如何使用我的游戏:

  • 用户点击停止,然后他们得到一个字母来创建一个比其他玩家更大的单词

  • 当用户输入一个单词,然后点击“提交”按钮并发送到服务器,服务器选择了更大的单词。。。还没做完

  • 在这里,我们必须允许使用socket.io进行两人游戏

  • 以下是单人游戏基本模式的代码:

    也在游戏中有一个实时聊天的玩家聊天

    app.js

    var app = require('express').createServer()
    var io = require('socket.io').listen(app);
    
    app.listen(8080);
    
    // routing
    app.get('/', function (req, res) {
      res.sendfile(__dirname + '/index.html');
    });
    
    // usernames which are currently connected to the chat
    var usernames = {};
    
    io.sockets.on('connection', function (socket) {
    
        // when the client emits 'sendchat', this listens and executes
        socket.on('sendchat', function (data) {
            // we tell the client to execute 'updatechat' with 2 parameters
            io.sockets.emit('updatechat', socket.username, data);
        });
    
        // when the client emits 'adduser', this listens and executes
        socket.on('adduser', function(username){
            // we store the username in the socket session for this client
            socket.username = username;
            // add the client's username to the global list
            usernames[username] = username;
            // echo to client they've connected
            socket.emit('updatechat', 'SERVER', 'you have connected');
            // echo globally (all clients) that a person has connected
            socket.broadcast.emit('updatechat', 'SERVER', username + ' has connected');
            // update the list of users in chat, client-side
            io.sockets.emit('updateusers', usernames);
        });
    
        // when the user disconnects.. perform this
        socket.on('disconnect', function(){
            // remove the username from global usernames list
            delete usernames[socket.username];
            // update list of users in chat, client-side
            io.sockets.emit('updateusers', usernames);
            // echo globally that this client has left
            socket.broadcast.emit('updatechat', 'SERVER', socket.username + ' has disconnected');
        });
    });
    
    和index.html

    <script>
        var socket = io.connect('http://localhost:8080');
    
        // on connection to server, ask for user's name with an anonymous callback
        socket.on('connect', function(){
            // call the server-side function 'adduser' and send one parameter (value of prompt)
            socket.emit('adduser', prompt("What's your name?"));
        });
    
        // listener, whenever the server emits 'updatechat', this updates the chat body
        socket.on('updatechat', function (username, data) {
            $('#conversation').append('<b>'+username + ':</b> ' + data + '<br>');
        });
    
        // listener, whenever the server emits 'updateusers', this updates the username list
        socket.on('updateusers', function(data) {
            $('#users').empty();
            $.each(data, function(key, value) {
                $('#users').append('<div>' + key + '</div>');
            });
        });
    
        // on load of page
        $(function(){
            // when the client clicks SEND
            $('#datasend').click( function() {
                var message = $('#data').val();
                $('#data').val('');

                if(e.which == 13) {
                    $(this).blur();

    现在我需要使用socket.io允许两人游戏中的字母进行实时聊天,我已经有了socket.io聊天,但是如何将socket.io实现到我的游戏代码中,我在上面的JSFIDLE中介绍了这一点

    请帮助理解socket.io游戏开发

    我认为这对于理解socket.io创建游戏来说一定是一个很好的教程。
    我想这里的很多人都会对这个问题感兴趣……

    你的问题很难理解,所以除了一般性的建议之外,我不太确定你想要什么

    我快速搜索了一下,找到了这个


    可能会有帮助?

    why-1 why…………好的,谢谢,但我认为这对许多人来说一定很有趣,因为他们想通过示例了解socket.io的工作原理。这不是一个真正的问题,建议您阅读常见问题解答。正如你们所问的,这个游戏和多用户客户端服务器无关。游戏内容相同,机制相同,聊天服务器是一个经典的例子…如何创建一个多层版本的这个;jsfiddle.net/9rtFa/12/witj实时连接和用户可能不是解决这个问题的好地方,我将删除himI jst。我不想允许多人游戏用于我的简单游戏jsfiddle.net/9rtFa/12/你不能只“允许”多人游戏。它必须被编程来处理多人互动。
