楼主记忆力不好，最近刚好用了一下createJs框架，怕以后一段时间没用后会忘记，所以在此做个记录，或许以后用得着。
createJs网上的中文教程挺少的，以前UC有个Xcanvas的论坛有createJs的详细教程，但是随着XCanvas团队的解散，那个网站也关闭了。。网上的大部分都是非常基础的教程，有点千遍一律的感觉。所以楼主就去把createJs下载下来，硬着头皮看英文文档了。凭着楼主这英语六级只考了三百多分的渣渣来说，看起来很费力啊，不过还是勉强摸索出了大概的用法。所以现在就是学了多少就记录多少，之后或许也会不定期更新一下该框架的新的学习心得。毕竟对自己以后还是有帮助的。
希望本文能帮到那些想学createJs的新手。因为楼主也是刚学的，所以本文或许有不正确之处，因此本文仅当参考，若有不正之处欢迎斧正。
闲话说到这，直接进入主题。
楼主用createJs写了个简单的跑酷游戏DEMO，就拿它做例子吧。 看DEMO戳我。
createJs的由来，基础什么的就不说了，就直接说createJs的用法吧。
首先到createJs官网下载，createJs分成easelJs（图形动画）、preloadJs（文件加载）、soundJs（音频控制）以及tweenJs（补间动画）四部分，大家下载的时候，建议下载两个文件，一个是压缩版文件，用于项目中的引用，再下载个源码文件，用于查看用法、API、demo等。因为楼主目前只用了easelJs和preloadJs，所以暂时就只说这两个，其实就这两个已经非常够用了。
接下来开始分析代码：
首先引入js文件
1.<script src='easeljs-0.7.1.min.js'></script>
2.<script src='preloadjs-0.4.1.min.js'></script>
然后进行舞台初始化操作：
01.function init(){
02.stage = new createjs.Stage('cas');
03.C_W = stage.canvas.width;
04.C_H = stage.canvas.height;
05.
06.var manifest = [
07.{src:'image/man.png' , id:'man'},
08.{src:'image/ground.png' , id:'ground'},
09.{src:'image/bg.png' , id:'bg'},
10.{src:'image/high.jpg' , id:'high'},
11.{src:'image/coins.png' , id:'coin'}
12.]
13.
14.loader = new createjs.LoadQueue(false);
15.loader.addEventListener('complete' , handleComplete);
16.loader.loadManifest(manifest);
17.
18.drawLoading();
19.}
上面就用到了preloadJs中的方法，实例化一个loader，把需要加载的图片文件放在manifest里面，进行加载，加载完成后调用回调handleCompelete函数：
01.function handleComplete(){ //当图片素材load完后执行该方法
02.var manImage = loader.getResult('man'),
03.lowground = loader.getResult('ground'),
04.highground = loader.getResult('high'),
05.bgImage = loader.getResult('bg'),
06.coins = loader.getResult('coin');
07.
08.sky = new createjs.Shape();
09.sky.graphics.bf(bgImage).drawRect(0,0,C_W,C_H);
10.sky.setTransform(0, 0, 1 , C_H/bgImage.height);
11.stage.addChild(sky);
12.
13.man = createMan(200,326,manImage);
14.
15.//该框为判定角色的判定区域
16.kuang = new createjs.Shape();
17.kuang.graphics.beginStroke('rgba(255,0,0,0.5)').drawRect(0 , 0 , man.size().w , man.picsize().h*1.5);
18.// stage.addChild(kuang);
19.
20.mapHandle(lowground , highground , coins);
21.
22.createjs.Ticker.timingMode = createjs.Ticker.RAF;//设置循环方法，可以是requestAnimationFrame或者是setTimeout
23.createjs.Ticker.setFPS(30);//舞台帧率控制
24.createjs.Ticker.addEventListener('tick', tick);//绑定舞台每一帧的逻辑发生函数
25.
26.window.addEventListener('keydown' , function(event){
27.event = event||window.event;
28.if(event.keyCode===32&&man.jumpNum<man.jumpMax){
29.man.jump();
30.}
31.})
32.}
获得加载完成后端的图片数据就直接用loader.getResult就可以获取了，跑酷游戏需要一个背景，所以，我们实例化一个sky，然后进行位图绘制，bf方法是beginBitmapFill的缩写，该方法就是开始绘制位图，后面的drawRect是位图的绘制区域，区域当然是整个画布啦，所以就是drawRect(0,0,C_W,C_H)。实例化出来sky后就直接添加到舞台stage里面就行了。接下来是实例化一个角色，createMan方法后面有说，是自己封装的。
然后进行舞台循环设置，上面有注释了，就不说了。
下面是人物模块的封装

人物模块封装就是简单的在createJs的封装之上进行进一步的封装，封装很简单，就是用createJs实例化一个精灵类，再绑定精灵表，因为本文讲createJs的大概用法，所以游戏的逻辑处理就不具体解释了。
下面贴出封装的石头以及金币模块，简单说下背景的循环，预先实例化一堆石头和金币，然后移动响应的石头，当石头移动到超出舞台区域时，把他的visible属性置为false，再重新添加一个石头在最后的位置进行新的一次移动。

封装方法跟上面的人物模块封装差不多，不过人物是用精灵类，石头金币则是用形状类了。就是通过位图的绘制，来绘制位图的图片，原理都一样。
最后是舞台逐帧处理的tick方法：
01.function tick(event){ //舞台逐帧逻辑处理函数
02.man.update();
03.
04.kuang.x = man.sprite.x+(man.picsize().w*1.5-man.size().w)/2; //参考框
05.kuang.y = man.sprite.y;
06.
07.man.ground.length=0;
08.var cg = stoneHandle();
09.
10.if(man.ground[0]&&!cg) {
11.man.ground.sort(function(a,b){return b.h-a.h});
12.man.endy = man.ground[0].y-man.picsize().h*1.5;
13.}
14.
15.allCoins.forEach(function(cc , index){
16.if(cc.shape.visible){
17.if(
18.Math.abs((kuang.x+man.size().w/2) - (cc.shape.x+cc.size().w/2)) <= (man.size().w+cc.size().w)/2&&
19.Math.abs((kuang.y+man.size().h/2) - (cc.shape.y+cc.size().h/2)) <= (man.size().h+cc.size().h)/2&&
20.!cc.isget
21.){
22.cc.isget = true;
23.countCoin.innerHTML = parseInt(countCoin.innerHTML)+1
24.}
25.cc.update();
26.}
27.})
28.
29.document.getElementById('showFPS').innerHTML = man.endy
30.stage.update(event)
31.}
在每一帧的处理，就像自己写游戏一样啦，就是把舞台里的所有对象逐个进行逻辑运算，进行相应处理。
基本上createJs的用法还是相对比较简单并且强大的。比自己去造轮子能省很多功夫。下面贴出所有代码：
