Counter clockwise using expressions
on May 24, 2019 at 9:36:42 am

I am trying to use a couple of elements rotating in several directions (clockwise and counter clockwise), using expressions. Previously keyframes were used, but I want to use expressions, as the length of the animation is about 10 mins and setting keyframes is almost impossible.

Any help would be great.

time*120 // 120 can be different depending on the speed I wish to use.

Hey Stephan, maybe it sounds too simple, but adding minus in front '-time' will go other way around. Unless, its not what you are looking for!

Thanks Thomas, will try when I can.

I do have one more question. Is it possible to set a start position, as at the moment the rotation always starts at 0.

Stephan - if manually, then its just an addition of a number like 'time + 45', etc.

If more dynamically, you could also multiply it by an index, or random number generator - there are many ways on doing this, depending on your needs !
