public static float Angle(Vector2 from, Vector2 to);


from The vector from which the angular difference is measured.
to The vector to which the angular difference is measured.


float The unsigned angle in degrees between the two vectors.


Gets the unsigned angle in degrees between from and to.

The angle returned is the unsigned angle between the two vectors.
Note: The angle returned will always be between 0 and 180 degrees, because the method returns the smallest angle between the vectors. That is, it will never return a reflex angle. Angles are calculated from world origin point (0,0,0) as the vertex.
See Also: SignedAngle function.

//Draw lines from origin point to Vectors Debug.DrawLine(, m_MyFirstVector, Color.magenta); Debug.DrawLine(, m_MySecondVector,;

//Log values of Vectors and angle in Console Debug.Log("MyFirstVector: " + m_MyFirstVector); Debug.Log("MySecondVector: " + m_MySecondVector); Debug.Log("Angle Between Objects: " + m_Angle); }
