批处理如果存在命令

Question

我想保存一个游戏，它会卡住。当我按ENTER它会留下一个空白点。有人在我的剧本中看到错误吗？

@echo off 
:saveload 
title player movement 
color 0f 
cls 
set /a health=10 
if exist saves.txt (
    < saves.txt (
     set /p weapon= 
     set /p armorh= 
     set /p armorc= 
     set /p armorl= 
     set /p armorf= 
     set /p bow= 
     set /p gold= 
     set /p dmgweapon= 
     set /p dmgbow= 
     set /p prtah= 
     set /p prtac= 
     set /p prtal= 
     set /p prtaf= 
     set /p name= 
    ) 
    goto :varsetup 
) else (
    echo to first begin we need to get your name! 
    set /p name=What is your name?: 
    (
     set /p armorh=n/a 
     set /p armorc=n/a 
     set /p armorl=n/a 
     set /p armorf=n/a 
     set /p bow=n/a 
     set /p gold=10 
     set /p dmgweapon=1 
     set /p dmgbow=0 
     set /p prtah=0 
     set /p prtac=0 
     set /p prtal=0 
     set /p prtaf=0 
     set /p name=%name% 
    ) > saves.txt 
    goto :saved 
) 
:saved

在set /p name=后您的else分支，而不是set /p foo=bar需要说明echo bar，据我得到了你的意图。 if exist不应该是这里的问题。这里是固定的代码：

@echo off 
:saveload 
title player movement 
color 0f 
cls 
set /a health=10 
if exist "saves.txt" (
    < "saves.txt" (
     set /p weapon= 
     set /p armorh= 
     set /p armorc= 
     set /p armorl= 
     set /p armorf= 
     set /p bow= 
     set /p gold= 
     set /p dmgweapon= 
     set /p dmgbow= 
     set /p prtah= 
     set /p prtac= 
     set /p prtal= 
     set /p prtaf= 
     set /p name= 
    ) 
    goto :varsetup 
) else (
    echo to first begin we need to get your name! 
    set /p name=What is your name?: 
    (
     echo n/a 
     echo n/a 
     echo n/a 
     echo n/a 
     echo n/a 
     echo 10 
     echo 1 
     echo 0 
     echo 0 
     echo 0 
     echo 0 
     echo 0 
     echo %name% 
    ) > "saves.txt" 
    goto :saved 
) 
:saved
