Question

我基本上想要一个70秒的倒数计时器，重置为70，这是一个infinte倒数计时器。计时器重新启动时，新游戏开始。唯一的问题是，如果我把计数器放在IO.on（连接）中，新的计时器启动时，新的计时器启动，然后计时器混乱，因为它需要在所有客户端（Android应用程序）上显示完全相同的计时器。我尝试将设置间隔设置在io.on之上，但它不会每秒更新只给出一个单值

下面是我的服务器代码

var app = require('express')();
var server = require('http').Server(app);
var io = require('socket.io')(server);
var mysql = require('mysql');
var players = [];
var wingames ;
var db = mysql.createConnection({
    host: 'localhost',
    user: 'vaibhav_spinner',
    database: 'spinapi',

})
var newGameid = 1;
db.connect(function(err){
    if (err) console.log(err)
})
server.listen(11694, function(){
    console.log("Server is now running...");
});
  var countdown = 70;


///
io.on('connection', function(socket){
    console.log("Player Connected!");
if(players.length==1){
  var countdown = 70;

var countdowner =    setInterval(function() {
    countdown--;
  io.sockets.emit('timer', { countdown: countdown });
  socket.emit('lastwins',wingames);
  console.log(countdown);
if (countdown==0) {
  console.log("starting game");
  countdown = 70;
  newGameid ++;
  console.log(newGameid);


}


}, 1000);

}

    socket.emit('getPlayers', players);
  socket.emit('newgameid',{newgame: newGameid});
    socket.broadcast.emit('newPlayer', { id: socket.id });
    socket.on('disconnect', function(){
        console.log("Player Disconnected");
        socket.broadcast.emit('playerDisconnected', { id: socket.id });
        for(var i = 0; i < players.length; i++){
            if(players[i].id == socket.id){
                players.splice(i, 1);
            }
        }
    });



  socket.on('getcoins',function(data){
    var email = data.uname;
  console.log(" userEamil "+email);

   db.query("SELECT * FROM userinfo WHERE uemail =  ?",[email] ,function (err, result, fields) {
     if(err) throw err;

     console.log(result);
    var ecoin = result[0].uCoins;
   console.log(" userCoins "+ecoin)
   io.emit('ucoins', ecoin);
  }); });




  socket.on('updatecoins',function(data){
    console.log("data= "+data.toString());
    var email = data.uname;
    var ucoins = data.ucoins;
  console.log(" userEmail "+email,"ucoins"+ucoins);

   db.query("UPDATE userinfo set uCoins = ? WHERE uemail = ?",[ucoins,email],function (err, result, fields) {
     if(err) throw err;

     console.log(result.affectedRows + " record(s) updated");
   });

 });

 // socket.on('getwinner',winnerbet(){
 //
 // });



    players.push(new player(socket.id, 0, 0));

});

function player(id, x, y){
    this.id = id;
    this.x = x;
    this.y = y;
}

我尝试了这样的方法：如果players.length == 1那么计时器应该启动而不是所有连接。但仍然无法使其正确。我的android端代码正确获取所以我没有问题wi 那个

Socket IO中的倒计时器对所有客户端都是相同的
