Perhaps you got me wrong, or I didn't explain good enough. In order
to have particles move at least a little their original direction, I add
the inertia-vector using a percentage of 50%. This means, that
the actual direction is deriven to 50% by the original direction, and
to 50 percent by the inertia-vector. Using a 100%-Inertia-Effect
would mean they have no own speed and direction whatsoever.

As for the air-resistance, that should be taken into account for when
using the global-wind-settings. It's not that easily described algorithmically

when using a non I/O system, keeping track of speed and headings
isn't really trivial in such a case (using I/O, you can look at the speed and
simply scale it down, if you want to, for non I/O, I'd had to calculate
and remember when I did that at all times.)

But it looks more realistic, I agree on that.

Thanks for you help!
