ActionScript 3.0 :: Loading Blank SWF With Document Class - Stage Is Null

Apr 22, 2009

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

That's the error message I get when it tries to play. What I have is an swf that loads another when its done, the new swf is blank but has a document class to an AS file. It seems the problem lies when a function is not properly being added to the stage.

The function is added like this..
Code:
package{
public class QuizApp extends Sprite{
public function QuizApp(){
createButtons();
private function createButtons() {
if (this.stage == null) {
trace("STAGE IS NULL!!!");
} var yPosition:Number;
addEventListener(Event.ADDED_TO_STAGE, addedToStage);
...

Stage Is Null In Document Class?

May 13, 2011

In my document class named Engine, the stage variable is for some reason null:

package game
{
import flash.display.MovieClip;

[Code]....

This was working fine up until now. I just recently added two dynamic text fields into a symbol, and all of a sudden the stage is null. I really don't see the connection.

ActionScript 3.0 :: Stage Is Null Within My Document Class?

Apr 2, 2011

I keep on getting "cannot access property of a null object" errors. With the debugger I pinpointed my issue at the line where I write stage.stageWidth.So somehow the stage is null. This is within my Document class which is linked with the .fla. The strange part is that I haven't had this problem until just recently.

Actionscript :: Targeting Sprites From A Method In The Document Class - Null Object Reference?

Feb 9, 2011

I am trying to code a flash app entirely in the document class. I am using GestureWorks with a touch screen. When a user essentially presses a button it calls a method that should hide a specific graphic but not the graphic they touched.

Essentially I need a way to refer to a graphic on the screen using a method besides 'e.target'.

I am receiving this error: Error #1009: Cannot access a property or method of a null object reference.

[Code]...

It can access photo1Sprite as 'e.target' when the button click happens on the photo1Sprite. The problem happens when to click one button (not photo1Sprite) and have it effect photo1Sprite. So I can make photo1Sprite react if my method is attached to it directly using 'e.target' but not if I am trying to call it from a method that was called from another element on the screen.

Actionscript 3 :: Access A Displayobject On Stage In A Class That Is Not A Document Class?

Mar 7, 2012

How to access a display object on the stage in a class which is not a document class?

I am looking for a solution that doesn't involve passing the stage as a parameter to the class.

One solution i always come across is using "TopLevel.as". Is it a good method because as far as I have heard using global variables is not recommended because it might cause some problems while working on big projects.

Flash :: Call Stage Objects From A Non Document Class?

Sep 1, 2010

I'm trying to manipulate (in this particular case add eventListeners) objects (in this case some MovieClips) on the stage from a class that isn't the document class.

1120: Access of undefined property trans.

Now I know that it's probably a scope thing and I probably can't access stage objects directly from a non document class (as I'm doing in the code below) but I can't figure out how to access them properly.

Anyway, here's the deal:

I've got 3 dynamic text fields (called "NL", "FR" and "EN") on my stage in a movieclip called "trans". I'm trying to add eventlisteners in a second class to make them do something when clicked on.

Here's my document class:

package {
import flash.display.MovieClip;
// Import custom classes.

Flash - Loading SWF Without Instantiating Document Class?

Sep 26, 2011

Is there a way I can load a swf file but not automatically instantiate it's DocumentClass? Instead I want to do something like the following:
protected function mainLoaded(e:Event = null):void {
trace('mainLoaded');
var main:* = this.mainLoad.createClassByName('Main');
trace(main);
}
Where mainLoad is an instance of CasaLib's SwfLoad and createClassByName is the equivalent to
loaderInfo.applicationDomain.getDefinition();
The thing is that when my swf finishes loading I can see it is created, because of some trace calls, although its obviously not added to the display list.
