Using Avatar.Person

[VAmanda]

I have a couple of questions about using the Avatar.Person class. First, is there some way to pause the avatar's actions? More specifically, I have an avatar giving a speech using the following code:

speech = avatar.loadSpeech('speech.wav')
avatar.addIntentional(speech)
avatar.go()

I want to be able to press a key and pause the speech. If I call avatar.stop(), the animations stop, but the audio of the speech continues. Is there a way for me to pause this as well?

Also, I'm a bit confused on how to change the avatar's head/body using the Person class. I assume I'm supposed to use the replaceHead() and bodyType() methods, but I'm not sure how the number argument corresponds to the head or body that I actually want to use.

Thanks.
