Lua roblox中的数据问题

不幸的是，我正试图在roblox中保存数据。它坏了，你能帮我吗？ 这是我的密码：

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

game.Players.PlayerAdded:Connect(function(player)
    local leaderstats = Instance.new("Model")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player

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

    local coins = Instance.new("IntValue")
    coins.Name = "Coins"
    coins.Parent = leaderstats
    coins.Value = ds:GetAsync(player.UserId.."-coins") or 0
    ds:SetAsync(player.UserId.."-coins", coins.Value)
    coins.Changed:Connect(function()
        ds:SetAsync(player.UserId.."-coins", coins.Value)
    end)

    local gems = Instance.new("IntValue")
    gems.Name = "Gems"
    gems.Parent = leaderstats
    gems.Value = ds:GetAsync(player.UserId.."-gems") or 0
    ds:SetAsync(player.UserId.."-gems", gems.Value)
    gems.Changed:Connect(function()
        ds:SetAsync(player.UserId.."-gems", gems.Value)
    end)

    local level = Instance.new("IntValue")
    level.Name = "Level"
    level.Parent = leaderstats
    level.Value = ds:GetAsync(player.UserId.."-level") or 1
    ds:SetAsync(player.UserId.."-level", level.Value)
    level.Changed:Connect(function()
        ds:SetAsync(player.UserId.."-level", level.Value)
    end)

    local xp = Instance.new("IntValue")
    xp.Name = "XP"
    xp.Parent = hidden
    xp.Value = ds:GetAsync(player.UserId.."-xp") or 0
    ds:SetAsync(player.UserId.."-xp", xp.Value)
    xp.Changed:Connect(function()
        ds:SetAsync(player.UserId.."-xp", xp.Value)
    end)

    local maxstamina = Instance.new("IntValue")
    maxstamina.Name = "MaxStamina"
    maxstamina.Parent = hidden
    maxstamina.Value = ds:GetAsync(player.UserId.."-maxstamina") or 100
    ds:SetAsync(player.UserId.."-maxstamina", maxstamina.Value)
    maxstamina.Changed:Connect(function()
        ds:SetAsync(player.UserId.."-maxstamina", maxstamina.Value)
    end)

    local maxmagic = Instance.new("IntValue")
    maxmagic.Name = "MaxMagic"
    maxmagic.Parent = hidden
    maxmagic.Value = ds:GetAsync(player.UserId.."-maxmagic") or 100
    ds:SetAsync(player.UserId.."-maxmagic", maxmagic.Value)
    maxmagic.Changed:Connect(function()
        ds:SetAsync(player.UserId.."-maxmagic", maxmagic.Value)
    end)

    local stamina = Instance.new("IntValue")
    stamina.Name = "Stamina"
    stamina.Parent = hidden
    stamina.Value = maxstamina.value

    local magic = Instance.new("IntValue")
    magic.Name = "Magic"
    magic.Parent = hidden
    magic.Value = maxmagic.value

end)

game.Players.PlayerRemoving:Connect(function(player)
    ds:setAsync(player.UserId.."-coins", player.leaderstats.Coins.Value)
    ds:setAsync(player.UserId.."-gems", player.leaderstats.Gems.Value)
    ds:setAsync(player.UserId.."-xp", player.hidden.XP.Value)
    ds:setAsync(player.UserId.."-level", player.leaderstats.Level.Value)
    ds:setAsync(player.UserId.."-maxstamina", player.hidden.MaxStamina.Value)
    ds:setAsync(player.UserId.."-maxmagic", player.hidden.MaxMagic.Value)
end)    

谢谢你的帮助！ 也没有错误代码，只是测试时数据没有保存。 我已启用Studio对API服务的访问。

真的，我不知道发生了什么我花了几个小时寻找如何解决这个问题，但我没有找到它。

可能是你的游戏还没有发布，但你的代码中没有任何东西看起来会抛出语法错误，但它看起来确实不安全和浪费

对GetAsync和SetAsync的每次调用都是一个阻塞网络请求，有可能失败并引发错误。另外，您可以从服务器发送一个数据包，如果达到该限制，您的代码将抛出错误并可能丢失玩家数据

您可以将整个值表保存到单个键中，而不是每个键保存一个值。这大大减少了网络请求的数量和失败的可能性

保存数据

加载数据

我想roblox社区会更有帮助。你发布了你的游戏吗？是的，我发布了它。我有一个错误：HTTP服务不是DataModel的有效成员。@Kylaaa我该怎么办？现在它说无法转换std:：string的值。我查了一下，上面说我的数据没有被编码。我应该怎么做才能修复它？我已经用额外的日志和安全检查更新了答案。希望这会给出一个关于正在发生的事情的更清晰的信息。现在它将同样的错误信息放在了警告中。我该怎么办？警告的全文是什么？警告应该向您显示它试图解析为JSON的内容。可能是字符串不是有效的JSON，或者存在其他问题。
