我终于可以看到逆时针旋转了
原图我只能看出顺时针旋转，当把所有帧反转后（帧频不变的情况下）可以看到两种旋转或交替出现。点击图片反转所有帧，把帧频调低有利于观察。
this.stage.frameRate = 17;
rate.text = "17 fps";
thumb.addEventListener(MouseEvent.MOUSE_DOWN, starter);
thumb.addEventListener(MouseEvent.MOUSE_UP, stopper);
thumb.addEventListener(MouseEvent.MOUSE_OUT, stopper);
thumb.addEventListener(MouseEvent.MOUSE_MOVE, mover);
function starter(args:Event) {
thumb.startDrag(false, new Rectangle(track.x, thumb.y, track.width, 0));
}
function stopper(args:Event) {
thumb.stopDrag();
}
function mover(args:Event) {
if (thumb.x>=track.x) {
var dist:Number = (thumb.x - track.x) / (track.width + track.x);
//trace(dist);
this.stage.frameRate = Math.round(dist*200);
rate.text = Math.round(dist*200).toString() + " fps";
}
}
var isre:Boolean=false;
function rplayer(event:MouseEvent):void {
if(isre==false) mc.gotoAndPlay("reverse");
else mc.gotoAndPlay("normal")
isre=!isre;
}
mc.addEventListener(MouseEvent.CLICK, rplayer);
