Re: [ft] Orbits in Vector

G'day Laserlight,

We use a simple system whereby the gravilty well of the planet is based
on 
its diameter. For instance, say you've got a planet that's 6" then if
you 
end up within 6" of the planet's edge then you get pulled in 3", if you
end 
up 6 - 12" away then you get pulled in 2" and if you end up 12 - 18"
away 
you get pulled in 3". Works well and I've used it quite a few times to 
swing me around a planet... its a bugger when you lose your engines mid 
sling though! ;)

Cheers

Beth
