How to break out of a loop via a connection?

Help and Feedback Scripting Support

#1

  • I have a game with rounds.

  • I want to make it so as soon as the selected player leaves, the game would end.

  • it would not be very ideal if I use if statements to constantly check for the player leaving.

  • I thought of using a connection event like this:

players.PlayerLeaving:Connect(function(leavingPlayer)
    
     if leavingPlayer == selectedPlayer then
           break -- attempting to break the rounds *for loop*
     end
end)

  • And looks like I cant break a loop inside a function/connection event.

  • Any help would be greatly appreciated! :+1:

Use a variable so it send a variable true and make the look run only when the variable is false eg ‘while variable == false do…’ or you can create a new local connection = spawn(function() ‘round stuff’ end) and then check if the connection is running in ‘players.PlayerLeaving:Connect’ like this ‘if connection then’ connection:Disconnect(), i would have to see the other script to help you better

Well I don’t think the connection:Disconnect will work actually for this isntacne sorry just use the variable bool thing

#4

I want to end the loop as soon as the selected player leaves.
I think the while “variable == false do” will only check the statment every irretateion

  • dont understand htis part
#5

This is what he is trying to say:

local shouldBreak = false

players.PlayerLeaving:Connect(function(leavingPlayer)

	if leavingPlayer == selectedPlayer then
		shouldBreak = true
	end
end) 

while true do
	
	if shouldBreak == true then
		break
	end
	
end

No.
Sorry for the confusion, let me clear it up.

My code is like this:

for gameRound = maxGameRounds, 0, -1 do

     <game logic>
end
#7

You could still implement the same line of code, and it should work.

yeah but,
I would have to check that if statement all the time.

There are 70 lines, so i’d basically need 70 of them.

#9

Send me your whole code and let me check it out. I won’t steal it I promise lol

#10

oh sure.
sorry for the spaghetti though

for gameRound = maxGameRounds, 0, -1 do
      local x = gameRound
	updatePlayersAlive()
	task.wait(1)
	announce("The Questionare is making the question!")
	questionUI = giveQuestionUI(selectedPlayer)
	local hasDoneEvent = false
	local newQuestionText
		
			
	local event = eventsFolder.QuestionCalc.OnServerEvent:Once(function(player, questionText)
		if player == selectedPlayer then
			questionUI:Destroy()
			hasDoneEvent = true
			newQuestionText = questionText
		end
	end)
			
	delay(questionMakeTIme, function()
				
	        if not hasDoneEvent then
		        event:Disconnect()
	        	announce("The Questionare has failed to make the question!", 1)
					
	          end	
	end)
		
	repeat task.wait(.1) until event.Connected == false
	if hasDoneEvent then
	       local answer = calculateString(newQuestionText)
		EditTiles(newQuestionText)
		countDown("What is " ..  newQuestionText, answerTime)
		fallTiles(newQuestionText)
		announce("The correct answer was " .. tostring(answer) .."!",5 )
		EditTiles("25*2")
	end
			
	if questionUI then questionUI:Destroy() end
	updatePlayersAlive()
			
	f seePlayers(selectedPlayer) then -- returns true if the selected player isnt in the game
		break
	end
			
	if gameRound == 0 then
		for i,v in players:GetPlayers() do
			if v.Team == game:GetService('Teams').Player then
				v.leaderstats.Wins.Value += 1
			end
		end
			i = 1
			for i,v in players:GetPlayers() do
				v.Team = game:GetService('Teams').Spectator
				v.Character.PrimaryPart.Position = teleportsFolder["Lobby"..tostring(i)].Position
				if i == 1 then i = 2 elseif i== 2 then i = 3 else i =1 end -- yes.
				end
				announce("Game ended! The Answerers won!",4)

			end
		end-- The game round loop end

players.PlayerLeaving:Connect(function(leavingPlayer)
    
     if leavingPlayer == selectedPlayer then
           break -- attempting to break the rounds *for loop*
     end
end)

But break gives an error so i cut it out

Edit: I put it at the start of the loop

for gameRound = maxGameRounds, 0, -1 do 

     players.PlayerLeaving:Connect(function(leavingPlayer)
    
          if leavingPlayer == selectedPlayer then
                break -- attempting to break the rounds *for loop*
          end
     end) 
 
     <other stuff>
end
#13 
local stupidVariables = false
     players.PlayerLeaving:Connect(function(leavingPlayer)
    
          if leavingPlayer == selectedPlayer then
               stupidVariables = true
		-- break -- attempting to break the rounds *for loop*
          end
     end) 


for gameRound = maxGameRounds, 0, -1 do 


	if stupidVariables == true then
break
end	
 
end
#14

it would only check to break the loop each irretation…

i want to make the game end as soon as the player leaves.

ive also implemented my version of that

if seePlayers(selectedPlayer) then -- returns true if the selected player isnt in the game
	break
end
#15

As i said. I would probabbly have to used that if statment for all the lines?
So thats why im trying to break it from a connection event :slight_smile:

#16 
local stupidVariables = false
     players.PlayerLeaving:Connect(function(leavingPlayer)
    
          if leavingPlayer == selectedPlayer then
               stupidVariables = true
		-- break -- attempting to break the rounds *for loop*
          end
     end) 


for gameRound = maxGameRounds, 0, -1 do 


	if stupidVariables == true then
break
end	
 
end


-- game proggress functions ()

if stupid variable == true -> break 

end)
#17

sorry for the confusion but

isnt that the exact thing as before?

Look up coroutines, something like this is probably what you need.

local rounds = coroutine.wrap(function()
    --code for game round
end)()
Players.playerleaving:connect(function()
--leave logic if true then
coroutine.cancel(rounds)
end)

sorry for a late response but

i searched it up on the docs.
looks like I couldnt find “coroutine.cancel()”

Error when i used it

Code:


local myWrap = coroutine.create(function()
	while true do
		task.wait(.1)
	end
end)

coroutine.resume(myWrap)


task.wait(10)

coroutine.cancel(myWrap)

EDIT:
using coroutine.wrap

Hello!

A better idea would be using task!

here’s an example:

local mySpawn = task.spawn(function()
	while true do
		print("hi")
		task.wait(1)
	end
end)

task.spawn(mySpawn)

task.wait(10)

task.cancel(mySpawn)

P.S if this was a solution, please mark it as one! Help other people out by making them learn!
