체력바를 플레이어의 자식으로 들어가게 하니까 플레이어의 scale에 영향을 받아서 제가 원하던 크기가 나오지가 않아요 ㅠㅠ일일이 하드 코딩으로 맞춰주기에는 나중에 이런 비슷한 일이 생기면 어떡하지 싶기도 한데...혹시 하위 자식으로 들어가더라도 들어 가기전의 스케일을 유지하는 방법 있을까요?아무래도 scale이 비율이다 보니까 자식으로 들어가기 전 크기가 1,1,1 이고 들어가고 나서도 1,1,1 이라고 해도 영향을 받더라구요!ㅠㅠ위치는 영향을 받지만 크기만 영향을 받지 않게 하고 싶은데 도무지 모르겠네요...

안녕하세요!혼자 복습 해보다가 얼떨결에 시도해본 방법인데, 매개변수에@RequestBody를 선언해주고, 포스트맨에서 Body쪽에 값을 넘겨주었는데 에러가 떴습니다.그리고 @RequestBody를 제거한 뒤에, 포스트맨에서는 Param쪽에 값을 넘겨주니 작동이 됐습니다.전 그동안 연습하면서 controller 쪽에 값을 받아올 때는 @RequestBody / @RequestParam / @PathVariable셋중 하나 반드시 넣어줘야 한다고 배웠었는데요. 강의에서 아무것도 선언해주지 않아야 작동 되는 것을 보고 크게 혼란이 왔습니다.강의의 경우 포스트맨에서 쿼리스트링으로 값을 받아오고 있으니 @RequestParam을 넣어줘야 하지 않나요? 이것도 넣으면 마찬가지로 에러가 뜹니다. 왜 그런건가요??

안녕하세요 강의 잘보고있습니다9분30초 까지 영상을 보고 DFS(3)에 Breakpoint 로 하나하나 보고있다가 3,0,1,2 까지 실행되고 더이상 실행이 안되는게 맞는거같은데 DFS(next) 재귀함수로 돌아오더라고요 이게 이해가 잘안되는데 어떻게 가능한건가요?

최상위에 index.html / css / images / js / html 폴더들을 놓고 html폴더 > common폴더 > header.html / footer.html을 넣어둔 뒤 index.html에서 include하면 적용이 안됩니다ㅠㅠindex와 header.html, footer.html 이 같은 레벨에 있을 때만 적용이 되는데 어떻게 해야할까요?load 하려는 html과 불러오려는 html이 같은 레벨에 있을때만 적용이 되는걸까요??

=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요? 예2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? 네3. 질문 잘하기 메뉴얼을 읽어보셨나요? 예[질문 내용]List<Member> result = em.createQuery("select m from Member as m",Member.class) .getResultList();위 내용을 설명하시면서 JPA는 절대 테이블 대상으로 쿼리를 짜지 않으며, 따라서 select m from Member as m의 Member는 객체이다. 라고 설명하셨는데 이해가 잘 안돼요...from 뒤의 Member가 테이블의 Member가 아니라는 이야기겠죠? 그럼 @Entity로 관리되는 Member클래스를 말하나요? 테이블을 가리키는게 아니면 JPA는 어떻게 수많은 테이블중 Member테이블을 콕 찝어서 쿼리를 넘기나요? 엔티티명과 테이블명이 같아서,,,인가요? 근데 제 머리가 이해하기로는 form Member의 Member가 테이블명이여서, Member테이블의 모든내용을 가져와 m, 즉 Member객체에 집어넣는다고 이해가되거든요. 만약 저 Member가 엔티티객체라면... 엔티티객체엔 아무것도 없는데 거기다가 select m을 한다고해서 결과가 뜰수가 있는건가요...ㅜㅜ

강의 중 비쥬얼스튜디오에서 베릴로그 환경 설정하는 법을 알려주신다고 하였는데 언제 강의를 볼 수 있을지 궁금합니다.

const reduce = curry((f, acc, iter) => { if (!iter) return reduce(f, head((iter = acc[Symbol.iterator]())), iter); iter = iter[Symbol.iterator](); return go1(acc, function recur(acc) { let cur; while (!(cur = iter.next()).done) { /* acc = reduceF(acc, cur.value, f); */ const a = cur.value; acc = a instanceof Promise ? a.then( (a) => f(acc, a), (e) => (e === nop ? acc : Promise.reject(e)) ) : f(acc, a); if (acc instanceof Promise) return acc.then(recur); } return acc; }); });이렇게 실행하면Uncaught (in promise) TypeError: Chaining cycle detected for promise #<Promise>위와 같이 순환참조 오류가 발생하는데 이렇게 발생하는 이유가 아래와 같은 순서로 인해 발생하는게 맞는지 확인좀 부탁드립니다...acc에 a.then메서드가 호출된 결과로 이때 pending 상태의 Promise 객체가 할당됨 a.then메서드의 콜백함수가 실행되며 1번의 pending상태의 Promise객체가 리턴 pending상태이기 때문에 settled상태가 아니며 프로미스 체이닝이 불가능 하고 프로미스를 사용 할 수 없는 무한정 대기상태에 빠짐 프로미스 다루는게 무진장 어렵다는것을 한 강의 한 강의 마다 느낍니다...

[질문 내용]강의 중 6:03에서 쿼리를 짤 필요가 없이 JDBC에서 제공하는 방식을 사용하셨는데쿼리대신 JDBC에서 제공하는 방식을 사용하는 이유가 있나요??공식문서를 찾아보니DBC 드라이버를 통해 검색할 수 있는 데이터베이스 메타데이터를 활용하여 단순화된 구성을 제공함으로 코드에 모든 세부 정보를 제공하려는 경우 메타데이터 처리를 재정의하거나 끌 수 있지만 미리 구성할 항목이 적습니다.라고 나오는데이러한 장점때문일까요??

코드가 이해가 안되는 것이 아니라 수학적인 원리를 모르고있습니다.왜 15-3 = 1212%2 == 012/2 = 61+6, 2+6 즉 7,8로 가능하다는 결론이 나오는 수학적인 원리가 무엇인가요?그냥 공식이 그런것이니 외우면 되는 것일까요?

게임 제작에 있어 저렇게 프로그래밍 할 이유가 있나요? 그니까 애초에 저렇게 변환을 할 이유가 뭐가 있나요?정확하지 않고 오버되는 값은 다 분실되는데 저렇게 하면 망하지 않나요..?

선생님 안녕하세요! 자바 강의부터 디자인패턴 강의까지 선생님의 수업으로 많은 것을 배우고 있는 수강생입니다. 선생님의 디자인패턴 강의를 복습차 정리하여 개인 블로그에 올려도 괜찮을지 문의드립니다. 허락하신다면, 강의에서 배운 디자인패턴 내용을 제가 이해한 부분 중심으로 정리하고, 예시코드 일부를 함께 게시하려고 합니다! (해당 강의 링크를 출처로 기재하겠습니다)혹시 강의 자료와 내용의 저작권과 관련된 문제가 생길 수 있다면 게시하지 않겠습니다!

이렇게 map을 사용하는게.. dbms안쓰려고 코드에 작성한거잖아요?그럼 저 map을 인메모리 디비라고 하나요..?저 map을 뭐라부르는..거죠..?

안녕하세요 맛비님.별 다른 질문은 아니고, 예전부터 궁금했던 것인데위 사진에서 40번째줄에 r_valid <= {LATENCY{1'b0}};부분을 왜 저렇게 표현했는지 궁금합니다.r_valid <= 0; 이렇게 해도 LATENCY가 달라짐에 따라 0의 값이 고정이지 않나요??위에서 localparam LATENCY = 2 라고 해서 40번째 줄은 r_valid <= {2{1'b0}}; 와 같습니다. ( 2{1'b0} = 2*1'b0 = 2'b0 인건가요? )

학습하는 분들께 도움이 되고, 더 좋은 답변을 드릴 수 있도록 질문전에 다음을 꼭 확인해주세요.1. 강의 내용과 관련된 질문을 남겨주세요.2. 인프런의 질문 게시판과 자주 하는 질문(링크)을 먼저 확인해주세요.(자주 하는 질문 링크: https://bit.ly/3fX6ygx)3. 질문 잘하기 메뉴얼(링크)을 먼저 읽어주세요.(질문 잘하기 메뉴얼 링크: https://bit.ly/2UfeqCG)질문 시에는 위 내용은 삭제하고 다음 내용을 남겨주세요.=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요?

리프래시 토큰이 기간 만료되었다는 거는 어플 쪽에서 확인을 해서 재발급 요청을 보내야 하나요?예를 들어서 페이로드에 있는 만료일을 어플 백그라운드에서 계속 체크하면서 만료되면 재발급 요청을 서버쪽에 보내는 건지 궁금 합니다.액세스토큰이 만료일 때 리프레시 토큰까지 만료이면 바로 로그아웃인데 리프래시 토큰만 만료인 경우는 어떻게 검증하는지 궁금합니다

[제로초 강좌 질문 필독 사항입니다]질문에는 여러분에게 도움이 되는 질문과 도움이 되지 않는 질문이 있습니다.도움이 되는 질문을 하는 방법을 알려드립니다.https://www.youtube.com/watch?v=PUKOWrOuC0c0. 숫자 0부터 시작한 이유는 1보다 더 중요한 것이기 때문입니다. 에러가 났을 때 해결을 하는 게 중요한 게 아닙니다. 왜 여러분은 해결을 못 하고 저는 해결을 하는지, 어디서 힌트를 얻은 것이고 어떻게 해결한 건지 그걸 알아가셔야 합니다. 그렇지 못한 질문은 무의미한 질문입니다.1. 에러 메시지를 올리기 전에 반드시 스스로 번역을 해야 합니다. 번역기 요즘 잘 되어 있습니다. 에러 메시지가 에러 해결 단서의 90%를 차지합니다. 한글로 번역만 해도 대부분 풀립니다. 그냥 에러메시지를 올리고(심지어 안 올리는 분도 있습니다. 저는 독심술사가 아닙니다) 해결해달라고 하시면 아무런 도움이 안 됩니다.2. 에러 메시지를 잘라서 올리지 않아야 합니다. 입문자일수록 에러메시지에서 어떤 부분이 가장 중요한 부분인지 모르실 겁니다. 그러니 통째로 올리셔야 합니다.3. 코드도 같이 올려주세요. 다만 코드 전체를 다 올리거나, 깃헙 주소만 띡 던지지는 마세요. 여러분이 "가장" 의심스럽다고 생각하는 코드를 올려주세요.4. 이 강좌를 바탕으로 여러분이 응용을 해보다가 막히는 부분, 여러 개의 선택지 중에서 조언이 필요한 부분, 제 경험이 궁금한 부분에 대한 질문은 대환영입니다. 다만 여러분의 회사 일은 질문하지 마세요.5. 강좌 하나 끝날 때마다 남의 질문들을 읽어보세요. 여러분이 곧 만나게 될 에러들입니다.6. 위에 적은 내용을 명심하지 않으시면 백날 강좌를 봐도(제 강좌가 아니더라도) 실력이 늘지 않고 그냥 코딩쇼 관람 및 한컴타자연습을 한 셈이 될 겁니다.    안녕하세요! 1-5 Promise.all 과 for of 문의 차이 강의 듣고 궁금한 점이 생겨서 질문드립니다!Promise.all 이 동시에 진행되어 속도가 빠른 대신 순서가 보장되지 않는다고 하셨고 for of는 순서대로 요청을 보내고 응답을 받기 때문에 속도가 좀 느리다고 하셨는데현업에서 많은 양의 데이터를 순서대로 크롤링 해야하는 경우에 Promise.all로 빠르게 크롤링 데이터를 받아와서 정렬을 하는게 나은가요 아니면 for of로 느리더라도 순서대로 데이터를 받아오는게 나은가요?
