Switched from Vector2 to Vector3, as we are in 3D. Improved the hitpoint calculation, as with a SphereCast, we must pay attention to: **SphereCast will not detect colliders for which the sphere overlaps the collider. Passing a zero radius results in undefined output and doesn't always behave the same as Physics.Raycast.** We calculate the closest point on the ray (direction of the spherecast) to the center of the collider. Then we ask Unity to give us the closest point from it on the collider. We consider this new point as our Hit point and use it for further calculation.
