How to stop a function while its running?

How to stop a function while its running?? I'm looking how to stop it from outside the function. Using return or break will stop from within the function, which is not what I'm really looking for.

Any help would be appreciated. Thanks in Advance!!

setfenv(func,{})

What you can probably do if its a while true loop or some other loop is check if a value you defined earlier is false or true

For example:

local Check = false

coroutine.wrap(function()
	while Check == false do
		print("Running")
		wait(0.1)
	end
end)()

wait(5)

Check = true -- This will make the function stop running

You could also use the same logic for a function you have defined:

local Check = false

function GoodFunction()
	coroutine.wrap(function()
		if Check == false then
			repeat
				print("Good")
				wait(0.1)
			until Check == true
		end
	end)()
end

GoodFunction()

wait(5)

Check = true

Let me know if you have any issues!
