Passing player ID through hitting object.

Anyone got some tips on passing player ID of sorts for scoring a point when hitting a physics object into another player.

Like dodgeball, hit a ball it hits a player. You get a point. Opponent was hit by player by ball.

Same goes for hitting a player and they die as of result from say falling off a cliff.

I was debating putting a variable in the object so when it’s hit, it holds that id and when it hits a player it uses that if as the damage delt from.

The falling off a cliff I’m not sure how to accomplish though, except a similar variable and on death (when hitting a volume trigger it uses that variable)

Thoughts? I’d post some blue prints but hdd crash waiting on one to get my development back up
