Character rotation question

Hey.

I am trying to rotate my enemies certain degrees (-60,60) with an event tick, when he reaches -60 he has to rotate to +60.
I tried some thing like clamp angle and more stuff but its not working for me. How can I make this simple rotation? I know this should be very simple but I can’t find out a way to do it.

If anyone can help me I would appreciate it.

Thanks
