结果如上图，之前写过一个使用代码控制视频播放器的Demo，但是好多小伙伴说我附带的链接没法下载，这次我直接做一个完整版的，不用下载，照着一步一步做就能做出来。

之前写了如何设置RawImage进行自动播放，大家可以看一下基础操作这篇文章：，大佬勿怪。

【Unity】在UI界面上显示播放视频_夜梦说开发（VR）的博客-CSDN博客

 

面板结构如上图。

Bg是背景，rawimage是视频播放图片以及播放器

主要组件Rawimage面板展示：

这次的功能有开始，暂停，重播，音量调节，时间显示，面板关闭，面板开启没有做，大家可以自由发挥。

上代码：

 这个是主要功能脚本，挂在外面的panel上。

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

/// <summary>
/// 挂载在进度条上
/// </summary>
public class SliderChange : MonoBehaviour,IDragHandler,IPointerClickHandler
{
    /// <summary>
    /// 拖动改变视频进度
    /// </summary>
    /// <param name="eventData"></param>
    public void OnDrag(PointerEventData eventData)
    {
        VideoCrol.instance.ChangeVideo(VideoCrol.instance.videoSlider.value);
    }

    /// <summary>
    /// 点击改变视频进度
    /// </summary>
    /// <param name="eventData"></param>
    public void OnPointerClick(PointerEventData eventData)
    {
        VideoCrol.instance.ChangeVideo(VideoCrol.instance.videoSlider.value);
    }
}

 这个是挂载在视频进度条上的slider，主要是为了让slider可以拖拽。

结果如下图：

 

 

代码有些长，大部分都是直接从外面挂载拖拽的，为了方便阅读，添加了注释，希望小白和想借鉴的朋友借鉴一下，UI自行更换哈。。。后面我会发一个打包链接

第二个链接是2019版的，还没上传完成，等后续补充一个。
