尝试读取枚举状态时出现 C++ 枚举错误

Question

我正在用 C++ 制作游戏，但我遇到了枚举问题。我正在定义一个枚举:

enum class CharacterClass {
    warrior = 0,
    scout = 1,
    mage = 2
};

我在 Player 类中使用它:

class Player
{
    public:
        Player();
        ~Player();

        CharacterClass PlayerClass;

    private:
};

当我尝试设置枚举的状态时:

Player player();
player.PlayerClass = CharacterClass::mage;

编译器发现这个错误:

request for member 'PlayerClass' in 'player', which is of non-class type 'Player()'

Answer 1

这是最vexing parse : player 理解为函数声明。所以 player.PlayerClass 触发了这个错误。

尝试:

Player player{};  // prefer uniform brace-initialisation 

此博客条目关于 variable initialization很好地解释了每种形式的优缺点。
