如何修复 roblox 中的数据

Question

我问了第二个问题，因为我的最后一个问题是带着评论离开主题。所以我试图让 roblox 保存玩家的统计数据，但它总是保存基本统计数据。即使玩家已经玩过。这是我的代码：

local HttpService = game:GetService("HttpService")
local DataStoreService = game:GetService("DataStoreService")
local ds = DataStoreService:GetDataStore("Data")

game.Players.PlayerAdded:Connect(function(player)
    local defaultData = {
        coins = 0,
        gems = 0,
        xp = 0,
        level = 1,
        maxstamina = 100,
        maxmagic = 100,
    }
    local loadedData = defaultData
    local success, result = pcall(function()
         return ds:GetAsync(player.UserId)
    end)
    if success then
        if result then
            -- if we've successfully loaded the data, parse the stored json data
            print(string.format("An old player named %s has returned with data : %s!", player.Name, tostring(result)))
            -- player data should look like this :
            -- {"coins":0,"xp":0,"gems":0,"level":1,"maxstamina":100,"maxmagic":100}
            local parseSuccess, parseResult = pcall(function()
                return HttpService:JSONDecode(result)
            end)
            if parseSuccess then
                loadedData = parseResult
            else
                warn(string.format("Failed to parse %s with error : %s", tostring(result), tostring(parseResult))) 
            end
        else
            -- we have a new player
            print(string.format("New player named %s has joined!", player.Name))
        end
    else
        warn(string.format("Something went wrong fetching %s's data : %s", player.Name, tostring(result)))
        -- TO DO: FIGURE OUT HOW YOU WANT TO HANDLE THIS ERROR.
        -- IF YOU DO NOTHING, THE PLAYER'S DATA WILL BE THE DEFAULT DATA USED FOR
        -- NEW PLAYERS
    end

    -- create the leaderstats and hidden values, load the data from the loadedData table
    local leaderstats = Instance.new("Model", player)
    leaderstats.Name = "leaderstats"

    local hidden = Instance.new("Model", player)
    hidden.Name = "hidden"

    local coins = Instance.new("IntValue", leaderstats)
    coins.Name = "Coins"
    coins.Value = loadedData.coins

    local gems = Instance.new("IntValue", leaderstats)
    gems.Name = "Gems"
    gems.Value = loadedData.gems

    local level = Instance.new("IntValue", leaderstats)
    level.Name = "Level"
    level.Value = loadedData.level

    local xp = Instance.new("IntValue", hidden)
    xp.Name = "XP"
    xp.Value = loadedData.xp

    local maxstamina = Instance.new("IntValue", hidden)
    maxstamina.Name = "MaxStamina"
    maxstamina.Value = loadedData.maxstamina

    local maxmagic = Instance.new("IntValue", hidden)
    maxmagic.Name = "MaxMagic"
    maxmagic.Value = loadedData.maxmagic

    local stamina = Instance.new("IntValue", hidden)
    stamina.Name = "Stamina"
    stamina.Value = loadedData.maxstamina

    local magic = Instance.new("IntValue", hidden)
    magic.Name = "Magic"
    magic.Value = loadedData.maxmagic
end)

game.Players.PlayerRemoving:Connect(function(player)
    local stats = player.leaderstats
    local hidden = player.hidden

    local data = {
        coins = stats.Coins.Value,
        gems = stats.Gems.Value,
        xp = hidden.XP.Value,
        level = stats.Level.Value,
        maxstamina = hidden.MaxStamina.Value,
        maxmagic = hidden.MaxMagic.Value,
    }

    -- wrap the request in a try-catch block to ensure that failures don't throw errors
    local success, result = pcall(function()
        -- save all the data as a JSON string
        ds:setAsync(player.UserId, HttpService:JSONEncode(data))
    end)
    if not success then
        warn(string.format("Failed to save %s's data with error : %s", player.Name, tostring(result)))
        -- TO DO: FIGURE OUT HOW YOU WANT TO HANDLE THIS ERROR.
        -- IF YOU DO NOTHING, THE PLAYER WILL LOSE THIS SESSION'S DATA
    end 
end)

我更改了答案：

所以我们必须使用 DataStore2 才能正常工作！

这里有一个很好的 DataStore2 教程：https://www.youtube.com/watch?v=hBfMfB0BwGA

这是我的最终代码：

local DataStore2 = require(1936396537)

local defaultCoins = 0
local defaultGems = 0
local defaultLevel = 1
local defaultXP = 0
local defaultMStamina = 100
local defaultMMagic = 100

DataStore2.Combine("Data","coins","gems","level","xp","mstamina","mmagic")

local xpToLevelUp = function(level)
    return 100 + level * 5
end

game.Players.PlayerAdded:Connect(function(player)
    local coinsDataStore = DataStore2("coins",player)
    local gemsDataStore = DataStore2("gems",player)
    local levelDataStore = DataStore2("level",player)
    local xpDataStore = DataStore2("xp",player)
    local mstaminaDataStore = DataStore2("mstamina",player)
    local mmagicDataStore = DataStore2("mmagic",player)

    local stats = Instance.new("Folder",player)
    stats.Name = "stats"

    local coins = Instance.new("IntValue",stats)
    coins.Name = "Coins"

    local gems = Instance.new("IntValue",stats)
    gems.Name = "Gems"

    local level = Instance.new("IntValue",stats)
    level.Name = "Level"

    local xp = Instance.new("IntValue",stats)
    xp.Name = "XP"

    local mstamina = Instance.new("IntValue",stats)

            levelDataStore:Increment(1)

    end

    coinsUpdate(defaultCoins)
    gemsUpdate(defaultGems)
    levelUpdate(defaultLevel)
    xpUpdate(defaultXP)

end)

game.ReplicatedStorage.Buy.OnServerEvent:Connect(function(player,cost,item)
