Question

我正在使用SFML1.6来制作图形应用程序（游戏）。当我只有一个文件超出主文件时，它工作正常。现在我添加了一个新文件Level，我收到了这些错误：

C:\Users\...\Window.hpp|6|error: 'RenderWindow' in namespace 'sf' does not name a type|
C:\Users\...\Window.hpp|7|error: 'Image' in namespace 'sf' does not name a type|
C:\Users\...\Window.hpp|8|error: 'Sprite' in namespace 'sf' does not name a type|
C:\Users\...\Window.hpp|9|error: 'Color' in namespace 'sf' does not name a type|

由于它工作正常，我认为这是由于新文件：

Level.cpp

#include <SFML/Window.hpp>
#include <iostream>

#include "Window.hpp"

class Level
{
     sf::Window* pResultScreen;
     public:
     Level( sf::Window& );
}; 

Level::Level( sf::Window &app)
{
     pResultScreen = &app;
};

Level.hpp

#ifndef Level_hpp
#define Level_hpp

class Level
{
     sf::Window* pResultScreen;
     public:
     Level( sf::Window& );
};

#endif

有没有人发现上述代码存在问题？

编辑： Window.cpp

您应该将#include <SFML/Window.hpp>放入头文件中，因为您需要在其中定义。（然后源文件应该包含标题而不是复制其内容

命名空间'sf'中的X未命名类型
