Question

Currently I have an Array that is having 9 buttons pushed to it. This is called BAR.as:

public static var buttonArray: Array = new Array()

for(var i:int = 0; i<9; i++){
            barButton = new button
            buttonArray.push(barButton)
            buttonArray[i].name = button+(String[i])
            buttonArray[i].x = 15+(i*buttonArray[i].width)
            addChild(buttonArray[i])
        }

Within the class for my button I have specified an enableButton function, this is called ACTIONBARBUTTON.as:

public static function enableButton(shortcut:int):void{
        //instance.refreshThis(shortcut, true)
        trace("test")
    }

What I am trying to do is have a function that I can call to enable/disable these buttons (but not just simply “.enable”/”.disable”) on demand, as the content within them needs to change often. My way to do this was going to be through BAR.as:

public static function updateWeapons(level: int):void{
        buttonArray[level-1].enableButton(level)
    }

However, this returns the following error:

ReferenceError: Error #1069: Property enableButton not found on src.actionbar.button and there is no default value.
at src.actionbar::bar$/updateWeapons()

Just running button.enableButton(1) works fine.

You can’t call a static member function on an instance of a class.

That’s why this :

buttonArray[level-1].enableButton(level)

Doesn’t work. Make the enableButton function non static and it should work.

button.enableButton(1)

Works fine because you are using the class name “button” to invoke the function.
