Please add a plugin called AssassinPlugin.
It is a plugin that allows 2 player worlds (I don't know if I'm right) to be used as a "hunter/ assassin" vs. speedrunner. The hunter/ assassin has an unlimited life count, but the speed runner only has one life. the hunter/ assassin has to try and kill the speedrunner before they complete the game.
The hunter/ assassin has a compass that points towards the speedrunner, but if the speed runner looks at the hunter/ assassin they will freeze giving the speedrunner the ability to run away.
It is available for all the 1.14 versions, (not snapshots).
It is made for Spigot
"What the plugin does:
Whenever the target is looking directly at the assassin, the assassin cannot move, place or dig blocks, or hit the target. This looking effect is blocked by blocks (except blocks you can walk through). For the assassin to win, all they have to do is punch the target once, while the target tries to win by completing Minecraft.
Commands:
/assassin <assassin> <target>: starts the assassin plugin, you can only have one instance running at once as it will just replace the previous instance at this time (lost when the server is stopped). Permission: 'hamarb123.assassin'
/assassin: stops the assassin plugin. Permission: 'hamarb123.assassin'"
