    /// </summary>

    private void SetVideoTimeValueChange()
    {

    }

    // 当前视频的总时间值和当前播放时间值的参数
    private int currentHour;
    private int currentMinute;
    private int currentSecond;
    private int clipHour;
    private int clipMinute;
    private int clipSecond;

}

目录结构：

RawImage挂载组件：

以下是上图组件具体内容：

滑动条Slider的具体：

脚本中拖入RawImage

using UnityEngine;

using UnityEngine.EventSystems;
/// <summary>
/// 继承 拖拽接口
/// </summary>
public class SliderEvent : MonoBehaviour, IDragHandler
{
    [SerializeField]
    private ToPlayVideo toPlayVideo;        // 视频播放的脚本

    /// <summary>
    /// 给 Slider 添加 拖拽事件
    /// </summary>
    /// <param name="eventData"></param>

    public void OnDrag(PointerEventData eventData)
    {
        SetVideoTimeValueChange();
    }

    /// <summary>
    /// 当前的 Slider 比例值转换为当前的视频播放时间
    /// </summary>
    private void SetVideoTimeValueChange()
    {
        toPlayVideo.videoPlayer.time = toPlayVideo.videoTimeSlider.value * toPlayVideo.videoPlayer.clip.length;
    }

}

Button按钮控制暂停/播放：

这个我用的是动态加载的img，首先播放的时候是出来“暂停”的模样，当按下后动态加载“播放”样子的img

资源放在

一步步按着来，最终就成功啦。
