I implemented your suggestion. Sort of helps, but needs to be a bit differently implemented, of the flock whacks out. What works best for a flock motion is is FN MassLogic is called before the BirdThink loop. But getting the mass to flow around is still a problem, so a logic problem remains perhaps. I would almost think that a spline based move around of gMassX and gMassY would make the flock follow better, though I gather that it is supposed to be "self flowing" based on the boids themselves? Anyway, thanks for the comments. Robert
