이런 코드인데 HotReload만 하면 변수가 전부 초기화됨

BreakPoint 넣어봤는데 HotReload하기 전/ 후 저 함수들을 부르는 행위 자체가 없었음

왜 초기화될까..? HotReload 진짜 못써먹겠네

(근데 코드 올리는 방식을 두가지로 해봤는데 뭐가 더 보기좋음?)

2번째가 더 잘보이네

근데 짤려

[글쓴 ㅇㅇ(211.55)]

디스코드에 물어보니깐 HotReload 버그있다고 Live Coding 쓰라는데 근데 이거도 버그 많으니깐 그냥 껏다키는게 좋긴하데

[글쓴 ㅇㅇ(211.55)]

알고있긴 했는데 뭔가 더 거지같네 HotReload

[글쓴 ㅇㅇ(211.55)]

DO NOT DISABLE LIVE CODING. disabling live coding enables hot reload. hot reload corrupts assets. turn live coding back on. For UE5 only: go into editor settings and search for Reinstancing. turn this off (uncheck it). Reinstancing also corrupts assets. UE4 doesn't have Reinstancing.

[글쓴 ㅇㅇ(211.55)]

Any time you edit a .h file, close the editor and build+run from your IDE Any time you edit a constructor function, close the editor and build+run from your IDE When editing other existing functions in .cpp files, you can try live coding (ctrl+alt+F11) Always open your project from your IDE (build and run, or build and run with debugging)

reinstancing도 꺼래 에디터 메뉴에서

ide에서컴파일했을때 간혹 엔진에서 ㅈㄹ날때있음 엔진에 컴파일버튼 눌러주면 좀 나음 - dc App

제 경우는 가끔이 아니라 그냥 무조건이여서
