如何为超过 3 个统计数据的排行榜制作保存系统

Question

我想做一个存档系统，这样大家玩的时候就不用每次都重启

我真的不知道该怎么做，所以我会向您展示我的领导者统计数据的代码，该代码位于作品 space

local function onPlayerJoin(player)
    local leaderstats = Instance.new("Model")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player


    local gold = Instance.new("IntValue")
    gold.Name = "JumpBoost"
    gold.Value = 150
    gold.Parent = leaderstats

        local speed = Instance.new("IntValue")
    speed.Name = "Speed"
    speed.Value = 20
    speed.Parent = leaderstats

    local coin = Instance.new("IntValue")
    coin.Name = "CloudCoins"
    coin.Value = 0
    coin.Parent = leaderstats

    local rebirths = Instance.new("IntValue")
    rebirths.Name = "Rebirths"
    rebirths.Value = 0
    rebirths.Parent = leaderstats

end


game.Players.PlayerAdded:Connect(onPlayerJoin)

我又不知道该怎么做了，请帮忙。

这是一篇关于数据存储的更好的文章:(https://developer.roblox.com/articles/Data-store)。测试的重要警告：DataStoreService cannot be used in Studio if a game is not configured to allow access to API services. 因此您必须发布游戏并在线配置它以允许您发出 HTTP 请求和访问数据存储 API。因此，请务必查看 link 中标题为：Using Data Stores in Studio. 的部分，它将引导您浏览菜单。

总之...

现在，您正在创建玩家加入游戏时的起始值。 DataStores 允许您保存上次 session 的值，然后在下次他们加入时加载这些值。

Roblox DataStores 允许您存储 key-value 表。让我们创建一个助手 object 来管理数据的加载和保存。

制作一个名为 PlayerDataStore 的模块脚本：

 -- Make a database called PlayerExperience, we will store all of our data here
 local DataStoreService = game:GetService("DataStoreService")
 local playerStore = DataStoreService:GetDataStore("PlayerExperience")

 local defaultData = {
    gold = 150,
    speed = 0,
    coins = 0,
    rebirths = 0,
}
local PlayerDataStore = {}

function PlayerDataStore.getDataForPlayer(player)
    -- attempt to get the data for a player
    local playerData
    local success, err = pcall(function()
        playerData = playerStore:GetAsync(player.UserId)
    end)

    -- if it fails, there are two possibilities:
    --  a) the player has never played before
    --  b) the network request failed for some reason
    -- either way, give them the default data
    if not success or not playerData then
        print("Failed to fetch data for ", player.Name, " with error ", err)
        playerData = defaultData
    else
        print("Found data : ", playerData)
    end

    -- give the data back to the caller
    return playerData
end

function PlayerDataStore.saveDataForPlayer(player, saveData)
    -- since this call is asyncronous, it's possible that it could fail, so pcall it
    local success, err = pcall(function()
        -- use the player's UserId as the key to store data
        playerStore:SetAsync(player.UserId, saveData)
    end)
    if not success then
       print("Something went wrong, losing player data...")
       print(err)
    end
end


return PlayerDataStore

现在我们可以使用这个模块来处理我们所有的加载和保存。

在一天结束时，您的玩家加入代码看起来与您的示例非常相似，它只会尝试首先加载数据。监听玩家何时离开也很重要，这样您就可以保存他们的数据以供下次使用。

在 PlayerDataStore 旁边的脚本中：

-- load in the PlayerDataStore module
local playerDataStore = require(script.Parent.PlayerDataStore)


local function onPlayerJoin(player)
    -- get the player's information from the data store,
    --  and use it to initialize the leaderstats
    local loadedData = playerDataStore.getDataForPlayer(player)

    -- make the leaderboard
    local leaderstats = Instance.new("Model")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player

    local gold = Instance.new("IntValue")
    gold.Name = "JumpBoost"
    gold.Value = loadedData.gold
    gold.Parent = leaderstats

    local speed = Instance.new("IntValue")
    speed.Name = "Speed"
    speed.Value = loadedData.speed
    speed.Parent = leaderstats

    local coin = Instance.new("IntValue")
    coin.Name = "CloudCoins"
    coin.Value = loadedData.coins
    coin.Parent = leaderstats

    local rebirths = Instance.new("IntValue")
    rebirths.Name = "Rebirths"
    rebirths.Value = loadedData.rebirths
    rebirths.Parent = leaderstats
end

local function onPlayerExit(player)
    -- when a player leaves, save their data
    local playerStats = player:FindFirstChild("leaderstats")
    local saveData = {
        gold = playerStats.JumpBoost.Value,
        speed = playerStats.Speed.Value,
        coins = playerStats.CloudCoins.Value,
        rebirths = playerStats.Rebirths.Value,
    }
    playerDataStore.saveDataForPlayer(player, saveData)
end


game.Players.PlayerAdded:Connect(onPlayerJoin)
game.Players.PlayerRemoving:Connect(onPlayerExit)

希望对您有所帮助！
