How to get kill count in FPS Multiplayer?

I am just making the blueprint version of shooter example. But I am unable to get kill count and who killed whom.
and also want to know index of the local player and client player controller.

Well you need to create health system which also kills player on 0, projectile that cause damage whould be owned by player they shoot them, as well as traceing you should send refrence of shooter to damage system of targeting pawn. If pawn will know how shot him, it will know who killed him. As for counting, best place to keep those stats arr PlayerState, each player has one same as controller

Thanks for the replay!
