Question

At the moment I have a class that requires information from another class, but which class has to be determined at runtime based on other variables.

Effectively, I need my class BUTTON.as to be able to access GUN(1-9).as, without already knowing what number it will be.

The code that I assumed would work is this:

public function enableButton(shortcut:int):void{
        trace(ID)
        dtf_ammo.text = gun[ID].ammo
        refreshThis(shortcut, true)
        this.alpha = 1
        isActive = true
    }

ID is the number of the class (in this case, gun1).

The following does work:

public function enableButton(shortcut:int):void{
        trace(ID)
        dtf_ammo.text = gun1.ammo
        refreshThis(shortcut, true)
        this.alpha = 1
        isActive = true
    }

However, as there are 9 guns and only 1 class for the button I need to be able to use this ID variable to access functions within.

Is this possible, and if not is there a way to do what I’m trying to do here?

In order to access static properties of a class whose name is only known at runtime, you can use the following code.

getDefinitionByName("gun" + i).ammo

getDefinitionByName returns the Class object representing the class named by the String passed in. That Class object contains references to all of the static properties of the class.
