Mod Numbers - quickest route to a number

[Ramses]

Lets say I had a variable (A) that I want to always set as a mod of 10 ie 13 would equal 3. Now lets say I had a another variable (B) and if variable B was less than variable A, variable A would be subracted by 1 and if variable B was greater then 1 would be added to variable A. Hmmm... this is difficult to explain.

Basically, what I want to do is sort of like the "rotate towards angle" function that's found in a few of the extensions. For example, if variable A is 9 and variable B is 2, 1 would be added to A instead of subtracted since it's quicker to get to B by adding. How would one do this via expressions? How would you find out if you should add or subtract?

I have tried to find a solution, but didn't come up with anything so far. One hint: Use min(a,b) and max(a,b) to limit numbers. min returns the lower, and max the higher of two numbers. You can use that to limit the difference to -1,1 or something like that.

You probably want to use the Immediate If object..

True that. I tried to do it without it, but forgot suggesting it to Ramses. :blush:

Add this to the <current> value to "rotate" it towards the <target> value:

max(min(((<target> - <current>) + <limit> + <limit>/2) mod <limit> - <limit>/2, 1), -1)

Change -1 and 1 to change the speed.

Awesome. Thanks!
