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samplesgamesFruitAttack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cocos2dplatformjsloader.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

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);
