3 seconds to make input

cant get this code to work for two days XD

its about to press any key during 3 secs or the timer fires:

print("KEY OR WAIT")
while true do
local event, arg1 = os.pullEvent()
local timerID = os.startTimer(3)
if event == "timer" and arg1 == timerID then
print("My timer was first!")
return
end
if event == "key" then
print("Key was first")
return
end
end

k input works fine but timer does not fire .Can anyone help?

You have to start the timer before pulling the event.

Also, if the call to os.startTimer is in the loop, the timer will get reset each time it pulls an event.

print("KEY OR WAIT")
local timerID = os.startTimer(3)
while true do
local event, arg1 = os.pullEvent()
if event == "timer" and arg1 == timerID then
print("My timer was first!")
return
end
if event == "key" then
if arg1 == 45 <—————— got it (push x)
print("Key was first")
return
end
end
end
