I want to create a system similar to those of Pet Sim X, and other games where you can receive a code from a Dev, and then enter that into a GUI
My current code uses a RemoteEvent to send to the server where it uses a module script to check the available codes and then it removes it from the module script. The problem is I want it to be globally stored and whenever a user enters the code they receive the benefits and then the code is deleted on every server permanently
This is my code I have on the server script:
local CodesTable = require(script.ExclusiveCodesList)
game.ReplicatedStorage.CheckExclusiveCodes.OnServerEvent:Connect(function(Player,Text)
local avalible = CheckCode(Text)
game.ReplicatedStorage.ReturnCodeStatus:FireClient(Player, avalible)
if avalible == true then
print("CODE REEDEMED")
local positionInTable = table.find(CodesTable, Text)
table.remove(CodesTable, positionInTable)
-- Redeem Stuff Here
end
end)
function CheckCode(code)
for i, v in pairs(CodesTable) do
if v == code then
return true
end
end
end
You could store the code as a key in a DataStore, then when a player tries to redeem it, check if the key exists using GetAsync(), and if it does, redeem it and call RemoveAsync() on the key so it can’t be redeemed by anyone else.
I’ve got DataStores for all my other code (such as cash, xp and other stuff) but I’m not sure on how I would make it global or in which folder I should save the code or do I just keep it all on script without using physical string values?
Does DataStore allow the use of saving string values with spaces in it? As since I’ve got all my codes on a table I’m converting the table into a long string so,
No, I’m now just using for i, v in pairs loop to set the datastore:
local DataStore = game:GetService("DataStoreService"):GetDataStore("ExclusiveCodes")
for i, v in pairs(CodesTable) do
if DataStore:GetAsync(v) then else
print(v)
DataStore:SetAsync(v, true)
end
end
So my code works from server but whenever I leave it doesn’t save, I’m not sure if I need to use set Async when the player leaves or something else.
local DataStore = game:GetService("DataStoreService"):GetDataStore("ExclusiveCodes")
for i, v in pairs(CodesTable) do
if DataStore:GetAsync(v) then else
print(v)
DataStore:SetAsync(v, true)
end
end
game.ReplicatedStorage.CheckExclusiveCodes.OnServerEvent:Connect(function(Player,Text)
local avalible = CheckCode(Text)
game.ReplicatedStorage.ReturnCodeStatus:FireClient(Player, avalible)
if avalible == true then
print("CODE REEDEMED")
DataStore:SetAsync(Text, false)
-- Redeem Stuff Here
end
end)
So I’ve tried multiple solutions and this is where my code has gotten up to:
local CodesTable = require(script.ExclusiveCodesList)
local DataStore = game:GetService("DataStoreService"):GetDataStore("ExclusiveCodes")
local SaveData = {}
for i, v in pairs(CodesTable) do
local data = DataStore:GetAsync("ExclusiveCodes")
print(data[v])
if not data[v] then
SaveData[v] = true
else
SaveData[v] = data[v]
end
print(data[v])
end
DataStore:SetAsync("ExclusiveCodes", SaveData)
game.ReplicatedStorage.CheckExclusiveCodes.OnServerEvent:Connect(function(Player,Text)
local avalible = CheckCode(Text)
game.ReplicatedStorage.ReturnCodeStatus:FireClient(Player, avalible)
if avalible == true then
print(SaveData)
SaveData[Text] = false
print(SaveData[Text])
local success = nil
local errorMsg = nil
local attempt = 1
repeat
success, errorMsg = pcall(function()
DataStore:SetAsync("ExclusiveCodes", SaveData)
end)
attempt += 1
if not success then
warn(errorMsg)
task.wait(3)
end
until success or attempt == 5
print(DataStore:GetAsync("ExclusiveCodes"))
-- Redeem Stuff Here
end
end)
function CheckCode(code)
local data = DataStore:GetAsync("ExclusiveCodes")
if data[code] then
return true
else
return false
end
end
It all works when in the same server but when I leave and rejoin the DataStore doesn’t work and you can keep redeeming the codes.
for i, v in pairs(CodesTable) do
if DataStore:GetAsync(v) == nil then
DataStore:SetAsync(v, true)
end
end
your old check would overwrite if the value is false, if its TRUE (boolean) then do nothing else, reset the code to true. the snippet i put above only calls setasync if the code is nil in the datastore
