Is there a way to detect if someone leaves/joins within one function?

I know that you can do game.Players.Playeradded to detect when someone joins
and I also know that you can do game.Players.PlayerRemoving to detect when someone leaves

but is there a way to detect whenever someone leaves/joins within one function?
I’m trying to figure this out for a player counter I have
It updates when someone joins but the number doesn’t go down because there’s nothing to tell it to

You could just connect PlayerAdded and PlayerRemoving to the same function?

Something like this:

local function foo(player)

-- blah blah blah

end

game.Players.PlayerAdded:Connect(foo)

game.Players.PlayerRemoving:Connect(foo)

is there a way to do this in the way I format my functions?

That would be pretty useless

What exactly is the problem? Just connect a PlayerRemoving event and change the “count” variable

#5 
local number = 0

game.Players.PlayerAdded:Connect(function(player)
     number += 1    
end)

game.Players.PlayerRemoving:Connect(function(player)
     number -= 1
end)

Unfortunately not that I know of.

Alright, I made this script real fast, tell me if there is a error:

local gui = script.Parent
local children = game:GetService("Players"):GetChildren()
local plr = game:GetService("Players") -- add a .LocalPlayer if it's a local script


local count = #children

local function pro(number)
if plr then
count += number
gui.Text = count
elseif not plr then
count -= number
gui.Text = count
end

game.Players.PlayerAdded:Connect(pro,1)

game.Players.PlayerRemoved:Connect(pro, 1)

Firstly that script would not work (and doesn’t make sense)

Secondly that’s overly complicated.

You should follow the Single-Responsibility-Principle and have each function do one thing (avoid boolean parameters that change functionality)

-- server script
local player_count = 0

game.Players.PlayerAdded:Connect(function(player)
     player_count += 1
     -- you can update players ui via remote or something here
end)

game.Players.PlayerRemoving:Connect(function(player)
     player_count -= 1
     -- you can update players ui via remote something here
end)

I don’t know maybe something like this :


--Server Script

local RE = Instance.new("RemoteEvent")
RE.Name = "PlayerCount"
RE.Parent = game.ReplicatedStorage

local playerLeft = 0
game.Players.PlayerAdded:Connect(function(player)
	playerLeft = playerLeft + 1
	RE:FireAllClients(playerLeft)
end)
game.Players.PlayerRemoving:Connect(function(player)
	playerLeft = playerLeft - 1
	RE:FireAllClients(playerLeft)
end)

--Client Script
wait(3)
local gui = script.Parent
local RE = game.ReplicatedStorage.PlayerCount
RE.OnClientEvent:Connect(function(count)
	gui.Text = count
end)

you guys all overcomplicated this, this is as simple as the an answer that I needed
I didn’t need feedback on how terrible a newbies scripting may be
