[Visualpython-users] Right, so I made this dinky spaceship...

[Jeremy S. <rez...@ma...>]

Hi again. I'm very confused by the methods you can use to rotate an  
object, specifically a frame.

I made this model spaceship that I want to animate, such that the  
ship is always pointed in the direction that it's moving. The objects  
that make up the ship are grouped together in a frame, so that  
repositioning and rotating the model is a simpler process. The idea  
is to derive all the necessary information from one vector, called  
"dndt", that represents the velocity of the ship. That way, if I want  
to edit the path of the ship, the code that rotates the ship won't  
break. I've fiddled with the "axis" property of the frame object, and  
have just gotten really confused.

My program is a big mess, so I made a smaller example file, which is  
at http://homepage.mac.com/rezmason/spaceship.py . It's very basic,  
and you can use it however you wish.

Thanks,
