czm nie dziala mi zaden z tych prefixow

Nie ma takiego czegoś, Ewentualnie można zrobić tak:

on chat:
	cancel event
	send "%{GrupaSkript::%player%}% &a%player% &7&l>> &7%message%" to all players
command /grupa [<text>] [<text>]:
  	trigger:
  		if arg 1 is set:
  			if arg 2 is set:
  				set {GrupaSkript::%arg 1%} to "%arg 2%"
  				send "&cNowa ranga przed nickiem gracza &a%arg 1% &cto &a%{GrupaSkript::%arg 1%}%" to player
  			else:
  				send "&cPodaj range!" to player
  		else:
  			send "&cPodaj nick!" to player

lub tak:

on chat:
	cancel event
	if player has permission "admin":
		send "&cAdmin &a%player% &7&l>> &4&l%message%" to all players
# I tak dalej...

Musiałbyś zrobić prefixy w sk a  rangi w pexie

np:

on chat:
	if player has permission "Gracz":
		set {_ranga} to "&f"
	else:
		broadcoast "%{_ranga}% &9%colored player's name% &7&l» %message%"

i w pexie stwórz range Gracz

pozniej. /pex group Gracz add Gracz

nadaj komus i mozna pisać

i z tagami

on join:
	set player's tag to "%{_ranga}%"
