範例程式碼
按時間檢索 DataStore 版本
local DataStoreService = game:GetService("DataStoreService")
local dataStore = DataStoreService:GetDataStore("DataStore")
local key = "key-123"
function setData(data)
local success, result = pcall(function()
dataStore:SetAsync(key, data)
end)
if not success then
warn(result)
end
end
function getVersionAtTime(timestamp)
local success, result, keyInfo = pcall(function()
return dataStore:GetVersionAtTimeAsync(key, timestamp.UnixTimestampMillis)
end)
if success then
if result == nil then
print("在此時間找不到版本")
else
print(result, keyInfo.Version)
end
else
warn(result)
end
end
-- 在 2024/12/02 6:00 UTC 之前運行
setData("version 1")
-- 在 2024/12/02 9:00 UTC 之前運行
setData("version 2")
-- 打印 "在此時間找不到版本"
local time1 = DateTime.fromUniversalTime(2024, 12, 02, 05, 00)

範例程式碼
使用日期過濾器檢索數據存儲版本
local DataStoreService = game:GetService("DataStoreService")
local experienceStore = DataStoreService:GetDataStore("PlayerExperience")
local time = DateTime.fromUniversalTime(2020, 10, 09, 01, 42)
local listSuccess, pages = pcall(function()
return experienceStore:ListVersionsAsync("User_1234", nil, time.UnixTimestampMillis)
end)
if listSuccess then
local items = pages:GetCurrentPage()
for key, info in pairs(items) do
print("鍵:", key, "; 版本:", info.Version, "; 創建時間:", info.CreatedTime, "; 已刪除:", info.IsDeleted)
end
