-1
我有以下代碼:統一:委託`System.Action」不採取'1' 參數
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);
}
});
當我嘗試運行它,我得到這個錯誤:
Assets/SocketIO/SocketIOScript.cs(59,23): error CS1593: Delegate `System.Action' does not take `1' arguments
然而當我刪除此部分:
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。
我想知道爲什麼會發生這種情況,我一直在試圖弄清楚它的一段時間。我發現this後有關它,但這並沒有多大幫助,因爲我不認爲,我可以指定data
。
編輯:
StringToVector3
包含下面的代碼(但是即使我擺脫StringToVector3
我仍然得到錯誤):
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;
}
什麼是StringToVector3?看起來你正在調用一個帶'void'返回類型的函數,或者一個'Action' – Rob
我已經添加了'StringToVector3',但是如果我排除它,我仍然會得到相同的錯誤。感謝您的幫助! – pudility
'StringToVector3'已經返回一個'Vector3' - 你真的需要將它傳遞給構造函數嗎?你可以寫:'Instantiate(player,StringToVector3(chat.msg),Quaternion.identity);' – Rob
