我正在尝试为cmd制作基于文本的游戏，每当我尝试输入响应时，会立即关闭，我几乎无法读出＆＃34; goto此时出乎意料＆＃34;

Answer 1

您未正确形成测试。您需要将变量括在双引号中：

if "%input%" == "1" goto Feel
if "%input%" == "2" goto Listen

请注意，在这些之后你需要额外的条件来处理他们没有输入1或2的可能性。

您应该考虑使用choice命令而不是set /p。从命令提示符处键入choice /?。

将来，如果您在提前终止时遇到问题，请从命令提示符运行脚本。这样窗口就不会关闭，你将有足够的时间来阅读错误。

您可以按 - R 快速运行命令提示符，输入cmd并按 Enter

Answer 2

您应该删除input命令中=和set之间的空格，否则您实际上是在设置名为input　的变量（位置为{1}}结束）。这按预期工作：

echo 1.) Feel around you
echo 2.) Listen for anything else
set/p input=Command?
if %input% == "1" goto Feel
if %input% == "2" goto Listen
echo.
echo.
:Feel
echo You feel around and hear a growl.
echo As you realize the scratching was
echo on your leg.
echo. 
echo You remember nothing else.

但是，如果用户输入带有空格的输入，则%input%周围没有引号会产生unexpected goto错误。 paddy建议使用选择命令可能是要走的路。
