loops - [批处理]循环直到按下一个键

Question

我想在这里做的是循环直到按下“x”。我知道 CHOICE 带有 /T 选项。

但是 CHOICE 对我要播放的动画的超时时间太长。这是一个例子:

@echo off
cls
set frame=2
:loop
cls
type [%frame%].txt
[Here is where it would test for the keystroke.If keystroke "x" is detected,goto MENU. If not pressed within a quick second,continue.]
set /a frame=%frame%+1
goto loop

注意:帧是用于动画的，所以请记住超时必须相当快。

Answer 1

这是一个旧世界的解决方案，但使用 Windows certutil 创建一个存储在批处理文件中的可执行文件 - 当按下空格键时可执行文件退出循环。

大多数人会认为它有点冒险，因为可执行文件可以做任何事情，而且您必须盲目相信我不会损坏您的 PC。尽管如此，我还是将它添加到此处作为替代方案，您始终可以自己编译可执行文件并使用它创建 certutil 脚本。

下面的脚本是一个 PureBasic 脚本，如果按下空格键，它只会创建一个零字节文件。

OpenConsole() 
String$ = Inkey()
If string$=" " 
  CreateFile(0, "quit.tmp")
  EndIf

下面的这个批处理文件创建了一个 quit.exe 文件，它是我从上面的脚本编译而来的，并展示了如何在循环中使用 quit.exe。

在按下空格键之前它什么都不做，然后退出循环。

@echo off
call :create_quit.exe
:loop
quit
if exist quit.tmp del quit.tmp & goto :exit
goto :loop
:exit
echo reached the end
del quit.exe
pause
goto :EOF


:create_quit.exe
