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：

function init(){
stage = new createjs.Stage('cas');
C_W = stage.canvas.width;
C_H = stage.canvas.height;
 
var manifest = [
{src:'image/man.png' , id:'man'},
{src:'image/ground.png' , id:'ground'},
{src:'image/bg.png' , id:'bg'},
{src:'image/high.jpg' , id:'high'},
{src:'image/coins.png' , id:'coin'}
]
 
loader = new createjs.LoadQueue(false);
loader.addEventListener('complete' , handleComplete);
loader.loadManifest(manifest);
 
drawLoading();
}

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：

function handleComplete(){        //当图片素材load完后执行该方法
var manImage = loader.getResult('man'),
lowground = loader.getResult('ground'),
highground = loader.getResult('high'),
bgImage = loader.getResult('bg'),
coins = loader.getResult('coin');
 
sky = new createjs.Shape();
sky.graphics.bf(bgImage).drawRect(0,0,C_W,C_H);
sky.setTransform(0, 0, 1 , C_H/bgImage.height);
stage.addChild(sky);
 
man = createMan(200,326,manImage);
 
//该框为判定角色的判定区域
kuang = new createjs.Shape();
kuang.graphics.beginStroke('rgba(255,0,0,0.5)').drawRect(0 , 0 , man.size().w , man.picsize().h*1.5);
// stage.addChild(kuang);
 
mapHandle(lowground , highground , coins);
 
createjs.Ticker.timingMode = createjs.Ticker.RAF;//设置循环方法，可以是requestAnimationFrame或者是setTimeout
createjs.Ticker.setFPS(30);//舞台帧率控制
createjs.Ticker.addEventListener('tick', tick);//绑定舞台每一帧的逻辑发生函数
 
window.addEventListener('keydown' , function(event){
event = event||window.event;
if(event.keyCode===32&&man.jumpNum<man.jumpMax){
man.jump();
}
})
}

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

this.init(img);
}
 
Man.prototype = {
constructors:Man,
 
init:function(img){
var manSpriteSheet = new createjs.SpriteSheet({　　//实例化精灵表绘制器
'images':[img],

}

var nexty = sprite.y+time*this.vy*PROPORTION;

if(Math.abs(sprite.y-this.endy)<10&&this.vy>0){

sprite.y=this.endy;
this.vy = 0;
}
}
 
if(sprite.x+(PICWIDTH*SCALE_X-WIDTH)/2<0||sprite.y>C_H+200){
this.die();
createjs.Ticker.reset();
alert('you are Die!');
}
 
switch(this.state){
case 'run':
this.jumpNum = 0;
break;
case 'die':
if(sprite.currentFrame===0){

}
break;
}
},
 
run:function(){
this.sprite.gotoAndPlay('run')
},
 
jump:function(){
this.vy = -JUMP_SPEED;
this.state = 'jump';
this.sprite.gotoAndPlay('jump');　　//让精灵表播放特定的动画
this.jumpNum++;
},
 
die:function(){
this.state = 'die';
this.sprite.gotoAndPlay('die')
},
 
size:function(){
return {
w:WIDTH,

},
 
picsize:function(){
return {

}
}
}

return new Man(x , y , img)
};
})(window)

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。

(function(w){
var SPEED = 4,
COIN_STAY_X = 20,
COIN_STAY_Y = 20,
COIN_STAY_WIDTH = 30,
COIN_STAY_HEIGHT = 30,
COIN_SCALE_X = 0.08,
COIN_SCALE_Y = 0.08;
 
//地上的石头类
 
var Stone = function(x,kind,allImage){
this.x = x;
this.kind = kind;
this.allImage = allImage;
this.init();
}
 
var sp = Stone.prototype;
 
sp.init=function(){
this.shape = new createjs.Shape();
if(this.kind!=='C'){
this.h = this.allImage[this.kind].height;
this.w = this.allImage[this.kind].width*2;
this.y = C_H - this.h;
this.shape.graphics.beginBitmapFill(this.allImage[this.kind]).drawRect(0, 0, this.w, this.h);
this.shape.setTransform(this.x, this.y, 1, 1);
}else {
this.h = -1000;
this.w = 170;
this.y = C_H - this.h;
this.shape.graphics.beginFill('#000').drawRect(0, 0, this.w, this.h);
this.shape.setTransform(this.x, this.y, 1, 1);
}
this.shape.visible = false;
this.shape.cache(0 , 0 , this.w , this.h);
stage.addChild(this.shape);
}
 
sp.update=function(){
this.shape.x -= SPEED;
}
 
//金币类
var Coin = function(image){
this.sizeX = COIN_SCALE_X;
this.sizeY = COIN_SCALE_Y;
 
this.isget = false;
this.init = function(){
this.shape = new createjs.Shape();
this.shape.graphics.beginBitmapFill(image).drawRect(0, 0, image.width, image.height);
this.shape.setTransform(0, 0, COIN_SCALE_X, COIN_SCALE_Y);
this.shape.visible = false;
stage.addChild(this.shape);
}
this.init();
 
this.update = function(){
if(this.isget){
this.sizeX = this.sizeX + ((COIN_STAY_WIDTH/image.width) - this.sizeX)*0.1;
this.sizeY = this.sizeY + ((COIN_STAY_HEIGHT/image.height) - this.sizeY)*0.1;
this.shape.setTransform(
this.shape.x + (COIN_STAY_X - this.shape.x)*0.1,
this.shape.y + (COIN_STAY_Y - this.shape.y)*0.1,
this.sizeX,
this.sizeY
);
 
if(Math.abs(this.shape.x-COIN_STAY_X)<0.5&&Math.abs(this.shape.y-COIN_STAY_Y)<0.5){
this.shape.visible = false;
this.isget = false;
this.sizeX = COIN_SCALE_X;
this.sizeY = COIN_SCALE_Y;
this.shape.setTransform(0,0,this.sizeX,this.sizeY);
}
} else{
this.shape.x -= SPEED;
if(this.shape.x<-image.width*COIN_SCALE_X){
this.shape.visible = false;
}
}
}
 
this.size = function(){
return {
w:image.width*COIN_SCALE_X,
h:image.height*COIN_SCALE_Y
}
}
}
 
w.createCoin = function(image){
return new Coin(image)
}
 
w.createStone = function(x,kind,allImage){
return new Stone(x,kind,allImage);
}
})(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：

function tick(event){        //舞台逐帧逻辑处理函数
man.update();
 
kuang.x = man.sprite.x+(man.picsize().w*1.5-man.size().w)/2;    //参考框
kuang.y = man.sprite.y;
 
man.ground.length=0;
var cg = stoneHandle();
 
if(man.ground[0]&&!cg) {
man.ground.sort(function(a,b){return b.h-a.h});
man.endy = man.ground[0].y-man.picsize().h*1.5;
}
 
allCoins.forEach(function(cc , index){
if(cc.shape.visible){
if( 
Math.abs((kuang.x+man.size().w/2) - (cc.shape.x+cc.size().w/2)) <= (man.size().w+cc.size().w)/2&&
Math.abs((kuang.y+man.size().h/2) - (cc.shape.y+cc.size().h/2)) <= (man.size().h+cc.size().h)/2&&
!cc.isget
){
cc.isget = true;
countCoin.innerHTML = parseInt(countCoin.innerHTML)+1
}
cc.update();
}
})
 
document.getElementById('showFPS').innerHTML = man.endy
stage.update(event)
}

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。
