Visual Script와 Version Control 충돌문제

참고> Unity 2022  버전 이후로는 나타나지 않는 문제입니다.

Machine 추가시 Versiion Control과의 충돌 경고

 

이는 Unity에 기본적으로 설치된 "Version Control" 기능과 충돌이 나기 때문입니다.

이를 해결하기 위해서는 Version Control을 제거(Remove)하면 됩니다.

Version Control은 Unity "Collaborate" 기능과 "Plastic SCM"을 이용하는 것과 관련이 됩니다. 위 기능을 이미 아시는 분이라면 스스로 판단하시면 되지만 그렇지 않다면 사용할 일이 없을 듯 합니다. 게임 또는 앱을 만드는 유니티 본연의 기능과는 무관하고 팀작업을하거나 파일 관리를 지원하는 것인데 대부분 git이나 SVN을 사용할 가능성이 높고 개인 프로젝트라면 굳이 필요치 않습니다. 과감히 삭제하셔도 무관합니다.

 

"Unity > Window > Package Manager"에서 Version Control을 찾아 우측 하단의 "Remove"버튼을 눌러 제거해주세요.

 

 

유니티가 업데이트되면서 언젠가는 위 문제가 해결이 되지 않을까 싶습니다.
