How do I create a self updating synced shop?

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    I want a shop that updates every 10 minutes, I just need something that can detect when it’s been 10 minutes so I can call a local function to update the shop, I need it to be synced across all servers.
  2. What is the issue? Include screenshots / videos if possible!
    I have looked all over the dev forum but there are only shops that update daily, nothing that updates every 10 minutes. I tried converting to update every 10 minutes but failed.
  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    I have tried everything available on the developer hub, I just can’t figure out how to make it every ten minutes.

This is my current code

local function toHMS(s) -- Just a function for time formatting
	return string.format("%02i:%02i:%02i", s/60^2, s/60%60, s%60)
end

function getAvailableItems(day)
	local rng = Random.new(day) 
	local shopItems
	local item = items[rng:NextInteger(1, #items)]
	shopItems = item
	return shopItems
end



local shopupdater = coroutine.create(function()
	while wait(1) do
		local day = math.floor(((timemodule.time() + offset) / (60 * 60 * 24))/600)
		local t = (math.floor(timemodule.time())) + offset -- Sets the date to Thursday 5PM PST
		local origtime = t - offset
		local daypass = origtime % 86400
		local timeleft = 86400 - daypass
		local timeleftstring = toHMS(timeleft)
		
		print(day)
		
		local stringy = "New trail in: ".. timeleftstring -- Optional printout, obviously I'd use "timeleftstring" for a countdown timer in a shop
		game.ReplicatedStorage.Events.CurrentTrailTime:FireAllClients(stringy)
		
		if day ~= currentDay then
			currentDay = day
			currentShopItems = getAvailableItems(day)
			game.ReplicatedStorage.Events.CurrentTrail:FireAllClients(currentShopItems)
			currenttrail = currentShopItems
			print('Updated shop items')		
		end
	end
end)
coroutine.resume(shopupdater)

You could just do a wait(600) to avoid extra code.

#4

You could use modulo operation to do this.

An example usage would be something like this

local StartTime = tick()
local Interval = 10 * 60 -- 10 Minutes

while wait(1) do
    local TimePassed = math.floor(tick - StartTime) -- Finds the amount of seconds passed since the start of this script

    if TimePassed % Interval == 0 then
        print("10 minutes has passed") -- Here you can put whatever you want to happen every 10 minutes
    end
end
#5

So if you want every server to update in 10 minute at exactly the same time you can do:


while wait(1) do
    local timeString = os.date("%X", os.time())
    local tkns = string.split(timeString, ":")
    if tkns[2] % 10 == 0 then
        --- update shop
        wait(60) -- wait to avoid updating again on same minute or create a variable to keep track of when shop was last updated

    end
end

that doesnt update across servers

Here is a discussion that helped me out when I was making something just like you are:

I saw this but couldn’t figure out how to convert it into every 10 minutes.

does this update across servers?

You could do that easily by making a predefined start time.
