Augmented Reality

[Fifra]

Trying to do some augmented reality in flash with as3. One however the following code is giving me trouble.
Error 1120 Access of undefined property Keyboard
Error 1180 Call to a possibly undefined method addFrameScript.

ps" this is my first time working with flash. Also, I'm am using papervision 3D.

You do not need all those classes.
While importing unused classes does not produce overhead, it reduces the readability a lot.
For instance, you are missing one class that you are actually using.

stage.addEventListener(KeyboardEvent.KEY_DOWN, myKeyDown);

no need to add this every frame.

Error 1180 Call to a possibly undefined method addFrameScript.

this method is not used in the code that you posted.

If you post errors, post the line on which they occur.

Yes thank you i was missing a particular import. I am new to as3. now the program does not give me errors however all i get is a grey screen.... hmmm. I'll see what i can do about with that
