Slider控制脚本，使用进度条控制视频进度,挂在给Slider

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;

public class SliderChange : MonoBehaviour, IDragHandler,IPointerClickHandler
{
    //拖动改变视频进度
    public void OnDrag(PointerEventData eventData)
    {
        VideoCtrl.instance.ChangeVideo(VideoCtrl.instance.sliderVideo.value);
    }
    //点击改变视频进度
    public void OnPointerClick(PointerEventData eventData)
    {
        VideoCtrl.instance.ChangeVideo(VideoCtrl.instance.sliderVideo.value);
    }
}

在WebGL上如果不能播放，可能是让它开始时自动播放了，需要手动点击播放
还是Edge浏览器牛批
