Question

I have an angle A and a target angle B

The range for the angles is -180 to 180

I want angle A to move X degrees towards angle B

The problem I’m facing is if A is say 170 and B is -170, it is clearly faster to increase to 180 and jump to -180, but I always get a negative X when comparing the angles. So instead of taking the fastest way it will take the longest way.

I hope someone will understand my poorly formulated question 🙂

A = A + ((A-B) / Math.Abs(A-B)) * speed * -1;

Edit: Added code

Answer 1

Calculate the difference between the two angles. If the resulting angle x is bigger than 180 degree, then walk in the other direction using this angle: 360-x.

If you use the range from 0 to 360 you can calculate the difference easier.
