Hello, does anyone know if there's a command which checks if the target was hit BY someone specified?

Something like that:

If GetHit Player == 1

If the NPC to which this script is bound is hit by player, then...

I know there's GetHit in FOSE/NVSE already, but it doesn't work this way. I also checked Fallout 3 Commands and FOSE Commands, but as everyone knows, FOSE database is pretty outdated.

Also something like that would be welcome as well:

If GetDamagedPercent Player >= 0.25

If the NPC to which this script is bound loses at least 25% of its health because of player, then...
