I've been dabbling in redstone since my programming computer has been down for a week, and I came up with this problem: I need to give the killer of a specific player an emerald in vanilla minecraft. Here's the solution that I came up with: Put each player on a separate "team", each with its own team color. Give each of them their own respawn point. Give each player an objective with the compound criteria teamkill for each color. When a player dies, you can identify the player who killed them by their score of 1 for the killed player's color. Give them an emerald and reset that score to 0. Here's the problem with it: The player's nametags are colored various meaningless colors, which is annoying (especially considering there are only 2 teams). Also, it uses up the teams, which means that anything that tries to use teams for a more important reason (i.e. actually identifying teams without plugins) will glitch it up. Does anyone have a better idea?
