c++ - 标题困惑。编译器不识别数据类型

Question

我对为什么编译器不能识别我的类感到困惑。所以我将向你们展示我的代码，让你们决定。我的错误是这样的

error C2653: 'RenderEngine' : is not a class or namespace name

它指向这条线

std::vector<RenderEngine::rDefaultVertex> m_verts;

这是 rModel 的完整代码。它包含变量。持有它的类(class)更远。

#ifndef _MODEL_H
#define _MODEL_H
#include "stdafx.h"
#include <vector>
#include <string>
//#include "RenderEngine.h"
#include "rTri.h"

class rModel {
public:

    typedef tri<WORD> sTri;

    std::vector<sTri> m_tris;
    std::vector<RenderEngine::rDefaultVertex> m_verts;

    std::wstring m_name;

    ID3D10Buffer *m_pVertexBuffer;
    ID3D10Buffer *m_pIndexBuffer;

    rModel( const TCHAR *filename );
    rModel( const TCHAR *name, int nVerts, int nTris );

    ~rModel();

    float GenRadius();
    void Scale( float amt );
    void Draw();

    //------------------------------------ Access functions.
    int NumVerts(){ return m_verts.size(); }
    int NumTris(){ return m_tris.size(); }
    const TCHAR *Name(){ return m_name.c_str(); }

    RenderEngine::cDefaultVertex *VertData(){ return &m_verts[0]; }
    sTri *TriData(){ return &m_tris[0]; }

};

#endif

在代码的最顶端有一个头文件

#include "stdafx.h"

包括这个

// stdafx.h : include file for standard system include files,
// or project specific include files that are used frequently, but
// are changed infrequently
//

#include "targetver.h"

#define WIN32_LEAN_AND_MEAN             // Exclude rarely-used stuff from Windows headers
// Windows Header Files:
#include <windows.h>

// C RunTime Header Files
#include <stdlib.h>
#include <malloc.h>
#include <memory.h>
#include <tchar.h>
#include "resource.h"
#include "d3d10.h"
#include "d3dx10.h"
#include "dinput.h"
#include "RenderEngine.h"
#include "rModel.h"


// TODO: reference additional headers your program requires here

如你所见，RenderEngine.h 出现在 rModel.h 之前

#include "RenderEngine.h"
    #include "rModel.h"

据我所知，应该是可以识别的。但另一方面，我不太擅长组织标题。这是我的 RenderEngine 声明。

#pragma once
#include "stdafx.h"



#define MAX_LOADSTRING 100
#define MAX_LIGHTS 10

    };

    class rLight
    {
    public:
        rLight()
        {

        }
        D3DXCOLOR m_vColor;
        D3DXVECTOR3 m_vDirection;
    };

    static HINSTANCE m_hInst;
    HWND m_hWnd;
    int m_nCmdShow;
    TCHAR m_szTitle[MAX_LOADSTRING];                    // The title bar text
    TCHAR m_szWindowClass[MAX_LOADSTRING];          // the main window class name

    void DrawTextString(int x, int y, D3DXCOLOR color, const TCHAR *strOutput);

    int Run();
    void ShutDown();

    void AddLight(D3DCOLOR color, D3DXVECTOR3 pos);

    RenderEngine()
    {
        m_screenRect.right = 800;
        m_screenRect.bottom = 600;
        m_iNumLights = 0;
    }

    RECT m_screenRect;

    ATOM RegisterEngineClass();
    void DoFrame(float);
    bool LoadEffects();
    void UpdateMatrices();
    void UpdateLights();

};

类在类中定义

class rDefaultVertex
        {
        public:
            D3DXVECTOR3 m_vPosition;  
            D3DXVECTOR3 m_vNormal;
            D3DXCOLOR m_vColor;
            D3DXVECTOR2 m_TexCoords;
        };

        class rLight
        {
        public:
            rLight()
            {

            }
            D3DXCOLOR m_vColor;
            D3DXVECTOR3 m_vDirection;
        };

不确定这是否是好的做法，但我只是照章办事。

最后，我只是需要一个好的组织方式，让rModel识别RenderEngine。如果可能的话，反过来。

我可以直接指向渲染引擎类，但它仍然无法识别

#ifndef _MODEL_H
#define _MODEL_H
//#include "stdafx.h"
#include <vector>
#include <string>
#include "RenderEngine.h"  //<-------pointing to render engine. still does not recognize.
#include "rTri.h"

class rModel {
public:

    typedef tri<WORD> sTri;

    std::vector<sTri> m_tris;
    std::vector<RenderEngine::rDefaultVertex> m_verts;

    std::wstring m_name;

    ID3D10Buffer *m_pVertexBuffer;
    ID3D10Buffer *m_pIndexBuffer;

    rModel( const TCHAR *filename );
    rModel( const TCHAR *name, int nVerts, int nTris );

    ~rModel();

    float GenRadius();
    void Scale( float amt );
    void Draw();

    //------------------------------------ Access functions.
    int NumVerts(){ return m_verts.size(); }
    int NumTris(){ return m_tris.size(); }
    const TCHAR *Name(){ return m_name.c_str(); }

    RenderEngine::cDefaultVertex *VertData(){ return &m_verts[0]; }
    sTri *TriData(){ return &m_tris[0]; }

};

#endif

正如其他人提到的，这里需要进行解耦/重构 - stdafx.h 并不意味着要保存所有 头文件 您的应用程序有。

您的问题是 renderengine.h 还包括 stdafx.h。这次 renderengine.h 包含由于 #pragma once 而被忽略，接下来包含 rmodel.h - 在 的顶部renderengine.h.

在您的情况下，最简单的事情是:

• 从 stdafx.h 中删除 renderengine.h 和 rmodel.h
• rmodel.h 包括 renderengine.h
• ... 完成
