emitter failure

[Joe]

I have this emitter giving a pulse at a normalised vector of itself but it won't fire. can anyone give me advice on what is wrong with this script?

 

Thank you

 

 

local n = b:Normalize() * 4

local ect,e

if e == nil then

 

ect = 10

e = Emitter:Create(5)

e:SetPosition(n,true)

e:SetInterval(1)

e:SetDuration(5)

e:SetEmissionShape(1)

e:SetEmissionVolume(0, 0, 0)

e:ClearAlphaControlPoints()

e:ClearScaleControlPoints()

e:AddScaleControlPoint(0, 4)

e:AddScaleControlPoint(1, 6)

e:SetParticleColor(0.1, 0, 0, 1, 0)

e:SetParticleColor(0.95, 0, 0, 1, 1)

e:SetVelocity(0, 0, 0, 0) --e:SetVelocity(n.x, n.y, n.z, 0)

e:SetVelocity(0, 0, 0, 1)

e:SetAcceleration(n.x,n.y,n.z)

e:SetLoopMode(false)

 

end

 

if e ~= nil then

ect = ect - 1

if ect == 0 then

 

e:Release()

 

end

it was SetDuration, not in milliseconds
