Unity2021+Vuforia物体识别实现视频播放控制

1.插入3D面板当做视频播放的载体，再更换材质为ImageTarget中对应的照片，再添加视频组件，指定视频文件

2.在Plane下添加UI世界级窗口，再添加按钮控制视频播放

3.代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Video;
 
public class AudioMP4 : MonoBehaviour
{
    public VideoPlayer video;
    public Button button;
 
    //播放
    public void OnPlayer()
    {
        if (!video.isPlaying)
        {
            video.Play();
            //隐藏按钮
            button.gameObject.SetActive(false);
        }
    }
    //停止
    public void OnPause()
    {
        if (video.isPlaying)
        {
            video.Pause();
            //显示按钮
            button.gameObject.SetActive(true);
        }
    }
 
    //按键控制播放或者暂停
 
    private void updata() {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            if (video.isPlaying)
            {
                video.Pause();
                //显示按钮
                button.gameObject.SetActive(true);
            }
            else
            {
                video.Play();
                //隐藏按钮
                button.gameObject.SetActive(false);
            }
        }
