Hey, Everyone! I was just wondering how would you make it so a sign says, Hey, <player> You have 0 kills! So how can I like put something on a sign that only that player can see?
To make it so multiple players only see their name, you'd probably have to send their client packets.
@EpicCraft21 Probably second. @MordorKing78 I could just suggest same as CodePlaysMinecraft. Send packets to players. Try it when player joins, and when player kills someone else. BTW, for kills be a whole line. Maybe 3-4 characters won't be enough.
