Using same function across frames

1

I am making my first site in AS3 and am working on the onResize event. My problem is, my preloader frame has an onResize event and my main frame has an onResize event.

preload:


stage.addEventListener(Event.RESIZE, arrangeStage);
function arrangeStage(e:Event):void
{
    lbar.x = 0;
    var middleY = stage.stageHeight/2;
    TweenLite.to(lpc,1.5,{y:middleY,ease:Exponential.easeOut});
    TweenLite.to(lbar,1.5,{y:middleY,ease:Exponential.easeOut});
}

main frame:
it has nothing right now, but when it gets to this frame I get this error when I resize:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at sitetemplate_fla::MainTimeline/arrangeStage()

I read one of senoculars post (#352) on this page http://www.kirupa.com/forum/showthread.php?p=2112820

and it says to define a function like so:
ActionScript Code:
[LEFT][COLOR=#808080]// Frame 1[/COLOR]
[COLOR=#808080]// declare class variable[/COLOR]
[COLOR=#000000]var[/COLOR] myFunction:[COLOR=#000000]Function[/COLOR];

[COLOR=#808080]// first definiton[/COLOR]
myFunction = [COLOR=#000000]function[/COLOR]COLOR=#000000[/COLOR]:[COLOR=#0000FF]void[/COLOR] [COLOR=#000000]{[/COLOR]
[COLOR=#808080]// code…[/COLOR]
[COLOR=#000000]}[/COLOR]

[COLOR=#808080]// Frame 2[/COLOR]
[COLOR=#808080]// second definition[/COLOR]
myFunction = [COLOR=#000000]function[/COLOR]COLOR=#000000[/COLOR]:[COLOR=#0000FF]void[/COLOR] [COLOR=#000000]{[/COLOR]
[COLOR=#808080]// different code…[/COLOR]
[COLOR=#000000]}[/COLOR]
[/LEFT]

well I tried it exactly how it says there and I get these errors:

TypeError: Error #2007: Parameter listener must be non-null.
at flash.events::EventDispatcher/addEventListener()
at flash.display::Stage/addEventListener()
at sitetemplate_fla::MainTimeline/sitetemplate_fla::frame1()

and it looks like this:
ActionScript Code:
[LEFT][COLOR=#000000]var[/COLOR] arrangeStage:[COLOR=#000000]Function[/COLOR];

arrangeStage = [COLOR=#000000]function[/COLOR]COLOR=#000000[/COLOR]:[COLOR=#0000FF]void[/COLOR]
[COLOR=#000000]{[/COLOR]
lbar.[COLOR=#000080]x[/COLOR] = [COLOR=#000080]0[/COLOR];
[COLOR=#000000]var[/COLOR] middleY = [COLOR=#0000FF]stage[/COLOR].[COLOR=#000080]stageHeight[/COLOR]/[COLOR=#000080]2[/COLOR];
TweenLite.[COLOR=#000080]to[/COLOR]COLOR=#000000[/COLOR];
TweenLite.[COLOR=#000080]to[/COLOR]COLOR=#000000[/COLOR];
[COLOR=#000000]}[/COLOR]
[/LEFT]

any idea??

if you want you’re original approach to work, you’ll need to remove your old resize before exiting the preloader frame, then add a new resize after that.

And really, thats probably the best way to do it. You could use an anonymous function via functionName = function()… but by redefining that, you’re not changing the listener if the first variation was added in frame 1. The best you could do then is create a listener that calls that function, then you could redefine it and the listener would always reference the value as you set it (different function values for different frames)
