Question

I fixed this error before where the source of the problem was that ‘stage’ was inaccessible from where I was putting the code (not in root). I deleted it and it ran fine, but the Event listeners that they were attatched to did not work anymore. I need these event listeners but when I try to put ‘stage.’ back infront it wont work. help?

This is what I had when it worked (when this file was still the root):

        stage.addEventListener(KeyboardEvent.KEY_DOWN, keypressed);
        stage.addEventListener(KeyboardEvent.KEY_UP, keyreleased);

Now my code is this, and it runs, just without the event listeners working:

        addEventListener(KeyboardEvent.KEY_DOWN, keypressed);
        addEventListener(KeyboardEvent.KEY_UP, keyreleased);

The stage property is null until the element is added to the stage. So you should first listen to the event Event.ADDED_TO_STAGE, and when you receive it, you can add your other event listeners:

addEventListener(Event.ADDED_TO_STAGE, addedToStage);

function addedTostage():void
{
    removeEventListener(Event.ADDED_TO_STAGE, addedToStage);
    stage.addEventListener(KeyboardEvent.KEY_DOWN, keypressed);
    stage.addEventListener(KeyboardEvent.KEY_UP, keyreleased);
}
