How to constantly check a variable while in a loop and restart the loop if the check succeeds

Help and Feedback Scripting Support

I’m trying to make a system where if suddenly a player leaves during this while wait() do statement, the loop will reset.

I’m using a PlayerRemoving function for this since I don’t know how I can infinitely check every second inside the while wait() do loop (but if you do that could help solve this)

Any help is appreciated!

local currentCount = #game.Players:GetChildren()

while wait(1) do
     if #game.Players:GetChildren() >= currentCount then
        -- do whatever it is you wanna do
     end
end

I dont understand reseting this loop because while wait(1) do never ends, so doesnt need reset

#4

This only checks once through the entire loop. I need something that infinitely checks through the loop and when the check actually happens, It will restart the loop.

#5

You can use break inside a loop to stop it.

#6

Completely not the topic, dude. I know how to restart a loop BUT I want to do it with an infinitely checking line of code inside the while wait() do…

#7

Dude, clearify your problems better. Once again, while wait(1) do is infinite, so whatever you write inside it it checks infinitely. You cant restart it, because it doesnt have an ending

#8

Then how would I stop the code and take it back from the top.

#9

You can put your loop inside a function, and when you wanna restart it, break the loop and call the function again (You can call a function inside the same function thus creating sort of an artificial loop)

#10

Can I get an example of how I would do that?

#11

Sure

local loopBool = true
local function repLoop()
 loopBool = true
 while loopBool == true do
    wait(1)
     if #game.Players:GetChildren() < currentCount then
        loopBool = false
       repLoop()
     end
 end
end

repLoop()
#12

In this case “Break” wouldnt work because whatever you write after a break, doesnt get executed, so i used a bool

oh and make sure to add wait(1) inside your loop or it will be extremely heavy on performance

#13

Just tested the built-in function continue in game and it’s resetting my original loop back from the top already.

(Printed 2-5 then restarted the loop at continue)

So now, were back to how I can infinitely check a variable inside the loop WITHOUT roblox events I guess since they don’t allow loop based functions inside the code. So how can I constantly check?

#15

Have you tried this? It check the same thing you wanna check just without an event

#16

But does it constantly check while the loop is in the middle of running?

#17

use

repeat wait() until -- thing happens
#18 
while task.wait(1) do
	repeat task.wait(1) until #game.Players:GetPlayers() >= 2
	
	game.Players.PlayerRemoving:Wait()
	if #game.Players:GetPlayers() < 2 then
		continue
	end

end
#19

This will stun the code if I put it inside the loop.

This will also stun the code when there will be other code below the code checking if the players suddenly change.
