打字游戏的设计与实现一．设计内容（1）功能菜单由“开始”、“速度调整”、“统计成绩”和“结束”等组成。（2）游戏开始后，出现由26个字母组成的乱序行，这时其中任一字母落下，在键盘上敲入该字母，如果输入正确，字母消失，并得分；按Esc键返回主界面；按空格键暂停；按“Enter”退出。二．设计原理本次设计用的汇编语言基本知识如下：汇编语言程序结构主体程序结构框架datasegment……dataendscodesegmentassumecs:code,ds:data,es:extrastart:movax,datamovds,ax……call****……movax,4c00hint21hcodeendsendstart子程序结构框架Nameprocfar……Nameendp宏定义结构框架Namemacro<参数>……Endm本次设计主要用到算术指令，逻辑指令，控制转移指令等如loop指令，用于循环执行某条或者某块指令集直到默认的参数(CX)为零，退出循环，执行loop循环下的下一条指令。Jmp无条件跳转指令，跳转到一个指定的标号位置。条件转移指令JZ/JNZ、JE/JNE等等，用于判断相应的标志位是否满足条件，若满足则跳转，不满足就继续往下一条指令执行。CMP比较指令，用于比较两个数的大小，设置标志位，通常和条件跳转指令关联用。CALL调用指令，用于调用子程序Int中断指令，用于中断操作总体分析程序功能分析本次设计的是打字游戏，因此，在屏幕落下字母，输入字母，并且判断输入字母和落下来的字母是否相同，如果相同，则字母消失，否则字母下落到屏幕底部消失。其具体功能如下：1.按回车键以慢速度进入游戏，ESC键退出2.按1进入速度选择界面3.若进入速度设置界面，输入1或2，表示速度为慢或快4.游戏中按esc退回主菜单5.游戏过程中按space键暂停，再次按space键继续进行游Init_gamemacroop1,op2,op3,op4,op5,op6movcx,00hmovdh,op1movdl,op2op6:movah,02hmovbh,00hint10hpushcxmovah,0ahmoval,op3movbh,00hmovcx,01hint10hpopcxinccxincop4cmpcx,op5jneop6endmclear_screenmacroop1,op2,op3,op4;清屏宏定义movah,06hmoval,00hmovbh,07hmovch,op1movcl,op2movdh,op3movdl,op4int10hmovah,02hmovbh,00hmovdh,00hmovdl,00hint10hendmmenumacroop1,op2,op3;菜单显示宏定义movah,02hmovbh,00hmovdh,op1movdl,op2int10hmovah,09hleadx,op3int21hendmdatasegmentZKdb"*********WELCOMETOPLAY**********$"nodb"date:2014/6/18$"megdb"pressEnterkeytobegin.......$"meg1db"whenaletterisdropping,pleasehitit!$"meg2db"pressspacekeytopause!$"meg3db"pressESCkeytoreturnmaininterface!$"meg4db"press'Enter'toexitwhenplayinggame!$"meg5db"GameOverContinue?y/n$"meg6db"Press1.selectspeed.2.showscore$"meg7db"selectthelevel:$"meg8db"1.easy$"meg9db"2.hard$"meg10db"yourscoreis:$"meg11db"yourhistoryscoreis:$"speeddw1800d,150d;速度lettersdb"jwmilzoeucgpravskntxhdyqfb"db"iytpkwnxlsvxrmofzhgaebudjq"db"nwimzoexrphysfqtvdcgljukda"letter_counterdb0position_flagdb78dup(0)present_positiondb1scoredb?,0dataendsstacksegmentparastack'stack'db64dup(0)stackendscodesegmentmainprocfarassumecs:code,ds:data,ss:stackstart:movax,datamovds,axmovletter_counter,00hmovpresent_position,1leasi,position_flagmovah,00hmovcx,00hinit_postion_flag:mov[si],ahincsiinccxcmpcx,78djneinit_postion_flagmovcx,00hmovah,01horch,00010000bint10hclear_screen00d,00d,24d,79dInit_game00d,00d,0ah,dl,80d,nextsign1Init_game24d,00d,0ah,dl,80d,nextsign2Init_game00d,00d,0ah,dh,25d,nextsign3Init_game00d,79d,0ah,dh,25d,nextsign4menu05d,15d,ZK;菜单信息的宏调用menu07h,15d,nomenu09d,15d,megmenu11d,15d,meg1menu13d,15d,meg2menu15d,15d,meg3menu17d,15d,meg4menu18d,15d,meg6jmpputsoundfprocnearpushaxpushdxmovdx,9fffhinal,61handal,11111100btrig:xoral,2out61h,almovcx,800hdelay:loopdelaydecdxjnetrigpopdxpopaxretsoundfendpput:movah,02h;设置光标位置movbh,00hmovdh,22dmovdl,33dint10hmovah,01h;从键盘输入任意字符int21hcmpal,'1'jzsccmpal,'2'jnzprclear_screen00d,00d,24d,79dleadx,meg11movah,09hint21hcallprint_scoremovah,01hint21hcmpal,13jzl0l0:jmpstartpr:cmpal,13jzeasysc:clear_screen01d,01d,23d,78dmenu13d,15d,meg7menu14d,15d,meg8menu15d,15d,meg9movah,1int21hcmpal,31hjeeasycmpal,32hjehardjmpsceasy:movax,speed;控制速度movspeed,axjmpbeginhard:movax,speed+2;控制速度movspeed,axjmpbeginbegin:clear_screen01d,01d,23d,78d;清屏宏调用clear_screen01d,01d,23d,78dInit_game23d,01d,01h,dl,78d,nextsign5movah,02hmovbh,00hmovdh,01hmovdl,01hint10hmovcx,00hleasi,lettersjmpnextletterppp:jmpstartnext:clear_screen01d,01d,23d,78d;是否下一轮menu13d,15d,meg5menu14d,15d,meg10callprint_scoremovah,01hint21hcmpal,79hjepppcmpdl,6ehjmpexitnextletter:movah,02h;显示字母movdl,[si]int21hincsiinccxcmpcx,78djenextcyclejmpnextletterfrom_front:subpresent_position,78djmpgobackto_sifind_zero:cmpletter_counter,78djenextcmppresent_position,78djefrom_onemovah,00hnextsi:addpresent_position,01hincsicmp[si],ahjegobackto_dicmppresent_position,78djefrom_onejmpnextsifrom_one:movpresent_position,01hjmpgobackto_sirecycle:movletter_counter,00hmovpresent_position,01dleasi,position_flagmovcx,00hmovah,00hclearsi:mov[si],ahinccxcmpcx,78djenextcycleincsijmpclearsinextcycle:leadi,lettersleasi,position_flagaddpresent_position,31dcmppresent_position,78jafrom_frontgobackto_si:addsi,wordptrpresent_positiondecsimovah,[si]cmpah,01hjefind_zerogobackto_di:movah,01hmov[si],ahadddi,wordptrpresent_positiondecdimovdl,present_positionmovah,02hmovbh,00hmovdh,01hint10hmovcx,00hnextrow:pushcxmovcx,00hjmpout_cycleout_cycle:;延迟pushcxmovcx,00hjmpin_cycleggg:incscoremoval,score+1movscore,aljmpdisappearin_cycle:addcx,01hcmpcx,40000jnein_cyclepushdxmovah,06h;从键盘输入字符movdl,0ffhint21hpopdxjzpasscmpal,1bh;如果键入ESC，则返回主菜单jeto_start1cmpal,"";如果键入SPACE，则游戏暂停jepausecmpal,13jnzignorejmpexitignore:cmpal,[di];输入字母正确！则字母消失!!!!!!!jegggpass:popcxinccxcmpcx,speedjeprintjmpout_cyclepause:pushdx;暂停处理movah,06hmovdl,0ffhint21hpopdxcmpal,""jnepausejmppassto_start1:;返回主菜单jmpstartprint:movah,0ah;在当前光标位置写空格moval,""movbh,00hmovcx,01hint10hincdhmovah,02h;改变光标位置movbh,00hint10hmovah,0ah;在当前光标位置写字母moval,[di]movbh,00hmovcx,01hint10hpopcxinccxcmpcx,21djeprint_next_letterjmpnextrow;下一行disappear:;击中字母后输出空格movah,0ahmoval,""movbh,00hmovcx,01hint10hcallsoundfjmphitprint_next_letter:movah,0ahmoval,""movbh,00hmovcx,01hint10hi
