Variables 如果变量=0，则批处理不检查

所以，我用批量编码制作了一个游戏，我在游戏中有一个商店，每个商店只卖一件物品。不幸的是，当我将项目的变量设置为1，然后将其减少为0时，代码不会确认没有更多的项目要出售

:ForestHagShop
cls
set WSwrdHag=1
set WShldHag=1
set GldApHag=1
echo "What would you like, my dear?"
echo 1.) Wooden Sword  - 50 gold - (+10 Attack)
echo 2.) Wooden Shield - 70 gold - (+30 Max HP)
echo 3.) Shiny Apple   - 40 gold - (+30 HP)
echo.
set /p input6=)
if %input6% equ 1 goto BuySwrdHagChk
if %input6% equ 2 goto BuyShldHag
if %input6% equ 3 goto BuyAplHag

:BuySwrdHagChk
echo Checking...
echo.
echo **PRESS A KEY**
Pause >nul
if WSwrdHag LSS 1 goto OutSwordHag

:BuySwrdHag
set /a Gold=Gold-50
set /a Attack=Attack+10
set /a WSwrdHag=WSwrdHag-1
echo You hand over 50 gold for the
echo wooden sword. Your new stats are...
echo Health Points .. .. .. %HP%/%MaxHP%
echo Gold .. .. .. .. .. .. %Gold%
echo Attack Power  .. .. .. %Attack%
echo.
echo **PRESS A KEY**
pause >nul
goto ForestHagShop

:OutSwordHag
echo The hag frowns, looking at you like
echo you're stupid. 
echo "You already bought my wood sword,
echo idiot!"
echo.
echo **PRESS A KEY**
pause >nul
goto ForestHagShop

这把剑仍在库存中，而且会无限循环。。D:这是因为在：BuyswrdHag结束时，您将bak循环到ForestHagShop，在那里您将WSwrdHag重置为1…..您对
