Question

好的，所以我有一个动画图表，同时动画多个线条和形状。一旦用户播放动画，我希望他/她能够暂停并且整个事情停止，然后当用户再次点击播放按钮时再次开始。我不应该需要一个循环来执行此操作，因为它应该在每次单击鼠标时执行此操作。这是代码示例。

var tween = new Kinetic.Tween({
    node: lineTween,
    points: [563.965, 258.163, 604.272, 258.163],
    duration: 2
});

var tween3 = new Kinetic.Tween({
    node: path3,
    points: [582.81, 257.901, 582.81, 214.216],
    duration: 2,
    onFinish: function(){
        tween3a.play();
    }
});

document.getElementById('play').addEventListener('click', function(){
    tween.play(
    setTimeout(function(){
        tween3.play();
    }, 1000)
    );
}, false);

document.getElementById('pause').addEventListener('click', function(){
    tween.pause();
}, false);

有人有任何建议吗？
