please see atched patch …
i try to simulate a fish swarm, so far so good.
but now i would like to avoid that the “fishes” swim in certain areas (red ones).
tried it already with attractor, but then you get always strange movments aka not so fish like.
i don’t know if this is usable but it is an idea.
well, different settings leading to very funny behaviour.
for sure you have to use very small strength settings.
my family doesn’t allow me the fine tuning right now…
but i have now kind of ugly workaround solution, see new patch.
trick here to combine all “no go areas” with all particle positions and scale them out if they are in a no go area … okay not really cool, but visually a more or less solution :)
