How do I change who's HUD is displaying data?

Following the networking tutorials, I’ve made a bomb game. However, I’ve added a HUD and an interface for it. All it does is display a message when the player’s health reaches zero or lower. This works perfectly, with one major issue. It displays the death message to player index zero only. So even if he/she didn’t die, it acts as though they did. Is there anyway to get the player index of the character who died?

You using network for your game right ? coz player index is indicate player controller index in the same client, like u play game with your friend in same console you are index 0, and ur friend will be 1. So in client you are always player controller 0.
What you want is sending death message over network to other client as well is it ?

Basically, yeah

So here some fast blueprint i made to handle if your character health reach 0, it will send out event will multicast setting, to all player inform that he has die.
From here you can send die information to your player controller, or HUD to handle this.
This will run on your character blueprint btw.

Thanks a ton, I really appreciate it.
