1 环境结构

版本号Cocos2d-html5-v2.2，tomcat7.0

构造tomcat。然后直接解压Cocos2d-html5-v2.2.zip。解压后根文件访问的文件夹index.html你可以看到demo

2 cocos2d-html5文件夹结构简单说明

以samples\games\FruitAttack这个游戏为例

index.html：主页面

cocos2d.js:配置文件，这里能够载入.js文件

main.js：程序的主入口（之所以叫main.js这个名，是在\cocos2d\platform\jsloader.js 中配置的）

3 调试js代码，输出log

1 输出log

火狐浏览器，f12调出控制台。能够在代码中用

var i = 'I am a string';

console.log('变量：', i);

2 输出alert

alert("alert");

3 debug

能够在调试器中查看代码并加断点跟踪代码

4 基本代码实现触屏。主循环，绘制

GameLayer.js 游戏的主类。包括主循环，按键，触屏操作

GameData.js 游戏的资源类。直接用的demo的，没有进行删减

//var gNotification = cc.NotificationCenter.getInstance();

var gSpriteFrameCache = cc.SpriteFrameCache.getInstance();

var gSharedEngine = cc.AudioEngine.getInstance();

var MUSIC_BACKGROUND  = "audio/musicByFoxSynergy.mp3";

var EFFECT_BUTTON_CHICK  = "audio/effect_buttonClick.ogg";

var EFFECT_GAME_FAIL  = "audio/effect_game_fail.ogg";

var EFFECT_GAME_WIN  = "audio/effect_game_pass.ogg";

var EFFECT_PATTERN_UN_SWAP  = "audio/effect_unswap.ogg";

var EFFECT_PATTERN_CLEAR  = "audio/effect_clearPattern.ogg";

var EFFECT_PATTERN_BOMB  = "audio/effect_bombPattern.ogg";

var EFFECT_TIME_WARN  = "audio/effect_timewarning.ogg";

var g_ressources = [

    {src:"res/background.jpg"},

    {src:"res/logo.png"},

    {src:"res/btn/btnStartGameDown.png"},

    {src:"res/btn/btnStartGameNor.png"},

    {src:"res/ProgressBarFront.png"},

    {src:"res/ProgressBarBack.png"},

    {src:"res/baseResource.png"} ,

    {src:"res/baseResource.plist"},

    {src:"res/PatternBg.png"},

    {src:"resultLayer/star.png"},

    {src:"resultLayer/btnResultRestart.png"},

    {src:"resultLayer/btnResultRestartDown.png"},

    {src:MUSIC_BACKGROUND},

    {src:EFFECT_BUTTON_CHICK},

    {src:EFFECT_GAME_FAIL},

    {src:EFFECT_GAME_WIN},

    {src:EFFECT_PATTERN_UN_SWAP},

    {src:EFFECT_PATTERN_CLEAR},

    {src:EFFECT_PATTERN_BOMB},

    {src:EFFECT_TIME_WARN}

];

var gScoreData = {lastScore:0,bestScore:0};

var eGameMode = {

    Invalid : -1,

    Challenge:0,

    Timer:1,

    Count:2

};

var gGameMode = eGameMode.Challenge;

gScoreData.setLastScore = function(score){

    this.lastScore = score;

    if (score > this.bestScore)

    {

        this.bestScore = score;

        sys.localStorage.setItem('bestScore',this.bestScore);

    }

    sys.localStorage.setItem('lastScore',this.lastScore);

};

gScoreData.initData = function(){

    if( sys.localStorage.getItem('gameData') == null){

        sys.localStorage.setItem('bestScore','0');

        sys.localStorage.setItem('lastScore','0');

        sys.localStorage.setItem('gameData',33) ;

        return;

    }

    this.bestScore = parseInt(sys.localStorage.getItem('bestScore'));

};

5 触屏方法

触屏方法是加在layer类的子类中

首先，在init中增加触屏权限，这里仅仅加触屏，还能够加键盘，鼠标的权限（注意权限要加在this.scheduleUpdate()前,否则会有触屏方法不起作用）

if (sys.capabilities.hasOwnProperty('touches'))

               this.setTouchEnabled(true);

然后。就能够继承并覆盖触屏方法

onTouchesMoved:function (touches, event) {

        //this.processEvent(touches[0]);

},

onTouchesEnded:function(touches, event){

		console.log('touch end!!!');

        //this.processTouchEndEvent(touches[0].getLocation());

},

processTouchEndEvent:function(pos) {//接收一个位置

	this.logoSprite.setPosition(pos);

},

processEvent:function(event) {

        var delta = event.getDelta();//移动量

	var curPos = this.logoSprite.getPosition();

	curPos= cc.pAdd(curPos, delta);//当前位置+移动位置

	curPos= cc.pClamp(curPos, cc.POINT_ZERO, cc.p(this._size.width, this._size.height));

	this.logoSprite.setPosition(curPos);

},

6 接入box2d

1 引入box2d.js
