How do I access Stage Class properties in Custom Class?
Class:

import Main;
import flash.events.*;

View 12 RepliesSo I have a movie clip associated with an external class in the linkage dialog. I put that movie clip on the stage. I have another external class that contains some code (not for the movie clip but for the stage). When I access the custom properties of the class in the actual flash file (not the external code) everything works fine.For example.myMovieClip.explodeTheCode = true;works in the main movie. However, it doesn't work in the external flash file when I have a reference to that movie clip.myRefToCustomMovieclip.explodeTheCode = true fails!It throws an error. In java, I'd just import the custom class the movie clip is linked to and then I can call all the extra custom methods on the movie clip in the external class I want. However, this does nothing. I still can't access any properties.So my question is, how do I access the custom features of a movie clip (that is linked to a custom class) from an external code file. It works in the movie, but not in the external source code.

In AS2 we can not add methods n properties to built-in classes in the way we do in AS1. Like we would -say- write the custom "isNatural" method on the "Math" class as follows : * The following code is valid in AS1 but not in AS2
[Code]...
As the "Math class" is static internally. We know why we can not add custom methods n properties to every class, as the way we do in AS1. Later I came up with senocular' s very nice tutorial on OOP in AS2. And now i know how we can do it in AS2 style in an efficient n organised way. But i have a problem with the following code. It should not work ! but it does... * Following code is valid for both in AS1 and AS2.

I want to have a custom class tempSelection with a Dictionary as a public accessable property of that class. If I use this code, the compiler tells me:
1046: Typ wurde nicht gefunden oder war keine Kompilierungszeit- onstante:Dictionary
Which translates to:

View 3 RepliesI have an object on my stage, called obj.I also have a class called "Physics" which contains a bunch of methods for physics, such as inertia, gravity, and bouncing off walls. In order to do some of these,I need access to the stage.stageWidth and stageHeight properties.My code is as follows:
public function wallBounce(obj)
{
this.stageRef = stageRef[code]...
This is supposed to check if the object's x value is greater than the stageWidth or less than 0. When I run this code it says:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I am a semi-newbie programmer who is completely self-taught and have no clue what is causing this. I spent a bit googling it, and I think it has something to do with scopes,.
If I have a swf that's being loaded into other peoples' swfs (which I have no control over) is there any way I can get properties from the stage (such as height, width, fullScreenHeight, etc.) or does this have to be exposed by the loading swf?

I'm new to as3 and I was trying to make my own slider for a while until I found the slider component. The slider component is so perfect for what I want to accomplish. But the size of the little graphics is ridiculous. If you click on the line that the slider knob is on top of the knob will snap to where you click. This is great but with only 3 pixels of height to click on it's pretty much useless. I tried going into the slider movie clip and altering the individual graphics but when I run the program the sizes are back to their teenie tiny size.

View 14 RepliesI am building your standard slideshow flash header for a web page.
There are three main parts:
The Slideshow class A controller class that is used as the projects Document Class Some linking timeline code.
The slideshow class has all the functionality, so I used the Document class to create a new instance of the slideshow and keep a property variable called slideshow that keeps a reference the Slideshow instance.

public class Header extends MovieClip

Despite me being able to call regular methods that are in the Doc Class from the timeline, I can not call properties without the following error, for example when i say slideshow.play():

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.
