[HELP] Simple Prop Protection causing CalcView error

[Develio13]

Hi,

I've been looking for a script that can deal damage to all props in garrys mod and have found exactly what I'm looking for, how ever it's causing some issues and I'm hoping someone knows why it's not working :D

>> Addons >> SPD >> LUA >> AUTORUN >> SERVER >> spd.LUA

if !ConVarExists("spd") then CreateConVar("spd", '5', FCVAR_NOTIFY) end
if !ConVarExists("spd_fire") then CreateConVar("spd_fire", '2', FCVAR_NOTIFY) end

local function SPD_Main_Dmg_Hook(ent, inflictor, attacker, amount)
local con_spd_val = GetConVarNumber("spd") --Since we only need to call it once and we are going to use the val twice...
--There is a reason for the order of operations
--We don't call the function unless we have too (and therefore avoid a useless overhead)
if ent and ent.IsValid and (con_spd_val > 0) and ent:IsValid() then
if not ent.SPD_Data then ent.SPD_Data = {} end

--The reason this is in 2 steps is that I don't want short cut evaluation biting us in the ass
--Because both the value nil and the value false equates to false in a boolean check
if ent.SPD_Data.Invalid then
return
elseif (ent.SPD_Data.Invalid == nil) and (not (ent:GetClass() ~= "prop_physics" or ent:Health() == 0)) then
ent.SPD_Data.Invalid = true
return
else
ent.SPD_Data.Invalid = false
end

if not ent.SPD_Data.Health then ent.SPD_Data.Health = ent:GetPhysicsObject():GetMass() end

local e_pos = ent:GetPos()
local mass = ent:GetPhysicsObject():GetMass()
local colmod = ent.SPD_Data.Health / mass

ent.SPD_Data.Health = ent.SPD_Data.Health - amount / con_spd_val
ent:SetColor(255, 255 * colmod, 255 * colmod, 255)

if math.random(1, 100) < GetConVarNumber("spd_fire") then
ent:Ignite(10, 20)
end

if ent.SPD_Data.Health < (mass * 0.5) then
ent:GetPhysicsObject():EnableMotion(true)
end

if (ent.SPD_Data.Health < (mass * 0.25)) and ent:IsConstrained() then
local effect = EffectData()
effect:SetStart(e_pos)
effect:SetOrigin(e_pos + Vector(0, 0, 10))
effect:SetScale(mass)
util.Effect("cball_explode", effect)
constraint.RemoveAll(ent)
end

if ent.SPD_Data.Health < 0 then
local effect = EffectData()
effect:SetStart(e_pos + Vector(0, 0, 10)) -- this was missing pos
effect:SetOrigin(e_pos + Vector(0, 0, 10))
effect:SetScale(mass)
util.Effect("Explosion", effect)
ent:Remove()
end
end
end
hook.Add("EntityTakeDamage", "spdEntityTakeDamage", SPD_Main_Dmg_Hook)

When someone is killed, after being in a vehicle i get the following error message.

ERROR: GAMEMODE:'CalcView' Failed: base/gamemode/cl_init.lua:443: attempt to call method 'GetVehicle' (a nil value)

and it loops until you exit the game.

I'm using the original sandbox game mode, and the other mods seem to work fine, such as PHX, WireMod and some others.

I hope someone knows the cause of this issue and can provide a solution, as it renders this entire script useless.

Thank you,
