Verification in minecraft?

I wanted that when a player enters the / verify command through pex into the player group and with / verify-romove back to the guest group

I have already created these commands in a script with a message ("sealed") and wanted to know how it is possible that the pex finds out who executed the command and then connects this person to the player / guest group! (Please remember that it is a sk file (script file))!

Schonmal Thanks in advance!

.getPlayer.getName

Why use scripts? : /

What would you take that

Plugins ^^

Which one? Need one where I can adjust the news myself

Make one or write me I can make you one thing: TheSaltyOne # 8410

What's wrong with scripts?
