问题描述

我正在尝试进行一点四连环游戏，每当我按Enter键而没有在控制台中键入任何内容时，它都说goto此时是意外的，如果没有，我现在想要的所有操作都将返回:X.用户输入.任何帮助将不胜感激.

解决方案

如果您输入的是带有 set/p 的字符串，则无需说输入的数据不包含空格.解决该问题的方法是将比较运算符两边的字符串都用引号引起来" -即，将双引号'不是单引号'

IF语法是string1运算符string2操作.

您需要

 如果％possibleemptyvariable％" =="1"转到... 

I am trying to make a little connect four game and whenever I hit enter without typing anything into the console it says that goto was unexpected at this time All I want it to dos go back to :X for now if there is no user input. Any help would be aappreciated.

解决方案

If you are entering a string with a set/p, then there's no saying that the data entered doesn't contain Spaces. The way to get over that is to "enclose the strings on both sides of the comparison operator in quotes" - that is, double-quotes 'not single quotes'

IF syntax is if string1 operator string2 action.

You need

if "%possiblyemptyvariable%"=="1" goto ...
