spawn towards nearest particle possible?

[joe_coke]

Ok so i'm now trying to get a fake growth setup to work.  I figured i could birth 1 particle then spawn multiple offset a distance using the spread operator.  After that i spawned at a rate per sec and tested against a binding absolute distance to keep the particles apart and end up with a nice even (not symmetrical) cover of the surface.  Problem is the spawned particles jump position every frame, so i added a test against event time to freeze after they had found a valid position. alas, still plenty of position jumping.
