【问题描述】：

所以我正在尝试制作游戏，但无法保留统计数据。我已经有一个有效的死亡计数器，但不知道如何保存它，每次我重新加入时它都会重置。这是我尝试过的两个代码：

local pointsDataStore = game:GetService("DataStoreService"):GetDataStore("Deaths")

game.Players.PlayerAdded:Connect(function(player)
    local playerKey = "Player_" .. player.UserId

    local success, err = pcall(function()
        pointsDataStore:UpdateAsync(playerKey, function(oldValue)
            local newValue = oldValue or 0
            newValue = newValue + 0
            return newValue
        end)
    end)
end)

local DS = game:GetService("DataStoreService"):GetDataStore("Points")

game.Player.PlayerAdded:connect(plr)
    local leaderstats = Instance.new("Model",plr)
    leaderstats.Name = "leaderstats"

    local currency = Instance.new("IntValue", leaderstats)
    currency.Name = "Deaths"
    currency.Value = 1

   while wait(5) do
    DS:SetAsync(plr.userId.."_DS", currency.Value)
  end
end)

我会在玩家加入时从数据存储中加载值，然后在每次死亡时递增它并将其保存到数据存储中。

注意，为了触发死亡，脚本使用Humanoid.Died 事件。

local deathsStore = game:GetService("DataStoreService"):GetDataStore("Deaths")

function playerAddedHandler(plr)  
    -- key that is used to store the death value
    local playerKey = "Player_" .. plr.UserId 

    -- Add leader board
    local leaderstats = Instance.new("Folder", plr)  
    leaderstats.Name = "leaderstats"

    -- Add "Deaths" column to leader board 
    local deaths = Instance.new("IntValue", leaderstats)
    deaths.Name = "Deaths"

    -- Load Deaths value from previous game
    deaths.Value = deathsStore:GetAsync(playerKey) 

    -- Hook up event handler that is triggered when character dies
    plr.CharacterAdded:Connect(function(char)
        char.Humanoid.Died:Connect(function()

            -- increment death value on the leader board
            plr.leaderstats.Deaths.Value = plr.leaderstats.Deaths.Value + 1

            -- save the value in our deaths datastore
            local success, err = pcall(function()
                deathsStore:SetAsync(playerKey, plr.leaderstats.Deaths.Value)
            end)    
        end)
    end)
end

game.Players.PlayerAdded:Connect(playerAddedHandler) -- call function "playerAddedHandler" every time a player joins the game

还有。不要忘记启用数据存储使用，否则会在输出中显示 403 错误。您可以在 roblox 网站上的游戏基本设置中执行此操作：
