You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    I want to make the function run the countdown while running the script below.

  2. What is the issue? Include screenshots / videos if possible!
    The issue is the spawn function doesn’t work

  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    I am looking for solutions in DevForum.

function round.Start_Match(length)
	for i = length,0,-1 do
		round.Change_Info(to_MS(i))
		task.wait(1)
	end
	
	spawn(function()
		print("Hello world")
	end)
	
end

Thank you@!

This may or may not be an obvious question but is round.Start_Match being called?

Also, because you have the spawn under your for loop, it will not thread until the for loop is completed.

Try to use coroutines or task.spawn instead os just spawn

To get this effect, you’ll need to switch what’s in the spawn function. I recommend using task.spawn because it’s better


function round.Start_Match(length)

task.spawn(function()
	for i = length,0,-1 do
		round.Change_Info(to_MS(i))
		task.wait(1)
	end
end)

		print("Hello world")
	
end

The reason to this is because the loop will yield the code until it’s done, so you want to create a different thread to do that code while you can run other things at the same time.
