Thank you for the awesome particle engine. Just learning this thing, and ran into an issue...

I want to create a certain effect based on the 'energy' of the particle, where energy is a number of its neighbors. Is there some easy way of determining it, or should I implement one myself?

TIA and cheers :) ]]> http://flintparticles.org/forum/comments.php?DiscussionID=248&Focus=897#Comment_897 http://flintparticles.org/forum/comments.php?DiscussionID=248&Focus=897#Comment_897 Wed, 12 Aug 2009 08:12:35 +0100 Richard
You'll probably need a custom action for this. Some of the existing actions (like ApproachNeighbours) relate to the number and location of neighbours, but it doesn't sound like you want any of the specific actions already implemented in the library. You might find the source code for ApproachNeighbours useful in implementing your own solution.

I made my own action based on ApproachNeighbours, exactly how you said, though if I wanted to optimize it better, especially in case of a large number of particles, I think the best solution would be to implement a grid-based solution, like Grant did in his ProximityManager.
