Question

我正在尝试封装基于sprite的游戏，但我无法访问具有相同命名空间的类。以下是命名空间的代码：

namespace Client
{
    public class Bomb : public Entity
    {
    private:
        int tiempo;
        TipoBomba tipo;
    public:
        Bomb(int px, int py, int tiempo, TipoBomba tipo);
        int getX();
        int getY();
        int getTiempo();
        void setTiempo(int t);
        Client::TipoBomba getTipo();
        void reducirTiempo();
        void Mostrar(Graphics ^ gr);
        void explotar(Graphics ^ gr);
    };
    public class Game
    {
        int nivel;
        LivingEntity* objJugador;
        //Enemigo* objEnemigo;
    public:
        ~Game(void);
        Game(void);
        static int ** matriz;
        static std::vector<Bomb*> bombas;
        static bool isBloque(int px, int py);
        static bool isVacio(int px, int py);
        static void romperBloque(int px, int py, Graphics^ gr);
        static bool isRompible(int px, int py);
        static bool isBomba(int px, int py);
        Point getPrimeraPosicionJugador();
        static void addBomba(Bomb* b);
        static void cargarMatriz();
        void setDireccion_Jugador(Direccion dir);
        void Crear_Enemigo(int px, int py);
        void Crear_Jugador(int px, int py);
        void Mover_Entidades(Graphics^ gr);
        Client::Player* getJugador();
        int getNivel();
        void setNivel(int n);
    };
    public class Player : public LivingEntity
    {
        int vidas;
        int bombas;
    public:
        Player(void);
        Player(int px, int py);
        void Mostrar(Graphics^ gr);
        void Mover(Graphics^ gr);
        int getVidas();
        int getBombas();
        void setBombas(int bombas);
        void setVidas(int vidas);
    };
    public class Enemy : public LivingEntity
    {
    public:
        ~Enemy(void);
        Enemy(void);
        Enemy(int px, int py);
        void Mover(Graphics^ gr);
        void Mostrar(Graphics^ gr);
    };
    public enum TipoBomba
    {
        BASICA,
        GRANDE
    };
}

警告是：

Warning 60 warning C4183: 'getJugador': missing return type; assumed to be a member function returning 'int'
Warning 37 warning C4183: 'getTipo': missing return type; assumed to be a member function returning 'int'

错误是：

Error 6 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
Error 10 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

我尝试从Client :: Player更改为Player（与TipoBomba相同）并且它不起作用。我也尝试在课前公开，但仍然一样。我需要使用任何类型的关键字，还是命名空间语义？。谢谢

一切正常，无论是谁，现在我在编译时都会遇到很多LINKER错误。例子：

Answer 1

C ++编译器逐行评估事物。（这是一个过于简单化，但足够接近这个讨论。）当它到达声明getJugador的那一行时，它对Client::Player类型一无所知，因为它没有＆＃t; t到了那儿！

有几种方法可以解决这个问题：

您可以添加类的前向声明。 public class Player : public LivingEntity;告诉编译器＆＃34;有一个名为Player的类，我将声明后面的内容＆＃34;。
您可以重新安排您的课程定义，以便他们按顺序排列。对另一种类型的任何引用都是文件中较早的类型。
（推荐）将您的类分隔为自己的头文件。 #include需要任何其他类定义。只要您没有任何循环引用，就可以处理它。

其他事项：

由于您的参数类型为Graphics^，因此您可以在此处使用C ++ / CLI。鉴于此，我高度高度建议你让你的课程管理。将类定义为public ref class，并始终将变量和参数声明为MyClass^。
一般来说，在编写C ++ / CLI时，我建议采用更高级语言的方式，即C＃。所以托管类就像我说的那样，使用.Net库而不是C ++库。

命名空间和clases嵌套问题
