Priests and Devils

Priests and Devils is a puzzle game in which you will help the Priests and Devils to cross the river within the time limit. There are 3 priests and 3 devils at one side of the river. They all want to get to the other side of this river, but there is only one boat and this boat can only carry two persons each time. And there must be one person steering the boat from one side to the other side. In the flash game, you can click on them to move them and click the go button to move the boat to the other direction. If the priests are out numbered by the devils on either side of the river, they get killed and the game is over. You can try it in many ways. Keep all priests alive! Good luck!

1.列出游戏中提及的事物（Objects）

答：这个游戏中的事物有:

游戏角色：3个牧师、3个恶魔；

游戏场景：2个草地河岸、一艘小船；

游戏控件：开始、运动、重试按钮，时间提示；

2.请使用课件架构图编程，不接受非 MVC 结构程序

答：使用三个文件实现MVC架构设计，分别为：

Basecode.cs __ V

GenGameObjects __ M

SceneController __ C

这里写图片描述

3.在 GenGameObjects 中创建 长方形、正方形、球 及其色彩代表游戏中的对象。

答：Devil: 恶魔 Priset:牧师 Shore:河岸 Boat:船 创建效果如下图： 这里写图片描述

4.用表格列出玩家动作表（规则表），注意，动作越少越好

1

5.实验代码

在上述设计后对内容进行了修改，不再使用预设，而是代码动态生成
