Question

So i have two Class’s Class A and Class B.

I have a function that i wish to use on Class A but my flash fla file is linked to Class B

So I have done the following:

Class A – the function

    public function Fb_Checks()
    {
        // constructor code
        load_top_bar();
    }

Class B – import

import ClassA;

then if i try to call the function in Class A from Class B:

Fb_Checks();

I get the following error:

Call to a possibly undefined method Fb_Checks.

Is there something more i should be doing to get this to work?

You need to get more info about the OOP. How it is working then it will be easier to understand concepts.

For now simple explanation: We have ClassA, ClassB and ClassC:

ClassA
{
    var value:ClassB;

    public function ClassA ()
    {
        // each variable needs to initialize unless it is the ClassC, see below
        // Only after that you will be able to reach the public properties
        // of the class.
        value = new ClassB();
        value.calculate();
    }
}

ClassB
{
    var value:Number;

    public function ClassB ()
    {

    }

    public function calculate():void
    {
        // these must be statis
        ClassC.sum(150, 450);
    }
}

ClassC
{
    // if the function is static, then you can call it without initializing
    // the class
    static public function sum(value1:Number, value2:Number):Number
    {
        return value1 + value2;
    }
}
