我正在使用socket.io和nodejs制作一个游戏，我正在制作一个名为rooms.js的模块，该模块需要使用
rooms.js：
users.js模块和fiveSocket.js模块。但是当我从主服务器文件中调用Rooms.New时，它会显示fiveSocket未定义，当Rooms.New调用users.js函数时，我得到了TypeError: Cannot read property 'getSocketIDbyId' of undefined的错误。
rooms.js：
var mysql = require('../mysql/mysql.js');
var headers = require('./headers.js');
var users = require('./users.js');
var fiveSocket = require('./sockets.js');
var Rooms = {
Obj: {},
Room: function(data) {
var room = this;
this.name = data.name;
this.users = [];
this.floorCode = data.floor;
this.description = data.desc;
this.maxUsers = data.maxUsers;
this.owner = data.owner;
this.setTime = new Date().getTime();
this.dbID = data.dbID;
this.doorx = data.doorx;
this.doory = data.doory;
this.doordir = data.doordir;
},
New: function(socketID, roomID) {
var keys = Object.keys(Rooms.Obj).length;
var id = keys + 1;
var callback = function(row) {
fiveSocket.emitClient(socketID, headers.roomData, {
title: row.title,
desc: row.description,
mapStr: row.floorCode,
doorx: row.doorx,
doory: row.doory,
doordir: row.doordir
});
var uid = users.getIdBySocketID(socketID);
users.Obj[uid].curRoom = roomID;
var rid = Rooms.getIdByDbID(roomID);
Rooms.Obj[rid].users.push(uid);
}
if(Rooms.getIdByDbID(roomID) != false) {
var room = Rooms.getIdByDbID(roomID);
var row = { title: room.name, description: room.description, floorCode: room.foorCode, doorx: room.doorx, doory: room.doory, doordir: room.doordir };
callback(row);
} else {
mysql.Query('SELECT * FROM rooms WHERE id = ? LIMIT 1', roomID, function(rows) {
if(rows.length > 0) {
var row = rows[0];
Rooms.Obj[id] = new Rooms.Room({name: row.title, floorCode: row.floorCode, desc: row.description, maxUsers: row.maxUsers, owner: row.owner, dbID: row.id, doorx: row.doorx, doory: row.doory, doordir: row.doordir});
callback(row);
}
});
}
},
removeUser: function(DBroomID, userID) {
var rid = Rooms.getIdByDbID(DBroomID);
var room = Rooms.Obj[rid];
var index = room.indexOf(userID);
if (index > -1) array.splice(index, 1);
},
Listener: function(users) {
setInterval(function(){
for(var roomID in Rooms.Obj) {
var room = Rooms.Obj[roomID];
// send users coordinates
room.users.forEach(function(uid) {
var socketID = users.getSocketIDbyId(uid);
var data = Rooms.getUsersInRoomData(roomID);
fiveSocket.emitClient(socketID, headers.roomUsers, data);
});
// unload inactive rooms (no users after 10 seconds)
var activeUsers = room.users.length;
var timestamp = room.setTime;
var t = new Date(); t.setSeconds(t.getSeconds() + 10);
var time2 = t.getTime();
if(activeUsers <= 0 && timestamp < time2) {
Rooms.Remove(roomID);
}
}
}, 1);
},
getUsersInRoomData: function(roomID) {
var room = Rooms.Obj[roomID];
var obj = {};
room.users.forEach(function(uid) {
var user = users.Obj[uid];
obj[uid] = {
username: user.username,
position: user.position,
figure: user.figure
};
});
return obj;
},
Remove: function(id) {
delete Rooms.Obj[id];
},
getIdByDbID: function(dbID) {
var result = null;
for(var room in Rooms.Obj) {
var u = Rooms.Obj[room];
if(u.dbID == dbID) var result = room;
}
if(result == null) return false;
else return result;
},
getDbIDbyId: function(id) {
return Rooms.Obj[id].dbID;
}
}
Rooms.Listener();
module.exports = Rooms;
编辑：（如果有帮助的话）
当我在主文件中使用console.log fiveSocket时
当我在rooms.js文件中使用console.log fiveSocket时
编辑2：当我从
fiveSocket中删除var users = require（'./users.js'）;，当我在rooms.js中使用console.log它可以工作，为什么？
编辑3：我仍然有问题
如果您需要其他模块源代码：
Users.JS： http://pastebin.com/Ynq9Qvi7
sockets.JS http://pastebin.com/wpmbKeAA
fiveSockets.js中移除了var users = require('./users.js');后，当我在rooms.js中使用console.log时它是起作用的，为什么？ - user5672329
