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（https://github.com/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.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。
1 /** 2 * 3 */ 4 5 var game = new Phaser.Game(800, 600, Phaser.CANVAS, 'phaser-example', { preload: preload, create: create,update:update,render:render }); 6 7 function preload() { 8 9 // You can fill the preloader with as many assets as your game requires 10 11 // Here we are loading an image. The first parameter is the unique 12 // string by which we'll identify the image later in our code. 13 14 // The second parameter is the URL of the image (relative) 15 game.load.image('einstein', 'assets/pics/ra_einstein.png'); 16 17 debugger; 18 } 19 20 function create() { 21 22 // This creates a simple sprite that is using our loaded image and 23 // displays it on-screen 24 var image=game.add.sprite(0, 0, 'einstein'); 25 // image.body.velocity.x=50; 26 image.inputEnabled=true; 27 28 image.events.onInputDown.add(listener,this); 29 30 debugger; 31 } 32 33 function listener(){ 34 alert('clicked'); 35 } 36 function update(){ 37 debugger; 38 } 39 function render () { 40 //debug helper 41 game.debug.renderInputInfo(32,32); 42 debugger; 43 }
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，
