effect controls – slider parameters – 7 values, slider jumps directly from 0 to 1

[Walter Soyka]

[Jadwiga Kowalska] “When I edit the slider parameters, I can adjust that the range is from 0-7, but if I use the slider it’s going through 0.01, 0.02, 0.03… etc. It would be nice when the slider would jump directly from 0 to 1 to 2 to 3 etc.”

Alt-click on the slider’s stopwatch icon, and paste the following expression:
Math.floor(value)
This will truncate any decimal values, always leaving the slider with a rounded-down whole number.

I’d recommend using hold keyframes [link] where appropriate, for more control.

the Math.floor(value) works when I add it – but what else do I need to write in the expression, so that it keeps my range from 0-7 and doesn’t jump to >-1 or 8<?

thank you!

[Jadwiga Kowalska] “the Math.floor(value) works when I add it – but what else do I need to write in the expression, so that it keeps my range from 0-7 and doesn’t jump to >-1 or 8<?”

x = Math.floor(value);
if (x > 7) x = 7
else if (x < 0) x = 0;
x;

This will limit the returned value to whole numbers between 0 and 7, inclusive.

The true value of the slider itself can actually be much larger or smaller (it ranges from -1,000,000 to +1,000,000), and it can be fractional — as you’ll see when you scrub it — but it will only ever return a whole value from 0 to 7 when evaluated for other expressions like time-remapping.
