第一步、先申请一个声网账号
[Agora官网链接](https://console.shengwang.cn/)
第二步在官网创建项目 ,选择无证书模式,证书模式需要tokenh和Appld才能通话
第三步 官网下载SDK 然后导入到unity,也可以直接在unity商店里下载,Agora官网下载链接
第四步 运行官方Demo
1、导入后会有这些文件
2、从官网新建的项目复制AppID,粘贴到这个位置,如果使用的是证书模式,Token也需要填写,否者运行报错110,第三个变量是频道,可以自定义, ,Examples里的场景都是Demo,
3、找到这个场景,这个是语音通话的Demo场景
按照以上步骤,这是运行,就可以实现语音通话了,
如果运行有显示110等错误码,可以查看官网的解决方法,

声网每个月有一万分钟免费时长,非常赞
也可以按照官方文档去实现语音通话,文档写的非常清楚,代码都有,我按照吧官方文档的代码粘贴到一个脚本里,运行完全没问题,
上脚本(外加了一些回调事件的补充),

}// 实现你自己的回调类,可以继承 IRtcEngineEventHandler 接口类实现。

脚本使用方法,新建一个场景,以及搭两个按钮,和一个滑动框,把脚本随便挂载一个物体身上即可,
ContentSizeFitter可以让UI随文字自适应
然后运行,点击加入频道,打包PC包,在另一台电脑运行,也点击加入频道。
以下是运行效果,如果另外一台也加入频道,上面会显示远端用户加入频道,
