Spawn Height on this post proccesing effect

So what would i add to this to get a spawn height option?

[lua]CreateClientConVar(“pp_rain_particles”, “20”, true, false)
local rainning = CreateClientConVar(“pp_rain”, “0”, false, false)
local NT = 0

function Rain_Think()
if NT < CurTime() then
if rainning:GetBool() then
local e = EffectData()
e:SetMagnitude(tonumber(LocalPlayer():GetInfo(“pp_rain_particles”)))
util.Effect(“rain”, e)
end
NT = CurTime()+1
end
end
hook.Add(“Think”, “RainThink”, Rain_Think)

local function BuildControlPanel(CPanel)
CPanel:AddControl(“Header”, {Text = “Rain”, Description = “Settings:”})
CPanel:AddControl(“CheckBox”, {Label = “Rainning?”, Command = “pp_rain”})
CPanel:AddControl(“Slider”, {Label = “Number of rain particles:”, Command = “pp_rain_particles”, Type = “Int”, Min = “25”, Max = “2500”})
end

local function AddPostProcessMenu()
spawnmenu.AddToolMenuOption(“PostProcessing”, “Other”, “Rain”, “Rain”, “”, “”, BuildControlPanel,{SwitchConVar = “pp_rain”})
end
hook.Add(“PopulateToolMenu”, “AddPostProcessMenu_Rain”, AddPostProcessMenu)[/lua]

[lua]e:SetOrigin( LocalPlayer():GetUp() * youheighthere )[/lua]
