This plugin adds commands and functionality for making your players hunt for a chest when you want them to! There are many like it, but this one is unique because it marks the vague location of the chest on the players's maps!
ChestHunt.admin: Allows you to start a chesthunt or stop it.
ChestHunt.player: Allows you to join, leave, or win a chesthunt.
/ChestHunt: shows help.
/ChestHunt join: Joins the chesthunt if active
/ChestHunt leave: Leaves the chesthunt if you are in it.
/ChestHunt start: Starts a chesthunt if you are standing on top of a chest.
/ChestHunt stop: Stops the chesthunt forcibly. This is the only command that can be used as console.
Just drag and drop, then reload/restart and it should work!
Stand on top of a chest and type /ChestHunt start. Then anybody with the permission who does /ChestHunt join, will see a red square marking an area where the chest is, if that map shows where the chest is. It looks something like this:
