Unity Vuforia播放视频全过程（从Unity的安装到打包）
一、安装Unity
（1）点击安装地址下载Unity Hub
下载好之后点击安装。
（2）从Unity Hub进去安装Unity（要先注册登陆账号）
安装完后是这样的
二、新建项目
项目创建完成打开如下：
目标平台为安卓平台，选择菜单file—>buildsetting
三、项目制作
（1）在Unity内导入vuforia engine
window—>package manager
（2）前往Vuforia注册登录账号
点击Vuforia前往官网
注册登陆之后：
创建应用
（3）上传识别图
（4）下载到Unity
（5）将下载好的文件放置进入Unity（手动拖就好）
（6）按想法（识别图片播放视频）制作工程
在此窗口点击鼠标右键
依次点击Vuforia Engine—>AR Camera
在此窗口继续鼠标右键
依次点击Vuforia Engine—>Image
（7）配置密钥
回到AR Camera，点击open vuforia engine configuration
回到Vuforia官网
将框内密钥复制进入Unity
将AR Camera的下图脚本移除（remove component）
返回至ImageTarget，将下图脚本移除：
创建脚本：
脚本代码如下：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

OnTrackingLost();
}

}
}

// Disable canvas':
foreach (var component in canvasComponents)

panel.SetActive(false);
}
#endregion // PROTECTED_METHODS
}
（8）编辑设置页面（使用VideoPlayer播放视频）
选中ImageTarget，鼠标右键—>UI—>Canvas
选中Canvas，鼠标右键—>Video—>VideoPlayer
选中VideoPlayer，更改分辨率大小，并添加RawImage
创建Render Texture
右键Asset—>Greate—>Render Texture
选中Render Texture，更改分辨率
赋值给VideoPlayer和RawImage
（9）将要播放的视频放入工程（手动拖拽就好）
将Canvas隐藏，并将Canvas赋值给脚本TestAR（手动拖拽）
Ctrl+S保存项目，点击如下按钮运行：
将识别图放入摄像头识别区内即可播放视频
四、项目打包
菜单栏file—>buildsetting
将场景添加（手动拖拽）
点击build
至此打包完成。
