Stjohn Posted April 17, 2008 Share Posted April 17, 2008 The scenario is this: I've got a particle system which is attracted to a specific set of goal points. Goal points are made with SOPs and forces are assigned there. They also move relative to the particle system, so the particles have to chase the goals a little bit, then settle in. I'm using Single Point Per Particle on the attractor. the problem: The particles always overshoot the goal points, never quite catching them. I've tried lots of stuff, including messing with the charge, 'stop at attractor' and just suppressing velocity when they get close enough. Still no joy. I've also tried a VOP POP that measures the distance between particle and attractor point and decreased velocity accordingly. The results were... Interesting. What's the foolproof, mature, and dignified way to make particles go toward goal points and stick to them? Quote Link to comment Share on other sites More sharing options...

The results were... Interesting. Instead of using the distance between the particle and attractor to decrease the velocity, you could try and put that into the scale parameter on the attractor?

eetu Posted April 17, 2008 Share Posted April 17, 2008 Perhaps try adding a drag attribute, it should calm things down a bit. eetu. Quote Link to comment Share on other sites More sharing options...
TheAdmira1 Posted April 17, 2008 Share Posted April 17, 2008 how strong is ur original velocity? i had a similiar problem, then realized my inherent velocity was set at bout 13... way too strong for the distance they were traveling... theyd birth and move rather quickly, then kinda slow down past th attractor, but then they continue on past... once i turned down the velocity and added a drag like eetu said, all was well with my particles...

3__ Posted April 18, 2008 Share Posted April 18, 2008 (edited) ok this is pretty dodgy but try setting the goal position in the particle colours then blend between particle pos and particle colour. using whatever age or distance function. particlegoal.zip Edited April 18, 2008 by cpb Quote Link to comment Share on other sites More sharing options...
GallenWolf Posted April 18, 2008 Share Posted April 18, 2008 Did you guys try upping the oversampling at the pop node level? I find that turning it up does help.... hate turning it up though. GW Quote Link to comment Share on other sites More sharing options...
