Html5游戏框架createJs的简单用法

声明:本文为原创文章,如需转载,请注明来源WAxes,谢谢!http://www.it165.net/pro/html/201403/11105.html

  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。

001.(function(w){
002.var SPEED = 4,
003.COIN_STAY_X = 20,
004.COIN_STAY_Y = 20,
005.COIN_STAY_WIDTH = 30,
006.COIN_STAY_HEIGHT = 30,
007.COIN_SCALE_X = 0.08,
008.COIN_SCALE_Y = 0.08;
009. 
010.//地上的石头类
011. 
012.var Stone = function(x,kind,allImage){
013.this.x = x;
014.this.kind = kind;
015.this.allImage = allImage;
016.this.init();
017.}
018. 
019.var sp = Stone.prototype;
020. 
021.sp.init=function(){
022.this.shape = new createjs.Shape();
023.if(this.kind!=='C'){
024.this.h = this.allImage[this.kind].height;
025.this.w = this.allImage[this.kind].width*2;
026.this.y = C_H - this.h;
027.this.shape.graphics.beginBitmapFill(this.allImage[this.kind]).drawRect(0, 0, this.w, this.h);
028.this.shape.setTransform(this.x, this.y, 1, 1);
029.}else {
030.this.h = -1000;
031.this.w = 170;
032.this.y = C_H - this.h;
033.this.shape.graphics.beginFill('#000').drawRect(0, 0, this.w, this.h);
034.this.shape.setTransform(this.x, this.y, 1, 1);
035.}
036.this.shape.visible = false;
037.this.shape.cache(0 , 0 , this.w , this.h);
038.stage.addChild(this.shape);
039.}
040. 
041.sp.update=function(){
042.this.shape.x -= SPEED;
043.}
044. 
045.//金币类
046.var Coin = function(image){
047.this.sizeX = COIN_SCALE_X;
048.this.sizeY = COIN_SCALE_Y;
049. 
050.this.isget = false;
051.this.init = function(){
052.this.shape = new createjs.Shape();
053.this.shape.graphics.beginBitmapFill(image).drawRect(0, 0, image.width, image.height);
054.this.shape.setTransform(0, 0, COIN_SCALE_X, COIN_SCALE_Y);
055.this.shape.visible = false;
056.stage.addChild(this.shape);
057.}
058.this.init();
059. 
060.this.update = function(){
061.if(this.isget){
062.this.sizeX = this.sizeX + ((COIN_STAY_WIDTH/image.width) - this.sizeX)*0.1;
063.this.sizeY = this.sizeY + ((COIN_STAY_HEIGHT/image.height) - this.sizeY)*0.1;
064.this.shape.setTransform(
065.this.shape.x + (COIN_STAY_X - this.shape.x)*0.1,
066.this.shape.y + (COIN_STAY_Y - this.shape.y)*0.1,
067.this.sizeX,
068.this.sizeY
069.);
070. 
071.if(Math.abs(this.shape.x-COIN_STAY_X)<0.5&&Math.abs(this.shape.y-COIN_STAY_Y)<0.5){
072.this.shape.visible = false;
073.this.isget = false;
074.this.sizeX = COIN_SCALE_X;
075.this.sizeY = COIN_SCALE_Y;
076.this.shape.setTransform(0,0,this.sizeX,this.sizeY);
077.}
078.} else{
079.this.shape.x -= SPEED;
080.if(this.shape.x<-image.width*COIN_SCALE_X){
081.this.shape.visible = false;
082.}
083.}
084.}
085. 
086.this.size = function(){
087.return {
088.w:image.width*COIN_SCALE_X,
089.h:image.height*COIN_SCALE_Y
090.}
091.}
092.}
093. 
094.w.createCoin = function(image){
095.return new Coin(image)
096.}
097. 
098.w.createStone = function(x,kind,allImage){
099.return new Stone(x,kind,allImage);
100.}
101.})(window)

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:

简单的记录,如果有疑问请在评论提出,楼主看到会尽量解答。。。。自己用createJs的时候,最好多查查API文档哈,createJs的文档还是挺全面的,如果看不懂英文,就跟楼主一样下载个有道词典吧。哈哈哈。
