다른 VX 따라다니기 스크립트를 써봤는데 제 컴에서 오류 없이 작동 되는 것은 이것 뿐이더군요.

사용하려면 손을 대야하는 부분만 번역하여 올려봅니다. 출처

저 같은 생초보 분들을 위해서 사족을 붙이자면... 밑에

  CATERPILLAR_HIDE_SWITCH = 1
  # 따라다니기용 스위치를 작성하고 동료 없이 다니려면 해당 스위치를 ON 하세요.
  # 동료가 따라다니게 하고 싶으면 스위치를 OFF 로 설정하세요

라는 부분이 있는데 "따라다니기용 스위치"는

이벤트 작성 -> 이벤트 커맨드 탭1 -> 스위치 조작 -> 단독 에서 (...) 클릭 ->

사용하지 않는 스위치 하나 정하고 알아보기 쉽게 표기 -> 해당 스위치 아이디 기억 (예: 0001)

->CATERPILLAR_HIDE_SWITCH =   옆 에다가 숫자를 씁니다.

예를 들어 0023 에다가 정했으면 CATERPILLAR_HIDE_SWITCH = 23 이라고 입력합니다.

동료가 따라다니게 하고 싶은 화면에다가 투명 이벤트 하나를 만들고 해당 스위치를 OFF 시켜놓습니다.

(껐다 키면 스위치가 리셋 되는 지는 잘 모르겠네요... 저는 아무데서나 저장 못하게 되어 있어서

저장할 수 있는 화면 (즉 로드되는 화면) 마다 이벤트를 만들고 스위치 OFF 하게 놨습니다.)
