本文介绍了一个Unity中的视频播放控制器实现，包括视频的播放、暂停、停止、切换上下视频及进度控制等功能。通过代码示例展示了如何使用Unity的VideoPlayer组件结合UI控件实现这些功能。

unity videoplay视频播放控制、进度条

废话不多说直接上代码，部分代码是借用了别人的写法，加上自己的认识做了修改基本上能满足日常的视频播放需要。

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Video;

public class VideoController : MonoBehaviour
{
//设置VideoPlayer、RawImage和当前播放视频索引参数
public VideoPlayer videoPlayer;
public RawImage rawImage;
private int currentClipIndex;
//设置相关文本和按钮参数以及视频列表
public Text text_PlayOrPause;
public Button button_PlayOrPause;
public Button button_Pre;
public Button button_stop;
public Button button_Next;
public VideoClip[] videoClips;
public Slider MVSlkder;

void Start()
{
    //获取VideoPlayer和RawImage组件，以及初始化当前视频索引
    //videoPlayer = this.GetComponent<VideoPlayer>();
   /// rawImage = this.GetComponent<RawImage>();
    currentClipIndex = 0;
    //设置相关按钮监听事件
    MVSlkder.onValueChanged.AddListener(delegate { OnMVSlkder(); });
   
    button_PlayOrPause.onClick.AddListener(OnPlayOrPauseVideo);
    button_stop.onClick.AddListener(Onstop);
