1)代码
let websocket = cc.Class({extends: ponent,properties: {_sock: null,_services_handler: null,_msg_queue: [],is_lock: false,},onLoad: function () {},onDestroy: function () {console.log("onDestroy");},lock: function () {this.is_lock = true;},unlock: function () {this.is_lock = false;},update: function () {if (this.is_lock) {return;}if (this._msg_queue.length > 0) {// 从消息队列中取得一个消息let obj_data = this._msg_queue.shift();let ctype = obj_data.ctype;let body = obj_data.body;console.log("[", ctype, "]", body);if (this._services_handler[ctype]) {this._services_handler[ctype](ctype, body);} else {console.warn(ctype, "客户端没有注册!!!");}}},on_open: function () {console.log("连接服务器成功!!!");},on_message: function (event) {if (!this._services_handler) {return;}let obj_data = JSON.parse(event.data);this._msg_queue.push(obj_data);},on_close: function () {console.log("on_close!!!");this.close();},// 比如没有连上on_error: function () {console.log("on_error!!!");this.close();},close: function () {if (this._sock) {this._sock.close();this._sock = null;}},connect: function (url) {this._sock = new WebSocket(url);this._sock.binaryType = "arraybuffer";this._sock.onopen = this.on_open.bind(this);this._sock.onmessage = this.on_message.bind(this);this._sock.onclose = this.on_close.bind(this);this._sock.onerror = this.on_error.bind(this);},send_data: function (obj_data) {if (!this._sock || this._sock.readyState != WebSocket.OPEN) {console.error("尚未连接服务器!!!");return;}let json_data = JSON.stringify(obj_data);this._sock.send(json_data);},register_services_handler: function (services_handler) {this._services_handler = services_handler;},remove_services_handler: function () {this._services_handler = null;}});websocket._instance = null;websocket.getInstance = function () {if (!websocket._instance) {let node = new cc.Node();websocket._instance = node.addComponent(websocket);cc.game.addPersistRootNode(node);}return websocket._instance;};module.exports = websocket;
onLoad: function () {let services_handler = {};services_handler[cmd.NICKNAME_LOGIN_RES] = this.on_nickname_login_server_return.bind(this);websocket.getInstance().register_services_handler(services_handler);},onDestroy: function () {websocket.getInstance().remove_services_handler();},on_nickname_login_server_return: function (ctype, body) {if (body.errormsg) {return;}let nickname = body.nickname;// 暂存下玩家名字ugame.nickname = nickname;util.load_scene("main_scene");},
直接切换。在game_scene中监听，发现丢一条
预加载场景 则没问题(但是万一场景很大,所以不保险)
加锁，则没问题(推荐)
let websocket = require("websocket");let util = {load_scene: function (scene_name) {websocket.getInstance().lock();cc.director.loadScene(scene_name, function () {websocket.getInstance().unlock();});},};module.exports = util;
11号消息(开始游戏) 和 12号消息(轮到谁出牌) 之间切换了场景，但是依旧没事，是顺序的
