<>项目场景：
unity3d的发布，采用后台运行模式，发布后配置
本例采用2020.3.23f1c1 WEBGL
<>问题描述
unity3D默认情况下，依赖于界面的刷新，界面失去焦点，后台不运行，现实中，特别是实时展示前后台数据交互场景中，需要后台运行
设置后台运行：
File > Build Settings… > Player > Resolution and Presentation > Run In
Background* √ 设置选中。
*这个设置只在webgl和stand 起作⽤，ios不起作用
后台运行后，对CPU造成很大压力，采用如下方式解决：
在Start方法里边添加Application.targetFrameRate = 60;
File > Build Settings… >Quality>VSync Count 选择Dont Sync
发布后，需要对IIS进行配置，对应的web.config如下：
<?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer>
<staticContent> <mimeMap fileExtension=".unity3d"
mimeType="application/octet-stream" /> <mimeMap fileExtension=".unityweb"
mimeType="application/binary" /> </staticContent> </system.webServer>
</configuration>在这里插入代码片
