[killerrichard]

Hello all !

I have my code who isn't working but the code is well coded
what its the problem ?

Pos and NPC are ok
Material Exist
Folder of effect exist
but no effect showing on game but all other effect i have work
why this one not ?

part of code shared of NPC
[lua]
local edata = EffectData()

edata:SetOrigin( self:EyePos() + (self:GetUp() * 24))
edata:SetEntity( self )

util.Effect("selleffect", edata, true, true )
[/lua]

whole code from init.lua from folder (selleffect) in entities/effects/
[lua]

EFFECT.Mat = Material("gaming52/light/sell")

function EFFECT:Init( data )
self.Pos = data:GetOrigin()
self.NPC = data:GetEntity()
end

function EFFECT:Think( )
return true
end

function EFFECT:Render( )

render.SetMaterial( self.Mat )

local sin = math.abs( math.sin( CurTime()*1.5 ) )
local eyevec = EyeVector() * -1
eyevec.z = 0
local color_effect = Color( 255, 255, 255 )

render.DrawQuadEasy(
self.Pos,
eyevec,
64 + sin * 4,
32 + sin * 4,
color_effect,
180
)

end
[/lua]
