原生js結合html5制作簡易的雙色子游戲
編輯：關於JavaScript
想轉html5游戲開，這是學習練手的東西，最開始是用面向過程的方式實現，後面用面向對象的方式實現(被坑了)……

游戲規則：<br/>
1、一個玩家、兩個色子，每個色子有1-6個點，點數隨機出現，點數是2-12中的任意數字<br/>
2、如果玩家第一次拋出 7 或者 11，則本回合勝利 進行下一回合<br/>
3、如果玩家拋出2、3、12 則回合失敗 進行下一回合<br/>
4、拋出其他數字4、5、6、7、8、9、10 記錄點數和，並繼續擲色子<br/>
5、當玩家擲出7 則本回合失敗 進行下一回合<br/>
6、當玩家拋出的點數和與上一次的相同，本局勝利 進行下一回合<br/>
7、當玩家拋出的點數和與上一次的不同，本局失敗，進行下一回合<br/>
後期擴展：<br/>
這個游戲有押注和積分的功能，尚無思路，所以沒有實現<br/>

游戲規則：
一個玩家、兩個色子，每個色子有1-6個點，點數隨機出現，點數是2-12中的任意數字
如果玩家第一次拋出 7 或者 11，則本回合勝利 進行下一回合
如果玩家拋出2、3、12 則回合失敗 進行下一回合
拋出其他數字4、5、6、7、8、9、10 記錄點數和，並繼續擲色子
當玩家擲出7 則本回合失敗 進行下一回合
當玩家拋出的點數和與上一次的相同，本局勝利 進行下一回合
當玩家拋出的點數和與上一次的不同，本局失敗，進行下一回合
game:{游戲對象
}
Stage={場景對象
add(thing) //添加一個物件
addEvent(type,handler)
redraw() //重繪所有thing對象
}
Thing = {//物件對象
draw(canvas)//傳入一個canvas畫板對象用於繪制thing
isScope(x,y) //傳入鼠標相對於canvas的位置，返回boolean，
//用於判斷鼠標是否在thing的范圍 true在，false不在
addEvent(type,handler) //公開方法 //給物件設置時間
}
定義我們自己的場景對象
擲色子的場景內需要：
1、兩個色子 色子一號 色子二號
2、一個公告板 顯示本局信息
3、三個按鈕 重現開始
