[해결완료]아이템 클래스 제한 스크립트에 대해서 질문있습니다.

돈으로 주고 스킬북 사는 시스템을 구현하던 중

직업제한이 필요한 것 같아서 구글링으로 찾은 스크립트인데요

사용은 문제가 없는데

다른 것 사용해서 튕기는지는 실험하지 못했습니다만

전투 중에 힐을 하면 튕기네요

 

Script 'item class' line 113: NoMethodError occurred.

undefined method 'include?' for nil:NilClass

요렇게 뜨면서 꺼집니다.

뭔 말인진 알겠는데 스크립트 건드릴 줄도 모르고

어떻게 고치는 줄도 모르겠어서 질문드립니다.

아무리 구글에 검색해도 오류나 따로 나오는 건 없네요

밑은 스크립트 전문입니다.
