Question

I’m new in ActionScript, and I’m trying to make my first application. I have a main class – subclass of Sprite. and another one class, wich should manage some evnts, like keyboard’s key pressing. Here is it’s initialisation:

private var controller:GameObjectController;
...
controller = new GameObjectController(this);

Here is controller:GameObjectController itself:

public class GameObjectController extends InteractiveObject
{
    var textField:TextField;

    public function GameObjectController(mainSprite: Sprite)
    {
    addEventListener(KeyboardEvent.KEY_DOWN, onKeyDown);

    textField = new TextField();
    textField.text = "Hello, World";
    mainSprite.addChild(textField);
    }

    private function onKeyDown(event: KeyboardEvent):void
    {
    textField.text = event.keyCode.toString();
    }

}

but when I’m trying to run this, I have an error:

ArgumentError: Error #2012: Class GameObjectController$ can not be
created.

What am I doing wrong?

From the docs: InteractiveObject

The InteractiveObject class itself does not include any APIs for
rendering content onscreen. To create a custom subclass of the
InteractiveObject class, extend one of the subclasses that do have
APIs for rendering content onscreen, such as the Sprite, SimpleButton,
TextField, or MovieClip classes.

So I would suggest trying to subclass Sprite instead and see if that fixes your problem.
