Tweens가 스테이지에 추가되었지만 버튼 클릭에 응답하지 않았습니다.

Question

처음에는 볼 수 없도록 설정 한 4 개의 객관식 질문 (텍스트 필드가 포함 된 스프라이트)이 있습니다. 버튼을 클릭하면 표시되도록 설정 한 다음 올바른 대답 만 남긴 상태에서 알파 0으로 희미 해지기를 원합니다. 다음 코드는 이것을 수행하지만 addToStage 핸들러에서 initTweens()를 호출 할 때만 가능합니다. 버튼 클릭 이벤트 (playClickHandler)에서 호출하려고하면 알파 페이드가 발생하지 않습니다. 왜 누군가는 볼 수 있습니까?

감사합니다.

Answer 1

. 대신 선언시 인스턴스의

:

private var timeline:TimelineLite = new TimelineLite(); 

난 그냥 내가 다음() 함수 initTweens에서 인스턴스화

private var timeline:TimelineLite; 

했다. 그것은 트릭을했다. 어떤 이유로 타임 라인은 호출 될 때마다 선언 될 때 인스턴스화 된 덕분에 자동으로 실행됩니다.

Answer 2

문제는 playClickHandler(e:MouseEvent)에서라는 makeVisible() 함께. 댓글을 달거나 제거 할 경우 ADDED_TO_STAGE 이벤트와 동일한 방식으로 작동합니다.

이유는 AutoAlpha 플러그인이 사용자의 시야를 제어하기 때문에 makeVisible()을 호출 할 필요가 없기 때문입니다.
