[留念贴] C#开发技术期末大作业——星月之痕

明天就要去上海大学参加 2015赛季 ACM/ICPC 最后一场比赛 —— EC-Final，在这之前，顺利地把期末大作业赶出来了。

纯手工打造。庆幸的是，历时四天，现在基本完工了。

做个作业真不容易，音乐要自己找，图片要自己P，代码也要自己写... ... 早起晚睡，脖子酸... ...

下载之后先解压，然后打开DestroyStars\DestroyStars\bin\Debug文件夹下的DestroyStars.exe

据说会报毒！？ 我那么善良的人怎么会制造病毒... .. 如果报毒了，解压之前关闭一下杀毒软件吧...真的没毒的。。。

【开发过程】

Day 1.上午  “妈呀..期末快到了耶！C#学了什么？好像什么都不会啊！”.....就这样，我开始了我的期末大作业的开发，上午看了一下老师的课件，随便琢磨了一下就开始了，游戏中的所有星星方块都是一张一张的图片，画图部分就纠结了半天了，但最后还是被我画了出来。

Day 1.下午 先做了随机生成10*10地图，这个似乎so easy.. .. 然后我就是到了算法部分了，也是整个游戏中仅有的我最擅长写的一部分，消灭星星消除的是连通块，本想用广度优先搜索的，但是因为不知道C#中队列的语法，最终还是采用了深度优先搜索。palapala，这部分很快就写完了。之后做的就是方块移动的过程，也不难吧，用timer控制一下，每隔一定的时间刷新一下图片的位置。 第一天结束之后，把最最核心的东西完成了，之后就是外观与游戏玩法的添加。

Day2. 这一天似乎做的事情比较少，找了几张星星、鼠标的图片，然后消除效果的制作。

Day3. 三个技能基本定型，RMB系统基本定型，积分系统基本定型，外观基本定型。

Day4. 闯关模式基本定型，加上了音效与背景音乐，写了一下玩法说明书。

 

代码不多贴了，下载之后也能看到的。

放一下 Game.CS 的吧.
