C语言写的俄罗斯方块程序减小字体 增大字体 作者：佚名 来源：不详 发布时间：2009-9-21 1:11:22收藏到网摘： 合作洽谈 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。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: */* Date: 2008.03.12 22：30 */*/#include #include #include #include #include #include #define true 1#define false 0#define BoardWidth 12#define BoardHeight 23#define _INNER_HELPER /*inner helper method */*Scan Codes Define*/enum KEYCODES K_ESC =0x011b, K_UP =0x4800, /* upward arrow */ K_LEFT =0x4b00, K_DOWN =0x5000, K_RIGHT =0x4d00, K_SPACE =0x3920, K_P =0x1970;/* the data structure of the block */typedef struct tagBlock char c44; /* cell fill info array, 0-empty, 1-filled */ int x; /* block position cx 0,BoardWidht -1 */ int y; /* block position cy -4,BoardHeight-1 */ char color; /* block color */ char size; /* block max size in width or height */ char name; /* block name (the blocks shape) */ Block;/* games global info */int FrameTime= 1300;int CellSize= 18;int BoardLeft= 30;int BoardTop= 30;/* next block grid */int NBBoardLeft= 300;int NBBoardTop= 30;int NBCellSize= 10;/* score board position */int ScoreBoardLeft= 300;int ScoreBoardTop=100;int ScoreBoardWidth=200;int ScoreBoardHeight=35;int ScoreColor=LIGHTCYAN;/* infor text postion */int InfoLeft=300;int InfoTop=200;int InfoColor=YELLOW;int BorderColor=DARKGRAY;int BkGndColor=BLACK;int GameRunning=true;int TopLine=BoardHeight-1; /* top empty line */int TotalScore=100;char info_score20;char info_help255;char info_common255;/* our board, Boardxy0-isFilled, Boardxy1-fillColor */unsigned char BoardBoardWidthBoardHeight2;char BufferCells44; /* used to judge if can rotate block */Block curBlock; /* current moving block */Block nextBlock; /* next Block to appear */* function list */int GetKeyCode();int CanMove(int dx,int dy);int CanRotate();int RotateBlock(Block *block);int MoveBlock(Block *block,int dx,int dy);void DrawBlock(Block *block,int,int,int);void EraseBlock(Block *block,int,int,int);void DisplayScore();void DisplayInfo(char* text);void GenerateBlock(Block *block);void NextBlock();void InitGame();int PauseGame();void QuitGame();/*Get Key Code */int GetKeyCode() int key=0; if(bioskey(1) key=bioskey(0); return key;/* display text!
