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:
1.
<script src=
'easeljs-0.7.1.min.js'
></script>
2.
<script src=
'preloadjs-0.4.1.min.js'
></script>
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.
}
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。

15.

17.
if

19.

2

2

20.

21.

22.

true
;
23.
countCoin.innerHTML = parseInt(countCoin.innerHTML)+
1
24.
}
25.
cc.update();
26.
}
27.
})
28.
29.
document.getElementById(

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。
