I have to make a count up and count down clock with 1/100 seconds display.
I often use a script that i found on this forum to set the correct format 00:00:00 / hour:minute:seconds but how do i get the last 2 or 3 digits depending on the precision.

In the example i use the sconds display to count 1/100, but thats wrong.
Now i hope someone knows more about it.

Kind regards,

Opus has several ways to get the milliseconds. You simply keep things in decimal terms rather than making them hours:minutes... 60 based. So you just use that plus math.round or math.ceil etc. on the milliseconds part. You can also specify a formatting mask "5.2" to show something like 03.45 sec.

There are several sample .IMP files posted already on the forum with countdown timers, quiz clocks, etc. that have done this work.

This is copied from an old post. It may help.........


""""I had noticed that the Clock Action has the option to display time down to hundredths of a second and I wondered if the Script Clock has the same capability....which it does


myClock = CreateClock("ScriptClock","clock_var","[hh],[mm],[ss],[ff]")
myClock.Start()


This will give you a script clock with hundredth of a second resolution BUT.....there is no 'myClock.GetTenths()' operation, however the tenths and hundredths can be extracted from the clock_var variable by using the following constant expressions in insert variable.




(clock_var.toString()).charAt(9)-------for tenths of a second
(clock_var.toString()).charAt(10)------for hundredths of a second.""""

I use this in many applications and it looks good and it runs very smoothly.

Stupid me, i did not look at the standard clock function that also has the tenth and hundreds function [ff]
But now the count down with tenth and hundreds, how do you do that in a script?

Here is an extract of code I used to create a countdown timer, but only to tenths resolution. You will have to play around with the code and char positions to get it working for your application.



Where 'TimePeriod' is the countdown time in seconds.
I convert the clock to seconds to do calculations, then convery back (Remaining1) to hexagesimal to display.

Remember, Opus is even driven, You need to create an event (trigger)
to initiate the code above. I use a half second ticker, so it performs the calculations every half second, for display purposes...it is OK.
It is not possible to get real 'calibrated' accuracy to hundredths of a second from a clock like this. If you use a button press to stop the timer, you can not be sure of the time it will take between the trigger being recieved and the program doing anything about it. It depends on what the PC is doing in the background. Tickers are not 100% accurate.

Thanks for your reaction and script. I'm gonne try it right away.

Sorry I didn't have time to put an imp together for you, but it's better to learn for yourself
There are chunks of script available to convert from seconds to Min/sec with the correct format.
what is your timer for?

Sandy

Hi Sandy,

My timer is for several applications. One is for an icehockey scorboard. Therfor i don't need the milisecond option. The other application is for a new TV show i produce. To give it more pro look on TV i need the miliseconds.

I tried to get the script work. So far... i need more practice.
If you have a simple IMP example of the countdown let me know.

kind regards,

It would be easier to correct what you have. (I think) can you post your IMP? My clock is embedded in a dual deck MP3 player and difficult to extract the script.

Sandy

I don't have an page yet. It must be a countdown with miliseconds. The player in the TV show will get money if he gives the right answer. The reason we need the tenth and hundreds of seconds is that he can win or loose it he can stop the counter on an exact number.
What i need to display is a counter full screen on an HD lcd tv 1920x1080.
One button to start, and one button to stop the count down time.

Kind regards,

here is a very basic countdown timer. It is not fully error trapped, but it shows one way of doing it. hopefully it will be some help to you. I was going to make it an up/down counter, but didn't have time

Thanks, looks like it's just what i need.
If the page for the pilot TV episode is ready i will post it.
