PAGEPAGE2汇编语言课程设计设计题目:指法练习班级:计算机04-4班学号:20042390作者:王丰指导老师:郑利平日期:2007.1.5汇编语言课程设计报告<打字游戏>课程设计目的课程设计使学生更进一步理解和掌握汇编语言知识、程序设计的方法和技巧，使学生能够使用汇编语言分析、设计中小型程序的能力。通过课程设计，有助于学生更好的了解整个课程的知识体系，锻炼学生运用本课程的知识解决更复杂的实际问题的能力，从而为后续课程的学习、毕业设计以及将来的实际工作打好坚实的基础。二、设计题目指法练习设计要求1、从屏幕上方以一定的时间间隔随机落下可显示字符，字符的出现位置亦是随机的；2、在多个字符下落的过程中可输入任意键，若键入与其中的任意一个字符相匹配的键，则该字符高亮显示并发出蜂鸣声，同时计分；3、按ESC键结束练习并显示命中率；4、再次按ESC键退出。四、设计环境硬件:PC机,软件:masm5.0设计分析指法练习,是在屏幕上以一定的时间间隔随机的下落一写字符,我在程序中的设计方法是从屏幕的第一行开始显示一个字符,然后在用一个时间延时函数延时一段时间,再在此位置显示空格字符,延时后在同一列的下一行显示原字符,如此循环,中间如果有输入正确的字符,则,循环停止,并同时将此字符高亮显示,方法是改变此字符的属性,并将score加1,然后光标移到第一行还是新的循环.若输入中间字符不正确,循环到21行时,则扬声器发出蜂鸣声,同时life减1.设计中要求每次下落的字符是随机的,我在程序中的设计方法是取系统时间1/100秒,然后将此时间模取26,将得到余数加上61,将此作为输出字符的ASCLL码,如此循环78次,将这些字符存入letter缓冲区,并在屏幕最上方显示出来.开始下落的字母的位置也是随机的,同样取系统时间,,由于一行最多只能有78个字符,所以当取的时间大于等于78时,应减去78,将得到的结果作为取字符的位置,此种随机虽然不是很严谨,但用在此程序中还是很不错的.题目中还要求计算命中率,由于在游戏开始的同时开始了记分,所以在结束游戏时,将得分和错误统计出来,很容易计算出命中率,这里就不做多余的叙述.在题目的要求的基础上,我还给游戏增加了几个难度,其实也很简单,就是控制字母下落的速度,方法是改变每次字符显示的时间间隔,这样从屏幕上看,字母下落就会有快慢.程序的模块程序设计时,我没有分模块,只有实现个别功能的几个子程序,分别是发声程序,延时程序,和命中率计算与显示程序,这在原代码中均有注释,在此就不在详细叙述.课程设计心得由于课程设计开始的比较早,所以有时间去准备.开始时在网上看了一些资料和例子,搞清楚了程序设计的基本原理.最开始不明白的地方就是如何让字符下落,后来发现就是不停的在屏幕的不同位置显示该字符,加以延时,看起来就像是字符不断的从上面掉下来.随机问题也是本程序的一个难点,看过资料后知道汇编中没有现成的完美的随机函数.所以我就想到取系统时间来制造随机数,因为时间时刻都在变化,而且打字的时间也不一定,结果游戏的随机性还不错,呵呵这学期汇编的学习,自己感觉还不错,平时也练习了不少.从汇编程序的学习中,我觉得自己突然一下子明白了一般程序设计的原理,看程序时,不再感觉茫然,自己写点小程序时,也知道该如何下手.算法上也学到了不少新的东西,总算劳有所获吧!本打算把程序的运行流程图画出来,无奈,最近考试太多,时间实在不够啊,只有在程序中直接注释了,其实程序的思路很清晰,相信大家多能看懂最后,感谢郑利平老师一学期来指导和帮助,也感谢我们班的桑磊同学在课程设计中给我解答疑问!八、源程序如下:;=======================================================================;打字游戏程序;=======================================================================init_gamemacroop1,op2,op3,op4,op5,op6;循环输出,用于初始化界面movcx,0movdh,op1;起行movdl,op2;起列op6:movah,02hmovbh,00hint10hpushcxmovah,0ahmoval,op3;要显示的字符movcx,01hmovbh,00hint10hpopcxinccxincop4;指出循环输出的是行还是列cmpcx,op5;循环次数jneop6endm;=======================================================cleanmacroop1,op2,op3,op4;用于清屏,分别是起止的行和列movah,6movbh,00010111bmoval,0movch,op1movcl,op2movdh,op3movdl,op4int10hmovah,2movbh,0movdh,0movdl,0int10hendm;======================================================menumacroop1,op2,op3;用于屏幕上文字的输出movcx,0movah,02hmovbh,00hmovdh,op1movdl,op2int10hleadx,op3movah,9int21hendm;=======================================================datasegmentfgfdb'===============================================$';分隔符menu1db'1.startgame$'menu2db'2.selectlevel$';主界面上显示的内容menu3db'3.exit$'menu4db'selectnumberofmenu:$'menu5db'author:wangfeng$'menu6db'NO.:20042390$'menu7db'1.veryeasy$'menu8db'2.normal$';难度的选择menu9db'3.hard$'menu10db'4.return$'menu11db'data:2006.12.24$'meg1db'pressanykeytostartthegame...$';游戏开始之前的提示meg2db'pressesckeyreturnmainmenu$'meg3db'pressspacekeyforpause$'meg4db'whenthegamewaspaused,pressesetoquit!$'meg5db'life:$';生命数meg6db'score:$';分数meg7db'hittheletternum:$'meg8db'missletternum:$'meg9db'theshootingis:$'madb0mbdb0sped1dw0speeddw3000d;游戏的速度,也决定了游戏的难度lettersdb78dup(0);上方显示的字母lifedb39hpositiondb1;上方字母的位置用于控制落下的字母time_mdb0time_sdb0xmuldb13ndb26score1db0leveldb1hangdb0linedb0fen1db0fen2db0fen3db0fen4db0fen5db0stringdb'100%$'errordb0dataends;============================================codesegmentassumecs:code,ds:data;,ss:stackstart:movax,datamovds,ax;这里是几个数据的初始化movposition,1movspeed,3000movlevel,1movsped1,50000moverror,0movscore1,0jiemian:movah,01hmovcx,00horch,00010000bint10h;置光标类型,用于隐藏光标clean0,0,24,79;下面这些是游戏的初始化init_game0,0,08h,dl,80,sk1init_game24,0,08h,dl,80,sk2init_game0,0,08h,dh,25,sk3init_game0,79,08h,dh,25,sk4menu5,15,fgfmenu7,25,menu1;界面显示menu9,25,menu2menu11,25,menu3menu13,15,fgfmenu15,25,menu4menu17,55,menu5menu19,55,menu6menu21,55,menu11movah,2movbh,0movdh,15movdl,47int10h;把光标放在合适的位置movah,0ahmoval,''movbh,00hmovcx,01hint10h;在选择时屏蔽其他的按键,使之不出现在屏幕上movah,1int21hinput:cmpal,'1'jebegin;当输入字符是1时,;跳转到begin开始游戏cmpal,'2'jeto_speed_c;当输入字符是2时,跳转,;由于不能直接跳转到;speed_c故用了个转移cmpal,'3'jeto_exitcmpal,1bhjeto_exit_dto_otherkey:jmpotherkeyto_exit:movah,1int21hcmpal,0dhjneto_otherkeyjmpexitto_speed_c:jmpspeed_cto_exit_d:jmpexit;===================================begin:movah,1int21hcmpal,0dhjneto_otherkeyclean1,1,23,78play_message:;显示有关游戏提示menu10,18,meg1menu12,18,meg2menu14,18,meg3menu16,18,meg4movah,07hint21hcmpal,1bh;按任意键继续,;不把输入的字符显示在屏幕上jeto_jmjmpplayto_jm:jmpjiemianplay:clean1,1,23,78movlife,39hmovah,2movbh,0movdh,1movdl,1int10hmovbx,0leasi,lettersoutput_letters:;显示上方字母movah,2chint21hmoval,dlmovah,0divnmovdl,ahadddl,61hmov[si],dlmovah,2int21hmovcx,14987callwaitfincsiincbxcmpbx,78jenextjmpoutput_lettersnext:menu23,70,meg5menu23,30,meg6;生命数的相关显示pushdxmovah,2movbh,0movdh,23movdl,76int10hmovah,0ahmoval,lifemovbh,0movcx,1int10hmovah,2movbh,0movdh,23movdl,43int10hmovah,0ahmoval,score1moval,30hmovbh,0movcx,1int10hpopdxjmpgamesub_p:subposition,78cmpposition,0jnenext3incpositionnext3:jmpgame_nextgame:leasi,lettersmovah,2ch;伪随机算法,方法是读取1/100秒,int21hmoval,dlmovposition,alcmpposition,0jnenext2incpositionnext2:cmpposition,78;和78比较,大于则减去78jasub_pgame_next:addsi,wordptrpositiondecsimovdl,position;position就代表
