Timer with individual event.time

Getting Started Newbie Questions
#1

Good day I need help on my timer

right now when I execute “event.time” with 2 of my timers, It displays the same.

sample:

local function timerA(event) print("TIMER A : ".. event.time) end timer.performWithDelay(1000, timerA, 0 ) local function timerB(event) print("TIMER B : ".. event.time) end local function startTimerB(event) timer.performWithDelay(1000, timerB, 0 ) end timer.performWithDelay(5000, startTimerB, 1 )

Both will have the same value. Even though Timer B has started late. How can I make both timers have it’s own “event.time”

#2

I think that event.time returns the same as system.getTimer(), which is the number of milliseconds since the app was launched. 

The easiest way I can think of to work around this is by having your own variables for tracking the time between timer calls:

local totalTimeA = 0 local totalTimeB = 0 local lastTimeA = nil local lastTimeB = nil local function timerA(event) totalTimeA = totalTimeA + (event.time - lastTimeA) lastTimeA = event.time print("TIMER A : ".. totalTimeA) end lastTimeA = system.getTimer() timer.performWithDelay(1000, timerA, 0 ) local function timerB(event) totalTimeB = totalTimeB + (event.time - lastTimeB) lastTimeB = event.time print("TIMER B : ".. totalTimeB) end local function startTimerB(event) lastTimeB = system.getTimer() timer.performWithDelay(1000, timerB, 0 ) end timer.performWithDelay(5000, startTimerB, 1 )

totalTimeA/B will be the length of time that timer has been running. 

lastTimeA/B are used to record the current time so that it can be used in the next timer call to work out the time difference between calls.

I ran your code, I’m getting different values for timer a and timer b:

@Rob Miracle, yep they are different but, my desired output is like this, timer B should have a starting value of zero, and timer A should continue

@Alan QuizTix, your code works, but it appears that It is not good for a shared function.
