构建测试

MacOS 没问题

Android 试了一下，场景没问题，操作混乱

安卓导出参考AR Foundation笔记01 安卓Setup

目前的操作方式针对电脑，手机端以后再看要不要做

WebGL 整了半天

参考WebGL Export in Unity 2020

成功发布到itch.io，但是靠近显示介绍没有了？

本地Firefox打开，也没有

WebGL Debug

Unity里跑没问题

Debug.Log人物和画的距离，可以显示，所以可能是

UI显示出了问题

文字没有赋值成功

位置偏了

给Text设了默认值，再试

默认值显示了

靠近没有了

所以应该是位置不对
