Working with angles in 2D

Hi

I have the following code which gives me an angle of direction between two vectors. However, the angle is only ever 0 to 180, whether the direction is on the left, or the right of the scripted object. I need it to go from 0 to 360 so that I can clearly indentify whether the direction is to the left, right, back, front etc.

Code (CSharp):

1.     public void SetDirection(Vector2 newDirection)
2.     {
3.  
4.         Vector2 tempLocation = transform.localPosition;
5.         Vector2 tempVector = newDirection - tempLocation;
6.  
7.         float angleRadians = Mathf.Atan2(tempVector.y, tempVector.x);
8.         angleDegrees= angleRadians * Mathf.Rad2Deg;
9.  
10. }

angleDegrees is only ever 0 to 180. Need it to be 0 to 360.

Any ideas?

 

it goes from -180 to 180, check for the negative values.

if you really want it to be 0 through 360 add 180 to your final angle

And you can also use Vector3.SignedAngle:

You don't necessarily have to use Atan2.
