Jak napisać skrypt na sprawdzanie koordów gracza?

command /koordy [<player&gt]:    trigger:        set {_} to location of argument-player        send "Kordy gracza %argument-player% to: %{_}%"

command /kordy [<player&gt]:	trigger:		if arg is set:			if arg is online:				send "Kordy Gracza %player-arg% X:%x-coordinate of player-arg%, Y:%y-coordinate of player-arg%, Z:%z-coordinate of player-arg%"			else:				send "Podany gracz nie jest online"		else:			send "Podaj nick"

Dzięki za pomoc.
