Need help with making a system that keeps track of how many an item exists

[jvckie_yt (jvckie)]

Yeah, it was just broken at that time.

[daisytheghostchild98 (bcman)]

Use the previous code but change it up a bit to count only when a desired pet exists (the instances MUST be exact with this code):

local Items = 0
local ItemHolder = workspace
local Reference = workspace.Pet
while task.wait(1) do
   Items = 0
   for _, Item in pairs(ItemHolder:GetChildren()) do
      if Item == Reference then Items += 1 end
   end
end

Edit: If you want to go off names, use this code instead (doesnt have to be exact, but must have the same name):

local Items = 0
local ItemHolder = workspace
local Reference = workspace.Pet
while task.wait(1) do
   Items = 0
   for _, Item in pairs(ItemHolder:GetChildren()) do
      if Item.Name == Reference.Name then Items += 1 end
   end
end

Main Script: – Basically the datastore (Server Script)

local dss = game:GetService("DataStoreService")
local save = dss:GetDataStore("ExistsValue")


for i, ExistsValue in pairs(game.ReplicatedStorage.Pets_Folder:GetChildren()) do
	local Exists = ExistsValue:FindFirstChild("Exists")
	
	game:BindToClose(function()
		save:SetAsync("ExistsValue", Exists.Value)
	end)
	while wait(math.random(5, 10)) do
		save:SetAsync("ExistsValue", Exists.Value)
	end
	
	local saveddata = save:GetAsync("ExistsValue", Exists.Value)
	Exists.Value = saveddata
	print(Exists.Value.." exists of "..ExistsValue)
end

The script that gets the number of how much a pet exists: - Local Script

local Index = script.Parent:WaitForChild("Index")
local InfoFrame = Index:WaitForChild("Info")
local PetImage = InfoFrame:WaitForChild("Image"):WaitForChild("PetImage")
local PetName = InfoFrame:WaitForChild("PetName")
local Description = InfoFrame:WaitForChild("Description")
local scrollingFrame = Index:WaitForChild("ScrollingFrame")
local template = scrollingFrame:WaitForChild("Template")
local Pets = RS:WaitForChild("Pets_Folder")
local Click = script.Parent:WaitForChild("Click")
local Difficulty = InfoFrame:WaitForChild("Difficulty")
local plr = game:GetService("Players").LocalPlayer
local Remote2 = game.ReplicatedStorage.GetPetExistsValue

local selectedTemplate = nil

local function selectTemplate(temp)
	InfoFrame.Visible = true
	selectedTemplate = template
	PetImage.Image = temp.PetImage.Image
	PetName.Text = "Pet Name: "..temp.Name
	Description.Text = RS:FindFirstChild("Pets_Folder"):WaitForChild(temp.Name).Description.Value
	Difficulty.Difficulty.Text = "Difficulty: "..RS:FindFirstChild("Pets_Folder"):WaitForChild(temp.Name).Difficulty.Value
	InfoFrame.Exists.Text = Remote2:InvokeServer(temp.Name).." Exists" --Here's where I get the number of how much of a pet exists
	if RS:FindFirstChild("Pets_Folder"):WaitForChild(temp.Name).Difficulty.Value == "Exclusive" then
		Difficulty.ExclusiveGradient.Enabled = true
		Difficulty.BackgroundTransparency = 0
	end
	if RS:FindFirstChild("Pets_Folder"):WaitForChild(temp.Name).Difficulty.Value ~= "Exclusive" then
		Difficulty.ExclusiveGradient.Enabled = false
		Difficulty.BackgroundTransparency = 1
	end
	
	
	local NoteTemplate = RS:FindFirstChild("Pets_Folder"):WaitForChild(temp.Name)
	
	if NoteTemplate:FindFirstChild("Note") then
		InfoFrame.Note.Visible = true
		InfoFrame.Note.Text = RS:FindFirstChild("Pets_Folder"):WaitForChild(temp.Name).Note.Value
	else
		InfoFrame.Note.Visible = false
		InfoFrame.Note.Text = "NaN"
	end
end

for i, v in pairs(Pets:GetChildren()) do
	local newTemplate = template:Clone()
	newTemplate.Name = v.Name
	newTemplate.Parent = scrollingFrame
	newTemplate.Visible = true
	
	newTemplate.PetImage.Image = v:WaitForChild("Image").Texture
	
	local Handler = RS:FindFirstChild("Pets_Folder"):FindFirstChild(newTemplate.Name)

	if Handler.Difficulty.Value == "Easy" then
		newTemplate.LayoutOrder = -7
	else
		if Handler.Difficulty.Value == "Medium" then
			newTemplate.LayoutOrder = -6
		else
			if Handler.Difficulty.Value == "Hard" then
				newTemplate.LayoutOrder = -5
			else
				if Handler.Difficulty.Value == "Insane" then
					newTemplate.LayoutOrder = -4
				else
					if Handler.Difficulty.Value == "Extreme" then
						newTemplate.LayoutOrder = -3
					else
						if Handler.Difficulty.Value == "Exclusive" then
							newTemplate.LayoutOrder = -2
						else
							if Handler.Difficulty.Value == "Event" then
								newTemplate.LayoutOrder = -1
						end
						end
					end
				end
			end
		end
	end
	
	
	newTemplate.MouseButton1Click:Connect(function()
		selectTemplate(newTemplate)
		Click:Play()
		scrollingFrame.Visible = false
	end)
end

The script used for the remote to get the number of how much a pet exists: - Server Script

local save = dss:GetDataStore("ExistsValue")
local rs2 = game:WaitForChild("ReplicatedStorage")

rs2:WaitForChild("GetPetExistsValue").OnServerInvoke = function(player, temp)
	if rs2:FindFirstChild("Pets_Folder"):WaitForChild(temp) then
		local ExistsValue = rs2["Pets_Folder"]:FindFirstChild(temp)
		local num = save:GetAsync("ExistsValue", ExistsValue)
		return num
	end
end

(this is what I tried doing, but it didn’t really work)

[daisytheghostchild98 (bcman)]

@jvckie_yt

for i, v in pairs(Pets:GetChildren()) do
	local newTemplate = template:Clone()
	newTemplate.Name = v.Name
	newTemplate.Parent = scrollingFrame
	newTemplate.Visible = true

In here to prevent replicas from showing, you can use this (using this code means add a TextLabel of some sort named Duplicates):

local alreadyHave = {}
for i, v in pairs(Pets:GetChildren()) do
	local duplicates = 0
	if not table.find(alreadyHave, v) then
		local newTemplate = template:Clone()
		newTemplate.Name = v.Name
		newTemplate.Parent = scrollingFrame
		newTemplate.Visible = true
		table.insert(alreadyHave, v)
		for _, pet in pairs(Pets:GetChildren()) do
			if pet == v then duplicates += 1 end
		end
	else continue end
	--code inbetween
	
	newTemplate.Duplicates.Text = duplicates
end

Edit: It’s fixed, hopefully.

You should read this post if you want a value to be the same on every single server of the game.

How do I sync/save a value across all servers in a game?

Hello! I’m trying to make a game where every time a player clicks a part, a number goes up by 1 (cooldown of 15 seconds). This number is shared so if 2 players click the part it becomes 2. What I want to aim for is this number being synced across all servers within the game, so if one player clicks the button, and in a different server 3 people click the button, 4 will show up as the number. I know that this can’t be achieved in real time, but I was hoping to get advice on how to make a system…

I assume this is what you need

[jvckie_yt (jvckie)]

Alright, thank you I will make sure to add that to my code.

[jvckie_yt (jvckie)]

Okay. I will also try that

Thank you!

[jvckie_yt (jvckie)]

[daisytheghostchild98 (bcman)]

Read my above post as I fix the issues with it. Sorry, my coding is mixed up today.

[jvckie_yt (jvckie)]

Alright. It’s okay lol, I understand

[daisytheghostchild98 (bcman)]

Ok, it should be fixed:

local alreadyHave = {}
for i, v in pairs(Pets:GetChildren()) do
	local duplicates = 0
	if not table.find(alreadyHave, v) then
		local newTemplate = template:Clone()
		newTemplate.Name = v.Name
		newTemplate.Parent = scrollingFrame
		newTemplate.Visible = true
		table.insert(alreadyHave, v)
		for _, pet in pairs(Pets:GetChildren()) do
			if pet == v then duplicates += 1 end
		end
	else continue end
	--code inbetween
	
	newTemplate.Duplicates.Text = duplicates
end

Edit: I proofread it and it should work when inserted. I hope it helps!

[jvckie_yt (jvckie)]

Error: Unknown Global ‘newTemplate’

[daisytheghostchild98 (bcman)]

Sorry, again. I forgot about that, here’s your fix:

local alreadyHave = {}
for i, v in pairs(Pets:GetChildren()) do
	local duplicates = 0
	local newTemplate
	if not table.find(alreadyHave, v) then
		newTemplate = template:Clone()
		newTemplate.Name = v.Name
		newTemplate.Parent = scrollingFrame
		newTemplate.Visible = true
		table.insert(alreadyHave, v)
		for _, pet in pairs(Pets:GetChildren()) do
			if pet == v then duplicates += 1 end
		end
	else continue end
	--code inbetween
	
	newTemplate.Duplicates.Text = duplicates
end

This is the kinda trial-and-error stuff my brain does when coding. (lol)

[jvckie_yt (jvckie)]

Thank you. I’ll try that. /////

[jvckie_yt (jvckie)]

(This post hasn’t been solved yet)

[clxr (Jason)]

Still no luck huh? Been looking around for a solution to this as well, and the only thing I can think of that could handle the traffic is an offsite database

[jvckie_yt (jvckie)]

Yeah. I was thinking of using datastores before but that wouldn’t work as well for sure.

[baukeblox12]

create your own api, update your values this way, dont update your database everytime a new item is found/unboxed since that will hit database rate limits quickly, instead, cache the amoutn of new found items, and deploy the new unboxed items changes every 10-20 seconds to your database

[baukeblox12]

if youre using python, you can use asynchronous api libraries that will allow you to run tasks for caching and updating these values

an API library (in my opinion the BEST api library), FastAPI allows for asynchronous api call handling
