Guide and examples

top orders every player who has ever played by one of their own variables, highest first, whether they are online or not:

command /baltop:
    trigger:
        send "&6Richest players"
        set {_place} to 0
        for each {_name} in top 10 players by {coins}:
            add 1 to {_place}
            send "&e#%{_place}% &f%{_name}% &7- %{%{_name}%.coins}% coins"
        set {_mine} to rank of player by {coins}
        send "&7You are #%{_mine}%"

Syntax	Result
`top <n> players by {<name>}`	A list of up to `n` player names, best first
`rank of <who> by {<name>}`	Where that player stands, 1 being the best; unset if they have no value

The variable is each player's own: {coins} here means the same as {%player%.coins}, and both spellings are accepted.
Only players who have a number in that variable are listed.
The first time a list is asked for after a restart, HyperScript reads every player's data to build it, which on a large server with a database can take a moment. After that it is kept up to date as values change and costs almost nothing.
