Flash Error #1009 on mouse click - actionscript-3

I have a movie clip called AndroidEye2, which has 4 frames.
I have this code on my 'Main Menu' Scene:
function eye1(e){
AndroidEye2.gotoAndStop(2);
}
function standStill(e){
AndroidEye2.gotoAndStop(1);
}
ViewMerchandise_IconB.addEventListener(MouseEvent.CLICK,ViewMerchandise1);
function ViewMerchandise1(e) {
gotoAndPlay(1,"ViewMerchandise1");
}
ViewMerchandise_IconB.addEventListener(MouseEvent.MOUSE_OVER, eye1);
ViewMerchandise_IconB.addEventListener(MouseEvent.MOUSE_OUT, standStill);
I have this error
TypeError: Error #1009: Cannot access a property or method of a null
object reference. at Tes_fla::MainTimeline/standStill()
Every time I try to click the ViewMerchandise_IconB button. What did I do wrong?
I'll send you the fla file if you needed to see the error.

The application is complaining about "AndroidEye2.gotoAndStop(1);" It says that AndroidEye2 (that specific instance or static class (depending on what it is)) does not have any property/function called "gotoAndStop". It could also be that AndroidEye2 is null/undefined when that function (standStill) is called.
Edit1:
standStill(e){
trace("instance=" + AndroidEye2);
trace("function=" + AndroidEye2.gotoAndStop);
AndroidEye2.gotoAndStop(1);
}

TypeError: Error #1010: A term is undefined and has no properties?

Error:
TypeError: Error #1010: A term is undefined and has no properties. at Untitled_2_fla::MainTimeline/frame1()[Untitled_2_fla.MainTimeline::frame1:4]
Can't seem to figure out what's that about.
Here's my code:
import flash.events.MouseEvent;
btnMc1.txtSourceMc.gotoAndStop();
btnMc1.addEventListener(MouseEvent.ROLL_OVER, over);
btnMc1.addEventListener(MouseEvent.ROLL_OUT, out);
function over(e: MouseEvent) {
btnMc1.buttonMode = true;
btnMc1.gotoAndPlay(1);
}
function out(e: MouseEvent) {
btnMc1.gotoAndPlay(62);
}
You need to create the variable btnMc1, such as var btnMc1 And you're going to have to give it a class such as var btnMc1:
whatEverObjectICreated = new whatEverObjectICreated;
btnMc1.txtSourceMc.gotoAndStop();
Change that to
btnMc1.txtSourceMc.gotoAndStop(1);
Make sure that you've named you MCs correctly. Firstly, go to your stage, and click on btnMc1. Make sure you've name it as such in the properties panel(windows -> properties). Next, double click onto btnMc1 and do the same for txtSourceMc, make sure that it has the correct name. Im assuming that you have txtSourceMc inside btnMc1 on the timeline.
If the problem persists, it is probably because whatever you're loading into btnMc1 or txtSourceMc is too huge. So it cannot instantiate on the frame you're trying to call it in this code, thus it returns as undefined.
To solve this, right click onto btnMc1 from the library and select properties. Then select export for actionscript and make sure that the box for exporting on frame1 is checked. Do the same for txtSourceMc.

error #1009 can't access property of null object

i'm newbie here i got an eror where i can't load external swf from my main fla the ouput said like this
`TypeError: Error #1009: Cannot access a property or method of a null object reference.
at com.senocular.utils::KeyObject/construct()
at com.senocular.utils::KeyObject()
at com.asgamer.basics1::Ship()

I create a button and tried to load swf file called basics1 which content all those classes above, and i using action code snippet to load swf file
please help i'm not a programmer sorry if my question in easy
the problem is fix by adding this
if(stage) {
initialize();
} else {
addEventListener(Event.ADDED_TO_STAGE,initialize);
}
}
private function initialize(e:Event = null):void {
removeEventListener(Event.ADDED_TO_STAGE,initialize);
// here goes the code that's currently in Engine constructor
}
after public function engine

How to refer to a single frame in a an object class?

So, I have my character movieclip on frame1 of my timeline. When it hits an enemy the movie goes on frame2 where I have a game-over screen. However I get this error at runtime when the character hits the enemy:
TypeError: Error #2007: Parameter hitTestObject must be non-null.
at flash.display::DisplayObject/_hitTest()
at flash.display::DisplayObject/hitTestObject()
at Coinsy/update()
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Untitled_2_fla::MainTimeline/CharMovement()
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Untitled_2_fla::MainTimeline/ResetBox()
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Untitled_2_fla::MainTimeline/EnemyBall()
I debugged and it seems that the problem is in my coins class:
package
{
import flash.display.*;
import flash.events.*;
public class Coinsy extends MovieClip
{
var char:MovieClip;
var MTL = MovieClip(root);
public function Coinsy()
{
this.addEventListener(Event.ENTER_FRAME, update);
}
function update(event:Event):void
{
char = MTL.char1;
// CC = int(root).CC;
if(hitTestObject(char))
{
this.removeEventListener(Event.ENTER_FRAME, update);
parent.removeChild(this);
MTL.CC++;
}
}
}
}
at char = MTL.char1;, apparently I can't use MovieClip(root) when I have more then one frame.
char1 is my character's instance name andCC is the coin count var.
I'm pretty new at ActionScript and I'd like to know where i did wrong. THANKS!
The error is actually happening on this line
if(hitTestObject(char))
What's happening is the game is still trying to check for collisions on the game-over screen. The char1 object couldn't be found, so it became null. Null essentially means something's empty, so you can't do anything with it. If you ever try null.something you'll get an error, and someFunction(null) will quite likely cause an error too.
A quick fix is changing the line to
if(char != null && hitTestObject(char))
as Karma mentioned.
However, the following three TypeErrors are unrelated to the code you posted. They're happening because some line of code is trying to do null.something. The CharMovement, ResetBox and EnemyBall functions are probably being called when they shouldn't be. You might need to remove event listeners when game-over happens, or add extra logic to check for null values.

How to fix AS3 TypeError: Error #1009: Cannot access a property or method of a null object reference?

I am getting this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Skool_fla::MainTimeline/frame1()[Skool_fla.MainTimeline::frame1:10]
at flash.display::MovieClip/gotoAndStop()
at Skool_fla::MainTimeline/goback()[Skool_fla.MainTimeline::frame2:22]
What is causing this error and how do I fix it?
This is my code for both the frames:
Frame 1: This is the main menu screen where you can access the credit section
import flash.events.MouseEvent;
//setting up the variables
//events
//stop the timeline
stop();
//the play button
play_btn.addEventListener(MouseEvent.CLICK, playani);
function playani(e:MouseEvent)
{
//asking it to progress to the load menu
gotoAndStop(3);
}
//the credits button
credit_btn.addEventListener(MouseEvent.CLICK, creditslide);
function creditslide(e:MouseEvent)
{
//asking it to go the credits frame
gotoAndStop(2);
}
Frame 2: This is where the credits appear
//
//
//all the imports
//events
var credit:credits_bck = new credits_bck ();
var credits_name: credit_nm = new credit_nm ();
var back_butn: back_button = new back_button ();
addChild (credit);
addChild (credits_name);
addChild (back_butn);
back_butn.addEventListener(MouseEvent.CLICK,goback);
function goback(G:MouseEvent)
{
removeChild (credit);
removeChild (credits_name);
gotoAndStop(1);
}
Either play_btn or back_butn is null. Your error message's line numbers don't correspond to your code so it's hard to say. But the gist is you're trying to access a property of something that isn't anything. Check to make sure you're initializing your variables/references properly.
Maybe your problem is Flash bug too.
In my FLA there was a layer with one empty keyframe. If I puted a vector graphics on it, the error was gone. If there was one or multiple MovieClips and there was no vector graphic - the error was there again.
Then I made a new layer and copy pasted all the objects from damaged layer to new and deleted the damaged layer. It solved the problem.
NOTE: Don't copy the keyframes. Only copy the contents.
Now my project is much more complicated and sadly the error came back again.
Test movie frequently and if the error comes back, check the last keyframes and layers you created.

External SWF Loading problem

I have an SWF loading in an SWF containing a papervision scene.
I've done it before yet problem is, I get an error - I'm not sure what the issue really is.
private function downloadSWF(url:String):void
{
trace(url);
var urlRequest:URLRequest = new URLRequest(url);
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loaderProgressEventHandler);
loader.load(urlRequest);
}
private function loaderProgressEventHandler(ev:ProgressEvent):void
{
loader.preloaderCircle.percent = ev.bytesLoaded / ev.bytesTotal;
}
When the application runs the code - I get the error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at com.dehash.pv3d.examples.physics::WowDemo()
Why am I getting this if the loading hasn't even complete yet?
Thanks in advance guys.
Edit: Try a blank child swf, see if the other one was trying access something in the parent. – Jorge
I did this, it seems, even with a simple SWF with a mouse click listener causes the Error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at simple_fla::MainTimeline/frame1()
My code for that is:
import flash.events.MouseEvent;
this.stage.addEventListener(MouseEvent.CLICK, onClick);
function onClick(ev:MouseEvent):void
{
trace("MouseClick");
}
Am I missing something blatantly obvious??
The problem is that the loaded swf starts running without it being added to the stage. So stage is null, resulting in that error.
The second example with the addedToStageEventHandler works because there stage is only referenced after the object was added to the stage, so stage is not null anymore.
A possible solution for the first error is adding the loader to the stage. That way, when the swf is loaded and starts, it already has a stage reference.
It won't even load if there's an error. You're accessing an unreferenced object on the WowDemo() class...did you instantiate correctly the class?
this seems to work inside my child SWF:
this.addEventListener(Event.ADDED_TO_STAGE, addedToStageEventHandler);
function onClick(ev:MouseEvent):void
{
trace("MouseClick");
var event:Event = new Event("END", true, false);
this.dispatchEvent(event);
}
function addedToStageEventHandler(ev:Event):void
{
this.stage.addEventListener(MouseEvent.CLICK, onClick);
}
does anyone know Why?
