NetLogo: Changing a heading to the opposite value

Question

I need to calculate how to reverse a heading within a NetLogo script e.g. a turtle has a heading of 0, I need to flip this to 180 so they travel in the opposite direction.

I've tried [360 - heading] with limited success.

Answer 1

For the record heading - 180 works, of course, but if you want to be more "turtle centric", you could ask your turtle to rt 180.

Answer 2

Ahh got it. I knew I was close

[heading - 180]
