如何批量创建嵌套变量? [英] How to create nested variables in batch?

问题描述

我正在尝试创建的批处理游戏中获取嵌套变量. 我希望它可以选择一个随机变量并将其更改为X，但是如果已经选择它，则应返回并选择另一个数字.

I am trying to get nested variables in my batch game i am creating. I want it so that it will choose a random variable and change it to X, but if it is already chosen, it should go back and choose a different number.

set 1=a
set 2=b
set 3=c
set 4=d
set 5=e

这些是变量，这是代码

setlocal enabledelayedexpansion

:eliminator
set /a eliminate=(%random * 5) / 32767 + 1
if %%eliminate%%==X goto eliminator
echo The letter !!eliminate!! was chosen
timeout 5
set %%eliminate%%=X
goto eliminator 

现在，事情是，当我尝试回显它时，它会写出变量的名称而不是值.同样，已经选择的变量将再次被选择.有什么办法可以解决这个问题吗?谢谢.

Now, the thing is, when I try to echo it, it writes the name of the variable instead of the value. Also, variables that have already been chosen are being chosen again. Any way I could fix this? Thanks.

推荐答案

尝试一下:

@echo off&setlocal
set "var1=a"
set "var2=b"
set "var3=c"
set "var4=d"
set "var5=e"
:loop
set /a rd=%random%%%5+1
if defined var%rd% call echo %%var%rd%%%
set "var%rd%="
set "var" >nul 2>&1 && goto:loop

..输出(可能有所不同):

..output (may vary):

d
a
c
b
e
