So a while ago I wanted to make a Lua console, but that idea kind of died out since the code runs on the server, but then I saw the Lua VM module, and I decided to try and use it, but I never got it to work.
Server script inside of ServerScriptService:
local vm = require(game.ReplicatedStorage.Loadstring)
vm([[print("Hello world!")]])
Any help is appreciated!
Yes I already made another topic like this, but that was like 2 months ago and it has no replies so who cares.
is there a function inside of the module loadstring you can use? cos rn ur just calling a module as a function
The module that is the parent to all the modules returns a function:

local waitDeps = {
'Rerubi';
'LuaK';
'LuaP';
'LuaU';
'LuaX';
'LuaY';
'LuaZ';
}
for i,v in pairs(waitDeps) do script:WaitForChild(v) end
local luaX = require(script.LuaX)
local luaY = require(script.LuaY)
local luaZ = require(script.LuaZ)
local luaU = require(script.LuaU)
local rerubi = require(script.FiOne)
luaX:init()
local LuaState = {}
getfenv().script = nil
return function(str,env)
local f,writer,buff,name
local env = env or getfenv(2)
local name = (env.script and env.script:GetFullName())
local ran,error = pcall(function()
local zio = luaZ:init(luaZ:make_getS(str), nil)
if not zio then return error() end
local func = luaY:parser(LuaState, zio, nil, name or "nil")
writer, buff = luaU:make_setS()
luaU:dump(LuaState, func, writer, buff)
f = rerubi(buff.data, env)
end)
if ran then
return f,buff.data
else
return nil,error
end
end
Also, I’ve seen a few posts about Lua VM and it says to do what I am doing:
local vm = Path.to.Module
vm("your code")
Any errors? Also why do you have all those brackets and stuff, why not just do
vm("print("Hello world!"))
Hey, sorry for the late response, I went to bed before you posted the reply, there is school today so I won’t be able to respond for a while, but, the brackets are basically a way of writing multiline strings, I used then so I could use normal quotation marks, and there were no errors, and nothing was in the output at all.
EDIT: vm("print("Hello world!")) would give an error because you didn’t close the starting string, and because a string that was started and ended with a " can’t have " inside of it.
My bad, forgot to think of that. Try this
vm("print('Hello world!')" )
If " is being used always use '
I found one VM module myself, I got it working but it seems to work differently, now I can’t find it in the library but I have it saved in my games here’s an example of how to use it:
require(pathtomodule)(codehere)()
I have no idea why it’s formatted like that,
Link:I’ll post it later since I can’t rn on mobile
If you want to use loadstring on the server, see LoadStringEnabled. Since the module is in ReplicatedStorage though you probably want to use it on the client.
This won’t do anything since vm here only turns the passed code into a function. You need to call the result:
vm([[print("Hello world!")]])()
But loadstring is dangerous, and that’s a valid reason why we use custom loadstrings instead
No, it’s only as dangerous as using a custom loadstring module which @Babybunnyiscute19 is already doing.
