数十枚、数百枚の画像を読み込む代わりに、flvから切り分ければ使える、というのはやったことがなかったのでやってみた。
ロード直後の一回は、flvを再生しながら、bitmap_arrayにbitmapを溜め込んでいる。
その後は角度に応じて、bitmap_arrayからbitmapを引き出してdrawしている。

var bm1:BitmapData = new BitmapData(160,120); bm1.draw(video_obj); bitmap_array.push(new Bitmap(bm1)); |
テストでは180、360枚でも問題なかったが、今回は、30fps,3秒、90枚の画像にした。目玉の動きはそこまで細かく分ける必要が無い、というのと、撮影する時にゆっくりスムーズに目玉を動かすのが難しかった、というのが主な理由。
