I have a timer with 1sec interval. The same code has different result in time counting. In Oregon300 is 10-times faster than Emulator!

T = Wherigo.ZTimer(cart)
T.Name="timer1"
T.Duration=1        -- sec
T.Type="Interval"   -- "Interval", "Countdown"
T.startTime = nil

function T:OnTick()
  if (T.startTime == nil) then
    T.startTime = os.clock()
    LOG("start_time = ", T.startTime)
  end

  LOG("now= ", os.clock()) 
  LOG("now-start_time = ", os.difftime(os.clock(), T.startTime))
end

Emulator relusts:

that would be because os.clock() approximates CPU time spent, which will obviously be much different between a powerful desktop PC and a hand-held GPSr

what you should be using is os.time()

I tryed this code

os.date('*t').sec

Results were the same for both devices.

Iam making an animation. Because time intervals are different, I must measure total animation time. It is necessary fo next part of game.


I have second problem with timers - Using timer:Stop() inside timer:OnTick() is nonfunctional. This code inside timer:OnTick() is OK: timer.OnTick=nil and timer=nil.

this is better: timer.Type = "Countdown"
flips the timer to Countdown mode and Wherigo will not reschedule the next interval. plus you don't lose the option of restarting the timer later

This is simple and effective solution. Díky
