Resume Timer - New Question

[L.Coder]

Hello, I already program a timer that counts down and I can make that the timer pauses with a button but I don´t know how can I do a button that resumes the timer.

Hope that you can help me

Hi L.Coder

Creating a 'resume' functionality depends on how you coded the 'pause' - so can you share your code?

Kind regards

Dave

EDIT: and also depends on your timer code so can you share that too?

[L.Coder]

Of Curse, first is the code of the timer and then is the pause.

thanks a lot Dave, I hope that you can help me.

Code: Select all

on mouseUp

   put fld “timerDisplay"into CountTimer

   put CountTimer into fld "timerDisplay"

   send "UpdateTimer" to me in 1 second

    

end mouseUp





on UpdateWork

   

   subtract 1 from CountTimer

   put CountTimer into fld "timerDisplay"

   

   if CountTimer>0 then

      send "UpdateWork" to me in 1 second

   else

      wait 0.3  seconds

      send "UpdateRest" to me in 1 second

   end if

   


end UpdateWork

Code: Select all

on mouseUp

   if the visible of me is true then

  repeat for each line i in the pendingMessages

    cancel (item 1 of i)

  end repeat

end if

end mouseUp

Hi l.coder

One of the nice things about a great coding tool like LiveCode is that there are so many different ways to 'skin a cat' - and how you write a solution to a task in the morning might be different to how you write it in the evening ... here is a solid and clunky (but easy to grasp!) way to handle pause and resume:

Code: Select all

local sCounter,sPaused

on startCounter
   put empty into sPaused
   put 10 into sCounter
   put sCounter && "seconds remaining" into fld "fldTimerDisplay"
   send runCounter to me in 1 second
end startCounter

on runCounter
   if sPaused is empty then
      if sCounter > 1 then
         subtract 1 from sCounter
         put sCounter && "seconds remaining" into fld "fldTimerDisplay"
         send runCounter to me in 1 second
      else
         put "Time's up!" into fld "fldTimerDisplay"
      end if
   end if
end runCounter

on pauseCounter
   put true into sPaused
end pauseCounter

on resumeCounter
   put empty into sPaused
   send runCounter to me in 1 second
end resumeCounter

All the code should go in your card and relevant buttons only have to call the startCounter, runCounter, pauseCounter and resumeCounter handlers. Again this is just how I wrote it to show the technique of using 'send in time' together with control of script local variables (sCounter and sPaused)

[L.Coder]

Thanks a lot Dave! I did it, but when I press the button puts "seconds remaining" in the fld. And I don´t know why I´m too lost.

[dave.kilroy]

Hi l.coder - can you describe what you did, what buttons and fields you have, what handlers they are calling, what code you have inside those handlers - and lastly can you describe how you think the system SHOULD be working and exactly WHERE it is breaking down

The reason I'm asking you for these things is that it may well be that writing all these descriptions will lead to enlightenment!

Good luck!

Dave

[L.Coder]

Yes, sure.

Here is the code of the play

Code: Select all

local  CountTimer
local CountRest
local Repeat_Times
local UpdateRest
local UpdateWork
local Opciones

on mouseUp
   
 
   put 30 into CountTimer
   put 20 into CountRest
   put CountTimer into fld "tTimer"
   put CountRest into fld "tClock"
   
   

   send "UpdateCount1" to me in 1 second

end mouseUp






on UpdateCount2
   
   subtract 1 from CountRest
   put CountRest into fld "tRest"
   
   if CountRest>0 then
      send "UpdateRest" to me in 1 second
   else
      exit UpdateRest
   end if

   
end UpdateCount2





on UpdateCount1
   
 
   subtract 1 from CountTimer
   put CountTimer into fld "tWork"
   
   if CountTimer>0 then
      send "UpdateCount1" to me in 1 second
   else
     wait 0.3  seconds
      send "UpdateCount2" to me in 1 second
   end if
      
   
end UpdateCount1

Here is my pause code:

Code: Select all

local VariableStart
on mouseUp
   put true into VariableStart
   if the visible of me is true then
  repeat for each line i in the pendingMessages
    cancel (item 1 of i)
  end repeat
end if
end mouseUp

I deleted my resume code, because i tried to fix it but I only made it worse.

There are 2 timers, you can see that when the first one ends the other starts.
What I want to do is that if I press pause, the procedure stops but if I press resume continue as normal.

[dave.kilroy]

hi l.coder - did you try out the code I uploaded for you? Did the pause and resume work for you? can you see why it worked and why deleting the pendingmessages (at least the way you are doing it) won't allow a resume?

Kind regards

Dave

[L.Coder]

Hi Dave, Yes I did it in a new stack.

I copied & pasted it to prove, and happened what I told you:when I press the button appears "seconds remaining".

Do you know another way to do this? I tried basicly all that I know but maybe It´s not enough.

P.S Thanks a lot for help me.

Regards.

[dave.kilroy]

Hi l.coder - try the attached stack (which has the same code as I posted earlier...)

Kind regards

Hi Dave, Thanks a Lot! really. You helped me a lot, I solved the problem so well, (actually you did it).

Best Regards and thanks again.

[dave.kilroy]

Great news!

For the benefit of others on the forum can you tell us what the 'aha' moment was and/or what advice you would give for the future?

Kind regards

Dave

[L.Coder]

The variable helps me a lot & one advice will be: READ AND STUDY THE CODE As much as you can.

Thank you again Dave.
