Why is my table returning nil (print)

Help and Feedback Scripting Support

Hello, i’m new to working with tables to store stats.
i understand the basics now.

But i don’t understand why my local script for updating text is returning nil?
i think it might be because the stats for players are server sided and the local script is accessing the module script locally?

Local script(the one i have trouble with):


local datamodule = require(game.ReplicatedStorage.datamodule)
local playerdata = datamodule.getdata()

print(playerdata[game.Players.LocalPlayer.UserId]["stats"].gold) -- problematic line

script.Parent.Text = playerdata[game.Players.LocalPlayer.UserId]["stats"].gold

module script :

local datahandler = {}

local template = {["stats"] = {
	gold = 10,
	items = {}
}}

local playerTable = {}

function datahandler.getdata()
	return playerTable
end

function datahandler.addplayer(player, data)
	if player:IsA("Player") then
		if not data then
			playerTable[player.UserId] = table.clone(template)
		else
			playerTable[player.UserId] = data
		end
	else
		warn("not a player")
	end
end

function datahandler.removeplayer(player)
	if player:IsA("Player") then
		playerTable[player.UserId] = nil
	end
end

return datahandler

serverscript for stats:



local datamodule = require(game.ReplicatedStorage.datamodule)

game.Players.PlayerAdded:Connect(function(player)
	datamodule.addplayer(player)
	
	local playerdata = datamodule.getdata()
	
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	
	local gold = Instance.new("IntValue")
	gold.Name = "gold"
	gold.Value = playerdata[player.UserId]["stats"].gold
	gold.Parent = leaderstats
end)

local function updateleaderstats(player)
	for _, v in pairs(player.leaderstats:GetChildren()) do
		v.Value = datamodule.getdata()[player.UserId]["stats"][v.Name]
	end
end

game.Players.PlayerRemoving:Connect(function(player)
	datamodule.removeplayer(player)
end)

game.ReplicatedStorage.RemoteEvent.OnServerEvent:Connect(function(player)

	local playerdata = datamodule.getdata()
	playerdata[player.UserId]["stats"].gold += 1
	
	updateleaderstats(player)
end)

Please, i really need help with this. Thank you for any responses. :smiley:

Yep you are correct, it does not replicate you will need attributes or remote function to handle this problem.

That makes my code unnecessarily complicated, i thought of doing that, are there any alternatives?
I wanted to use tables and modules to make it more simple for me :ˇ(

I feel ya, roblox dev is complicated.

Unfortunately, it is necessary.

If you want to simplify it you can use someone elses module that does this hardwork for you.

Edit: wow the server script in the module has 1000 lines. You probably dont need all the functionality just parts of it if you want to do it on your own.

wait why doesn’t

local playerdata = game.ReplicatedStorage.RemoteEvent:FireServer("getdata")

script.Parent.Text = playerdata

game.ReplicatedStorage.RemoteEvent.OnServerEvent:Connect(function(player, request)
	local playerdata = datamodule.getdata()
	
	if request == "getdata" then
		return playerdata[player.UserId]["stats"].gold
	end
end)

work?, am i missing something? maybe i’m too tired :frowning:

While trying to get it from client. And its not replicating.

You will need a remote function, and also some sleep, good luck.
