黄金点游戏
基本要求:
N个同学(N通常大于10),每人写一个0~100之间的有理数 (不包括0或100),交给裁判,裁判算出所有数字的平均值,然后乘以0.618(所谓黄金分割常数),得到G值。提交的数字最靠近G(取绝对值)的同学得到N分,离G最远的同学得到-2分,其他同学得0分。
主要功能:
每位玩家输入名字和数字(必须大于两位玩家),最后一位玩家点击结束游戏,由程序计算出G值,并判断每位玩家的得分情况。
设计思想:
我们组是在android平台上开发的这个游戏,因为android提供了更好的图形界面,能使游戏变得更加有趣。
小组成员:
我和室友陈亮一起完成了此次编程练习,我负责代码查找与修改,他负责测试以及优化。
我们的代码来自https://coding.net/u/rayshea/p/android-based-golden-point/git,经过我们自己修改优化,增加了保存数据,删除数据等方法,将这个小游戏做得更加完善。代码地址:https://github.com/xiaofancheng/goldenPoint。
下面是我们项目的主要代码以及效果图:
