DataStore2: How to access the datastore in other scripts

pobammer · January 31, 2020, 8:13pm

Can you send me that script? I can show you how it’s done.

local DataStore2 = require(game.ServerScriptService.DataStore2)
local MainKey = "MainDataStore"
--DataStore2.Combine(MainKey, "Stats", "OtherStats")
local dataStore = DataStore2.Combine("MainDataStore", "Stage", "Rebirths", "Cash", "BetaTester", "Time")

game.Players.PlayerAdded:Connect(function(player)	
	local stageData = DataStore2("Stage",player)
	local rebirthsData = DataStore2("Rebirths",player)
	local cashData = DataStore2("Cash",player)
	local betaTesterData = DataStore2("BetaTester",player)
	local timeData = DataStore2("Time",player)
	
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	
	local otherStats = Instance.new("Folder")
	otherStats.Name = "OtherStats"
	
	local stages = Instance.new("IntValue")
	stages.Name = "Stage"
	stages.Value = stageData:Get(0)
	stages.Parent = leaderstats
	
	local rebirths = Instance.new("IntValue")
	rebirths.Name = "Rebirths"
	rebirths.Value = rebirthsData:Get(0)
	rebirths.Parent = leaderstats 
	
	local cash = Instance.new("IntValue")
	cash.Name = "Cash"
	cash.Value = cashData:Get(10)
	cash.Parent = leaderstats
	
	local betaTest = Instance.new("BoolValue")
	betaTest.Name = "BetaTester"
	betaTest.Value = betaTesterData:Get(true)
	betaTest.Parent = otherStats
	
	local timePlaying = Instance.new("IntValue")
	timePlaying.Name = "Time"
	timePlaying.Value = timeData:Get(0)
	timePlaying.Parent = otherStats
	
	leaderstats.Parent = player
	otherStats.Parent = player
	
	cashData:OnUpdate(function(newDataCash)
		player.leaderstats.Cash.Value = newDataCash
	end)
end)

local DataStore2 = require(game.ServerScriptService.DataStore2)
local MainKey = "MainDataStore"
DataStore2.Combine("MainDataStore", "Stage", "Rebirths", "Cash", "BetaTester", "Time")

game.Players.PlayerAdded:Connect(function(player)

	otherStats.Parent = player
	
	cashData:OnUpdate(function(newDataCash)
		print("cashData has been updated!")
		cash.Value = newDataCash
	end)
end)

local Players = game:GetService("Players")
local DataStore2 = require(game.ServerScriptService.DataStore2)

wait(10)

for _, Player in ipairs(Players:GetPlayers()) do
	local CashData = DataStore2("Cash", Player)
	CashData:Increment(10)
end

Change the script you sent me to the one on top, and make another script for testing with the code from the second example. Tell me if it updates.

Wizertex · January 31, 2020, 8:20pm

The second script should be in a loop?

pobammer · January 31, 2020, 8:23pm

Don’t loop it yet. This is just for testing.

Wizertex · January 31, 2020, 8:24pm

You are a legend! Working! Thank you so much. How should I put it in a loop now?

pobammer · January 31, 2020, 8:28pm

Well first, remove the print from :OnUpdate, and second, you can try this.

local Players = game:GetService("Players")
local DataStore2 = require(game.ServerScriptService.DataStore2)

local WAIT_TIME = 1 -- The time between each payout.
local INCREMENT_AMOUNT = 10 -- How much they are awarded.

while true do
	wait(WAIT_TIME)
	for _, Player in ipairs(Players:GetPlayers()) do
		local CashData = DataStore2("Cash", Player)
		CashData:Increment(INCREMENT_AMOUNT)
	end
end

Wizertex · January 31, 2020, 8:31pm

Seems to be working fine!
For time script, I will do the same.
For Rebirths, I will also do an event on click.
For stages, which increase when you touch them.
Should I put that function in all stages? And if so, I wouldn’t use increment but set so it’s always 100% which stage will be set.
Is there also another way to do it, not in each stage?

EDIT: I’ll actually put it in each stage.

pobammer · January 31, 2020, 8:44pm

That would work.
Also works.
For stages, if they’re like an obby stage, do something like the script below.
You can use CollectionService and the Tag Editor plugin.

local Players = game:GetService("Players")
local ServerScriptService = game:GetService("ServerScriptService")
local CollectionService = game:GetService("CollectionService")
local DataStore2 = require(ServerScriptService.DataStore2)

local function TouchedFenv(StageObject)
	local Stage
	local StageNameIsStage = tonumber(StageObject.Name)
	if StageNameIsStage then
		Stage = StageNameIsStage
	else
		-- Stage is a IntValue or something.
		if StageObject:FindFirstChild("Stage") then
			Stage = StageObject.Stage.Value
		end
	end

	if type(Stage) ~= "number" then
		warn("No stage, cannot setup properly.")
		return function() end
	else
		return function(Hit)
			local Character = Hit:FindFirstAncestorOfClass("Model")
			if Character then
				local Humanoid = Character:FindFirstChildOfClass("Humanoid")
				if Humanoid and Humanoid.Health > 0 then
					local Player = Players:GetPlayerFromCharacter(Character)
					if Player then
						local StageStore = DataStore2("Stage", Player)
						StageStore:Set(Stage) -- Make sure you setup :OnUpdate!
					end
				end
			end
		end
	end
end

for _, StageObject in ipairs(CollectionService:GetTagged("Stages")) do
	StageObject.Touched:Connect(TouchedFenv(StageObject))
end

Wizertex · January 31, 2020, 8:46pm

Should that be in each stage in game because I already have some script that changes stage anyway? I just need to add like 4 lines of code to change data value and will use Set instead of Increment

pobammer · January 31, 2020, 8:48pm

You can just do something like

local Players = game:GetService("Players")
local ServerScriptService = game:GetService("ServerScriptService")
local DataStore2 = require(ServerScriptService.DataStore2)

local STAGE_VALUE = 1

local function Touched(Hit)
	local Character = Hit:FindFirstAncestorOfClass("Model")
	if Character then
		local Humanoid = Character:FindFirstChildOfClass("Humanoid")
		if Humanoid and Humanoid.Health > 0 then
			local Player = Players:GetPlayerFromCharacter(Character)
			if Player then
				local StageStore = DataStore2("Stage", Player)
				StageStore:Set(STAGE_VALUE) -- Make sure you setup :OnUpdate!
			end
		end
	end
end

script.Parent.Touched:Connect(Touched)

Wizertex · January 31, 2020, 8:50pm

I have something similar to that. It also checks that player isn’t already above that stage.

Wizertex · January 31, 2020, 9:01pm

Also, does PlayerAdded event works for each player separately?
And how would I change value manually? Basically, in Explorer or in-game with admin.

pobammer · January 31, 2020, 9:15pm

What do you mean?

You have to require the DataStore2 module in the command line (be it in Studio’s or the in-game one) and you could increment it there, but I’m not sure.

Wizertex · January 31, 2020, 9:16pm

I mean, each PlayerAdded event is like spawn() event?

pobammer · January 31, 2020, 9:18pm

It should fire for every player that joins, unless it has a bunch of code that yields before it gets to the connecting part.

Wizertex · January 31, 2020, 9:19pm

Yeah xD, but it has core and runs for each player separately during whole game?

Wizertex · January 31, 2020, 9:21pm

I just realized I lost some piece of data
I don’t know why. Maybe beacuse I’m testing in Studio?
Wait, it doesn’t save anymore…

EDIT: Seems to be fine in game I guess.

Wizertex · January 31, 2020, 10:10pm

Do you know how would I make save all data (like autosave)?
Would this be ok:

while true do
      DataStore2:SaveAll(player)
      wait(120)
end

What about something less than 120, like 30 (I heard anything below 100 seconds isn’t good…)

pobammer · January 31, 2020, 10:36pm

You do not need to do that. Just trust DataStore2 completely. It will do its job.
