I was trying to find the angle between 3 vector3 points obtained from the screen swipe. The first vector3 point is the first touch position fp, the second is some intermediate touch ip and the third, the final touch position lp.
I tried the unity’s Vector3.angle to get the angle but I was getting some angle even if I swiped in a straight line. Here is what I tried
AB = ip-fp
BC= lp-ip
Then I applied Vector3.angle(AB, BC) but the result is not what I’m looking for. Any solutions?
