How would I make everything in a folder happen at once?

local Alarms = game.Workspace.Alarms
local strobeimage = game.Workspace.Alarms.FireAlarm.Strobe.Flasher.Strobe
local strobelight = game.Workspace.Alarms.FireAlarm.Strobe.Light
local IsPlayingAlarms = false

function onMouseClick()
	if (IsPlayingAlarms) then return end -- Check if alarms are already playing.

	for i, FireAlarm in pairs(Alarms:GetChildren()) do
		coroutine.resume(coroutine.create(function() -- Thread the effects.
			FireAlarm.horn.Sound:Play() -- Sound the alarm.
			
			while (IsPlayingAlarms) -- Strobe effect until IsPlayingAlarms = false
				wait(1)
				strobeimage.Visible = true
				strobelight.Enabled = true
				wait(0.1)
				strobelight.Enabled = false
				strobeimage.Visible = false
		end

		
		FireAlarm.horn.Sound:Stop()
		strobelight.Enabled = false
		strobeimage.Visible = false
	end))
	end
	end

Yes?

Oh wait, I forgot the “do” haha.

while (IsPlayingAlarms) do

Sorry, I know multiple programming languages. Others don’t use “do”.

#23

It still seems to not be working, nothing seems to be working now…?

#24

Add print("Alarm running") under the the while (IsPlayingAlarms) do line. Check if it’s even running.

EDIT: Also, check if strobeimage is pointing to anything. Shouldn’t it be FireAlarm.Strobe.Flasher

#25 
while (IsPlayingAlarms) -- Strobe effect until IsPlayingAlarms = false
   wait(1)
   FireAlarm.Strobe.Flasher.Visible = true
   FireAlarm.Strobe.Light.Enabled = true
   wait(0.1)
   FireAlarm.Strobe.Flasher.Visible = false
   FireAlarm.Strobe.Light.Enabled = false
end

Remember to change them at the end of the coroutine as well.
