Making a timer tick

Is there a way to make a timer tick without using os.startTimer() that freezes the rest of the program?

For an example id like a timer to tick once a sec for a count down.

So you want to freeze the program during the timeout time? Just use "os.sleep".

im sorry, i ment doesnt freeze xD

So, it counts down, but doesn't freeze? I don't know if that's possible. I sure can't do it.

Wait, so you mean you don't want execution to stop, that is, you want to start the timer but keep doing other things while it's running? That's what "os.startTimer" is for. You can handle the timer as well as other input with "os.pullEvents".

If you want to use os.pullEvent() but don't want it to stop your program, you can queue a fake event:

local timer = os.startTimer(10)
while true do
  os.queueEvent("fake")
  local evt, arg = os.pullEvent()
  if evt == "timer" and arg == timer then
    do_something()
  end
  -- continue program
end
