Extending InteractiveObject

[MichaelxxOA]

So I'm in the Flash 9 Alpha...

With the new VM there is no need to use MovieClips unless that element has a timeline of it's own.. and there's no need to use Sprite/DisplayObjectContainer unless you're element will contain children of it's own, and so on and so forth.

So I decide in my Ball Throwing example that my ball could be an InteractiveObject just fine, so I extend it and test it, and due to my good fortune I get an Error

ArgumentError: Error #2012: Ball class cannot be instantiated.
	at com::Experiment$iinit()

So.. I go to Flex Builder and test my code, and it works fine.

So I guess this is just a heads up for you guys to know that this is just an Alpha bug and will be resolved, I sent an email to Adobe.

Take care.

The InteractiveObject class is the abstract base class for all display objects with which you can interact: mouse, keyboard, and focus.

You cannot instantiate the InteractiveObject class directly. A call to new InteractiveObject() throws an ArgumentError exception.

This aint a bug bud.

I'm not instantiating it, I'm extending it.

You successfully instantiated a subclass of InteractiveObject in Flex Builder? I don't think you're allowed to (having to do with extending abstract classes directly)

[MichaelxxOA]

Yes I can, and no I can't.. I just downloaded the final Flex 2 (was using Beta 3)

This all actually came from a conversation I had with Danny Patterson today who was telling me that in these cases I'd want to extend InteractiveObject directly.

I'll talk to him some more and see what I can figure out...

Take care, thanks.

I'll ask around here too.

Did you implement a constructor for your Ball class?

Yes I did implement a constructor...

I just realized that I shouldn't be using InteractiveObject anyway, because I'm using the Graphic of the ball object, and Graphic isn't defined in the inheritance chain until Sprite, at the same time even on the most simplified of classes I'm still getting an error when extending InteractiveObject.

I'm not instantiating it, I'm extending it.

in extending it, and then creating an instance of it, you are instantiating it.

I pretty sure you cannot just extend it like you are trying.
