SWEP Help

[BarbecueCabba]

I'm making a Ninja RP job and I've got everything
set except for the ninja stars.. In my opinion that is
the most important part. I laid my eyes on this;
[url]http://www.garrysmod.org/downloads/?[/url]
a=view&id=48485
I would port it myself, but I'm not familiar with the
functions. If anyone would like to port this to the
current version of Garry's Mod, download it an go
ahead. Reply to this post if you have found a
working one
or ported it. Even though the SWEP generally works,
I get errors from the SWEP trying to "Index a nil
value." I know what a nil value is and I know what
the error means but I don't know what to fix it with.
Thanks for reading.

I will provide the SWEP's code here;

AddCSLuaFile( "cl_init.lua" )
AddCSLuaFile( "shared.lua" )

include('shared.lua')

function ENT:Initialize()
	
	self:SetModel( "models/jaanus/shuriken_small.mdl" )
	self:PhysicsInit( SOLID_VPHYSICS )
	util.PrecacheSound("physics/metal/sawblade_stick3.wav")
	util.PrecacheSound("physics/metal/sawblade_stick2.wav")
	util.PrecacheSound("physics/metal/sawblade_stick1.wav")
	util.PrecacheSound("weapons/shuriken/hit1.wav")
	util.PrecacheSound("weapons/shuriken/hit2.wav")
	util.PrecacheSound("weapons/shuriken/hit3.wav")
	self.Hit = { 
	Sound( "physics/metal/sawblade_stick1.wav" ),
	Sound( "physics/metal/sawblade_stick2.wav" ),
	Sound( "physics/metal/sawblade_stick3.wav" ) };
	self.FleshHit = { 
	Sound( "weapons/shuriken/hit1.wav" ),
	Sound( "weapons/shuriken/hit2.wav" ),
	Sound( "weapons/shuriken/hit3.wav" ) }
	self:GetPhysicsObject():SetMass( 2 )	
end

function ENT:Think()
	
	self.lifetime = self.lifetime or CurTime() + 20
	if CurTime() > self.lifetime then
		self:Remove()
	end
end

function ENT:Disable()
	self.PhysicsCollide = function()end
	self.lifetime = CurTime() + 30
end

function ENT:PhysicsCollide( data, phys )
	
	if self:GetVelocity():Length() < 250 then
		self:Disable()
		return
	end
	local Ent = data.HitEntity
	if !(ValidEntity( Ent ) || Ent:IsWorld()) then return end
	if Ent:IsWorld() then
		if data.OurOldVelocity:Normalize():Dot( data.HitNormal ) > .5 then
			self:SetPos( data.HitPos )
			self:SetAngles( data.OurOldVelocity:Angle() )
			self:GetPhysicsObject():EnableMotion( false )
			util.Decal( "ManhackCut", data.HitPos + data.HitNormal, data.HitPos - data.HitNormal )
			self:EmitSound( self.Hit[math.random(1,#self.Hit)] );
		end
		self:Disable()
	elseif Ent.Health then
		if not(Ent:IsPlayer() || Ent:IsNPC() || Ent:GetClass() == "prop_ragdoll") then 
			util.Decal( "ManhackCut", data.HitPos + data.HitNormal, data.HitPos - data.HitNormal )
			self:EmitSound( self.Hit[math.random(1,#self.Hit)] );
		end
		Ent:TakeDamage( 18, self:GetOwner() )
		self:SetPos( data.HitPos )
		self:SetParent( Ent )
		Ent:DeleteOnRemove( self )
		self:Disable()
		if (Ent:IsPlayer() || Ent:IsNPC() || Ent:GetClass() == "prop_ragdoll") then 
			local effectdata = EffectData()
			effectdata:SetStart( data.HitPos )
			effectdata:SetOrigin( data.HitPos )
			effectdata:SetScale( 1 )
			util.Effect( "BloodImpact", effectdata )
			self:EmitSound( self.FleshHit[math.random(1,#self.Hit)] );
			self:Remove() --Comment this line out if you want the shurikens to stick in ragdolls/npcs (shittily)
		end
	end
	
end

It's actually the init.lua file of the entity that the SWEP throws that provides errors.

So another "make it for me" thread ?.
Sorry, I'll pass

I would call it a 'Help Me' thread.
