            message "x: %x-location of clicked block%, y: %y-location of clicked block%, z: %z-location of clicked block%"

on rightclick with stick:

    if player is op:

        if clicked block is set:

            set {2bll::%uuid of player%} to location of clicked block

            message "두 번째 지점이 설정되었습니다."

            message "x: %x-location of clicked block%, y: %y-location of clicked block%, z: %z-location of clicked block%"

이렇게 해서 좌표를 받아왔을때 {1bll::%uuid of player%}과 {2bll::%uuid of player%} 변수를 월드에딧처럼 사각형 지역을 받아오고싶은데 어떻게 해야할까요..
