我的问题可能有一个简单的答案，但它困扰着我，因为我似乎无法让它正常工作，尽管它看起来对我来说是正确的。正如我在标题中所看到的，当我用右键点击标志时它会起作用，但当我击中地雷时，它会结束游戏，而不是将标志放在广场上，并允许我继续游戏。 任何帮助，将不胜感激。 编辑：编辑代码，并添加了两个布尔语句的大括号，但我遇到的主要问题是，当我右键点击我想放置一个标志的正方形，它是一个矿，它的行为如同该矿被击中，然后该程序在5秒后完成并退出。如果有人可以帮助我，当我点击右键放置一面旗子时，它不会炸毁我的地雷，我真的很感激它。 我的代码如下，它被注释掉大部分：C++ SDL扫雷艇标记结束游戏当击中炸弹

是的，我之前做过，但由于某种原因，我决定摆脱大括号，并改回到之前的样子，所以谢谢。 – Sollux
是否解决了这个问题？如果是这样，请接受答案。如果没有，请展开剩余的问题并更新问题。 – Jfevold
它没有，我更新了我对问题和代码的描述。 – Sollux
