Playdate.timer value increases between calling :pause() and :start()

SDK Bug Reports
#1

It looks like a timer’s value keeps updating even after it’s been paused? I expected it to not change after :pause() was called, and to only begin incrementing again after calling :start()

I put together a minimal repro - if you press A and check the console output you will see the value incrementing normally, but if you press A again, wait for a couple of seconds, and press A once more, you will notice the value has jumped as though the timer was never paused.

import 'CoreLibs/timer'

local timer = playdate.timer.new(12000, 1, 1000)
timer:pause()
timer.updateCallback = function ()
  print('timer update', timer.value)
end
timer.timerEndedCallback = function ()
  print('timer end', timer.value)
end

local isPlaying = false

function playdate:AButtonDown()
  if isPlaying then
    timer:pause()
    print('paused timer')
    isPlaying = false
  else
    timer:start()
    print('started timer')
    isPlaying = true
  end
end

function playdate.update()
  playdate.timer.updateTimers()
end

For now, editing CoreLibs/timer.lua so that the :start() function sets the timer’s _lastTime value back to nil seems to work:

function playdate.timer:start()
	self._lastTime = nil
	self.paused = false
end

Is timer:pause() broken, or am I just not using it correctly?

Thanks for the workaround!

I’ve also reported this, a long time ago, in the days when the was an issue tracker.

Is this likely to get fixed soon?

I've tagged Dave. Until then you can edit the lua files to add the fix yourself
