Need help creating a stopwatch!

[eric1894]

I need some help on how to create a stopwatch that shows hundredths. The Date & Time object only shows hours, minutes and seconds. Not hundredths. Can someone please help me?

Keep track of which frame number it is.

Hundreds: (Frame Number*1.0/Frame Rate) mod 1*100
Seconds: (Frame Number/Frame Rate) mod 60
Minutes: (Seconds/60) mod 60
Hours: Minutes/60

If you want an anglog'ish stopwatch, you can use the values you get to set the angle of some active objects to act as hands.

the game only elapses at the maximum framerate you have set it to.

If you have 50 frames per second, the smallest increment of time you could adjust is by 0.02 seconds. However, you can read the internal timer in terms of thousandths since then start of the frame by using "timer" in the expression editor.

This is inside the expression editor, under the "Timer" object. The very first property it has


To get hundredths from this, just divide by 10. Keep in mind this value is cumulative from the start of the frame and won't just be the "thousandth" place digit, unlike "time in seconds" and so on. If you want to retrieve just the last few digits, use the "Mod" function.

For example, the line:

"timer mod 1000" would give you the thousandths places

or

"(timer / 10) mod 100" would give you the hundredths places

I recommend my method if you're doing e.g. a speedrun or race timer. First, there's no possible reason for accuracy greater than the game's FPS if you're timing something that happens in the game itself. You don't need accuracy greater than 0.02 seconds if nothing happens in between. Second, if by some reason there's a latency caused by e.g. a CPU spike due to something in the game or some scheduled application start or auto-update, you want the stopwatch to slow down to the speed the game is currently running in. If you're using a timer that's not frame based, you can actually get a worse score because there were a latency.

Just note that I didn't mean you should get the framerate via the FrameRate expression, that'll produce dodgy results if the framerate changes during gameplay due to CPU usage. You should just use a constant that's equal to the game's default framerate.
