You could have something like
Code:
self.magneticStrength = 0.5;
local dist = SceneMan:ShortestDistance(self.Pos,self.target.Pos,true);
self.target.Vel = self.target.Vel + dist:SetMagnitude(self.magneticStrength^dist.Magnitude);

Since magnetic strength decreases exponentially over distance.

My bit of code was just a snippet. But yeah, PresetName check would do it.

Yeah, but you could condense it a bit, and optimize. (And change the actual variables to match up). And BTW, one (=) to set a value, two (==) to check.
Code:
   self.magneticStrength = 0.5;

   for particle in MovableMan.Particle do
      if particle.PresetName == self.PresetName then
         local dist = SceneMan:ShortestDistance(self.Pos,particle.Pos,true);
         if dist.Magnitude < 5 then
               particle.Vel = self.target.Vel + dist:SetMagnitude(self.magneticStrength^dist.Magnitude);
         end
      end
   end

Dump the "self.magneticStrength = 0.5" in function Create(), don't leave it in Update().

Can I see your complete script?

Change line 24 to this:
Code:
                if particle.PresetName ~= nil and particle.PresetName == self.PresetName then

Well THERE'S the problem. You're supposed to change all "self.target" to the pointer you're using for the particle silly ("particle").

That is correct.
