How to pause and resume a timer?

  Timer:start and Timer:stop are the correct way to handle this:
  
  Can you try this code:

  myTimer = Timer.new(100, 0) myTimer:addEventListener(Event.TIMER, function () print(myTimer:getCurrentCount()) end) myTimer:start()   stage:addEventListener(Event.MOUSE_DOWN, function () myTimer:stop() end) stage:addEventListener(Event.MOUSE_UP, function () myTimer:start() end)

  The console should output the count, press the mouse down in the player to call the stop() function and release it to call start() which will resume where it was stopped.

  My code looks like this:
  After the timer counts 10 timers with an interval of 1 second, the code stops counting and do some processing jobs
  
  The problem happens when the next timer:start() starts the timer, but the timer runs twice faster each 1 second
  
  The third round makes the timer 3 times faster.
  
  Any one can explain this? or it is a bug of the timer implementation?

  local timer = Timer.new(1000, 0)   local count = 1   function onTimer(event) print("counter", count) if count == 10 then timer:stop() print("do something!") count = 0 timer:start() end count = count + 1 end   timer:addEventListener(Event.TIMER, onTimer)   timer:start()

  In your example there's no need to stop or start the timer. If you remove timer:stop and timer:start it will run as you expect.
  
  If at this point you wanted to do something that will take some time then I'd suggest stopping the timer as you have, calling the function and then broadcast an event to start the timer again once the work has been completed.

  Right, start the timer outside the callback could work. What I dont understand is why it does not work inside the callback.
  
  stop and restart a timer itself inside the callback sounds logical for me : )
  
  Anyway, thanks!
