if ( !tr.Hit ) then return end
local SpawnPos = tr.HitPos + tr.HitNormal * 15

local ent = ents.Create( ClassName )
	ent:SetPos( SpawnPos )
	ent:SetParent( ply )
	ent:SetOwner( ply )
ent:Spawn()
ent:Activate()

return ent

end

function ENT:Think()
effect = EffectData()
effect:SetStart( self:GetPos() )
effect:SetOrigin( self:GetAngles():Forward() )
–util.Effect( “ToolTracer”, effect )

self:SetAngles( self.Owner:GetAngles() )
