Loadstring() not working properly?

Help and Feedback Scripting Support
#1

I’m trying to make an SB system with loadstring() and vLua, I’ve figured out how to get localscripts working with vLua, but loadstring() is erroring for some odd reason.

Error:

Workspace.Script:11: attempt to call a nil value - 48

Code (Serverside):

function LoadSS(player, _script)
	local newVariables = {
		["NLS"] = "function(str) local str = str..'local owner = game.Players[\'"..player.Name.."\'] ' print(str) game.ReplicatedStorage.LoadLocal:FireClient(owner, str) end ";
	}
	
	local NS = "local owner = game.Players['"..player.Name.."'] "
	for name, code in pairs(newVariables) do
		NS = NS .. "local "..name .." = "..code .. " "
	end
	NS ..= _script
	print(NS)
	local Successful, Response = pcall(function() local s = loadstring(NS)() return s end)
	return Response
end

-- This code is just an example that I've written a while ago for VSB

wait(5)

local a = LoadSS(game.Players:WaitForChild('infiniteRaymond'), [[
local p = owner
local char = p.Character
local p = Instance.new('Part', char)
p.Name = "CameraPart"
p.Anchored = true
p.CanCollide = false
local m = Instance.new('SpecialMesh', p)
m.MeshId = "rbxassetid://2540333271"
m.TextureId = "rbxassetid://2540333290"
m.Scale = Vector3.new(1,1,1)
local remote = Instance.new('RemoteEvent', char)
remote.Name = "CameraRemote"
remote.OnServerEvent:Connect(function(player, cf)
	p.CFrame = cf * CFrame.Angles(0, math.rad(180), 0)
end)
NLS("
local p = game.Players.LocalPlayer
local char = p.Character

local remote = char.CameraRemote
local part = char.CameraPart

part.Transparency = 1

game:GetService('RunService').Heartbeat:Connect(function()
	remote:FireServer(workspace.CurrentCamera:GetRenderCFrame())
end)
", char)
]])

print(a)

It prints the script with the NLS and owner code at the top, but still errors none-the-less.
Am I using loadstring() wrong?

#2

Has loadstring been enabled? It’s the LoadStringEnabled property of ServerScriptService.

Do you know which line is line 11?

#5

Its this line:

I believe this is coming from the NLS function, as removing the code that runs the NLS function makes it not error.

But I also have a problem where it doesn’t catch output, but I can fix that easily.

#6

It’s saying you’re attempting to call a nil value, so that might mean that pcall is nil. Are you sure that’s the line that’s erroring?

#7

Yes, it’s the line that’s erroring.

#8

Then that’s the only possible issue that I can think of.

#9

Well, when I run the NLS code, it works perfectly fine:

local owner = game.Players:WaitForChild('infiniteRaymond')
wait(2)
local NLS = function(str)
	local str = str..'local owner = game.Players["infiniteRaymond"] '
	print(str)
	game.ReplicatedStorage.LoadLocal:FireClient(owner, str)
end 
NLS("print('test')")

Edit: OK, I’m just confused.

I don’t know if it’s the SB or the script i’m using to test, but other things with the NLS function seem to work fine…
