无法有条件地在批处理脚本中更改变量

Question

这个批处理脚本总是给出答案“你做一些0”而不是其他选项。 我在这里做错了什么？

set /a foodcalc=0
set /a dish=0
set /a food1=1   
set /a food2=2    
set /a food3=3    
set /a food4=4    
SET /a foodcalc=4*%random%/32768+1    
IF foodcalc==1 set /a dish food1    
IF foodcalc==2 set /a dish food2    
IF foodcalc==3 set /a dish food3    
IF foodcalc==4 set /a dish food4
echo You make some %dish%.    
ping localhost -n 3 >nul    
goto actualgame

Answer 1

需要使用％来引用变量的内容，这样

     if %foodcalc%==1 echo one!

Answer 2

IF %foodcalc%==1 set /a dish=food1
IF %foodcalc%==2 set /a dish=food2
IF %foodcalc%==3 set /a dish=food3
IF %foodcalc%==4 set /a dish=food4
