在If命令后设置命令

Question

试图制作一个测验show.bat文件并在If-Set编码时遇到问题:

:10    
echo @: (Press any key to continue)
pause >nul
cls
echo Bonus Question 1:
echo Translate the letters in CAPS.
echo @: Copy the sentence and translate the words in CAPITALS.
echo Il nome di mia ZIA e Gabriella e il nome di mio ZIO e Nick.
echo @: Careful, you only get 3 goes!
echo @: now you try!
set /p BonusAnswer1=">"
set /p BonusAnswer1=">"
if "%BonusAnswer1%"=="Il nome di mia aunty Gabriella e il nome di mio uncle Nick. echo well done! &goto:11
if "%BonusAnswer1%"=="Hint" echo @: Copy the sentence and translate ZIA and ZIO. Only put a capital for Il, Gabriella and Nick. &goto:10

这是我遇到问题的地方:

if "%Bonus1Tries%"=="3" set Bonus1Tries=2 &echo you only have %Bonus1Tries% left!

该编码中唯一不起作用的部分是:

you only have 3 tries left!

代替

you only have 2 tries left!

意思就是

设置Bonus1Tries = 2

不工作.你能帮忙吗,并提前感谢你!-Batch Man

Answer 1

在您需要的代码块内delayed expansion，或者拆分命令（如果可能）：

if "%Bonus1Tries%"=="3" set "Bonus1Tries=2"
if "%Bonus1Tries%"=="2" echo you only have %Bonus1Tries% left!
