I have been working on a stopwatch/countdown program, and I am having problems with the code.
Here's the problem:
Code: M→Z
20→A
While Z≠0
A+1→A
A-1→A
A+1→A
A-2→A
A+1→A
A-1→A
If S=0:Then:M-1→M:Z-1→Z:60→S:End
If A=0:Then:Then:S-1→S:20→A:End
End:Disp "TIME UP!"
I do have it output( it in the code, but when it has a minute left, it displays "TIME UP!". I want it to display it when everything equals 0.
What you want is startTimer aka. startTmr
That gives you accurate seconds!
The easy and modular countdown way (Uses A for total secs, Uses D for secs left; Destroys B and C; Put your code instead of the Disp D):
Code: Input "Secs: ",A
startTmr->B
checkTmr(B)->C
While C<A
A-C->D
Disp D
While A-C=D
checkTmr(B)->C
End
End
Disp "TIME OUT!"
The heavily optimized countdown oneliner (supply total secs in A; Destroys Ans and B):
Code: 1:startTmr->B:While Ans:A-checkTmr(B:Disp Ans:End
The easy and modular stopwatch way (Uses B for elapsed secs; Destroys A), press any key to stop the stopwatch:
Code: startTmr->A
Repeat getKey
checkTmr(A)->B
Disp B
End
Disp "BREAK!"
Also, if you want a counting up timer, this is a good way to do it. It is easily modifiable to go down as well.
Code: 0->B
Repeat Ans
Disp B
B+1->B
startTmr->A:0
Repeat Ans+checkTmr(A
getKey
End
End
Countdown:
Code: 10->B ; Number of Seconds
While B
startTmr->A
Repeat checkTmr(A:End
B-1->B
Disp B
End
Thank you for the count-up timer. While I do have that part, I just needed something for a countdown timer. Thanks!
