Hey, so for my SoupPvP server I made the "currency" called KillPoints, when you kill a player you get one and when you die you lose one.

Basically I'm trying to make a command to reset the server's killpoints for when I do stat resets, and I cant figure out how to get all players who have ever joined in a variable. This is what I have so far:

Code (Text):

1. command /resetserverkillpoints [<text>]:
2.     aliases: rskp
3.     trigger:
4.         if executor does not have permission "yochranstaffcore.management":
5.             message "&fUnknown command. Type '/help' for help."
6.         else:
7.             message "&aAre you sure you want to do this?"
8.             message "&aType &2Yes &aor &cNo &ain chat to confirm."
9.             set {rskp.%uuid of player%} to true
10.  
11. on chat:
12.     if {rskp.%uuid of player%} is true:
13.         if "%message%" contains "No":
14.             cancel event
15.             message "&aYou cancelled resetting the server's killpoints."
16.             delete {rskp.%uuid of player%}
17.         else:
18.             if "%message%" contains "Yes":
19.                 cancel event
20.                 message "&aYou have reset the server's killpoints."
21.                 loop all players:
22.                     set {total-killpoints::*} to 0
23.                     delete {rskp.%uuid of loop-player-1%}
24.  

Basically for the on chat: thing, I'm trying to make it so that when you type "yes" it sets the killpoints of all players who ever joined to 0. Whenever I run the command and type "yes," it doesnt reset anyone's killpoints. Ive tried many things like {total-killpoints.%uuid of all offline players%}, none of it seems to work. Please help.
