Trying to make a data-saving system where it reads the children in a folder in the player then translates it into a dictionary and saves said dictionary. However, when I try to load it in it errors and says that the dictionary doesn’t exist.
Data loading:
local dataTableLoad = {}
local playerKey = "Player_"..ourPlayer.UserId
local success, errorMessage = pcall(function()
dataTableLoad = leaderStatStore:GetAsync(playerKey)
end)
if success then
for i, v in next, dataTableLoad do -- Errors here, Right now I just want it to print the variable name and the value
print(i)
print(v)
end
else
print(errorMessage)
end
Data saving:
local playerKey = "Player_"..ourPlayer.UserId
if ourPlayer:FindFirstChild("PetInventory") then
for i, v in pairs (ourPlayer.PetInventory:GetChildren())do
dataTableSave[v.Name] = v.Value
end
end
local success, errorMessage = pcall(function()
leaderStatStore:SetAsync(playerKey, dataTableSave)
end)
if success then
print("Data saving successful")
else
print("Not successful")
warn(errorMessage)
end
do not attempt to do that, anything that needs to be sent to a DataStore is internally turned into a string format, tables are JSONEncoded because Roblox’s DataStoreService interfaces with Dynamo DB, non-string formats are not acceptable for being stored.
JSONEncoding a table will essentially JSONEncode it twice, almost doubling the size.
@Carnibula you can’t load in data if it was never saved,
maybe try retrying if it didn’t save properly?
Try viewing retrieved data like this :
for k, v in pairs (dataTableLoad) do
print(k .." = "..v)
end
please use for i,v in pairs(array) do, and if it isn’t that means that the table is blank, which explains why you are loading nothing.
try looking at this, also is PetInventory just a thing full of things like StringValues?
if ourPlayer:FindFirstChild("PetInventory") then
for i, v in pairs (ourPlayer.PetInventory:GetChildren())do
print(I,v)
dataTableSave[v.Name] = v.Value
end
end
if ourPlayer:FindFirstChild("PetInventory") then
for i, v in pairs (ourPlayer.PetInventory:GetChildren())do
print(I,v)
dataTableSave[v.Name] = v.Value
end
end
So the code above does print back the strings inside PetInventory. (Yes pet inventory is full of string values).
Cool, so to make sure we’re on the same page before I bring this into studio, can you send the two functions here again? I’m going to try to figure this out real quick.
local dataStoreService = game:GetService("DataStoreService")
local leaderStatStore = dataStoreService:GetDataStore("test7")
local playerInGame = game.Players
local dataTableLoad
local dataTableSave = {}
playerInGame.PlayerAdded:Connect(function(ourPlayer)
--// L O A D I N G \\--
local playerKey = "Player_"..ourPlayer.UserId
local success, errorMessage = pcall(function()
dataTableLoad = leaderStatStore:GetAsync(playerKey) or {}
end)
if success then
print("Retrieving successful")
for i, v in pairs(dataTableLoad) do
print(i)
print(v)
end
else
print(errorMessage)
end
--[[
if success then
print("successful retrieving data")
local s, e = pcall(function()
for i, v in pairs(dataTableLoad) do
local newPet = Instance.new("StringValue")
newPet.Parent = ourPlayer:WaitForChild("PetInventory")
newPet.Value = v
newPet.Name = i
--v.Value = dataTableLoad[v.Name]
end
end)
else
print("No data, generating new data.")
warn(errorMessage)
end
--]]
end)
playerInGame.PlayerRemoving:Connect(function(ourPlayer)
--// S A V I N G \\--
local playerKey = "Player_"..ourPlayer.UserId
if ourPlayer:FindFirstChild("PetInventory") then
for i, v in pairs (ourPlayer.PetInventory:GetChildren())do
print(i,v)
dataTableSave[v.Name] = v.Value
end
end
local success, errorMessage = pcall(function()
leaderStatStore:SetAsync(playerKey, dataTableSave)
end)
if success then
print("Data saving successful")
else
print("Not successful")
warn(errorMessage)
end
end)
Try this, going to update this message with code changes.
local dataStoreService = game:GetService("DataStoreService")
local leaderStatStore = dataStoreService:GetDataStore("test7")
local playerInGame = game.Players
playerInGame.PlayerAdded:Connect(function(ourPlayer)
--// L O A D I N G \\--
local dataTableLoad = {};
local playerKey = "Player_"..ourPlayer.UserId
local success, errorMessage = pcall(function()
dataTableLoad = leaderStatStore:GetAsync(playerKey) or {}
end)
if success then
print("Retrieving successful")
for i, v in pairs(dataTableLoad) do
print(i)
print(v.name, v.value)
end
else
print(errorMessage)
end
--[[
if success then
print("successful retrieving data")
local s, e = pcall(function()
for i, v in pairs(dataTableLoad) do
local newPet = Instance.new("StringValue")
newPet.Parent = ourPlayer:WaitForChild("PetInventory")
newPet.Value = v
newPet.Name = i
--v.Value = dataTableLoad[v.Name]
end
end)
else
print("No data, generating new data.")
warn(errorMessage)
end
--]]
end)
playerInGame.PlayerRemoving:Connect(function(ourPlayer)
local dataTableSave = {}
--// S A V I N G \\--
local playerKey = "Player_"..ourPlayer.UserId
local toSave = {};
if ourPlayer:FindFirstChild("PetInventory") then
for i, v in pairs (ourPlayer.PetInventory:GetChildren())do
table.insert(toSave, {
name = v.Name,
value = v.Value
})
end
end
local success, errorMessage = pcall(function()
leaderStatStore:SetAsync(playerKey, dataTableSave)
end)
if success then
print("Data saving successful")
else
print("Not successful")
warn(errorMessage)
end
end)
I noticed an issue where you had your saving/loading varibles as global varibles, this means all players would get the previous players who left/joined items. You want them inside their respective functions.
