Hello. I'm trying to make a plugin were you can join a party, and when you join a scoreboard will show all the members of your party and their health on the sidebar. I want the scoreboard to come up when someone does /pa create and only he would be on the scoreboard, but then when he invites someone to the party, they both have the same scoreboard showing both of their health. I don't want anyone having a scoreboard unless they are in a party. I am very new to scoreboards, so I'm having a lot of trouble with it. I've tried doing this, http://pastebin.com/4c2PQeXZ and it showed the health and it worked. Then for some reason when ANY player joined the game, they would show up on the board. I don't know what I'm doing and need some help. Can someone teach me how to do this? Maybe get some tips? Thanks for reading.
