5 Minute Countdown

[Dan Ebberts]

You would need a more complex expression. Here’s one that uses a checkbox control on the text layer to drive the count down. The count only proceeds when the checkbox is in the “on” state.


p = effect("Checkbox Control")("Checkbox");
accum = 0;
ct = inPoint;
cv = p.valueAtTime(inPoint);
for (i = 1; i <= p.numKeys; i++){
kt = p.key(i).time;
if (kt <= inPoint) continue;
if (kt >= time) break;
accum += cv*(kt - ct);
cv = p.key(i).value;
ct = kt;
}
accum += cv*(time-ct);

rate = -1;
clockStart = 1440;
function padZero(n){
return ((n < 10) ? "0" : "") + n;
}
clockTime = Math.max(clockStart + rate*accum,0);
t = Math.floor(clockTime);
min = Math.floor((t%3600)/60);
sec = Math.floor(t%60); min + ":" + padZero(sec) + ":" + Math.floor((clockTime%1)*10)

Wow…
Just wonderfull!!
Thank you!!

Hi code works great but I am wondering if their is away to get rid of the leading number when they turn to zero.

I’m not sure which version you’re talking about, but to eliminate leading zeros you would eliminate the call to padZero():

rate = -1;
clockStart = 7200;

function padZero(n){
if (n < 10) return “0” + n else return “” + n
}

clockTime = Math.max(clockStart + rate*(time – inPoint),0);

t = Math.ceil(clockTime);
hr = Math.floor(t/3600);
min = Math.floor((t%3600)/60);
sec = Math.floor(t%60);
“” + hr + “:” + min + “:” + padZero(sec)

Hi Dan I am confused. Here is the code I am using. I want I five minute countdown. But when it gets down to just seconds I dont want the zeros to shows.

rate = -1;
clockStart = 300;

function padZero(n){
if (n < 10) return “0” + n else return “” + n
}

clockTime = Math.max(clockStart + rate*(time – inPoint),0);

t = Math.floor(clockTime);
min = Math.floor((t%3600)/60);
sec = Math.floor(t%60);
min + “:” + padZero(sec)

I’m still not sure exactly what you’re after, but try changing the last line to this:

(min > 0 ? min : “”) + “:” + padZero(sec)

and if that’s not it, try this:

min > 0 ? min + “:” + padZero(sec) : sec

That a little closer. What I want it to do is somthing like this count down from 5:00, 5:59,5:58…..4:00…3:00…1:00, 59, 58 …10, 9, 8, 7 … 1, 0

Sorry for all the confusion

Now I’m confused. Isn’t that what the second variation from my previous post does?

Dan

[Chad Keddington]

The last post does do that except when it gets down to sec the semi colon is still showing. The previous one were I get ride of the call to padZero does count down in sec but does not show the minutes.

Thanks for all the help.

Hi Dan,

That script was very helpful…. Is there any way in the script that I can start the countdown after couple of seconds….

rate = -1;
clockStart = 300;

function padZero(n){
if (n &lt; 10) return "0" + n else return "" + n
}

clockTime = Math.max(clockStart + rate*(time - inPoint),0);

t = Math.floor(clockTime);
min = Math.floor((t%3600)/60);
sec = Math.floor(t%60);
min + ":" + padZero(sec)
