Adding special armor detections prior to damage

[cadergator10]

I'm trying to add some armor that works with the Modern Warfare mod where specific bullet types can be blocked by the armor sometimes completely, sometimes a percent chance depending on how damaged it is, sometimes not at all (like real bulletproof armor might).

I'm trying to interface with first aid by overriding the LivingDamageEvent with one higher priority, but can't figure out how the mod detects where someone is damaged both with melee or projectiles
