您好我正在尝试使用 UNet 设置通过浏览器播放的多人游戏。在编辑器中一切正常，我按照教程（https://www.youtube.com/watch?v=qGkkaNkq8co）说它应该在 webgl 中工作，但遗憾的是它没有。目前有两个脚本，一个用于客户端，一个用于下面链接的服务器。这主要使用 LLAPI。
我是否使用 networkServer.usewebsocket = true 结果是一样的。
“完成连接”的调试确实显示，因此它完成了 OnConnection 功能。
从编辑器一切正常，但从浏览器我收到以下错误：
“尝试发送到未连接的连接 {1}”——因为我在询问 ASKNAME 和询问 ASKPOSITION 时收到此错误，所以我怀疑 SEND 函数是我试图发送浏览器无法理解的内容的问题。但我不知道为什么。

任何反馈都将不胜感激，我已经尝试过查看文档，但我觉得我已经完成了它所说的所有事情（https://docs.unity3d.com/Manual/UNetUsingTransport.html）在它谈话的底部关于 webgl 支持，但它似乎没有奏效。
非常感谢您。
