ah yes, I actually made them orbit the sun and it all worked and everything, but then you can't actually play the game since it's played like C&C 2d (imagine all the planets orbiting the sun in 2d space, and I have to tell Ship A to goto Planet B, which is whizzing around the sun in a 3D manner, on a 2D plane, let me just say, its a fricken nightmare! lol)
I'll update the link now - thanks for pointing that out.
