For now i only see that way of changeing body parts:
1)GoToAndPlay() - wjen it enters frame it changes on some value
2)GotoAndStop() - the same / And to change again reload the model to another frame and back
3)Make it derectly from main layer HeyYouPartNumber1.PartInPart1.PartInPartInpart1(GotoAndStop(1));
Or may be there are another ways - that i do not know ?
I get interesting idea about it (Using recurtion and auto understanding of what to load).
Can you tell me what other ways are i try to understand what is the best way
