我有以下代码:
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);
}
});
当我尝试运行它时,我收到此错误:
Assets/SocketIO/SocketIOScript.cs(59,23): error CS1593: Delegate `System.Action' does not take `1' arguments
然而,当我删除这部分时:
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;
}
它运作得很好。
我想知道为什么会发生这种情况,我一直试图弄明白这一点。我找到了关于它的this帖子,但这对我没什么帮助,因为我不会认为我可以指定data
。
编辑:
StringToVector3
包含以下代码(但即使我摆脱了StringToVector3
,我仍然会收到错误):
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;
}
答案 0 :(得分:0)
问题是我需要使用System.Array.IndexOf
而不是userArr.IndexOf
