Flash를 마지막으로 사용한 이래로 Actionscript 3을 배우는 것이 가장 좋았습니다. 그러나 [Flash Videoplayer tutorial] [1]을 통해 작업하고 있었고 정말 고심하고 있습니다. 내 자신의 필요에 맞게 레이아웃을 변경하십시오.Flash Actionscript 3.0 Videoplayer help
진행률 표시 줄을 13.9 픽셀 아래로 이동하고 오른쪽으로 55.8 픽셀 이동했습니다. 진행률 막대를 176.9 픽셀로 줄였습니다. 문제는 내가 55.8px로 오른쪽으로 점프하는 스크러버를 클릭 할 때입니다. 내가 어딘가에 scrubber가 55.8px에서 시작해야한다고 알 필요가 있지만, 매번 내가 더 많은 문제를 일으키는 것을 시도한다. 누군가 제 코드를 살펴보고 변경해야 할 것이 무엇인지 제안 해주십시오.
친절 감사,
