Flash AS3: How can I get functions to exit the game loop?

Question

I am working on a Flash project with multiple scenes. I use the function:

function gameloop(e:Event)  {

to add my functions in to one scene, but when switching the scene I am rained on with errors because the objects used in the other scene are no longer on screen. Is there an opposite to the code I pasted here to take functions out of the game loop for my other scenes?

Answer 1

function gameloop(e:Event)  {
    if(currentFrame != 2){
        return;
    }
}

Check currentFrame in the loop.
