Vector3.Angle is wrong
I am trying to get the throwing angle of an object thrown in VR. The white line is the velocity of the controller, I am taking an average of the last frames here to describe the direction the controller is moving. While throwing, I want to get the angle between the avg. velocity and the horizontal forward direction (red line). However, my code reports the wrong angles, no matter what I try.
In the example picture, the reported angle is 11 deg. My code is:
Vector3 angleOne = AttachedHand.velocity.normalized;
Vector3 angleTwo = new Vector3(AttachedHand.velocity.x, this.transform.position.y, AttachedHand.velocity.z);
//float angle = Vector3.Angle(angleOne, angleTwo);
float angle = Mathf.Atan2(Vector3.Magnitude(Vector3.Cross(angleOne, angleTwo)), Vector3.Dot(angleOne, angleTwo));
angle = angle * Mathf.Rad2Deg;
Best Answer
Uhm the horizontal vector that points in the same direction of your velocity is
new Vector3(AttachedHand.velocity.x, 0, AttachedHand.velocity.z);
using transform.position.y makes no sense in a direction vector.
