RE: [ft] Orbits in Vector

Huh?

OK,let me get this straight... so the Gravity is strong up close...not
so
strong a little further out, and then strong again even further out???

I *assume* you mean '...and if you end up 12-18" away you get pulled in
1".'
1", right? Not 3"? ;-)

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
