Global Variables and GlowFilters is not working

Question

Good day all,

I m new to actionscript3 , and I cant solve few problems on my code. The first problem is glowfilter is not run. According to my research glowfilter 's alpha is set like that but , when ı click true answer it do not response. But the ı try algorithm ıt enter the right case. The second problem is I want to define write answer as global but when ı changed the rightAnswer in a function it is not change,how can ı over this problem ? I think defining global variable in actionscript is different from c .

Thank you for your help and sorry for my bad english!

rightAnswer is set to 0 in your code so no matter what you click on it will never evaluate to true — The_asMan, Sep 11 '13 at 14:55
even if ı didnt set to 0 , ıt is automatically set to 0. but I changed my code as a when every new question comes from an array , ı want to assign new value of rightAnswer to global variable rightAnswer, but even in the basic when ı call the question preparing function ı need to change value of public var rightAnswer:int . — user2769027, Sep 11 '13 at 15:42

You issue is with variable scope, it is not doing what you think it is doing.
When you use keyword "var" you re creating a new variable in the current scope.
In this case you are trying to assign 2 to the class level variable "rightAnswer" when in fact you are creating a new variable called "rightAnswer" scoped to function level.

    public function application1_creationCompleteHandler(event:FlexEvent):void
    {
        // TODO Auto-generated method stub
        soru.text = " En büyük kim ?";
        answer1.label = "Galasaray";
        answer2.label = "Bursaspor";
        answer3.label = "Beşiktaş";
        answer4.label = "Fenerbahçe";
        var rightAnswer:int = 2; // <<<<--- right here is your problem
        trace(" rightAnswer fonkideki " + rightAnswer); 
    }

So instead do this.

    public function application1_creationCompleteHandler(event:FlexEvent):void
    {
        // TODO Auto-generated method stub
        soru.text = " En büyük kim ?";
        answer1.label = "Galasaray";
        answer2.label = "Bursaspor";
        answer3.label = "Beşiktaş";
        answer4.label = "Fenerbahçe";
        var rightAnswer:int = 12345678; // <<<<--- right here is your problem
        this.rightAnswer = 2; // <<<<--- here is your correction
        trace(" rightAnswer class level" + this.rightAnswer);
        trace(" rightAnswer function level" + rightAnswer);// << -- this can only be accessed inside of the current function


    }
