For example, if higher degrees is looking upwards and headZone results in 30 degrees and your incident angle is 32 degrees we would then have a head-shot.
The result is a series of cutoffs in degrees that represent each possible hit zone.
This means that during the onHit event we need to compute what portion of the target's body was struck based on the assailant's viewing angle and position. So we don't know anything other than a target was struck by a certain attacker when this event fires. Maybe we can hope Skyrim SE improves Papyrus and adds this functionality. It would of course be better if Papyrus and the underlying physics engine Havok in this case exposed which part of the skeletal mesh was affected when reporting on a collision the onHit event is merely an event generated for a collision. There's no alternative since the onHit event that is exposed when a target is struck does not include any coordinates of impact nor does it include hit box enumerations. To add locational damage to Skyrim one needs to do math.
