Ich möchte auf HTML5-Spiele umsteigen. Es wurde zuerst prozessorientiert und dann objektorientiert implementiert...

游戏规则：<br/>
1、一个玩家、两个色子，每个色子有1-6个点，点数随机出现，点数是2-12中的任意数字<br/>
2、如果玩家第一次抛出 7 或者 11，则本回合胜利 进行下一回合<br/>
3、如果玩家抛出2、3、12 则回合失败 进行下一回合<br/>
4、抛出其他数字4、5、6、7、8、9、10 记录点数和，并继续掷色子<br/>
5、当玩家掷出7 则本回合失败 进行下一回合<br/>
6、当玩家抛出的点数和与上一次的相同，本局胜利 进行下一回合<br/>
7、当玩家抛出的点数和与上一次的不同，本局失败，进行下一回合<br/>
后期扩展：<br/>
这个游戏有押注和积分的功能，尚无思路，所以没有实现<br/>

game:{游戏对象
}
Stage={场景对象
add(thing) //添加一个物件
addEvent(type,handler)
redraw() //重绘所有thing对象
}
Thing = {//物件对象
draw(canvas)//传入一个canvas画板对象用于绘制thing
isScope(x,y) //传入鼠标相对于canvas的位置，返回boolean，
//用于判断鼠标是否在thing的范围 true在，false不在
addEvent(type,handler) //公开方法 //给物件设置时间
}
定义我们自己的场景对象
掷色子的场景内需要：
1、两个色子 色子一号 色子二号
2、一个公告板 显示本局信息
3、三个按钮 重现开始
