I'm having this problem: I have an external fla (Dawn.as) and I want to instantiate the class from the external file into the main swf timeline, but when I try doing that I get an error:
ActionScript Code:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

The main class shown below is showing a blank screen and is NOT navigating to [URL].
package {
import flash.display.Sprite;
import flash.net.navigateToURL;
import flash.net.URLRequest;
import flash.net.URLVariables;
public class NavigateToURL extends Sprite {
public function NavigateToURL() {
var url:String = "[URL]";
var request:URLRequest = new URLRequest(url);
navigateToURL(request); }}}
If I only instantiate a class once should I make its vars static? I understand how this is of benefit if I make multiple classes, clearly you use less memory as it creates a reference to the same place for each class. Are there any other benefits for creating static vars or functions ?
For example I have my class 'MainMenu' which I create once (might even be my document class). In it I create a
Code:
private var someHolderForStuff:Sprite = new Sprite();
Should I rather create
Code:
private static var someHolderForStuff:Sprite = new Sprite();
I have this main (document class) in a Flash project:
package {
import flash.display.MovieClip;
import flash.events.Event;
[Code]....
Now: if I pass a reference (ref) of the main class to Other and I add clippo as you can see in the first case, I can reference the movieclip clippo from the main (getChildAt(0) is "clippo" from the main). But, is there any way to use the second method (no ref) and do the same from the main class? I can see clippo onstage when Other creates it but I can't understand where clippo "lives" into the DisplayList.
I've got a simple program that consist of a document class and a buttonTemplate constructor class. I need to call a function called updateText that should be in the document class, when someone clicks on a button. So that after each button is clicked, it updates some text in my document class. My event listeners for the buttons are in the buttonTemplate class. My question is, how do you call a function in the document class from a constructor class? Here is my simplified code below
DOCUMENT CLASS
Code:
package {
import flash.display.MovieClip;
import flash.text.TextField;

I have this very simple ImageLoader class:[code]this doesn't work anymore, because of the presence of the stage movieclips "preloader" and "imageLoaderClip".Which is the most common way to make the things work? I thought to pass a reference to the ImageLoader class as a parameter (eg I pass the preloader and the movieclip that loads the images).
View 10 RepliesI'm trying to load a RSL library into a flash animation developed with Flash CS5 IDE, that extends a custom class and implements an interface. I have reduced the problem to the simplest setup and find that I can have my main class extend another class or implement an interface, but not do both at the same time if I want to load an RSL.I have a very simple class to extend:
import flash.display.Sprite;
public class MySprite extends Sprite

but if I want both I get the VerifyError: Error #1014 with MySprite not found and ReferenceError: Error #1065.

View 2 RepliesWe used to write our UnitTests with FlexUnit and we were just testing our model. Now we want to test the view too. Before i run my tests i create an instance of my view and my model to test the stuff. When i try to access the view i get a null pointer exception. If i add the view to the displaylist it somehow works - even if i remove it from the list right after adding.it looks something like this:
var myView: MyView = new myView();
//myView.initialize(); will throw error

I have an ancient project that has thousands of lines of AS2 code spread out in class files. I started to try to make an on-screen keyboard and I noticed an issue with FP8 and the Selection class. I need to use FP8 because it's a MDM Zinc extended project and Zinc does not allow me to export to FP9 or FP10 if I use AS2.0. Of course this issue doesn't happen in FP9 or FP10.I have a reproducible example here that's highly simplified and stripped down. It has 3 class files, a Main, ExampleKeyboard and ExampleOutput. Main just instantiates the other 2 classes. The keyboard is all of 3 buttons (again very simplified to stick to the point). The output just generates an input TextField. This issue seems to be isolated to using the Selection class when your project has other classes. For mine, the keyboard is in one class and the TextField is drawn in another. I did a single frame no-class example and this problem does not exist so it's specific to the Selection methods using FP8 when a project contains classes. URL...After you run it you MUST press the red button to Selection.setFocus() the input field. The other 2 gray buttons simply send the letters 'a' and 'b' to the input text field. In FP9 and FP10 this all works just fine. The Selection. getCaratIndex() reports the cursors proper position (which I set every time you press a button). In FP8 you will see that Selection.getCaratIndex() ALWAYS returns -1. Has anyone had these Selection class issues in a project that used multiple classes and FP8?
View 1 RepliesI am trying to use AMF PHP to pass variables to a flash file, thus far I cannot see anything wrong with my code, but I have very little experience with creating classes, so here it goes, here is my code,

Flash is looking for the flashMe class and the push method within that class, but I keep getting null variables in my flash file when I run it

When I set the following class as my document class it works (draws a rectangle) but when I don't set it as my document class and instead instantiate it using var myRec:simple_shape = new simple_shape(); in first frame of my timeline nothing happens no rectangle and no error either). why and how I can get it to work without setting it as my document class?

I asked yesterday how to call a function from an XML file, and I figured out how to make that work using the string-to-function call.so in my XML file I have <ITEM CALLBACK="ContactsList">View All</ITEM>, and my TextMenu class parses the XML file and creates my navigatable text menu instance. When enterMenu():String is called, it looks to see if the CALLBACK attribute has a value, and if so it returns it as a String.so..
var callbackFnc:String = textMenu.enterMenu();
if(callbackFnc != null)

I am loading one swf into another using the Loader class, but when the child swf finishes loading and is added to the display list, its Document Class is not instantiated. I have a few trace statements that should execute when the object is created, but nothing is happening when loaded into the parent SWF. When I compile the child SWF on its own, the Document Class runs as expected.
So I'm wondering... how do I associate a child SWF's Document Class with Loader.content?
[Code]...
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.
Here is the code:
ActionScript Code:
private class someFunction(classRef:Class):void
{
try
{
var instance:Object = new classRef();
[Code]...
Can I perform the check without instantiating?
I've got a confusing situation which wont seem to fix itself basically I have my main class, my iContent class (which will hold each page and have functions for all pages), and my individual pages.
The homepage is instantiated by calling the iContentClass.goHome method in the main document class. The home page contains a button to go on to the next page. This button references the goColourBrowserPage function within the iContentClass, which removes the child (being the home page) and attempts to add a child (colourBrowserPage).
For some reason this doesnt work! It doesnt seem to add the child and wont let me remove the child of the home page! I've been sitting here for 3 hours trying to work it but to no avail!

Is there a way to declare and instantiate an array using constants as indexes? I want to do something like:
public var arr:Array = new Array([ CONSTANT_A : "helloWorld", CONSTANT_B : "helloGoodbye" ]);
In php one could do:
$arr = array(CONSTANT_A => "foo", CONSTANT_B => "bar");
I'm making an app with pages set out as classes which extend the MovieClip class.
What I've got are back buttons and different pages which go to the same page, however... If I end up going out of a page and back into a page (specifically one with drawn squares and dynamic text boxes called from a web service), it seems to have kept all of the original information.
So far I've tried killing all of the children with a while loop targeting the index and also using weak event listeners - neither is working!
I have a MovieClip symbol that has 2 frames (for now). Depending on how it was initilialized, I want it to gotoAndStop at either frame or 2.Inside my class definition (Animal.as), I have written this as my constructor:
var type:String;
public function Animal(t:String = "") {
type = t;
[code]....
Let's say I have a defined ClassA. ClassB extends ClassA and there's a Movie Clip instance on the stage linked to ClassB. How would ClassC access the properties and methods of ClassB without extending ClassB or creating a new instance of ClassB? The way I'm currently doing it is by referencing the stage instance linked to ClassB and then using the dot syntax to access ClassB instance variables, and this works only if the the accessed variables are public or internal, depending on what package ClassC is part of. I would like to know if there's a better, cleaner way to accomplish this.

've tried calling constructor class from my main.fla, and it just doesn't work. The error when I try to instantiate the constructor is that it needs an argument... and since the class extends a Sprite.

...and after many days of being tested by this problem I have narrowed the location of my problem down to what can be seen up in the following.
Code:
for (a=0; a<4; a++){
for (b=0; b<4; b++){
var z:Number = ((a*4)+b);
_root.attachMovie("Light", ("L" + z), _root.getNextHightestDepth(), {_x:(a*45), _y:(b*45)});
}
}
For some reason, that loop will only attach one copy of my "Light" movie. I cannot seem to figure out why more are not added. I am putting that code on the first frame of my movie. There is nothing else in my project yet.
I have compared my array to [URL]
I have a symbol named picHolder. In symbol properties under linkage, I chose "Export for ActionScript" and "Export in frame 1" and gave it a class name of picHolder.Normally, to instantiate a new instance, I'd say:
Code:
var tempPic:picHolder = new picHolder();
and I'd go about my way.
