Why is my data store system only temporarily storing my data?
I'm new to DataStoreSystems, but I watched this YouTube video on how to make one for my wins system, and even though the points go up, they don't permanently save. When I log back in, my wins just set back to 0. What did I do wrong?
local DataStoreService = game:GetService("DataStoreService")
local myDataStore = DataStoreService:GetDataStore("myDataStore")
game.Players.PlayerAdded:Connect(function(player) local leaderstats = Instance.new("Folder") leaderstats.Name = "leaderstats" leaderstats.Parent = player
local wins = Instance.new("IntValue")
wins.Name = "Wins"
wins.Parent = leaderstats
local data
local success, errormessage = pcall(function()
data = myDataStore:GetAsync(player.UserId.."-Wins")
end)
if success then
wins.Value = data
else
print("Data not saved from success")
warn(errormessage)
end
end)
game.Players.PlayerRemoving:Connect(function(player) local success, errormessage = pcall(function() myDataStore:SetAsync(player.UserId.."-Wins",player.leaderstats.Wins.Value) end)
if success then
print("Data successfully saved")
else
print("Data not saved")
warn(errormessage)
end
end)

This save system prevents hackers and it autosaves.
local PlayerStatManager = {}
local DataStoreService = game:GetService("DataStoreService")
local playerData = DataStoreService:GetDataStore("PlayerData")
local sessionData = {}
local AUTOSAVE_INTERVAL = 60
function PlayerStatManager:ChangeStat(player, statName, value)
local playerUserId = "Player_" .. player.UserId
assert(typeof(sessionData[playerUserId[statName]) == typeof(value), "ChangeStat error: types do not match"
if typeof(sessionData[playerUserId][statName]) == "number" then
sessionData[playerUserId][statName] = sessionData[playerUserId][statName] + value
else
sessionData[playerUserId][statName] = value
end
end
local function setupPlayerData(player)
local playerUserId = "Player_" .. player.UserId
local success, data = pcall(function()
return playerData:GetAsync(playerUserId)
end)
if success then
if data then
sessionData[playerUserId] = data
else
sessionData[playerUserId] = {Points=0, Experience=0}
end
end
local data = playerData:GetAsync(playerUserId)
if data then
sessionData[playerUserId] = data
else
sessionData[playerUserId] = {Points=0, Experience=0}
end
else
warn("Cannot access data stor for player!")
end
end
local function savePlayerData(playerUserId)
if sessionData[playerUserId] then
local tries = 0
local success
repeat
tries = tries + 1
success = pcall(function()
playerData:SetAsync(playerUserId, sessionData[playerUserId])
end)
if not success then wait(1) end
until tries == 3 or success
local success, err = pcall(function()
playerData:SetAsync(playerUserId, sessionData[playerUserId])
end)
if not success then
warn("Cannot save data for player!")
end
end
end)
local function saveOnExit(player)
local playerUserId = "Player_" .. player.UserId
savePlayerData(playerUserId)
end
local function autoSave()
while wait(AUTOSAVE_INTERVAL) do
for playerUserId, data in pairs(sessionData) do
savePlayerData(playerUserId)
end
end
end
spawn(autoSave)
game.Players.PlayerAdded:Connect(setupPlayerData)
game.Players.PlayerRemoving:Connect(saveOnExit)
return PlayerStatManager
Although, This is the standard script from ROBLOX script thing idk what it is called but it's from ROBLOX.
Line 12 is still one big line, the answer bar did not have enough room.
