Question

好吧，如果您将此代码放在批处理文件中：

它不会选择一个随机数（或者它是否总是有相同的结果）
如果你选择战斗，它似乎失败或胜利
我一直在教自己编码，这是我第一次参加论坛，所以请放轻松我：）

这是我的代码：

@echo off
title template
color 0F
pause

:menu
cls
echo 1.start
echo 2.instructions
echo 3.exit
set /p answer=Type the number of your option and press enter
if %answer%==1 goto start_1
if %answer%==2 goto instructions
if %answer%==3 goto exit

:exit
echo thanks for playing
pause
exit /b

:instructions
cls
echo instructions
echo.
echo This game is case-sensitive!
echo Just have fun with it!
pause
goto menu

:start_1
set /a s1=%random% * 3 / 32768 + 1
if %s1%==1 goto prefight_1
if %s1%==2 goto prefight_2
if %s1%==3 goto prefight_3

:prefight_1
cls
echo You have discovered 3 Turtles!
echo They dont see you!
set /p answer=would you like to (1)FIGHT or (2)RUN?
if %answer%==1 goto fight_1
if %answer%==2 goto run_1

:fight_1
set /a f1=%random% * 4 / 32768 + 1
if %f1%==1 goto lose_fight_1
if %f1%==2 goto win_fight_1
if %f1%==3 goto win_fight_1
if %f1%==4 goto win_fight_1

:prefight_2
cls
echo You have discovered 3 Turtles!
echo They see you!
set /p answer=would you like to (1)FIGHT or (2)RUN?
if %answer%==1 goto fight_2
if %answer%==2 goto run_1

:fight_2
set /a f2=%random% * 4 / 32768 + 1
if %f2% gtr 4 goto fight_2
if %f2% lss 1 goto fight_2
if %f2%==1 goto lose_fight_1
if %f2%==2 goto lose_fight_1
if %f2%==3 goto win_fight_1
if %f2%==4 goto win_fight_1

:prefight_3
cls
echo You have discovered 3 Turtles!
echo They see you!
echo They seem angry!
set /p answer=would you like to (1)FIGHT or (2)RUN?
if %answer%==1 goto fight_3
if %answer%==2 goto run_1

:fight_3
set /a f3=%random% * 4 / 32768 + 1
if %f3%==1 goto lose_fight_1
if %f3%==2 goto lose_fight_1
if %f3%==3 goto lose_fight_1
if %f3%==4 goto win_fight_1

:lose_fight_1
cls
echo Sorry,You LOST!
echo Thank you for playing!
echo made by: JEREMY
set /p answer==(1)continue or (2)quit?
if %answer%==1 goto start_1
if %answer%==2 goto menu
pause

:run_1
cls
echo You ran away
pause
goto start_1

Answer 1

首先，人类在“等于”而非“==”时阅读会更好。设置/ p VARIABLE =在清除时更容易使用，所以像这样使用echo：

:Jelly_Attack_1
cls
echo AH! There's a swarm of angry jellyfish!
echo Act fast!
echo.
echo You can (1) fight or (2) RUN
set /p VARIABLE=
if %VARIABLE% equ 1 goto Fight_Jelly_1
if %VARIABLE% equ 2 goto Run
if %VARIABLE% neq 1 goto TEST

战斗部分看起来应该是这样的：

:Fight_Jelly_1
cls
echo The jellyfish are more annoying than harmful!
echo You have a great advantage!
pause
set /a FIGHTNO=%random%
if %FIGHTNO% gtr 4 goto Fight_Jelly_1
if %FIGHTNO% lss 1 goto Fight_Jelly_1
if %FIGHTNO% equ 1 goto FAILED
if %FIGHTNO% equ 2 goto Fight_Jelly_1_Win
if %FIGHTNO% equ 3 goto Fight_Jelly_1_Win
if %FightNO% geq 4 goto Fight_Jelly_1_Win

然后，当想要获得金币或奖励时，请执行以下操作：

:Fight_Jelly_1_Win
cls
echo The fight was easy and you found some gold!
pause
set gold=0 (if you didn't have a gold variable)
set /a gold=gold+5 (to add gold)
goto FRAMENAME

我希望我帮忙！

Answer 2

假随机 - 我确认％random％由系统时钟 - http://blogs.msdn.com/b/oldnewthing/archive/2010/06/17/10026183.aspx

驱动

使用时钟MS获得1到1000的随机数这是一种获得毫秒的方法：https://answers.yahoo.com/question/index?qid=20100816021807AAz6eL3

引入随机性的另一种可能性是启动游戏，然后等待用户输入，即准备开始？＆＃34;当它们启动时会在cmd.exe启动后的时间内引入一些随机性。

Answer 3

我强烈怀疑您设置了变量random。如果您已完成此操作，则您在环境中设置的值将覆盖该魔术变量。

您可以按set "random="

清除它

在setlocal之后使用@echo off是正常做法。这样，当批次终止时，您对环境所做的任何更改都将被撤消。如果没有它，任何所做的更改都将保留，直到它们再次被明确更改为止。

就个人而言，我更喜欢

设置/值=％随机％%%限制+ 1

生成值1..limit。如果没有其他原因，输入起来会更容易。

@echo off
setlocal
rem environment changes made after here will be backed-out when the batch finishes...
....whatever....

setlocal命令设置了本地＆＃39;只有在批处理结束或遇到endlocal命令时才存在的环境。

请在提示中查看setlocal /?以获取更多信息。

我添加win_fight_1例程后，您的批处理似乎正常。

但请注意，批次将在set /p answer = = (1)continue or (2)quit?上进行限制，但删除其中一个 = 将解决它。

除此之外，只需观察您是否要转到menu或start_1。

和

if %f2% gtr 4 goto fight_2
if %f2% lss 1 goto fight_2

将无效 - 当然，如果您已使用set /a f2=%random% %% 4 + 1

为什么我的CMD / Batch游戏不起作用？
