请在批处理脚本中提供一些帮助

I made a game menu and the "2" works gret but when i click "5" it adds +1 to "menumark" BTW I have Windows 7. Some more questions: 1) Can you put a color to a specific letter? 2) Why doesnt: if errorlevel 3 set /a menumark=%menumark%-1 work? Code:

Your problem is the control of errorlevel. The code if errorlevel n command will execute the indicated command for any errorlevel value greater or equal to n. For this reason, to use this kind of testing it is necessary to test from greater to lower values of errorlevel and properly code to avoid problems

你的问题是对errorlevel的控制。如果errorlevel n命令的代码将对任何大于或等于n的errorlevel值执行指示的命令。出于这个原因,要使用这种测试,有必要从更高到更低的errorlevel值进行测试并正确编码以避免出现问题

if errorlevel 3 echo 3
if errorlevel 2 echo 2
if errorlevel 1 echo 1

if your errorlevel is 3, the previous code will echo the three values, as all the conditions are evaluated to true.

如果您的errorlevel为3,则前面的代码将回显这三个值,因为所有条件都被计算为true。

if errorlevel 3 (
    echo 3
) else if errorlevel 2 (
    echo 2 
) else if errorlevel 1 (
    echo 1
) else echo no error level


if %errorlevel%==3 echo 3
if %errorlevel%==2 echo 2
if %errorlevel%==1 echo 1

Both versions will avoid the "problem" (or you can use gotos to avoid falling through the options)

两个版本都将避免“问题”(或者您可以使用gotos来避免掉落选项)
