Location based damage?

[Abraxas77]

I am trying to create a mod that allows rogue / stealth type players to execute sneak attacks even during combat by getting behind their enemy. It would be a nice complement to the great deft movement perk mod that slows time during power attacks automatically.

 

I noticed another mod that already has location based functions (Unarmed Combat mod) in which the creator was able to create power attack abilities that disarmed opponents if they were hit from behind. Anyone know how the game identifies that the player is able to execute a sneak attack or how the game identifies the if the player is attacking an enemy from behind?

 

Thanks for any thoughts.
