原生js结合html5制作简易的双色子游戏

人气:1

想转html5游戏开,这是学习练手的东西,最开始是用面向过程的方式实现,后面用面向对象的方式实现(被坑了)……

          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/>

          这个游戏有押注和积分的功能,尚无思路,所以没有实现<br/>

        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
