Hey, I was wondering if they found a better way of allowing the use of variables outside of an on function. For example in the script below I can use the variable bounds inside the target.onEnterFrame function because it’s declared inside the constructer. However I can’t use m\_Bounds even though it’s declared in the class.

[AS] private var m\_mcTarget:MovieClip;  
private var m\_Bounds:BoundsData;

```
function MotionHandler(target:MovieClip, bounds:BoundsData)
{
    m_mcTarget = target;
    m_Bounds = bounds;
    
    m_mcTarget.onEnterFrame = function()
    {
        this._x = bounds.current.x;
        this._y = bounds.current.y;
    }
    
}[/AS]

```

I find it annoying and unorganized to redeclare variables from my own class just to use them in the onClick/onRelease/onEnterFrame etc.

If I were to move that onEnterFrame to a different function, I would have to provide a copy of the bounds var inside that function.

[AS] private var m\_mcTarget:MovieClip;  
private var m\_Bounds:BoundsData;

```
function MotionHandler(target:MovieClip, bounds:BoundsData)
{
    m_mcTarget = target;
    m_Bounds = bounds;
}

public function Initialize():Void
{
    var bounds:BoundsData = m_Bounds;
    
    m_mcTarget.onEnterFrame = function()
    {
        this._x = bounds.current.x;
        this._y = bounds.current.y;
    }
}[/AS]

```

In AS3.0 will they let us use class variables in on functions or are there any other methods?
