If statement 在If命令之后设置命令

正在尝试制作quicky show.bat文件，但在If Set编码方面遇到问题：

: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

这就是我的问题所在：

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

编码中唯一不起作用的部分是：

you only have 3 tries left!

而不是

you only have 2 tries left!

也就是说

设置Bonus1Tries=2

它不起作用了。

请你帮忙，提前谢谢你-批处理人员

您必须启用延迟扩展

SETLOCAL ENABLEDELAYEDEXPANSION
set VAR=before
set VAR=after & echo immediate:%VAR%, delayed:!VAR!
ENDLOCAL

如

所述，在代码块中，您需要延迟扩展，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!
