腾讯云 技术升级10大核心产品年终让利>>>   

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,

 10             If you're wondering why we embed each script separately, and not just the single-file phaser lib  11             it's because it makes debugging *significantly* easier for us. Feel free to replace all the below  12             with just a call to ../dist/phaser.js instead if you prefer.  13         -->

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
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 }
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,
