从另一个类nodejs获取新对象

Question

好的，我有一个包含

对象JS

var GameServer = require("./GameServer");
var gameServer = new GameServer();

GameServer()包含

GameServer JS

function GameServer() {
    // Startup
    this.run = true;
    this.lastNodeId = 1;
    this.lastPlayerId = 1;
    this.clients = [];
    this.largestClient; // Required for spectators
    this.nodes = [];
    this.nodesVirus = []; // Virus nodes
    this.nodesEjected = []; // Ejected mass nodes
    this.nodesPlayer = []; // Nodes controlled by players
}

现在，我想要的是从gameServer那里得到ObjectClass

在我的课堂上我试过

新JS

var ObjectClass = require("./ObjectClass");
var gameServer = ObjectClass.gameServer;

但是通过这种方式，我将无法获取类GameServer()属性。我刚开始接触节点，很抱歉我要问这个问题。我现在被困住了

当我试图从GameServer抓取客户端时

var ObjectClass = require("./ObjectClass");
var gameServer = ObjectClass.gameServer;
gameServer.clients.length;

我搞错了，客户还没有定义。有办法绕过这事吗？

我不能修改GameServer或对象js.。简单地说，我把一个脚本附加到一个脚本上，以获得额外的功能。

您丢失了文件的导出，因此在执行“要求(文件)”时，要获取和空对象{}。

对于gameServer，您应该执行如下操作：

'use strict';
function GameServer() {
    // Startup
    this.run = true;
    this.lastNodeId = 1;
    this.lastPlayerId = 1;
    this.clients = [];
    this.largestClient; // Required for spectators
    this.nodes = [];
    this.nodesVirus = []; // Virus nodes
    this.nodesEjected = []; // Ejected mass nodes
    this.nodesPlayer = []; // Nodes controlled by players
}

module.exports =  exports = GameServer;

ObjectClass

'use strict';
var GameServer = require("./GameServer");
var gameServer = new GameServer();
exports.gameServer = gameServer;

您需要理解需要缓存文件返回的值，因此您将使用gameServer的单例。
