I'd like to make an effect that is similar to moths hovering around a light. The moths need to stay alive, so we can't generate and eliminate them. We need to have a lot of particles on screen, ...

We need to have a lot of particles on screen, probably 40+ lanterns, each with up to 40 particles around them

An acceptable approximation would be an elastic bounding box.

The particles will be on screen for a long time, so a gravity well that they would get sucked into would be a problem.]]> http://flintparticles.org/forum/comments.php?DiscussionID=538&Focus=1970#Comment_1970 2012-10-29T07:46:34+00:00 2013-08-21T00:05:08+01:00 Richard http://flintparticles.org/forum/account.php?u=1

How about a gravity well at the centre of a collision zone, perhaps with a disc zone, so they are attracted towards the gravity well but bounce off the collision zone before they fall into the well.
