Hi guys,

I've been playing with LiveCode for a week or two now, done the tutorials on the LiveCode website (culminating with the 3-5-7 game) and have since tried my hand at realizing a project that I've wanted to create for myself: A countdown timer, specifically to use at the gym. My end goal is to implement the following functions:

User can set any time desired (in seconds, I'm not really worried about minutes/hours)
Can stop/start the timer at will (basic stopwatch functionality)
Can be set to repeat the set time automatically (i.e. a round timer)
Can set two (or more) intervals, e.g. 60 second interval followed by 20 second interval, and repeat. (Like 60 seconds of work, 20 seconds rest)
Play a tone when an interval is completed
And... Run on Android. Some day

That's the big picture. Right now, I'm just working on the countdown. I got it to work, in that I put a number into a field, click a button, and the number counts down by 1 every second until it reaches zero. Here's the code I used (on the button script):

Code: Select all

global timeLeft, interval
on mouseUp
   put field "timer" into interval
   put field "timer" into timeLeft
   startTimer
end mouseUp
command startTimer
   repeat for interval times
         wait 1 second
         get timeLeft - 1
         put it into timeLeft
         put timeLeft into field "timer"
      end repeat
end startTimer

My problem is, I can't do anything else while the timer is running... Any input (clicks, typing, etc.) isn't registered/executed until the timer is finished. This makes it problematic to program a stop/reset button, as button clicks don't register until after the timer has reached 0. How do I allow the user to continue to do stuff even while the timer is running?

Please keep the explanations kindergarten-level; I'm a total newb to LiveCode and don't have any previous coding experience. This is my first non-tutorial attempt at creating an app

If you want messages to be sent during the wait add "with messages" to the end of the wait statement.

Wow, jackpot! Yes, that was exactly what I needed, and now nothing can stop me!*

*Until I have another question

Thanks for the rapid and on-point response, I'll keep updating this thread as I get further in.

That's the spirit! With that sort of feeling guiding your work, it will be truly the case.
