【Unity】代码控制视频的播放（视频播放器）

这个老版本的可以借鉴，新版的已经出来了，上链接哈：

【Unity】代码控制视频的播放（视频播放器-更新）_夜梦说开发（VR）的博客-CSDN博客

结果如上图。。。

如图所示，里面有开始，暂停，重播，关闭按钮，同时有一个播放视频的进度条，以及后面两个显示时间总长度和实时时间的文本，以及中间播放视频的RawImage。

上一次写了如何设置RawImage进行自动播放，这次就直接用代码控制，同时还有进度条的控制。

可以看一下上一次的这篇文章：

CSDNhttps://mp.csdn.net/mp_blog/creation/editor/120648989

在写代码之前，还需要把按钮和组件相对的设置好，以及RawImage的设置调整好

using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.Video;
 using UnityEngine.UI;
 using UnityEngine.EventSystems;
 using System;public class VideoCrol : MonoBehaviour {public static VideoCrol instance;private VideoPlayer vPlayer;public GameObject videoImage;//播放imageprivate Button BtnPlay, BtnPause, BtnReStart;//开始，暂停，重播public Slider sliderVideo;//进度条private Button BtnX;//关闭private Image VideoPanel;//视频背景private Text NowTime;//播放时间private Text TotalTime;//总时间private float tt;//视频总时长private float Index_t;//进度条计时时间private float hour, min, second;private bool IsPlay = true;void Awake(){instance = this;vPlayer = videoImage.GetComponent();BtnPlay = GameObject.Find("Kaishi").GetComponent();BtnPause = GameObject.Find("Zanting").GetComponent();BtnReStart = GameObject.Find("ReWindButton").GetComponent();sliderVideo = GameObject.Find("SliderVideo").GetComponent();VideoPanel = GameObject.Find("VideoPanel").GetComponent();BtnX = GameObject.Find("CloseButton").GetComponent();TotalTime = GameObject.Find("ZongTimeText").GetComponent();NowTime = GameObject.Find("NowTimeText").GetComponent();}public void OnEnable(){BtnReStart.onClick.AddListener(ClickReStart);BtnReStart.onClick.AddListener(ClickReStart);BtnX.onClick.AddListener(ClickBtnX);BtnPlay.onClick.AddListener(ClickKaishi);BtnPause.onClick.AddListener(ClickZanting);}public void OnDisable(){BtnReStart.onClick.RemoveListener(ClickReStart);BtnReStart.onClick.RemoveListener(ClickReStart);BtnX.onClick.RemoveListener(ClickBtnX);BtnPlay.onClick.RemoveListener(ClickKaishi);BtnPause.onClick.RemoveListener(ClickZanting);}// Use this for initializationvoid Start () {ClickKaishi();//是否自动播放tt = (float)vPlayer.clip.length;sliderVideo.maxValue = tt;min = (int)tt / 60;second = (int)tt % 60;TotalTime.text = string.Format("{0:D2}:{1:D2}",min.ToString(),second.ToString());}void Update () {//播放if (IsPlay){vPlayer.Play();Index_t += Time.deltaTime;if (Index_t>=0.1f){sliderVideo.value += 0.1f;Index_t = 0;}}else{vPlayer.Pause();}//进度条到底停止播放if (sliderVideo.maxValue-sliderVideo.value<=0.1f){ClickReStart();}ChangeTime((float)vPlayer.time);}public void ChangeVideo(float value){vPlayer.time = value;}/// 
/// 播放时间显示/// 
/// void ChangeTime(float value){min = (int)value / 60;second = (int)value % 60;NowTime.text= string.Format("{0:D2}:{1:D2}", min.ToString(), second.ToString());}/// 
/// 重播按钮/// 
public void ClickReStart(){sliderVideo.value = 0;vPlayer.time = 0;}/// 
/// 关闭按钮/// 
public void ClickBtnX(){VideoPanel.gameObject.SetActive(false);}/// 
/// 开始按钮/// 
public void ClickKaishi(){if (sliderVideo.value==sliderVideo.maxValue){sliderVideo.value = 0;}videoImage.SetActive(true);IsPlay = true;BtnPause.gameObject.SetActive(true);BtnPlay.gameObject.SetActive(false);}/// 
/// 暂停按钮/// 
public void ClickZanting(){IsPlay = false;BtnPause.gameObject.SetActive(false);BtnPlay.gameObject.SetActive(true);}
 }
 

同时还有另外一个脚本用来控制Slider的拖动和拖拽（两个接口，拖动和点击）

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){VideoCrol.instance.ChangeVideo(VideoCrol.instance.sliderVideo.value);}/// 
/// 点击改变视频进度/// 
/// public void OnPointerClick(PointerEventData eventData){VideoCrol.instance.ChangeVideo(VideoCrol.instance.sliderVideo.value);}
 }

在最后写完代码，组件做完之后，视频和参数等也需要调整一下

把整体打包了一个，包含代码和组件，可以看一下(上面的是打包好的网盘链接)

视频播放器更新了喇叭控制音量。
