command /무지개발광:

    trigger:

        set {_colors::*} to pink, red, orange, yellow, lime, cyan, indigo, purple and magenta

        set glowing of player to true

        loop 10 times:

            loop {_colors::*}:

                set glow color of player to loop-value-2

                wait 3 ticks

        set glowing of player to false

이렇게 했는데 에러가 나네요 무슨애드온이 필요하나요?
