[Unreal] [Editor] Unreal Plugin 제작 방법

Plugin Start

Unreal plugin 시작방법 예제이다.

 

1. 메뉴바 -> 편집 -> 플러그인

 

2. 오른쪽 하단 새 플러그인 클릭

3. 에디터 툴바를 사용하는 "에디터 툴바 버튼"으로 플러그인 생성 (MyPlugin)

 

4. 프로젝트 재시작 시 에디터 툴바에 MyPlugin을 확인할 수 있음

 

5. 플러그인 소스는 visual studio 프로젝트에서 수정할 수 있음

이부분을 통해 모듈 초기화 함수가 정의되고, 모듈의 초기 세팅이 수행된다.
