Question

So i have this function

capture_mc.buttonMode = true;
capture_mc.addEventListener(MouseEvent.CLICK,captureImage);

function captureImage(e:MouseEvent):void { 
//lalalala

}

I want to call this function every 2 seconds (after mouse click event happens).
I tried using setInterval

setInterval(captureImage,2000,e:MouseEvent);

but it leads to following error

1084: Syntax error: expecting rightparen before colon.

What’s wrong ?
And ya, i am new to AS.

First, since this is AS3 you should be using Timer and TimerEvent. I’ll show you how in the example.

Now you’ll need to separate your functions:

edit: I’ve updated this to be safer based on @(Juan Pablo Califano) suggestions. I would keep the same timer for ever if the amount of time isn’t going to change.

// first param is milliseconds, second is repeat count (with 0 for infinite)
private var captureTimer:Timer = new Timer(2000, 0);
captureTimer.addEventListener(TimerEvent.TIMER, handleInterval);

function handleClick(event:MouseEvent):void
{
    // call here if you want the first capture to happen immediately
    captureImage();

    // start it
    captureTimer.start();
}

function handleInterval(event:TimerEvent):void
{
    captureImage();
}

function captureImage():void
{
    // lalalala
}

You can also stop the timer with captureTimer.stop() whenever you want.
