Flashを最後に使ったので、しばらくしてから、Actionscript 3を学ぶのが最善だと思っていました。しかし、私は[Flashビデオプレイヤーチュートリアル] [1]を手がかりにしています。私のニーズに合わせてレイアウトをカスタマイズしてください。Flash Actionscript 3.0 Videoplayerヘルプ
プログレスバーを13.9px右に55.8px移動しました。私はまた、プログレスバーを176.9pxに短縮しました。問題は、55.8pxで右に移動するスクラバーをクリックしたときです。スクラバーは55.8pxから始めるべきだと私は思う。誰かが自分のコードを見て、私が変更する必要があるものを提案してもらえますか？
種類よろしく、
