If I have an object that I am rotating from 5 degrees to 355 I would want to rotate it counter-clockwise. If I want to go from 5 degrees to 10 degrees I would want to rotate it clock wise. How would I write a program that tests which direction to go based on angular distance so that I don't rotate in the wrong direction? I feel like this is simple and I've seen it a million times but can't seem to figure it out or find it in the forums.

One idea may be to have a variable related to that object that you can test. So, whenever you go to move the object you also update the variable to keep track of it.

Here's code that works in some instances but it's not smart enough to go the shortest distance. I know that I can some how use wrapvalue but can't figure it out.

isn't there a Object Angle x/y/z command? Just use it to get your object's current angle, then do the rotation accordingly.

just a thought

Yeah I was using variables to demonstrate the problem.

To clarify, my problem is that the object starts at 5 degrees goes 5,6,7 etc. until it gets to 350 because 5 is lower than 350. I would like logically to have it decide that its shorter to go 5,4,3,2,1,359 etc. until it gets to 350 being that that is the shorter distance.

Hmm I think using ATANFULL has solved my problem..
