html游戏引擎，createJs框架

声明：本文为原创文章，如需转载，请注明来源WAxes，谢谢！

　　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。

　　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。

　　接下来开始分析代码：

view source print ?

1.<script src=‘easeljs-0.7.1.min.js‘></script>

2.<script src=‘preloadjs-0.4.1.min.js‘></script>

view source print ?

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.}

view source print ?

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.}

　　然后进行舞台循环设置，上面有注释了，就不说了。

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。

最后是舞台逐帧处理的tick方法：

view source print ?

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。
