Currently in CV2 there is no way to detect who killed who. When I think of what you CAN'T do with CV2, this is the first thing that comes to mind. If we had an event receiver that executed when a player was hit and had an output for the attacker and defender (and hopefully their health), that would be extremely helpful and would open up the possibilities for much more complex games (I've got an idea right now that I can't build until this is a thing). Thanks for considering!
