Webangle = arccos (dot (A,B) / ( A * B )). With this formula, you can find the smallest angle between the two vectors, which will be between 0 and 180 degrees. If you need it between 0 and 360 degrees this question may help you. By the way, the angle between two parallel vectors pointing in the same direction should be 0 degrees, not 180. Share WebThe tangent of the angle between two points is defined as delta y / delta x That is (y2 - y1)/ (x2-x1). This means that math.atan2 (dy, dx) give the angle between the two points assuming that you know the base axis that defines the co-ordinates. Your gun is assumed to be the (0, 0) point of the axes in order to calculate the angle in radians.
