How can i make _G shared across server/clients

Help and Feedback Scripting Support
#1

Basically I need a way or something like _G that is shared across clients and the server, And I do need it to be a table
And for it to be auto updated like in the example below

-- LocalScript
local X = {"MintIceCream"}
_G.INFO = X
X.INFO[1] = "ChocolateIceCream"

-- ServerScript
local X = _G.INFO
Print(X)
-- Output: ChocolateIceCream
-- (output is just an example and its not actually wokring since its a localscript to serverscript)

It said "ChocolateIceCream" even though in the localscript i set _G.INFO = X before changing the X[1] to "ChocolateIceCream"

I do know if _G.INFO is nil i can just put a event and do shenanigans

The client and the server have different function environment so your example will not work, the best would be to use remote events

What I would do is create a module script to be later changed instead of _G

For my games I do

local Globals = {}

warn("Loaded!")
--==//Services\\\==--
local rs = game:GetService("ReplicatedStorage")

local players = game:GetService("Players")

local debris = game:GetService("Debris")


local Modules = game:GetService("ReplicatedStorage"):WaitForChild("Modules")

local IsLoaded  = false
--==//Globals\\\==--
function Set()
	local Remotes = rs:WaitForChild("Remotes")

	for _,v in ipairs(Remotes:GetChildren()) do
		_G[v.Name] = Remotes:WaitForChild(v.Name)
	end


	for _,v in ipairs(Modules:GetChildren()) do
	
		if v:GetAttribute("Blacklisted") then continue end
		_G[v.Name] = require(v)
	end
	IsLoaded = true
end


--==//----\\\==--


_G.rs = rs

_G.debris = debris

_G.players = players



Globals["Client"] = function()
	_G.player = players.LocalPlayer
	_G.Camera = game:GetService("Workspace").CurrentCamera

end


function Globals:Wait()
	Set()
	repeat task.wait()

	until IsLoaded
end

--[[



local player = game:GetService("Players").LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()

local Starter_Module = require(game:GetService("ReplicatedStorage"):WaitForChild("Modules"):WaitForChild("Global"))
Starter_Module:Wait()


if character then
	warn('Loaded')
	_G["Skills"]:SetUp()
	_G["Skills"]["Gojo"]()
end


]]
return Globals

Client

local Starter_Module = require(game:GetService("ReplicatedStorage"):WaitForChild("Modules"):WaitForChild("Global"))
Starter_Module:Wait()

Server

local Starter_Module = require(game:GetService("ReplicatedStorage"):WaitForChild("Modules"):WaitForChild("Global"))
Starter_Module:Wait()

I dont know how module scripts actually working like, I dont know you can update/store things on there. The thing is I already made the variables and the functions on the localscript

#7

As a note, modules will act the same as _G; Server will see the module as one while the client will see the module as another

Best usage would be to get a RemoteFunction and use a module as a storage between the two

Will the example with the minticecream and the chocolateicecream work or not?

#9

As others have said, you’d have to replicate the data using Remote events.

Additionally, I’ve actually made an open-source package for this scenario:

It’s still being documented and tested, but If you’re interested, check it out.

#10

It won’t work in exactly the same way, but you could create a WRITE and READ arguments for the InvokeServer

LocalScript

RemoteFunction:InvokeServer("WRITE",'MintIceCream','ChocolateIceCream')
task.wait(3)
RemoteFunction:InvokeServer("READ",'MintIceCream') -->ChocolateIceCream

Script

RemoteFunction.OnServerInvoke = function(Player, Operation, Key, Value)
if not Storage[Player] then Storage[Player]={} end;

if Operation == 'WRITE' then
Storage[Player][Key] = Value; return true;
elseif Operation == 'READ' then
return Storage[Player][Key] or nil;
end;

end;

I dont think I can really use that since that’s really close to a datastore, And its not going to work, My only idea is a table shared across a server/clients nothing more

#12

I’ll try it out, Thanks for making a module, (I’m not used to using modules)

#13

That’s exactly what it does.

You won’t be able to share variables between the client and the server otherwise.

#14

I do have an idea, I dont know how to do it though. Its that the server has a table and the client has a different one, so when the client table changes/updates it overwrites the server table and the other way around.

#15

As I have mentioned, you can’t replicate client changes to the server without a remote event or a remote function.

What I have sent is the most basic way to share a table between the server-client while also keeping other clients secure.

#16

Oh you did that to make it secure for other clients, I were making the server size 1 and its not for that reason only, The only reason I have it on a script is because I needed to use Loadstring

#17

Without external remotes/modules, No you cant. (atleast that’s what i think so)

#18

Ill use remotes, That’s fine I just need to think of a way to do it.
