[LayaAirIDE 1.0]关于movieClip播放swf的问题

let emotionSwf: Laya.MovieClip = new Laya.MovieClip();
let emotionAltasPath =
emotionSwf.load(emotionSwfPath, true, emotionAltasPath);
emotionSwf.play(0,false);
emotionSwf.playTo(0, emotionSwf.count, Laya.Handler.create(this,() => {
emotionSwf.stop();
emotion.visible = false;
}));
如上代码，发现调研play(0,false)后，动画还是一直循环播放，还是emotionSwf.count一直为0，导致播放完成的回调会立即执行，请问该如何解决？？？
