When the player plays the MinutesPlayed goes up like usual. But when the player rejoins, their saved number appears on the leaderboard but, then the Minutes played number goes down to 1 instead of adding 1. Sorry for the bad explanation.
Time Added Script:
Datastore:
Game Link: Emote Hangout - Roblox
That’s a lot of code. First question: Do you want everyone to see someone’s played minutes? If yes, let’s start then.
First create a Script in ServerSriptService. Let’s call it ‘TimeSpendOnPlaying’. For the code write this:
local DataStoreService = game:GetService("DataStoreService")
local MinutesPlayedDataStore = DataStoreService:GetDataStore("MinutesPlayed")
game.Players.PlayerAdded:Connect(function(player)
local leaderstats = Instance.new("Folder")
leaderstats.Name = "leaderstats"
leaderstats.Parent = player
local MinutesPlayedInt = Instance.new("IntValue")
MinutesPlayedInt.Name = "Minutes Played"
MinutesPlayedInt.Parent = leaderstats
local data
local success, errormessage = pcall(function()
data = MinutesPlayedDataStore:GetAsync(player.UserId.."-minutes played")
end)
if success then
MinutesPlayedInt.Value = data
else
print("There was an error while getting "..player.Name.." data!")
warn(errormessage)
end
end)
game.Players.PlayerRemoving:Connect(function(player)
local success, errormessage = pcall(function()
MinutesPlayedDataStore:SetAsync(player.UserId.."-minutes played", player.leaderstats["Minutes Played"].Value)
end)
if success then
print(player.Name.." data saved!")
else
print("There was an error while saving "..player.Name.." data!")
warn(errormessage)
end
end)
Once you’re done let’s make a Script located in StarterGUI. Let’s name it ‘MinutesPlayed’ or anything that you want. In the script write this:
while true do
wait(60) --There's 60 seconds in one minute.
local player = script.Parent.Parent
player.leaderstats["Minutes Played"].Value = player.leaderstats["Minutes Played"].Value + 1
end
That’s everything that I can say. Was it helpful? If yes mark this as a Solution and give it a 
! Thanks!
