Вставляем в classpath
запускаем аналогично

var tm2:TransitionManager = new TransitionManager(drawRect(new Rectangle(0,30,300,30),0xFF6600));
tm2.startTransition({type:AsyncBlinds, fps:50, direction:Transition.IN, duration:4, easing:Bounce.easeOut, numStrips:30, dimension:1});
не забыть про параметр fps, куда нужно вписать текущий fps .
щас думаю над вопросом авто определения. |
