使用來自其他線程的統一API或調用主線程中的函數我的問題是，我試圖使用UnitySocket來實現一些東西。每次，當我收到一條新消息時，我需要將它更新為更新文本(它是一個統一文本)。但是，當我執行以下代碼時，無效更新并不是每次都調用。我不包括updatetext.GetComponent<Text>().text = "From server: "+tempMesg;在voidgetInformation中，這個函數在線程中，當我在getInformation()中包含這個函數時，它會出現一個錯誤：getcomponentfastpath can only be called from the main thread我想問題是我不知道如何在C#中一起運行主線程和子線程？或許還有其他問題.。希望有人能幫忙.。這是我的密碼：using UnityEngine;using System.Collections;using System;using System.Net.Sockets;using System.Text;using System.Threading;using UnityEngine.
UI;public class Client : MonoBehaviour {
System.Net.Sockets.TcpClient clientSocket = new System.Net.Sockets.TcpClient();
private Thread oThread;// for UI update
public GameObject updatetext;
String tempMesg = "Waiting...";
// Use this for initialization
void Start () {
updatetext.GetComponent<Text>().text = "Waiting...";
clientSocket.Connect("10.132.198.29", 8888);
oThread = new Thread (new ThreadStart (getInformation));
oThread.Start ();
Debug.Log ("Running the client");
}
// Update is called once per frame
void Update () {
updatetext.GetComponent<Text>().text = "From server: "+tempMesg;
Debug.Log (tempMesg);
}
void getInformation(){
while (true) {
try {
NetworkStream networkStream = clientSocket.GetStream ();
byte[] bytesFrom = new byte[10025];
networkStream.Read (bytesFrom, 0, (int)bytesFrom.Length);
string dataFromClient = System.Text.Encoding.ASCII.GetString (bytesFrom);
dataFromClient = dataFromClient.Substring (0, dataFromClient.IndexOf ("$"));
Debug.Log (" >> Data from Server - " + dataFromClient);
tempMesg = dataFromClient;
string serverResponse = "Last Message from Server" + dataFromClient;
