Gmod 12 custom bullet goes throught npcs but not parts of the world.

[buu342]

Simple. The custom bullet im making (BASED OFF the rocket from dans_SNPCS) throught npc's but not parts of the world and props. What is wrong with my script?

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

include('shared.lua')

//ENT.CanExplode = false

function ENT:Initialize()
local function ICanExplode()
self.CanExplode = true;
end

math.randomseed(CurTime())

self.firesound = CreateSound(self,"weapons/rpg/rocket1.wav")

self.exploded = false
self.Entity:SetModel( "models/weapons/w_missile_launch.mdl" )
self.Entity:PhysicsInit( SOLID_VPHYSICS ) -- Make us work with physics,
self.Entity:SetMoveType( MOVETYPE_VPHYSICS ) --after all, gmod is a physics
self.Entity:SetSolid( SOLID_VPHYSICS ) -- Toolbox
//self.Entity:SetMaterial("models/props_combine/stasisshield_sheet")
util.SpriteTrail(self, 0, Color(255,255,255,179), false, 12, 1, 4, 1/(10+1)*0.5, "trails/smoke.vmt");
//self.Entity:SetColor(0,0,0,255)
//self.Entity:Ignite( 120, 40 )

self.dietime = CurTime() + 4

self.firesound:Play()
local phys = self.Entity:GetPhysicsObject()
if (phys:IsValid()) then
phys:Wake()
phys:EnableGravity(false)
end

//timer.Simple(1,ICanExplode())
end

function ENT:OnTakeDamage( dmginfo )

self.Entity:TakePhysicsDamage( dmginfo )

end

function ENT:PhysicsCollide()
if ( self.exploded == false) then
util.BlastDamage(self.Entity, self.Entity, self.Entity:GetPos(), 100, 250)

local effectdata = EffectData()
effectdata:SetOrigin(self.Entity:GetPos())
util.Effect( "Explosion", effectdata )

self.exploded = true
self:EmitSound("weapons/explode3.wav")
self.firesound:Stop()
print("Exploded due to collision with world")
end
end

function ENT:Think()

if ( self.dietime < CurTime() ) then
util.BlastDamage(self.Entity, self.Entity, self.Entity:GetPos(), 100, 250)

local effectdata = EffectData()
effectdata:SetOrigin(self.Entity:GetPos())
util.Effect( "Explosion", effectdata )

self.exploded = true
self:EmitSound("weapons/explode3.wav")
self.firesound:Stop()
print("Exploded due to time out")
end

if self.exploded == true then self:Remove() end
self:NextThink( CurTime() )
return true
end
/*
function ENT:Touch()
if ( self.exploded == false) then
util.BlastDamage(self.Entity, self.Entity, self.Entity:GetPos(), 100, 250)

local effectdata = EffectData()
effectdata:SetOrigin(self.Entity:GetPos())
util.Effect( "Explosion", effectdata )

self.exploded = true
self:EmitSound("weapons/explode3.wav")
self.firesound:Stop()
print("Exploded due to collision")
end
end

So how can i make it so that the projectile hits the npc and explodes. Its hard to kill floating npcs if i can't shoot a rocket at it.

Thanks.
