I inserted ModuleScript at ServerStorage and put the script below but it doesn't work?
-- Set up table to return to any script that requires this module script local PlayerStatManager = {} local DataStoreService = game:GetService("DataStoreService") local playerData = DataStoreService:GetDataStore("PlayerData") -- Table to hold player information for the current session local sessionData = {} local AUTOSAVE_INTERVAL = 60 -- Function that other scripts can call to change a player's stats function PlayerStatManager:ChangeStat(player, statName, value) assert(typeof(sessionData[playerUserId][statName]) == typeof(value), "ChangeStat error: types do not match") local playerUserId = "Player_" .. player.UserId if typeof(sessionData[playerUserId][statName]) == "number" then sessionData[playerUserId][statName] = sessionData[playerUserId][statName] + value else sessionData[playerUserId][statName] = value end end -- Function to add player to the 'sessionData' table local function setupPlayerData(player) local playerUserId = "Player_" .. player.UserId local data local success, err = pcall(function() playerData:UpdateAsync(playerUserId, function(playerData) data = playerData end) end) if success then if data then -- Data exists for this player sessionData[playerUserId] = data else -- Data store is working, but no current data for this player sessionData[playerUserId] = {Money=0, Experience=0} end else warn("Cannot set up data for player!") end end -- Function to save player's data local function savePlayerData(playerUserId) if sessionData[playerUserId] then local success, err = pcall(function() playerData:SetAsync(playerUserId, sessionData[playerUserId]) end) if not success then warn("Cannot save data for player!") end end end -- Function to save player data on exit local function saveOnExit(player) local playerUserId = "Player_" .. player.UserId savePlayerData(playerUserId) end -- Function to periodically save player data local function autoSave() while wait(AUTOSAVE_INTERVAL) do for playerUserId, data in pairs(sessionData) do savePlayerData(playerUserId) end end end -- Start running 'autoSave()' function in the background spawn(autoSave) -- Connect 'setupPlayerData()' function to 'PlayerAdded' event game.Players.PlayerAdded:Connect(setupPlayerData) -- Connect 'saveOnExit()' function to 'PlayerRemoving' event game.Players.PlayerRemoving:Connect(saveOnExit) return PlayerStatManager
ModuleScripts
need to be required for their contents to run. Try making another script that requires your module like so.
local Module = game:GetService("ServerStorage"):WaitForChild("ModuleScript") require(Module)
