我有以下代码:统一:委托`System.Action”不采取'1' 参数
socket.On ("chat", (data) => {
string str = data.ToString();
ChatData chat = JsonConvert.DeserializeObject<ChatData> (str);
string strChatLog = "user#" + chat.id + ": " + chat.msg;
int pos = userArr.IndexOf (chat.id);
if (pos > -1) {
var InsObj = Instantiate (player, StringToVector3 (chat.msg), Quaternion.identity);
InsObj.name = chat.id;
userArr [userArr.Length + 1] = chat.id;
}
// Access to Unity UI is not allowed in a background thread, so let's put into a shared variable
lock (chatLog) {
chatLog.Add (strChatLog);
}
});
当我尝试运行它,我得到这个错误:
Assets/SocketIO/SocketIOScript.cs(59,23): error CS1593: Delegate `System.Action' does not take `1' arguments
然而当我删除此部分:
int pos = userArr.IndexOf (chat.id);
if (pos > -1) {
var InsObj = Instantiate (player, StringToVector3 (chat.msg), Quaternion.identity);
InsObj.name = chat.id;
userArr [userArr.Length + 1] = chat.id;
}
它工作得很好。
我想知道为什么会发生这种情况,我一直在试图弄清楚它的一段时间。我发现this后有关它,但这并没有多大帮助,因为我不认为,我可以指定data
。
编辑:
StringToVector3
包含下面的代码(但是即使我摆脱StringToVector3
我仍然得到错误):
public static Vector3 StringToVector3 (string sVector)
{
// Remove the parentheses
if (sVector.StartsWith ("(") && sVector.EndsWith (")")) {
sVector = sVector.Substring (1, sVector.Length - 2);
}
// split the items
string[] sArray = sVector.Split (',');
// store as a Vector3
Vector3 result = new Vector3 (
float.Parse (sArray [0]),
float.Parse (sArray [1]),
float.Parse (sArray [2]));
return result;
}
什么是StringToVector3?看起来你正在调用一个带'void'返回类型的函数,或者一个'Action' – Rob
我已经添加了'StringToVector3',但是如果我排除它,我仍然会得到相同的错误。感谢您的帮助! – pudility
'StringToVector3'已经返回一个'Vector3' - 你真的需要将它传递给构造函数吗?你可以写:'Instantiate(player,StringToVector3(chat.msg),Quaternion.identity);' – Rob
