in my external swf, linked to a "close" button:

ActionScript Code:
CloseBTN.addEventListener(MouseEvent.CLICK, unloadFunction);
function unloadFunction(event:MouseEvent) {
    dispatchEvent(new Event("UnloadMe", true));
}

THANK YOU!!!

TypeError: Error #1009: Cannot Access A Property Or Method Of A Null Object Reference
Hi all

I'm trying to develop a KeyController class that's going to track which keyboard keys are being pressed.

My document class looks something like this:


ActionScript Code:
package {
   
    import flash.display.*;
    import flash.events.*;
   
    import KeyController;
   
    public class MyGame extends MovieClip{
       
        public var controller:KeyController;
       
        public function MyGame(){
            initKeyController();
        }
       
       
        public function initKeyController():void{
            controller = new KeyController();
        }
       
    }
   
}

And this KeyController class looks like:


ActionScript Code:
package{
   
    import flash.display.*;
    import flash.events.*;
   
    public class KeyController extends Sprite{
       
        public function KeyController(){
            stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDownListener);
            stage.addEventListener(KeyboardEvent.KEY_UP, keyUpListener);
        }
       
        public function keyDownListener(e:Event):void{
            trace("Key Down");
        }
       
        public function keyUpListener(e:Event):void{
            trace("Key Up");
        }
       
    }
   
}

My problem is I keep getting this error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at KeyController()
at MyGame/initKeyController()
at MyGame()

Which I think means I'm trying to access something in KeyController that isn't ready to be accessed. But I can't figure out what that is.

Any help is always appreciated.

Thanks
Chris

TypeError: Error #1009: Cannot Access A Property Or Method Of A Null Object Reference
I made a little particle engine for a project I'm working on, I have several particle sprites I wanna be able to use, and a single MovieClip that holds them all, each sprite in different frame, and I use this line to choose the sprite:


Code:
animRefMC.gotoAndStop(particleArray[j].sprite);
I get this error:

Code:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at particles::Particle_Manager/think()
at flash.utils::Timer/_timerDispatch()
at flash.utils::Timer/tick()
The weird thing is the code works perfectly, and this error only happens the first time I run the code after changing it.. lets say I changed the particleArray[j].sprite to something else, I run the code, I get the error, then I run it again without touching anything, and no error. Changed the frames position on the movieclip, running it, I get the error, running it again, no error.

What could be going on?

EDIT: Sometimes the error takes more times of re-running the code to disappear

TypeError: Error #1009: Cannot Access A Property Or Method Of A Null Object Reference.
Hello,

I have made a document class with a function in it to create buttons.
For these buttons I have also made a class.

This is the code from the button class:

// CameraButton klasse

package{
import flash.display.Sprite;
import flash.display.MovieClip;
import flash.display.Loader;
import flash.net.URLRequest;
import flash.events.*;

public class CameraButton extends Sprite{

private var topic:Topic;
private var huidig:Boolean;
private var ldrWFLoader;

public function CameraButton(topic:Topic, huidig:Boolean):void{
this.topic = topic;
this.huidig = huidig;
//om het handje weer te geven als je over het clickable item gaat
if(this.huidig==false){
this.buttonMode = true;
}

//eventlisteners toevoegen
this.addEventListener(MouseEvent.CLICK, clickHandler);
this.addEventListener(MouseEvent.ROLL_OVER, rollOverHandler);
this.addEventListener(MouseEvent.ROLL_OUT, rollOutHandler);

//loader van de images
if(this.huidig==false){
var imageLoader:Loader = new Loader();
imageLoader.load(new URLRequest("images/"+this.topic.naam+".png"));
addChild(imageLoader);
}else{
var imageLoader1:Loader = new Loader();
imageLoader1.load(new URLRequest("images/"+this.topic.naam+"Actief.png"));
addChild(imageLoader1);
}

}

private function clickHandler(evt:MouseEvent):void{
var ldrWFLoader = new SWFLoader();
ldr.addEventListener(SWFLoader.LOAD_DONE, showMovie);
ldr.laad(this.topic.naam+".swf");
}

private function showMovie(evt:Event):void{
var MCToShow:MovieClip = ldr.MC;
trace(MCToShow);
addChild(MCToShow);
}

private function rollOverHandler(evt:MouseEvent):void{
if(this.huidig==false){
var imageLoader:Loader = new Loader();
imageLoader.load(new URLRequest("images/"+this.topic.naam+"Actief.png"));
addChild(imageLoader);
}
}

private function rollOutHandler(evt:MouseEvent):void{
if(this.huidig==false){
var imageLoader:Loader = new Loader();
imageLoader.load(new URLRequest("images/"+this.topic.naam+".png"));
addChild(imageLoader);
}
}
}
}


The SWFLoader class is like this:

package{
import flash.events.*;
import flash.display.*
import flash.net.URLLoader
import flash.net.URLRequest
public class SWFLoader extends EventDispatcher{
public var MC:MovieClip;
public static const LOAD_DONEtring ="loaddone"
public function SWFLoader():void{
MC = new MovieClip();

}
public function laad(pathtring):void{
var req:URLRequest = new URLRequest(path)
var ldr:Loader = new Loader();
ldr.contentLoaderInfo.addEventListener(Event.COMPL ETE,contentLoaded)
ldr.load(req);
}

private function contentLoaded(evt:Event):void{
trace(evt.target.content);
trace("test6");
MC = MovieClip(evt.target.content);
//
dispatchEvent(new Event(SWFLoader.LOAD_DONE));
}
}

}

Does anybody know why i get this error and how to solve it:
TypeError: Error #1009: Cannot access a property or method of a null object reference

Thanks in advance.

Bram De Baets.

I searched through this forum and had 2 posts of same error however they didn't help me. I was making codes for buttons, all 5 buttons and instance named each and gave them which frame to go to.

First arrow button works but next second one doesn't work. Please let me know asap because i would like to keep working and finish this.

TypeError: Error #1009: Cannot Access A Property Or Method Of A Null Object Reference.
hello, i keep getting the "TypeError: Error #1009: Cannot access a property or method of a null object reference." error for the following function, and i know this error is usually about missing instances, but it doesn't make any sense.

the function runs properly as long as i'm in frame 40, but when the last bit executes, as soon it moves back to frame 30 i keep getting the error for the ucKontrol function, which doesn't make any sense because:

1) it shouldn't execute in frame 30, it should run only in frame 40
2) i removed the event listener at the last bit, so it shouldn't execute anywhere

could someone tell me what i'm doing wrong here, i feel really stupid because i'm probably missing something very basic. thank you

I am so new at Flash and I'm working on a Web site within Flash that may be over my head!

I have looked online for solutions to this problem and I have found some, but I don't understand how to apply them to my Flash movie because I'm just a beginner.

So, when I'm testing my movie, I'm getting an error that says:

Hello all I have a slight problem here which I guess it would be simple to solve but I need here your help because I am not able to figure it out for much that I try.

On my third line of code you can see a reference to a text field that gets loaded with some text retrieved from an XML file. There is a button "nextButton_mc", which will call a function that should retrieve the pertinent text from the next node in that XML. All code works fine except for the reference I make to that text field inside the nextSlides function. I do not know why it would not work with the same reference I made before: MovieClip(this.parent).myText.text

When I press the button that should retrieve the next piece of text I get this error: TypeError: Error #1009: Cannot access a property or method of a null object reference.

Obviously I am doing something wrong here.

I am very grateful for any help from you.

Andres.


PHP Code:



function linkEvent(evt:TextEvent):void {    linkText.removeEventListener(TextEvent.LINK, linkEvent);MovieClip(this.parent).myText.text=projectsXML.item[Number(evt.text)].desc;    nextButton_mc.addEventListener(MouseEvent.CLICK, nextSlides);    var index=[Number(evt.text)+1];    function nextSlides(e:MouseEvent) {        if (index<projectsXML.item.length()) {MovieClip(this.parent).myText.text=projectsXML.item[index].desc;                      }         index++;    }

[CS3] TypeError: Error #1009: Cannot Access A Property Or Method Of A Null Object Ref
I'm getting the error
TypeError: Error #1009: Cannot access a property or method of a null object reference

Everything still works ok until I add the stop Flv code then somethings work some don't.

Example of code for one button:


Code:
mc_altogether.mc_animation.addEventListener(MouseEvent.CLICK,animationin);

function animationin(e:Event):void {

mc_altogether.gotoAndStop("animation1");

}
mc_altogether.mc_animation.buttonMode = true;

Adding this: in the function messes it all up:
video1.stop();


This is the website:
http://nintendo.byethost7.com/portfolio/deskv3.html

It's the animation, interative and Illustration buttons that mess up.

I assume that the object which is null is related to all 3 but am unsure if this is a common error or just something stupid i am missing! If its any worth the script does use eventlisteners and i am suspicious this may be involved.

Can anyone point me in the right direction?

TypeError: Error #1009: Cannot Access A Property Or Method Of A Null Object Referenc
Hi,
I'm relativley new to ActionScript 3.0 and have to build a 3d-Carousel which loads external Pictures and places them as Carousel-"Objects" on the stage. I tried to accomplish this through combining tutorials: an external LoaderClass which loads the Pictures and a MainClass which places Pictures on the Stage and rotates them through a 3d-Engine. In addition the Carousel rotates in relation to mousemoving and places the clicked Container to the front.
Finally the Pictures are placed correctly but the Carousel is rotating very slowly and every Frame i get this Errormessage:

TypeError: Error #1009: Cannot access a property or method of a null object reference:

I'm lost and would appreciate your help.


Here is the Code:

Error #1009 Cannot Access A Property Or Method Of A Null Object Reference.
Someone has probably already answered this question in another forum, but I couldn't find a solution. I have a .swf that is loading other .swfs. Everything works fine when I run it in Flash Player, but once I embed the swf into an html I get Error #1009...

Does anyone know why this would happen in an html an not in flash player?

If I press continue the code seems to run just fine, but I don't want this error to create panic in those who will view the page. Plus, the fact that I get this error makes me think something is not working right.

Error #1009: Cannot Access A Property Or Method Of A Null Object Reference
This is driving me insane! Hopefully someone here can help. I've been given what is a mess of timelined and AS files actionscript and have managed to solve my way through most of it after much hrs. This has me stumped though, i'm still new at AS3.

When clicking on a button that is to load an external swf i get the following errors:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at main_fla::MainTimeline/loadBigImg()
at main_fla::left_19/mapBtn()
TypeError: Error #1009: Cannot access a property or method of a null object reference.

at AS::BigImage/setLG()
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at AS::BigImage/imgLoaded()



i've checked all of these and from what i can understand it's trying to make a reference before the object / reference is available ?

Here is the loadBigImg() function:


ActionScript Code:
function loadBigImg(bigSrc:String):void {
    content_mc.h.stopAnimation();
    home.mouseChildren = false;
    TweenFilterLite.to(home, .5, {type:"Blur", blurX:8, blurY:8, ease:Sine.easeOut, quality:2});
    TweenFilterLite.to(home, .5, {type:"color", colorize:0xFFFFFF, amount:1, brightness:2, overwrite:false});
    var bImg:BigImage = new BigImage(bigSrc);
    parent.parent["BigImageHolder"].addChildAt(bImg, 0);
    parent.parent["BigImageHolder"].alpha = 1;
    parent.parent["BigImageHolder"].addEventListener(MouseEvent.CLICK, bigImgOff);
    parent.parent["BigImageHolder"].buttonMode = true;
    parent.parent["BigImageHolder"].mouseChildren = false;
}

Here is the mapBtn() function:


ActionScript Code:
function mapBtn(evt:MouseEvent):void {
    if(evt.type == MouseEvent.CLICK) {
        MovieClip(parent).loadBigImg("map.swf");
    }
}

Here is the setLG() function:


ActionScript Code:
public function setLG(evt:ProgressEvent):void {
    lg.x = stage.stageWidth/2-lg.width/2;
    lg.y = stage.stageHeight/2-lg.height/2;
}

and finally ....


ActionScript Code:
public function imgLoaded(evt:Event):void {
    removeChild(lg);
    /*bmpData = new BitmapData(ld.width, ld.height, true, 0x00000000);
    bmpData.draw(ld);
    bmp = new Bitmap(bmpData, "auto", true);*/
    ld.alpha = 0;
    ld.x = stage.stageWidth/2-ld.width/2;
    ld.y = stage.stageHeight/2-ld.height/2;
    addChild(ld);
    TweenLite.to(ld, .15, {alpha:1});
}

Any help with this will be GREATLY appreciated. All it needs to be doing is loading in a damn swf when a button is clicked, and unloading it when something else is clicked.

Error #1009: Cannot Access A Property Or Method Of A Null Object Reference.
I have searched this error over and over and I can't seem to find a good response as to what this means. More specific to what I am working on now, is I am working on a site using PureMVC, and I am getting this very non-descriptive error "Error #1009: Cannot access a property or method of a null object reference." I am using very similar code to the one in this tutorial (http://hubflanger.com/building-a-fla...using-puremvc/) and I don't get an error with that code.

Here is my code:


ActionScript Code:
var siteHolder : SiteHolder = new SiteHolder();
           
try
{
     facade.registerMediator (new SpiralMediator( siteHolder ));   
}
     catch ( error: Error)
{
     trace(error.message); 
}

I traced the facade instance and it exists, I traced the siteHolder instance and it exists, and I tried instantiating the SpiralMediator separately and it worked, so I have come down to the solution that the registerMediator Method is not working. However, I traced it, and it seems to be working. Anyone have any suggestions?

Error #1009: Cannot Access A Property Or Method Of A Null Object Reference.
Hello,

Please help, this is a tricky one to explain, but hopefully someone out there will be able to understand the problem I am having and be able to shed some light on the matter.

Okay, so I have quite a large naviagtional flash .swf. It is created on the timeline, with some elements added dynamically and others are on the stage.

I have a menu naviagtion bar on each frame, these are buttons and if clicked send you to the corresponding frame by gotoAndStop commands. The only other code in these functions are the removeChild(); commands required for each frame. This works up to a point, however every now and then I keep getting the error message below:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at TestingVersion5_fla::MainTimeline/TestingVersion5_fla::frame3()

This is a pain because it does not tell me specifically where the error is so I dont know what to change, what is also annoying is that this error seems to appear randomly with no connection as to which button is being pressed at the time, I should also mention, when this error is displayed, one of the buttons on the stage becomes invisible.

Anyone any ideas how I can perhaps fix this one? Would adding these navigation buttons dynamically help in any way?

Many thanks

It is greatfully appreciated.

Error #1009:Cannot Access A Property Or Method Of A Null Object Reference. [renamed]
Hi, i made a class that creates some sprites and make all those spectrum analyzer effects
when i use this class as the document class of an swf file, it works fine, but if i try to create an instance of this class inside another one, o got this message


TypeError: Error #1009: Cannot access a property or method of a null object reference.
at com.chan.graphics::OvalSpectrumAnalyzer$iinit()
at com.chan.graphics::Teste/com.chan.graphics::frame1()

i don´t understand the explannation on the reference related to this error...

what am i doing wrong, and how can i create an instance of this class?

one thing that i didn't understand is what means the null object reference

can anyone tell me what´s wrong with my class?

thanks

Pong Game: GotoAndStop Causing Error #1009: Cannot Access A Property Or Method Of A Null Object Reference.
I'm building a pong game as a way of learning Flash and actionscript 3. Almost have it done.

The game consists of 4 frames: begin, play, win, and lose.

The code for begin works fine and the code for win and lose is the same so I will concentrate on the code for play and lose.

The actual game code in play works fine. Collision detection, score tracking, player paddle movement, AI paddle movment, etc. But there is one problem.

Problem: After the player or the computer gets to 5 points the game is supposed to go to the win or lose frame. I use gotoAndStop for this: gotoAndStop("lose"). This is where I get the "Error #1009: Cannot access a property or method of a null object reference."

From what I can tell it has to do with the gotoAndStop statements that take the player to the win or lose frame. I say this because if I add an End button with an event listener and function call in place of either gotoAndStop statement the End button works properly. It takes me to the win or lose frame (depending on which I target) without an error. But only putting gotoAndStop("frame") in the if statement gives me the error. I want the program to automatically go to the win or lose frame based on the score. I do not want the user to have to click anything.

The code I'm using for the play and lose frames is below.

Any thoughts?

Curious: TypeError: Error #1009: Cannot access a property or method of a null object
Hey guys

i get the following error in AS3::

----
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at main/main::init3d()
at PaperBase/init()
at main$iinit()

I assume that the object which is null is related to all 3 but am unsure if this is a common error or just something stupid i am missing! If its any worth the script does use eventlisteners and i am suspicious this may be involved.

Can anyone point me in the right direction?
Cheers

#1009: Cannot Access A Property Or Method Of A Null Object Reference.
I've googled this error a ton but haven't found anything relevant yet. I'm in an AS 3.0 class (as in a room with people and a teacher and text books and lectures .. not a class file) and we're all getting the same errors.

Basically we all have to create a file with 10 buttons. Each button needs to go to a new frame. On that frame we have a separate actionscript 3.0 code that does something (for this question, I do not think it matters... each script on each frame has to show off a different AS 3.0 code that proves we've learned something).

So let's say we have 11 frames. Frame 1 has the navigation and the intro. Frames 2-11 each have a stop(); and a new code.

So each frame has different content (except for the background and navigation buttons which are consistent on all frames).

The problem is that on one frame we have an ENTER_FRAME on a movie clip that points to a specific function. On that particular frame it works fine but once you navigate to a new frame on the timeline - the function continues to run in the background and we get the "#1009: Cannot access a property or method of a null object reference" error. (I assume it's because on the new frame the content from the previous frame no longer exists. By content I mean the movie_clips/buttons/etc..)

Once the functions start to run on top of each other in the background - the entire SWF just devolves and breaks down because it's trying to do too many things at once.

removeListener seems like the obvious answer but on each new frame it generates an error because it can't see the content from the previous frame on which the Listener was added. Putting it on the navigation button codes doesn't seem to work either.

Any theoretical suggestions?

TextArea And Error #1009: Cannot Access A Property Or Method Of A Null Object Referen
Hi. I get this error when I try to display a TextArea. All I see is the text, no border or scroll bar. The odd thing is, I have another TextArea in a different part of the code that works. The instance parameters in the .fla file are identical between the two and in the code, all I'm doing for each is assigning the text (textAreInstance.htmlText = "...").

Any ideas on why this is happening?

Please PLease Help [TypeError: Error #1009: Null Object Reference]
Hello I am making an OOP scroll bar. I have three classes

1. ScrollBox

This class contains the scroll bar and a container that hold the images to be scrolled.

2. Scroll Bar

This class controls the scrolling of the bar and dispatches a scrollbar event containing the percentage to which the thumb bar is moved.

3. ScrollBarEvent class.

This class simply fires an event with the event object containing the percentage of the scroll bar scrolling.

Now Everything was running fine when it was on the stage but as I moved the code in classes it give a TYPE ERROR 1009 saying it cant access a property or method of null object reference.

The error comes when I create an object of scroll bar inside the scroll box class. I am pasting the code for the classes below.

SCROLL BAR Class

Code:
package
{
import flash.display.*;
import flash.events.*;

public class ScrollBar extends MovieClip
{
private var xOffset:Number;
private var xMin:Number;
private var xMax:Number;

public function ScrollBar():void
{
xMin = 0;
xMax = track.width - thumb.width;

thumb.addEventListener(MouseEvent.MOUSE_DOWN, thumbDown);
track.addEventListener(MouseEvent.MOUSE_DOWN, trackDown);
stage.addEventListener(MouseEvent.MOUSE_UP, thumbUp);

}
public function trackDown(e:MouseEvent):void
{
//stage.addEventListener(MouseEvent.MOUSE_MOVE, thumbMove);
//yOffset = mouseY - thumb.y;

thumb.x = mouseX ;

if (thumb.x <= xMin)
{
thumb.x = xMin;
}
if (thumb.x >= xMax)
{
thumb.x = xMax;
}
dispatchEvent (new ScrollBarEvent(thumb.x / xMax));
}

private function thumbDown(e:MouseEvent):void
{
stage.addEventListener(MouseEvent.MOUSE_MOVE, thumbMove);
xOffset = mouseX - thumb.x;
}

private function thumbUp(e:MouseEvent):void
{
stage.removeEventListener(MouseEvent.MOUSE_MOVE, thumbMove);
}

private function thumbMove(e:MouseEvent):void
{
thumb.x = mouseX - xOffset;
if (thumb.x <= xMin)
{
thumb.x = xMin;
}
if (thumb.x >= xMax)
{
thumb.x = xMax;
}

dispatchEvent (new ScrollBarEvent(thumb.x / xMax));
e.updateAfterEvent();
}
}//end of class
}// End of package
ScrollBox Class


Code:
package
{
import flash.display.*;
import flash.events.*;
import caurina.transitions.*;
public class ScrollBox extends MovieClip
{
private var scrollBar:ScrollBar;
private var masker:Masker;
private var content:Content;

public function ScrollBox():void
{
scrollBar = new ScrollBar();

scrollBar.x = 100;
scrollBar.y = 50;

addChild(scrollBar);

scrollBar.addEventListener(ScrollBarEvent.VALUE_CHANGED, sbChange);

}

public function sbChange(e:ScrollBarEvent):void
{
Tweener.addTween(content, {x:(-e.scrollPercent*(content.width - masker.width)), time:1});
}

}//end of class
}// End of package
Scroll bar movie clip is in the library and contains two movieclips one with instance name thumb and another one with name track.

Can anyone please help I have really given up on this now Thanks in advance

How To Correct This; TypeError: Error #1009: Cannot Access A Property Or Method Of..
hi again everybody.


after I saw the idea of class'es, I've been very exited about the idea.
but as this area is very new to me, I have big trouble completing my classes.

here's an example.
I'm working on a IndexPreloader - a preloader, that loads the .swf itself.
and so far I've managed to make the graphics to be used as a bar.
but when I try adding a TextField, I get this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.


here's what I've written in my .fla so far:

Code:
stop();

//set up the IndexPreloader class
import IndexPreloader;
var indexPreloader:IndexPreloader = new IndexPreloader();
addChild(indexPreloader);
// now the stage property of makeStars is no longer null

loaderInfo.addEventListener(ProgressEvent.PROGRESS, progressEvent);
loaderInfo.addEventListener(Event.COMPLETE, doneLoading);

//functions
function progressEvent(e:ProgressEvent):void {
//bytesTotal, bytesLoaded, farve
indexPreloader.init(e.bytesTotal, e.bytesLoaded, 0x000000);
indexPreloader.doTheGraphics();
}

function doneLoading(e:Event):void {
trace("done loading");
gotoAndStop(2);
}

and here's the code in my .as-file:

Code:
package {

import flash.display.Sprite;
import flash.text.TextField;

public class IndexPreloader extends Sprite {
private var bytestotal:Number;
private var bytesloaded:Number;
private var color:uint;
private var backgroundGraphic:Sprite = new Sprite();
private var preloadGraphic:Sprite = new Sprite();
private var sclbar:Number;
private var isInitiated:Boolean = false;
private var textfield:TextField;

public function IndexPreloader() {

}
public function init(bytesTotally:Number, bytesToLoad:Number, colorToUse:uint):void {
bytestotal = bytesTotally;
bytesloaded = bytesToLoad;
color = colorToUse;
trace("completion = "+bytesloaded+" / "+bytestotal);
sclbar = Math.round(bytesloaded/bytestotal * 100) * 2; //goes from 0 to 200, which equals the preloaders width
if (bytesloaded >= bytestotal) {
trace("bytesloaded >= bytestotal");
}
}
public function doTheGraphics():void {
if (isInitiated == false) {
isInitiated = true;
backgroundGraphic.graphics.lineStyle(0, 0, 0);
backgroundGraphic.graphics.beginFill(color);
backgroundGraphic.graphics.lineTo(200, 0);
backgroundGraphic.graphics.lineTo(200, 20);
backgroundGraphic.graphics.lineTo(0, 20);
backgroundGraphic.graphics.lineTo(0, 0);
backgroundGraphic.graphics.endFill();
backgroundGraphic.alpha = 0.1;
backgroundGraphic.x = ((this.stage.stageWidth/2) - (backgroundGraphic.width/2));
backgroundGraphic.y = ((this.stage.stageHeight/2) - (backgroundGraphic.height/2));
addChild(backgroundGraphic);
//
preloadGraphic.graphics.lineStyle(0, 0, 0);
preloadGraphic.graphics.beginFill(color);
preloadGraphic.graphics.lineTo(200, 0);
preloadGraphic.graphics.lineTo(200, 20);
preloadGraphic.graphics.lineTo(0, 20);
preloadGraphic.graphics.lineTo(0, 0);
preloadGraphic.graphics.endFill();
preloadGraphic.alpha = 1;
preloadGraphic.x = backgroundGraphic.x;
preloadGraphic.y = backgroundGraphic.y;
addChild(preloadGraphic);
//
/*textfield.text = sclbar+" % loaded";
textfield.border = true;
textfield.width = 400;
textfield.height = 200;
textfield.selectable = false;
addChild(textfield);
trace(textfield.x);*/
}
preloadGraphic.width = sclbar; //here we increment width with sclbar number form init function
}
}
}

as long as the part about the textfield in the end of the doTheGraphics-function is not compiled, nothing seems to be a problem.
but if I complie it, I get this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.


but to me it makes no sense (obviously )
because the textfield is defined at the same time of the 2 graphics, and the textfield is added to the stage in the same way the 2 graphics are...
so in my head, it ought to work perfectly!


can anyone tell me, what I'm doing wrong?

thanks

Error #1009: Cannot Access A Property Or Method Of A Null...
Yep, I've found this is an infamous error msg and I've actually fixed it the first time it appeared. However, I'm not sure how to deal with it with the new field it's complaining about.

Forgive me, this is my first actionscript where I'm using a main file and its' companion package file. My very first actionscript, well I had all my code in one file and then noticed example code in tutorials were separated in packages. So, I have split off my one file into the convention where the class is in an external file but now, I am encountering the 1009 type error.

In short, I'm trying to add a sprite using an external jpg file and also added in a function so that I can move it. I put all loads and move function in the class package file. The error is that when I try to access the "addEventListener" statement, I encounter the error listed in the title. The error message (complete) is:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at asdata::Bumper()
at bumper_fla::MainTimeline/frame1()

The main file code is:

import asdata.Bumper;
var myBumper:Bumper = new Bumper();

The class package file is:


ActionScript Code:
package asdata{
import flash.display.*;
import flash.net.URLRequest;
import flash.events.*;
 
public class Bumper extends Sprite{
 
private var bumper:Sprite = new Sprite();
private var loader:Loader = new Loader();
private var rq:URLRequest = new URLRequest("bumper.png");
 
public function Bumper() {
trace("entered new bumper creation");
 
loader.load(rq);
this.loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadBumper);
//next statement is where the error occurs.
//I think it's having a problem accessing stage because
//it is null but I don't know what to do to fix this.
stage.addEventListener(MouseEvent.MOUSE_MOVE,moveBumper);
}
 
 
function loadBumper(event:Event):void {
var bumperImage:BitmapData = new BitmapData(loader.width,loader.height,false,0x000000);
bumperImage.draw(this.loader);
 
this.bumper.graphics.beginBitmapFill(bumperImage, null, true);
bumper.graphics.drawRect(0,0,100,10);
bumper.graphics.endFill();
bumper.x = 10;
bumper.y = 290;
addChild(bumper);
}
 
 
function moveBumper(e:MouseEvent):void {
bumper.x = e.stageX - bumper.width;
}
}
}

How do I substantiate stage before accessing it? Or am I analyzing this error incorrectly? Also, when I had the code all in one file, a picture actually appeared when it executed the 'addChild' statement. However, now that I've separted the code into 2 files (main with .as file), nothing appears after the addChild is executed. :x Am I wrong to assume that anything added to the display list in a class will not appear? What am I doing wrong here, too?

Any help is appreciated,
Marion the Mighty Confused

P.S. I'm sorry the program isn't indented correctly, the editor stripped out my tabs and extra spaces.

Cannot Access A Property Or Method Of A Null Object Reference
I am getting this error:

Code:

at Main$iinit()
I used the same code on another fla and it worked so it's the fla. I just don't know what it means.

The only difference I have on the non working fla is that the button is on frame 50 and the working fla is just 1 frame long.


Thanks a bunch!

Cannot Access A Property Or Method Of A Null Object Reference
Here's my problem.

I'm adding a movie clip via linkage to the stage through addchild.

the movieclip has a handful of labels along the time line all with different movieclips with which are to become clickable buttons and dynamic text fields which are to be filled.

HOWEVER!

When ever I tell the movie to gotoAndStop to the next required label, I then follow by telling it what all the buttons should do, and what should be in the text fields.

My problem is, the buttons and text fields are all :-


Quote:




TypeError: Error #1009: Cannot access a property or method of a null object reference




Basically - the code doesn't know they are there yet. A hack is to add an event listener that waits until the buttons are objects and then give them their functions. But this seems so uneccessary and cumbersome, if I have to do it for every label along the movie.

What am I missing? This is how the movieclip is being added:

public var highscores:MovieClip = new Highscores();
addChild(highscores);
highscores.x = 145;
highscores.y = -highscores.height;


Is their another way to target embedded movieclips along the timeline of an imported movieclip?

Is their a method I can pre-register the movieclips and text fields? without putting them all on the first frame of the imported movieclip?

Cannot Access A Property Or Method Of A Null Object Reference
Argh! I hate this Error! It doesn't tell me where it occurs, and it explains nothing!
I ran in debug through the entire code, the error happens only when after all of the code ran through. And then it tells me that it cannot display the source code at the locations which makes the Error!

Cannot access a property or method of a null object reference.
at main_fla::MainTimeline/main_fla::frame1()

What can cause the error? I don't remove any MC or anything like that..

Here's my code at frame1:

var main:Main = new Main();

main.loadPage("main.swf");

Cannot Access A Property Or Method Of A Null Object Reference?
I'm confused at what is causing this error. My code seems to work for the first two links and then stops when it hits the third link.

I'm attempting to create a transition in effect for my links which can be easily achieved on the timeline but would like to understand how to do all of this through code.

The effect is just fade in each link one at a time while moving each link about 20 pixels higher while fading in.


ActionScript Code:
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;

var home:Home_btn = new Home_btn();
addChild(home);
var about:About_btn = new About_btn();
addChild(about);
var register:Register_btn = new Register_btn();
addChild(register);
var schedule:Schedule_btn = new Schedule_btn();
addChild(schedule);

//setup link  tween var
var homeAlpha:Tween;
var homeY:Tween;
var aboutAlpha:Tween;
var aboutY:Tween;
var registerAlpha:Tween;
var registerY:Tween;
var scheduleAlpha:Tween;
var scheduleY:Tween;

//set x values of links
home.x = 378;
about.x = 517;
register.x = 665;
schedule.x = 788.5;

//set link initial alpha to 0
home.alpha = 0;
about.alpha =0;
register.alpha =0;
schedule.alpha =0;

homeAlpha = new Tween(home, "alpha", Strong.easeOut, 0, 1, 1, true);
homeY = new Tween(home, "y", Strong.easeOut, 43, 37, 1, true);


homeY.addEventListener(TweenEvent.MOTION_FINISH, aboutStart);
function aboutStart(event:TweenEvent):void
{

aboutAlpha = new Tween(about, "alpha", Strong.easeOut, 0, 1, 1, true);
aboutY = new Tween(about, "y", Strong.easeOut, 43, 37, 1, true);
}

aboutY.addEventListener(TweenEvent.MOTION_FINISH, registerStart);
function registerStart(event:TweenEvent):void
{

registerAlpha = new Tween(register, "alpha", Strong.easeOut, 0, 1, 1, true);
registerY = new Tween(register, "y", Strong.easeOut, 43, 37, 1, true);
}

registerY.addEventListener(TweenEvent.MOTION_FINISH, scheduleStart);
function scheduleStart(event:TweenEvent):void
{

scheduleAlpha = new Tween(schedule, "alpha", Strong.easeOut, 0, 1, 1, true);
scheduleY = new Tween(schedule, "y", Strong.easeOut, 43, 37, 1, true);
}


Thanks!

Cannot Access A Property Or Method Of A Null Object Reference
Hi All,

I´m stucked with "Cannot access a property or method of a null object reference"

I did a small test inside the IDE and it works fine


PHP Code:



var _container:Sprite;var holder:Sprite = new Sprite();addChild( holder ); PainelNumeros( holder );function PainelNumeros(mc:Sprite){ _container = new Sprite(); draw(); mc.addChild(_container);}function draw():void{ var origX = 23; var origY = 126.5; var deltaX = 24.5; var deltaY = 17.9; var larguraBox = 17.8; var alturaBox = 9.4; var posX = origX; var posY = origY; var elemento = 0; for (var i = 1; i <= 10; i++) {  for (var j = 1; j <= 10; j++)  {   var nome = "numero" + elemento ;    _container.addChild( new SpriteBox() ).name  = nome;   _container.getChildByName( nome ).x = posX;   _container.getChildByName( nome ).y = posY;   _container.getChildByName( nome ).width = larguraBox;   _container.getChildByName( nome ).height = alturaBox;   _container.getChildByName( nome ).alpha = 0.5;   _container.getChildByName( nome ).addEventListener(MouseEvent.CLICK, mouseClickHandler);   posX += deltaX;   elemento++;  }  posX = origX;  posY += deltaY; }}function mouseClickHandler(event:MouseEvent){ trace( event.target.parent.name );}................................................................package { import flash.display.*; import flash.events.*; public class SpriteBox extends Sprite {  private var size:uint = 50 ;  private var status:Boolean;  private var bgColor:uint = 0xFFCC00;  public function SpriteBox()  {   var child:Sprite = new Sprite();   status = false;   draw(child);            addChild(child);  }  private function draw(sprite:Sprite):void  {   sprite.graphics.beginFill(bgColor);   sprite.graphics.drawRect(0, 0, size, size);   sprite.graphics.endFill();  } }} 




Then I tryed to translate what I got through the IDE to a new class


PHP Code:



package { import flash.display.*; import flash.events.*; public class PainelNumeros {  private var _container:Sprite;  public function PainelNumeros(mc:Sprite)  {   var _container:Sprite = new Sprite();   draw();   mc.addChild(_container);  }  private function draw():void  {   var origX = 23;   var origY = 126.5;   var deltaX = 24.5;   var deltaY = 17.9;   var larguraBox = 17.8;   var alturaBox = 9.4;   var posX = origX;   var posY = origY;   var elemento = 0;   for (var i = 1; i <= 10; i++)   {    for (var j = 1; j <= 10; j++)    {     var marca:SpriteBox = new SpriteBox();     var nome = "numero" + elemento;     _container.addChild( new SpriteBox() ).name  = nome;     _container.getChildByName( nome ).x = posX;     _container.getChildByName( nome ).y = posY;     _container.getChildByName( nome ).width = larguraBox;     _container.getChildByName( nome ).height = alturaBox;     _container.getChildByName( nome ).alpha = 0.5;     _container.getChildByName(nome).addEventListener(MouseEvent.CLICK, mouseClickHandler);     posX += deltaX;     elemento++;    }    posX = origX;    posY += deltaY;   }  }  private function mouseClickHandler(event:MouseEvent)  {   trace( event.target.parent.name );  } }} 




and tryed to instantiate it in the IDE


PHP Code:



var holder:Sprite = new Sprite();addChild( holder ) ; var painel1:PainelNumeros = new PainelNumeros ( holder ) ; 




Where I get the error, what am I doing wrong ?

thanks in advance

Cannot Access A Property Or Method Of A Null Object Reference.
Why is it that ActionScript Code:
getChildByName("instance390").visible=false;

works and ActionScript Code:
getChildByName("Promotion1").visible=false;

give this error:

ActionScript Code:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at MethodInfo-98()







ActionScript Code:
getChildByName("Promotion1").visible=false;

works well in the FLA timeline. But not in the class. It's parent is the main timeline


Fla:
ActionScript Code:
import image.imageContainer;
var promoHolder:Array = new Array();
for (var i:int = 1; i < 5; i++) {
this['Promotion'+i] = new imageContainer("images/Promo"+i+".swf","loader.swf");
promoHolder[i] = this['Promotion'+i];
promoHolder.push(this['Promotion'+i]);
addChild(promoHolder[i]);
promoHolder[i].name = "Promotion" +i;


}

function test():void{
}

var Promotion1:MovieClip = MovieClip(getChildByName("Promotion1"));
var Promotion2:MovieClip = MovieClip(getChildByName("Promotion2"));
var Promotion3:MovieClip = MovieClip(getChildByName("Promotion3"));
var Promotion4:MovieClip = MovieClip(getChildByName("Promotion4"));

//Promotion1.visible=false;
Promotion2.visible=false;
Promotion3.visible=false;
Promotion4.visible=false;



Class:
ActionScript Code:
...
function handleClick(event:MouseEvent):void {
trace(event.currentTarget.name);

getChildByName("instance390").visible=false;
getChildByName("Promotion1").visible=false;
}
...
