사이트에 들어가서 보았는데 무슨말인지 몰르겠어요ㅠㅠ죄송해요.

예시로 구문 한번만 써주신면 안될까요?

#Example 1

set player's default nametag to "bob" #All players now see the nametag as bob

set player's nametag to "potter" for {_p1} #{_p1} now sees the nametag as potter

set player's default nametag to "weird" #All players except for {_p1} now see the nametag as weird

set player's nametag to "nonweird" #All players (including {_p1}) now see the nametag as nonweird

#Example 2

set player's default nametag to "diamond" #All players now see the nametag as diamond

set player's nametag to "emerald" for {_p1} #{_p1} now sees the nametag as emerald

reset player's default nametag #All players except for {_p1} now see the nametag as the player's actual name

set player's default nametag to "gold" #All players except for {_p1} now see the nametag as gold

reset player's nametag for {_p1} #{_p1} now sees the nametag as gold

set player's default nametag to "iron" for {_p1} #{_p1} now sees the nametag as iron

reset player's nametag #All players (including {_p1}) now see the nametag as the player's actual name

애드온을 적용했는데도 안되는데요?ㅠㅠㅠㅠ

코드 보여주시고,
MundoSk애드온은 1.12버전에서 업데이트가 중단됐습니다.
혹여나 Skript2.5 버전과 맞지 않을 수 있습니다. 1.12버전 스크립트는 Skript 2.2-dev37가 마지막입니다.
Skript 2.2-dev37으로도 확인해보시기 바랍니다.

on damage:

type of victim is wither:

set {데미지.%attacker%} to damage

add {데미지.%attacker%} to {누적데미지.%attacker%}

if {누적데미지.%attacker%} is 100:

set {칭호 :: %attacker%} to "[실버]"

message " -칭호 : [중급]" to attacker

give 1 iron sword to attacker

set player's default nametag to "[실버]"

command /test.nametag:
    trigger:
        set player's default nametag to "[실버]" 

이렇게 nametag만 적용해도 안되나요?

스크립트 버전을 바꿔서 했느데 다른 구문들이 실행이 안되네요 type of victim is wither 구문이 Can't compare an entity type with a potion다며 실해이안되네요
