as someone who procrastinates a lot, i'm building a timer in decker using a field and a button to both act as a focus tool and also to apply some newfound programming knowledge. i have the basic countdown, but i'm wondering how i can make the program delay a second before going through the while loop again. any help is appreciated!
on click do while display.text>0 display.text: display.text - 1 #delay goes here end end
You could use the sleep[] function to wait a given number of frames. "sleep[60]" would delay for approximately one second.
A different approach for timing (which could be more accurate over longer time periods) would be to use `sys.now` or `sys.ms` to record a starting time and then consult them periodically to determine how much time has passed, possibly using "sleep[]" to delay between checks. (See: the System interface)
sleep[] looks a bit unsatisfying, as the card is not interactive as it waits, so the label isn’t that readable.
I have tried this:
Make a textfield to store a timer (here I used “timer”) initially set to 0. You can put it on another card if you want to hide it out the way.
Card:
on view do
timer.text:timer.text+1
if (timer.text<0) & ((10%timer.text)=0)
display.text:display.text - 1
end
go[card]
end
Button:
on click do
timer.text:(display.text+1)*-10
end
Edit: I was late to the party. Using sys.now as suggested above sounds like a more suitable approach :)

here's the finished timer! not exactly the greatest thing ever but as a first project i'm quite happy with it
