It's fairly easy to use. Mostly it's a matter of path finding and response to stimulus. If you're expecting anything beyond those, such as being able to get an AI to take cover when you throw grenades or be a formidable oponent in am RTS, then it'll help, but you're going to have to do a lot more work.
All this does is cut out the need to develop things like cone of vision, responding to sounds, and navigating a level.
Nothing I say is intended to be rude. My autism means that I do not know what is rude and what isn't rude. I apologize if I seem rude. It is not my intention.
