How do we lock a place after a player joined so nobody else can join?

Hi guys! So, I want to make a Camping game and I've already done the lobby and the teleportation, but I'm afraid that when a group of players has been teleported to the In-game story they join different servers and that some of them will join already running In-game servers.

Also, the In-game story server is a place in the game that the player can just see the lobby server's Icon in their home page, and not the In-game story server's Icon

So my question is that after that group of players in a car has been teleported, how do we let them join in the SAME In-game server?

Help will be REALLY REALLY appreciated!!!!

You can make a PlayerAdded event, and add a number to a variable, and if the variable has reached a certain amount, you can begin kicking players.

For example:

local playersRecorded = 0

game.Players.PlayerAdded:Connect(function(player)
	if playersRecorded == 5 then -- assume 5 players have joined
		player:Kick("Server-locked") -- kicks the player
	else
		playersRecorded = playersRecorded + 1 -- adds in a one to the recorded player amount
	end
end)

Or you can make one that automatically kicks players after a certain time period:

wait(3) -- assume players will have loaded by then, by waiting 3 seconds after server start up

game.Players.PlayerAdded:Connect(function(player)
	player:Kick("Server-locked")
end)
