How can I get the opposite of a direction?

Like adding 180 degrees to and angle. I don't think there is any more explanation needed for this.

Pi is 180 degrees for any angle calculations:

Code: Select all

opposite = direction + math.pi

Also 90 degrees is half pi and 360 degrees is a 2*pi. But people must to know about the Tau.

How is the direction given? If it's a vector, then just change the signs of the components.

Thanks so much. That worked.

Off topic, but thanks for sharing that link! I'm a bit of a math nerd and I hadn't heard about that.

All hail Tau - the more sensible constant!
