Unity VideoPlayer视频播放器，进度条滑动，视频时长显示

1.显示视频时长在text显示出来

timeText.text = string.Format("{0} / {1}", ToTimeFormat((float)videoplayer.time), ToTimeFormat((float)videoplayer.length));

//时长用00：00显示
    private string ToTimeFormat(float time)
    {
        int seconds = (int)time;
        int minutes = seconds / 60;
        seconds %= 60;
        return string.Format("{0:D2}:{1:D2}", minutes, seconds);
    }

2.滑动条跟着视频进度

progressSlider.value = (float)(videoplayer.time / videoplayer.length);

 3.拖动滑动条

// 开始拖动视频进度条
progressSlider.OnEventTriggerEvent(EventTriggerType.PointerDown, s => 
    {
         videoplayer.Stop();
         btn_Play.gameObject.SetActive(true);
         btn_Pause.gameObject.SetActive(false);
    });
//结束拖动视频进度条
progressSlider.OnEventTriggerEvent(EventTriggerType.PointerUp, s =>
    {
         btn_Play.gameObject.SetActive(false );
         btn_Pause.gameObject.SetActive(true);
         videoplayer.time = progressSlider.value * videoplayer.length;
         videoplayer.Play();
     });


public static class UIBehaviourExtension
{
    /// 

    /// 添加EventTrigger事件监听
    /// 
    /// 
    /// 
    /// 
    /// 
    /// 
    public static T OnEventTriggerEvent(this T self, EventTriggerType type, UnityAction action) where T : UIBehaviour
    {
        var eventTrigger = self.GetComponent() ?? self.gameObject.AddComponent();
        EventTrigger.Entry entry = new EventTrigger.Entry { eventID = type };
        entry.callback.AddListener(action);
        eventTrigger.triggers.Add(entry);
        return self;
    }
}
