html5游戏引擎-Pharse.js学习笔记（一）

1.前言

　　前几天随着flappy bird这样的小游戏的火爆，使我这种也曾了解过html5技术的js业余爱好者也开始关注游戏开发。研究过两个个比较成熟的html5游戏引擎，感觉用引擎还是要方便一些。所以决定从今天正式开始研究html5游戏引擎，并且将从看官网demo的学习整理成博客和大家一起分享。

　　我了解过cocos-2d for html5和phaser.js这两个引擎，其中前者比较复杂，对于有过cocos-2d平台开发经验的人来说可能学习的较为容易一些，如果是纯入门汉又不想研究c++版本（因为c++版本的网上资料较多）的，感觉学习难度较大。而第二种则相对来说demo详细，虽然没有文档是一大遗憾，但是感觉相对还是比较容易，所以就作为自己的今天的学习方向了。。所不定以后哪一天要是开发出flappy bird这样的游戏，那就真的逆袭了。。。

　　自己也是初学者，主要的学习方式就是去github的项目主页（

/photonstorm/phaser

）下载demo进行学习，开发工具是装了aptana插件的eclipse for jee的最新版。

　　好了，现在开始demo学习第一课。

2.引入插件

　　把src拷贝进项目就可以了，如果发布的话就用phaser.min.js一个文件就行了，

3.加载一个图片，移动动画，响应点击事件

/** *  */var game = new Phaser.Game(800, 600, Phaser.CANVAS, 'phaser-example', { preload: preload, create: create });function preload() {    //  You can fill the preloader with as many assets as your game requires    //  Here we are loading an image. The first parameter is the unique    //  string by which we'll identify the image later in our code.    //  The second parameter is the URL of the image (relative)    game.load.image('einstein', 'assets/pics/ra_einstein.png');}function create() {    //  This creates a simple sprite that is using our loaded image and    //  displays it on-screen    var image=game.add.sprite(0, 0, 'einstein');    image.body.velocity.x=50;    image.inputEnabled=true;    image.events.onInputDown.add(listener,this);    }function listener(){    alert('clicked');}01-03.js01-03.js

4.尝试

　　设置断点查看生命周期。在生命周期方法中加上debugger;语句强制断点。

/** *  */var game = new Phaser.Game(800, 600, Phaser.CANVAS, 'phaser-example', { preload: preload, create: create,update:update,render:render });function preload() {    //  You can fill the preloader with as many assets as your game requires    //  Here we are loading an image. The first parameter is the unique    //  string by which we'll identify the image later in our code.    //  The second parameter is the URL of the image (relative)    game.load.image('einstein', 'assets/pics/ra_einstein.png');    debugger;}function create() {    //  This creates a simple sprite that is using our loaded image and    //  displays it on-screen    var image=game.add.sprite(0, 0, 'einstein');//    image.body.velocity.x=50;    image.inputEnabled=true;    image.events.onInputDown.add(listener,this);        debugger;}function listener(){    alert('clicked');}function update(){    debugger;}function render () {    //debug helper    game.debug.renderInputInfo(32,32);    debugger;}01-03.js加断点

经过实验可以看出调用方法：preload(加载资源),create(创建对象和其他初始化工作),update和render方法在每次渲染时都会调用

通过这个简单的例子可以让我们对phaser.js框架有个大概的了解，
