我有一些代码，我只是试图在两个客户都提出答案时运行。这些是函数finish和datarequest（）;。
目前，我有它正确地等待两个响应并且在一个客户端回答之后不发出。问题在于它没有达到我的if语句。
有没有办法让++ nrecieved ++;根据客户给出的答案类型。即。两个错误答案，两个正确答案或每个答案中的一个？基本上是让它运行nrecieved ++;基于客户的一致反应？
var nrecieved = 0;
var responses = {}; // Socket id to response
function finish(){
// Loop through users in game and send them their responses
for(var id in responses){
if(responses.hasOwnProperty(id)){
// Send the response
io.to(id).emit('updatePlayer', responses[id]);
}
}
}
socket.on('playerCorrect', function (data) {
nrecieved++;
responses[socket.id] = data;
answerValidation(nrecieved);
});
socket.on('playerWrong', function (data) {
nrecieved++;
responses[socket.id] = data;
answerValidation(nrecieved);
});
console.log(nrecieved);
function answerValidation(value) {
nrecieved = value + value;
console.log(value);
if(nrecieved == 2){
finish();
dataRequest();
}
}

尝试创建自己的对象，存储用户及其套接字及其答案。
以下是您的存储空间的示例：
var socketStorage = {
roomname : {
some-socketid : { // the socket id from socket.id
username : "username", // the username of the user
socket : socket, // the socket of the user
currQuestion : { // an object representing the current question
answered : false,
answer : false
},
allQuestionsAnswers : [ true, true, true ] // an array of answers
},
some-socketid : {
// the socket id from socket.id
username : "otherusername",
socket : socket,
currQuestion : {
answered : false,
answer : false
},
allQuestionsAnswers : [ true, true, false ]
},
}
};
以下是您如何使用此对象：
var socketStorage = {};
io.sockets.on("connection",function(socket){
var roomName = "gamelobby"; // ideally generate a unique room where 2 sockets would join
socketStorage[roomName] = {};
socketStorage[roomName][socket.id] = {
username : "username",
socket : socket,
currQuestion : {
answered : false,
answer : false
},
allQuestionsAnswers : []
};
})
理想情况下，让用户向您发送他的信息（例如用户名），例如：
socket.emit("setusername", {username:"my-awesome-username"});
并在服务器上以这种方式在存储中设置用户名：
socket.on("setusername", function(msg){
socketStorage[roomName][socket.id].username = msg.usename;
})
这是一个简单的工作示例：
客户方：
socket.on("connect",function(){
// Joining the game
socket.emit('joingame', {username:"foobar"});
$(document).on('click', '.answerButton' , function(){
function answerChecker(element){
if(element == gaPosition) {
correctAnswer();
}
else {
console.log("Incorrect!");
incorrectAnswer();
}
}
var clickedButton = $(this).data('button');
console.log(clickedButton);
answerChecker(clickedButton);
});
function correctAnswer() {
var correct = true;
socket.emit('playercorrect', {answer: true});
console.log(correct);
buttonRemover();
}
// Check if wrong + send to server
function incorrectAnswer () {
var wrong = false;
socket.emit('playerwrong', {answer: false});
buttonRemover();
}
socket.on("updateplayer", function(data){
if (data.answer === true) {
console.log ('Player got it right! ' + data.answer);
} else if (data.answer === false) {
console.log ('Player got it wrong! ' + data.answer);
}
})
socket.on("gamefinished", function(data){
console.log(data.message);
});
})
服务器端：
var users = {}, validQuestions = [], validCurrQuestion = [];
io.sockets.on('connection', function(socket){
socket.on("joingame", function(msg){
console.log("joining game");
users[socket.id] = {responses:[],currQuestion: {answered:false,answer:null}};
socket.on("playercorrect",function(msg){
users[socket.id].currQuestion.answered = true:
users[socket.id].currQuestion.answer = true:
users[socket.id].responses.push(msg.answer);
checkAnswers(socket);
})
socket.on("playerwrong",function(msg){
users[socket.id].currQuestion.answered = true:
users[socket.id].currQuestion.answer = false:
users[socket.id].responses.push(msg.answer);
checkAnswers(socket);
})
})
})
io.sockets.on('disconnect', function(socket){
delete users[socket.id];
})
function checkAnswers(socket){
var connectedC = Object.keys(users).length;
for (var clientK in users) {
// check if current q has been answered
if(users[clientK].currQuestion.answered) {
validCurrQuestion.push({socket:socket,answer:users[clientK].currQuestion.answer});
if (validCurrQuestion.length === connectedC) {
// curr question answered by both clients
// send result to both
sendCurrQresults();
}
}
// if the 8 questions have been answered
// push into array
if (users[clientK].responses.length === 8) {
validQuestions.push(socket.id);
}
// if all users have answered all question send game results
if (validQuestions.length === connectedC) {
// finish the game
getWinner()
}
}
}
function sendCurrQresults(){
validCurrQuestion.forEach(function(question, index){
question.socket.emit("updateplayer", {answer: question.answer});
// reset curr question to go to next question
validCurrQuestion.splice(index, 1);
users[socket.id].currQuestion = { answered: false, answer: null};
})
}
function getWinner(){
// Check who has more true response and send by counting user.responses true vs false
}
