俄罗斯方块程序.docx

1、俄罗斯方块程序大概在最近两天之内编码完成，但此前一天开始构思。第一天晚上主要完成了方块旋转算法，第二天也就是今天加了消方块的处理算法。但是可能还有一些考虑不周的地方，比如，没有采用定时中断，而是图方便采用了和cpu频率有关的delay（）函数来模拟时间间隔，这是需要改进的地方。其中的主要逻辑有：（1）由于c的随机性函数不好，所以每次游戏开始根据bios时间设置种子。（2）得分越高，方块下降速度越快（每200分为单位）。（3）每下落一个方块加1分，每消除一行加10分，两行加30分，三行加70分，四行加150分。初试分数为100分。游戏控制： up-旋转；空格-下落到底； 左右下方向键-控制方向。

2、P-开始或暂停游戏。 ESC-退出。特点：（1）由于tc不支持中文，所以基本都是英文注释。（2）函数命名尽可能规范的表达其内部处理目的和过程。（3）代码加上注释仅有577行。（我下载过的两个俄罗斯方块代码一个在1087行，一个在993行，我的比它们代码少）。（4）除了消除空格时算法比较复杂，其他算法都比较简单易读。（5）绘图效率和局部代码效率扔有待提高。（6）FrameTime参数可能依据不同硬件环境进行具体设置，InitGame需要正确的TC路径。 俄罗斯方块源于大约9年前上大一时的一个梦，我们在学习c语言时，我的同寝室友邀请我合作一起完成俄罗斯方块（课外作业性质），但是当时限于我们的水平比

3、较菜和学习状态比较懒散，我们没有完成。大一的时候我在机房里无意发现别人留下的俄罗斯方块程序，运行，老师发现后激动的问我是我写的吗，我惭愧的摇摇头。那时看到别人做c的大程序深感羡慕（自己只是写几十行的程序）。数年后我仍然看到有不同样式的实现，但是我一直没有实现它，知道今天忽然有这个想法去做，算是弥补多年前的遗憾和心愿吧。-【以下是我的代码文件：】-/*/* Desc:俄罗斯方块游戏*/* By:hoodlum1980*/* Email:jinfd*/* Date:2008.03.12 22：30*/*/#include #include #include #include #include #i
