What is a safe way to transfer server-only data from one server script to another?

[Aorda]

I wish to transfer a table from one server script to another. However, this table should never be exposed to the clients, and therefore, I cannot use a BindableFunction. I tried to use a module script, but the data does not update on the second script when I do that. Cloning the module also didn’t help.

With that being said, I would appreciate any ideas regarding the issue.

You can use DataStore or _G for global variables

@jaschutte

If you know what module scripts are, _G is basicly the default ‘module’ script.
_G is a table, so you can assign it keys and values like any other table, but the special thing about _G is that it saves cross-script.
Let’s say you have 2 scripts. In the first script you write:

local LocalValue = "This is not saved across scripts"
_G.GlobalValue = "This is saved across scripts"

Now if you have another script with the following:

print(LocalValue) --this will print nil, localvalue was only defined in the other script
print(_G.GlobalValue) --this will print 'This is saved across scripts' because that's how _G works

_G can be usefull for storing things like player money, usually you have multiple scripts which need to know how much money a player has. So with _G you can easily store that across scripts.

--script 1
_G.PlayerCash = 10 --gives the player 10 cash
--script 2
_G.PlayerCash = _G.PlayerCash + 5 --adds 5 to player cash
--script 3
print(_G.PlayerCash) --prints out 15

In short: _G is a table which saves across scripts.
If you heared of module scripts, _G is basicly that.

Important thing to note:
_G IS NOT SLOWER THAN MODULESCRIPTS. It makes no difference if you use _G or require(modulescript) both do the exact same thing and both are as fast.

Use ModuleScripts instead, not sure why you recommended the DataStoreService since it isn’t necessary for cross-script communication.

You would actually use a specific script architecture to actually transfer between environments.

Something is not clear here, what are you trying to do here?

I cannot use a BindableFunction

I think you might be confused about BindableEvents. Only RemoteEvents or RemoteFunctions can go from client > server or server > client. BindableEvents/BindableFunctions are only server > server or client > client, they cannot be accessed by the other in any way.

If you’re that worried, you should just store the BindableEvent/Function inside somewhere like ServerScriptService or ServerStorage where the client can never see into.
