This is, hopefully, not a very complex script that I'm asking for. I would like a script that creates a trail of MOSParticles on an object very often, so that the trail isn't all separated like it would be if i tried to make this with INI code.

Code:
function Create(self)
self.parspacing = 10; -- spacing betwen trail particles
self.lastpos = self.Pos;
end

function Update(self)
self.distcheck = SceneMan:ShortestDistance(self.lastpos,self.Pos,true)
if self.distcheck.Magnitude >= self.parspacing then
self.repnum = math.floor(self.distcheck.Magnitude/self.parspacing)
for i = 1, self.repnum do
self.tpar = CreateMOSParticle("trail particle");
self.tpar.Pos = self.lastpos + self.distcheck:SetMagnitude(i*self.parspacing);
MovableMan:AddParticle(self.tpar);
self.tpar = nil;
end
end
self.lastpos = self.Pos;
end

Did that on a DSI, so no tabz 4 u.

Thank-you very much, i've tried tabbing it on my own, and i want to know if this is correct:

Code:
function Create(self)
self.parspacing = 6; -- spacing betwen trail particles
self.lastpos = self.Pos;
end

function Update(self)
self.distcheck = SceneMan:ShortestDistance(self.lastpos,self.Pos,true)
   if self.distcheck.Magnitude >= self.parspacing then
   self.repnum = math.floor(self.distcheck.Magnitude/self.parspacing)
      for i = 1, self.repnum do
      self.tpar = CreateMOSParticle("trail particle");
      self.tpar.Pos = self.lastpos + self.distcheck:SetMagnitude(i*self.parspacing);
      MovableMan:AddParticle(self.tpar);
      self.tpar = nil;
      end
   end
self.lastpos = self.Pos;
end

tabbing doesn't matter; lua ignores whitespace

Then i'm confused; why doesn't this work?

Probably because I typed something wrong. Open up the console after creating/using whatever had the script and check for errors.

Or you might've forgoten to change the particle PresetName in the script...

the console doesn't display any errors, in fact i changed the ScriptPath to a non-existent script and it still didn't display an error. what's going on here?

but yes, to test it i changed the PresetName to Small Smoke Ball 1

Try that.
