If MovieClip exists

[friendlygiraffe]

Quite a simple question this one. I'm trying to prevent code being called on a DisplayObject if it doesn't exit.
This throws up an error

if (mc)
{
	trace(mc);
}

Throws up the following error

1120: Access of undefined property mc.

I've tried if(mc.stage), if (contains(mc)) and if (this.getChildByName("mc")) and none of them seem to work

Using Flash PLayer 9 in CS6

Thanks

Hi,

You at least need to declare mc if it is not already on the stage, or it will throw an error like the one you have.

var mc:MovieClip;

if (mc)
{
    trace(mc);
}
else
{
    trace("mc not on stage");
}

That worked, thanks

Strange, I don't remember this being an issue before. Perhaps I was thinking in AS2
