切换语句切换到案例2时应切换到情况1

Question

我有一个带有菜单的游戏，当我访问菜单时，我将带我到其他sf::View，当我退出菜单时，应该将我返回我当前正在使用的sf::View开关和案例语句。与其带我回到currentroom，当我在StartRoom中时应该设置为1并访问菜单，而是将我放在LevelTwo中并运行Room2()。因此，当我在第一个房间里时，当前房间以某种方式从1到2，因此，当我按下'Q'访问菜单时，它会将我返回到Room2而不是Startroom。同样，当我用WhatRoom(1);替换WhatRoom(currentroom);时，也会发生同样的事情，它运行Room2((，然后将我发送到第二个房间。感谢您的任何帮助，如果您有任何疑问，我会尽力回答。

您在case StartRoom:分支末尾缺少break。进入此功能：

void WhatRoom(int TheLevel){
    switch (room){
        case StartRoom:
            currentroom = 1;
            window.setView(start);
            backround.setTexture(dungeon);
            if (TheLevel == 2){
                LevelOne = false;
                cout << "hello";
                room = LevelTwo;
                break;
            }
        /*
            At this point you should break this branch, otherwise
            case LevelTwo brach will be executed too
        */
        case LevelTwo:
            cout << "HELLO";
            currentroom = 2;
            backround.setTexture(generalback);
            Room2();
            break;

    }
};

这是开关语句中常见的错误。我建议您始终写下所有可能的案例。

在某些特殊情况下，您可能需要删除那些break行。
