Actionscript 3: Create dictionary inside class?

Question

I'm trying to transform my actionscript 3 code from the timeline, which I previously used, to packages.

I need to define some dictionaries in the beginning of the code.

But when running the following code inside my class, actionscript returns an error.

public var S_USA:Dictionary = new Dictionary();
    S_USA["x"] = -299;
    S_USA["y"] = -114;
    S_USA["bynavn"] = "New York";

This is the error: "1120: Access of undefined property S_USA.

Answer 1

Are you setting this data inside Constructor or function?

EDIT:

Hm, where to start...

1) You know that the trick with static is not gonna work if you'll create more than 1 instance of class? In this case if you have only 1 Main class it's gonna work, but omg... Imho it's not nice to store data in static vars...

2) If you already declared:

public var bynavntxt:TextField;
public var intervall:TextField;

later just do

bynavntxt = new TextField()  ;
intervall = new TextField()  ;

no need for type in there.

3) Later in Main you have something like:

var mcOut = new OutCursorClip();
this.addChild(mcOut);

var mcIn = new InCursorClip();
this.addChild(mcIn);

Why are you declaring new variables with same name but without Type?

Waaaaaay up you have:

public var mcIn:MovieClip;
public var mcOut:MovieClip;

so those variables are already declared. By declaring them once again you are creating local ones. Beware!! The ones from the top would be null after that.

Answer 2

1) Fill the dictionary inside the Constructor (I seen by comments you have done this already).

2) you have already assigned type to bynavntxt with public var bynavntxt:TextField; you should not be doing it again with bynavntxt:TextField = new TextField(); just bynavntxt= new TextField(); will do.

This is the same with all other variables on similar type.

3) Make sure this class is going to be your "Document Class"/"Compiled Class" otherwise you will not have access to the 'stage' variable yet. To make sure you will have access to the stage variable you can always do:

/* Inside Constructor */
addEventListener(Event.ADDED_TO_STAGE, _onAddedToStage);

/* Outside Constructor */
private function _onAddedToStage(e:Event):void
{
    removeEventListener(Event.ADDED_TO_STAGE, _onAddedToStage);
    stage.addEventListener(KeyboardEvent.KEY_DOWN, keyHandler);
    stage.addEventListener(KeyboardEvent.KEY_UP, keyHandler);
}

Again, if this is going to be the compiled class, this can be skipped.
