这似乎是一个操作顺序问题，但我不知道我在哪里把事情搞砸了。我试图在按下按钮时从客户端发送消息到由客户端名称组成的服务器：
string msg = "TELLCLIENTNAME|" + playerName;
SendMsg(msg, reliableChannelID);
在服务器脚本上我有一个案例
case "TELLCLIENTNAME":
OnTellClientName(splitData[1], recConnectionID);
break;
查找字符串，一旦收到该字符串，我只想通过文字反馈向屏幕发送确认信息：
void OnTellClientName(string playerName, int cnnID) {
infoDisplayText.GetComponent<Text>().text += "Player Name : " + playerName + " on Connection ID : " + cnnID + "\n";}
很简单，但我没有让事情有效，我得到的错误是：
Attempt to send to not connected connection {1}
UnityEngine.Networking.NetworkTransport:Send(Int32, Int32, Int32, Byte[], Int32, Byte&)
Client:SendMsg(String, Int32) (at Assets/_Scripts/Networking/Client.cs:96)
Client:Connect() (at Assets/_Scripts/Networking/Client.cs:90)
UnityEngine.EventSystems.EventSystem:Update()
我在这里弄错了什么？
