ModuleScripts only loading its default values?

[Xzx3l]

I’ve been working with ModuleScripts recently, and I am having an issue right now.

Apparently, whenever I require any ModuleScripts, it loads ONLY its default values.
It doesn’t load anything that has been inserted to it after the game loaded

Here´s an example where I printed how much money the server had when the game first loaded (By default it’s 0)

local Values = {
	
	Money = 0,

	
}

return Values

Then, I call a function that goes something like this:

ServerValues.Money = ServerValues.Money + QuantityToGive

Once I’ve done that, I try to print the money once again, and it prints 0

This seems to happen either if I require the ModuleScript from client or server side

Somehow the game still manages to know the new values of the ModuleScripts, cause when I need to know how much money I have, it works

if ServerValues.Money < TotalPrice then
		
		dialogRequestEvent:InvokeClient(player, {"cantAfford",TotalPrice - ServerValues.Money})
		
	elseif ServerValues.Money >= TotalPrice then
		
		dialogRequestEvent:InvokeClient(player, {"proceedToBuy",TotalPrice})

end

Long story short, the ModuleScript can be edited, but when I try to use for displaying its values or something like that, it just returns its default values.

Is there any explanation for this?

Needs more detail, for example:

Did you add the money via the command bar? That would explain why

During runtime, the return values for modules are cached for the context the script runs in (e.g client, server, or an actor vm); This is why you can use modules to share information/communicate between different scripts on the same context

However, for the command bar, it runs in edit-time instead of runtime, so the behaviour is different. If a command bar edits a value in a ModuleScript, the next time it runs the value won’t be cached, otherwise that’s just a waste of memory.

This is a great explanation!

I’ll give you a example on how I setup my modulescripts

local module = {}

module.Money = 0

function module:AddMoney(MoneyToAdd: number)
   module.Money += MoneyToAdd
end

return module

This is imo a clean way to setup the module

Example of using this module:

local module = require(PATH.TO.MODULE.module)

-- Before changes
print(module.Money)

-- Change money value
module:AddMoney(50)

-- After changes
print(module.Money)

Hope this helps for a better understanding of modulescripts!

No, I’m adding the money in a normal script

print(ServerValues.Money)
ServerValues.Money = ServerValues.Money + cashToGive
print("Added money!")
print(ServerValues.Money)

In this case it worked perfectly

That would explain why whenever I try to get the Module values, it always returns the default ones, not the new ones.

However, Im going through a new problem;

It seems to succesfully require the Module data from server scripts, but I did this in a LocalScript for testing purposes:

local serverValues = require(ReplicatedStorage.Libraries.ServerValues)

while task.wait(5) do
	print(serverValues.Money)
end

And this time, I get the issue back. It seems to not be loading the new data of the module

It doesn’t matter how many times I override the money value, it ALWAYS returns 0, even trying to display it in a frame, it’s always returning the starting data

Hello, as I said earlier, module return values are only cached for code running within the same context, so if say, you changed the value from the server, and tried to access it from the client, the server and client are different contexts so the client will not see the changes made by the server.

I see, I understand it now, thanks. So I need to make the changes everytime from both sides. Is it reliable to use a remote event to override the module data everytime it changes or is there any better way?

[athar_adv (athar_adventure)]

Honestly the way I replicate my data for display on the client is just using ReplicatedRegistry, it abstracts the remote events from the data replication, also pretty easy to use

Though any other solution like ReplicaService or just raw remote events works fine, this is just the way I do it

Modulescripts are not replicating values to the client. They are loaded only at server start.
