Unity中Websocket的简单使用-创新互联
首先我们需要一个websocket服务器,之前的博文中有做
Tomcat架设简单Websocket服务器
用的时候打开就行了,先不管它
Unity中新建场景
建UI(UGUI)
有一个连接按钮Button
一个信息输入框InputField
一个发送按钮Button
一个断开按钮Button
一个消息显示框Text
(猜你喜欢:Unity 连接WebSocket(ws://)服务器的方法)
场景中建一个GameObject,在上面加个脚本,就叫WSMgr好了
用到了BestHTTP这个插件
(猜你喜欢:在Unity3d下如何使用WebSocket)
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using BestHTTP;
using BestHTTP.WebSocket;
using System;
using BestHTTP.Examples;
using UnityEngine.UI;
using System.Text;
public class WSMgr : MonoBehaviour {
//public string url = "ws://localhost:8080/web1/websocket";
public string url = "ws://localhost:8080/web1/ws";
public InputField msg;
public Text console;
private WebSocket webSocket;
private void Start()
{
init();
}
private void init()
{
webSocket = new WebSocket(new Uri(url));
webSocket.OnOpen += OnOpen;
webSocket.OnMessage += OnMessageReceived;
webSocket.OnError += OnError;
webSocket.OnClosed += OnClosed;
}
private void antiInit()
{
webSocket.OnOpen = null;
webSocket.OnMessage = null;
webSocket.OnError = null;
webSocket.OnClosed = null;
webSocket = null;
}
private void setConsoleMsg(string msg)
{
console.text = "Message: " + msg;
}
public void Connect()
{
webSocket.Open();
}
private byte[] getBytes(string message)
{
byte[] buffer = Encoding.Default.GetBytes(message);
return buffer;
}
public void Send()
{
webSocket.Send(msg.text);
}
public void Send(string str)
{
webSocket.Send(str);
}
public void Close()
{
webSocket.Close();
}
#region WebSocket Event Handlers
///
/// Called when the web socket is open, and we are ready to send and receive data
///
void OnOpen(WebSocket ws)
{
Debug.Log("connected");
setConsoleMsg("Connected");
}
///
/// Called when we received a text message from the server
///
void OnMessageReceived(WebSocket ws, string message)
{
Debug.Log(message);
setConsoleMsg(message);
}
///
/// Called when the web socket closed
///
void OnClosed(WebSocket ws, UInt16 code, string message)
{
Debug.Log(message);
setConsoleMsg(message);
antiInit();
init();
}
private void OnDestroy()
{
if(webSocket!=null && webSocket.IsOpen)
{
webSocket.Close();
antiInit();
}
}
///
/// Called when an error occured on client side
///
void OnError(WebSocket ws, Exception ex)
{
string errorMsg = string.Empty;
#if !UNITY_WEBGL || UNITY_EDITOR
if (ws.InternalRequest.Response != null)
errorMsg = string.Format("Status Code from Server: {0} and Message: {1}", ws.InternalRequest.Response.StatusCode, ws.InternalRequest.Response.Message);
#endif
Debug.Log(errorMsg);
setConsoleMsg(errorMsg);
antiInit();
init();
}
#endregion
}
Connect Send Close 三个方法对应的就是三个按钮的功能
OnOpen OnMessage OnError OnClose这四个一看就是Websocket的四个事件对应的方法
首先在Start方法中init()
点击Connect,连接
在输入框中输入,点击Send就发送
点击Close断开连接
底部的Text中会显示消息
同样,Tomcat服务端也有显示
发布WebGL测试可用
