So I am trying to make a rank system that saves your exp and rank, I’ve already made the ranks save, but I haven’t gotten the exp to save.
Script:
local DSS = game:GetService("DataStoreService")
local RankDS = DSS:GetDataStore("RankData")
game.Players.PlayerAdded:Connect(function(plr)
local leaderstats = Instance.new("Folder")
leaderstats.Name = "leaderstats"
leaderstats.Parent = plr
local levelValue = Instance.new("IntValue")
levelValue.Name = "Rank"
levelValue.Parent = leaderstats
local expValue = Instance.new("NumberValue")
expValue.Name = "expValue"
expValue.Parent = plr
local maxExp = Instance.new("NumberValue")
maxExp.Name = "maxExp"
maxExp.Parent = plr
local function LevelUp()
levelValue.Value += 1
expValue.Value = 0
maxExp.Value = 1000
end
local function GainExp(gain)
expValue.Value += gain
if expValue.Value > maxExp.Value then
LevelUp()
end
end
--Load data
local PlrId = plr.UserId
print("First ID var has been set.")
local data
local data2 = nil
local success, errormessage = pcall(function()
data = RankDS:GetAsync(PlrId)
end)
print("First pcall has been fired.")
if success then
print("Success = true!")
levelValue.Value = data
expValue.Value = data2
end
end)
--Save data
game.Players.PlayerRemoving:Connect(function(plr)
local PlrId = plr.UserId
local data = plr.leaderstats.Rank.Value
local data2 = plr.expValue.Value
print("Second variables has been set!")
local success, errormessage = pcall(function()
RankDS:SetAsync(PlrId,data,data2)
end)
print("Second pcall has been fired!")
if success then
print("Data has been saved successfully")
else
print("There has been an error")
warn(errormessage)
end
end)
I really have no idea on how to save multiple values in one script, so any help would be appreciated.
I’ve been recommending to people in your situation to save this information in a table. This allows you to save this data and any other stats that you may add in the future development of your game.
A module that makes this easier is DataStore2, you can easily save values and it does the table work for you.
ProfileService is a great alternative from what I hear, but I haven’t really looked into it.
I don’t really know anything about data stores, or how to put the information into a table, I learned about data stores 1-2 weeks ago, so could you show me on how to do this? Thank you. Do I just make the data variables hold a table?
Piggybacking off of this, here is a dynamic solution I’ve made for saving folders or singular values alike
DS2 Automatically saves data, so all you really need to do is tell it what to load and it handles the rest.
local DataStorage = {}
local DS2 = require(game.ServerScriptService.ExternalLib.Datastore2)
local keys = game.ReplicatedStorage.Configuration.Constants.DataKeys
local SaveDataKey = keys.PlayerDataKey.Value
local saveableData = game.ReplicatedStorage.Configuration.PlayerStats
DataStorage.init = function(player)
local stats = player.Stats
for _, item in ipairs(saveableData:GetChildren()) do
wait(1)
if not item:IsA("Folder") then -- If it's a data value
DS2.Combine(SaveDataKey, item.Name)
local store = DS2(item.Name, player)
local playerStat = stats:FindFirstChild(item.Name)
playerStat.Value = store:Get(item.Value)
playerStat.Changed:Connect(function(value)
store:Set(value)
end)
else -- if Folder..
local info = folderIndexTable[item.Name]
DS2.Combine(info.key, info.name)
local store = DS2(info.name, player)
local default = {}
local playerFolder = stats:FindFirstChild(item.Name)
for _, i in ipairs(item:GetChildren()) do
table.insert(default, i.Value)
end
local data = store:Get(default)
local objects = info.format(data)
playerFolder:ClearAllChildren()
for _, newItem in ipairs(objects) do
newItem.Parent = playerFolder
end
local function update(folder)
local new = {}
for _, i in ipairs(folder:GetChildren()) do
table.insert(new, i.Value)
end
store:Set(new)
end
playerFolder.ChildAdded:Connect(function(child)
update(playerFolder)
end)
playerFolder.ChildRemoved:Connect(function()
update(playerFolder)
end)
end
end
end
return DataStorage
It’s pretty simple, you just need to put a table into SetAsync’s 2nd argument.
local DSS = game:GetService("DataStoreService")
local RankDS = DSS:GetDataStore("RankData")
game.Players.PlayerAdded:Connect(function(plr)
local leaderstats = Instance.new("Folder")
leaderstats.Name = "leaderstats"
leaderstats.Parent = plr
local levelValue = Instance.new("IntValue")
levelValue.Name = "Rank"
levelValue.Parent = leaderstats
local expValue = Instance.new("NumberValue")
expValue.Name = "expValue"
expValue.Parent = plr
local maxExp = Instance.new("NumberValue")
maxExp.Name = "maxExp"
maxExp.Parent = plr
local function LevelUp()
levelValue.Value += 1
expValue.Value = 0
maxExp.Value = 1000
end
local function GainExp(gain)
expValue.Value += gain
if expValue.Value > maxExp.Value then
LevelUp()
end
end
--Load data
local PlrId = plr.UserId
print("First ID var has been set.")
local data
local success, errormessage = pcall(function()
data = RankDS:GetAsync(PlrId)
end)
print("First pcall has been fired.")
if success then
print("Success = true!")
levelValue.Value = data[1]
expValue.Value = data[2]
end
end)
--Save data
game.Players.PlayerRemoving:Connect(function(plr)
local PlrId = plr.UserId
local data = plr.leaderstats.Rank.Value
local data2 = plr.expValue.Value
print("Second variables has been set!")
local success, errormessage = pcall(function()
RankDS:SetAsync(PlrId, {data,data2})
end)
print("Second pcall has been fired!")
if success then
print("Data has been saved successfully")
else
print("There has been an error")
warn(errormessage)
end
end)
