Roblox Studio - How To Handle Data #2 [DataStoreService]
This video will show you how to use DataStoreService to create the SaveData and LoadData function in a module script, we will also cover briefly about pcall, coroutine, PlayerRemoving and BindToClose functions.
How To Handle Data #1 can be found here: • Roblox Studio - How To Handle Data #1 [In-...
DataStoreModule module script:
local module = {}
local DataStoreService = game:GetService("DataStoreService")
local PlayerDS = DataStoreService:GetDataStore("PlayerDS")
local DataStoreKey = "SecretCode_"
local DataLoaded = {}
function module.LoadData(Player)
DataLoaded[Player.UserId] = false
local Data
local Success, ErrMsg
repeat
Success, ErrMsg = pcall(function()
Data = PlayerDS:GetAsync(DataStoreKey..Player.UserId)
end)
if not Success then
print("Failed to load player's data.")
end
until Success or game.Players:FindFirstChild(Player)
if Success then
Player.SavedData.Level.Value = Data["Level"] or 0
Player.SavedData.Exp.Value = Data["Exp"] or 0
Player.SavedData.Gold.Value = Data["Gold"] or 0
DataLoaded[Player.UserId] = true
end
end
function module.SaveData(Player)
if DataLoaded[Player.UserId] == false then
print("Data not loaded")
return false
end
local Success, ErrMsg
repeat
Success, ErrMsg = pcall(function()
PlayerDS:UpdateAsync(DataStoreKey..Player.UserId, function(oldValue)
local newValue = {}
newValue["Level"] = Player.SavedData.Level.Value
newValue["Exp"] = Player.SavedData.Exp.Value
newValue["Gold"] = Player.SavedData.Gold.Value
return newValue
end)
end)
if not Success then
print("Failed to save data.")
task.wait(6)

print("Data saved.")
end
