How to create servers and join them?

Well this would be a good time to use firebase realtime database. Well first of all we need some sort of poller which constantly does get request from firebase. Then we need a thing where when a server is created it’s JOBID get’s added to the firebase parent node. Lastly when BindToClose is called on a server which is reserved we need it to be removed from the parent node in firebase.

local RunService = game:GetService("RunService")
local GameInfo = require(game.ServerScriptService.Modules.GameInfo)

local IsStudio = RunService:IsStudio()

function SetServer(Value)
	GameInfo.Firebase.ServerList:UpdateAsync("Servers", function(OldData)
		if type(OldData) ~= 'table' then
			OldData = {}
		end
		
		OldData[game.JobId] = Value
		return OldData 
	end)
end

if IsStudio == true then -- studio server doesn't have a JOBID
	print 'studio doesnt worl'
else
	print(game.JobId, "     this is the ID")
	SetServer(true)
end



game:BindToClose(function()
	if IsStudio == true then
		print 'p'
	else
		-- you have to remove the node from "servers'
		GameInfo.Firebase.ServerList:DeleteAsync("Servers/".. game.JobId)
	end
end)

while true do -- poller
	local Data = GameInfo.Firebase.ServerList:GetAsync("Servers")


	
	for ServerName,PlaceHolderValue in pairs(Data) do
		print(ServerName)
	end
	
	wait(30) -- 30 second server update rate
end

Firebase limits for the free plan.

ANYWAYS Good thing universe scripts and temporary datastores are coming, then we can do this without the 50,000 read limit in firebase for the free plan. Sure you can buy the paid plan if you want though.

When universe scripts come this will be practical until now we’ll have to rely on buying other databases and using it. (50,000 read limit isn’t big enough for big games), that’s why we need the paid plan.

BUT YOU CAN MAKE A JOIN PERSON SYSTEM, THAT IS PRACTICAL TO DO.
