C++ SDL 扫雷器在击中炸弹时标记结束游戏

Question

我的问题可能有一个简单的答案，但它难倒了我，因为尽管它对我来说看起来是正确的，但我似乎无法让它正常工作。正如标题中所读，当我使用右键单击放置旗帜时它有效，但是当我击中地雷时它会结束游戏而不是将旗帜放置在广场上并允许我继续游戏。 任何帮助，将不胜感激。 编辑:编辑了代码并为两个 bool 语句添加了大括号，但我遇到的主要问题是，当我右键单击我想放置一个标志的方 block 时，它是一个地雷，它充当如果地雷被击中，程序将继续运行并在 5 秒后退出。如果有人能帮助我解决当我右键单击放置旗帜时不会炸毁地雷的问题，我将不胜感激。 我的代码在下面，大部分都被注释了:

Answer 1

                    if ((mines[MouseX][MouseY][0]==9)&&(mines[MouseX][MouseY][0]==10)) //so it kills the program despite 
                    lose=false; //the bool statements

                    break;

我猜您打算将条件 (if) 应用于 lose=false; 和 win=false; 行, 但如所写，它仅控制第一条语句。像这样添加大括号:

                    if ((mines[MouseX][MouseY][0]==9)&&(mines[MouseX][MouseY][0]==10)) //so it kills the program despite 
                    {
                        lose=false; //the bool statements
                        win=false;
                    }
                    break;
